Description

Fertilizer composition for preventing kiwifruit canker and preparation method thereof

technical field

The invention relates to the technical field of novel special functional liquid fertilizers used both as fertilizers and pesticides, in particular to a fertilizer-medicine combination for preventing and curing kiwifruit canker and a preparation method thereof.

Background technique

Kiwifruit canker is a devastating infectious disease caused by the "Pseudomonas syringae pathogenic type of kiwifruit" bacteria. The fungus is a low-temperature and high-humidity infecting pathogen, and it begins to spread when the ten-day average temperature reaches above 0°C in spring; when the ten-day average temperature is around 10°C, the disease is very easy to spread in the event of strong wind and heavy rain, continuous rain, and frostbite in winter; When the temperature rose to about 20°C, the germs stopped doing harm. Pathogenic bacteria are spread by media such as wind and rain, insects and gardening tools, and invade and reproduce locally from the outside to the inside from the stomata, water holes, lenticels, or various wounds of young tissues such as host leaves, stems, trunks, and branches. After incubation for 3-5 days, when the conditions are suitable, the number of bacteria will expand exponentially, and overflow from the affected part with the bacterial pus, and continue to spread and spread. The leaves and dry branches of the plant are the main victims. After the leaves are infected, a large number of dense necrotic spots are produced, which seriously hinders photosynthesis and withers early; after the main trunk and main branches are infested, bacteria multiply rapidly in the phloem and subcutaneous cambium And secrete bacterial toxins, resulting in old skin necrosis, new skin not growing, skin dry separation, and nutrient cannot be transported normally, seriously affecting the growth of the host, causing the diseased plants to gradually die. Once the host is infected and there is no special prevention and control, it will relapse every year and will not heal for life until it is weak and dying.

At present, the chemical pesticides or preparations used to prevent and control kiwifruit canker at home and abroad include the following categories:

1. Bacterial disease prevention and control agents: such as copper methamine, basic copper sulfate, copper quinoline, copper thiabyl, copper thiesin, manganese, zinc thiesin, copper succinate and copper rosinate, etc. This type of agent mainly uses copper (Cu), manganese (Mn), zinc (Zn) ions or ion clusters of metal salts, which can harden and inactivate the bacterial protein bactericidal mechanism, and prevent the effect when applied at higher temperatures. It is acceptable, but the penetration is weak when applied at low temperature, and the drug effect and control effect on kiwifruit canker bacteria are poor.

2. Antibiotic bacteria control agent: streptomycin sulfate for agricultural use is commonly used. This medicine is easily decomposed by ultraviolet rays in the air, and can only remain on the plant surface for 2-3 days, and cannot inhibit and kill bacterial infection for a long time.

3. Kiwi fruit special dry-applied medicinal fertilizer "Bosheng fertilizer": This product is currently the most widely used dry-applied anti-canker agent in China. This fertilizer also uses trace element metal salts of boron (B), zinc, iron (Fe) and other bactericidal ingredients, which can harden and inactivate the bacteria protein, is a solid fertilizer with both fertilizer and medicine. When using it, mix fertilizer and water 5:3 to make a paste, and apply it on the trunk of the diseased plant to inhibit the invasion and expansion of pathogenic bacteria. The weak point is that water is used as the carrier with poor permeability. When the climate is dry, the plaster on the trunk is easy to fall off in lumps, and it cannot be used for the prevention and treatment of diseases on leaves and branches.

Example 3

Using the GWQ-D "Example 1" formula product of the present invention, before the spring of 2013, in Caotang Town, Weng'an County, Guizhou Province, the 6-year-old ulcer disease was seriously affected by the prevention and treatment treatment, and good results were obtained. The specific processing method is as follows:

1 General survey of diseased plants in the production disease garden to determine the scope of control and treatment

During the growth period, especially in spring, inspect the trunks, branches, and leaves one by one. Those who are confirmed to have canker symptoms are designated as diseased plants, and marked clearly to provide convenience for identification of key control and treatment plants. If find that the bark girdling necrosis at the main canker lesion place of the plant, cortex and xylem break away from the person, be defined as the dying and incurable diseased plant, should be excavated immediately, can not be included in the radical cure object of the present invention as general infected tree and stay for processing .

For sporadic diseased orchards with a diseased plant rate below 5%, the whole plant of the fruit trees within 10m of the adjacent diseased plants shall be treated; for orchards with an incidence rate of more than 5% but less than 10%, the whole plant of the fruit trees within 20m adjacent to the diseased plants shall be treated; For orchards with a plant rate of more than 10%, all fruit trees in the whole orchard will be treated.

2 Curing of diseased trees

Treatment time: Generally, the time limit is about 60 days after all the leaves of the plants fall in the middle and late December of the following year and before the winter injury in the middle and late February of the following year, but the best time is 10-15 days before and after the winter solstice to the minor cold. If the treatment time is too early, there will be insufficient nutrients flowing to the roots to store and feed the roots, which will easily cause the root system to age;

Processing steps:

(1) Cut and trim slightly. Cut off all the current year's branches with ulcer spots; short cut off the young branches above the middle of the asymptomatic spring shoots and tendrils of the year; combined with plastic pruning, thin out useless weak branches, clustered branches, cross branches and overlapping branches; according to 80 - 90cm distance layout, choose to keep the backbone main side branches, leave 3-4 backbone branches per square meter of frame surface, and leave a short fruit branch at every 10-12cm distance on the backbone branches, so as to meet the needs of the head of the household in the current year. Part of the fruit trees needed.

(2) Scrape off the canker lesions on the trunk and the black corky dead skin on the trunk. Repeat the inspection plant by plant, up and down, and in four directions. If you find obvious and hidden ulcer spots on the bark of the main trunk and branches of the plant, use a pumpkin peeling knife to scrape off the bark of the affected part immediately, revealing the brownish red healthy dermis around the spots and the tender green formation under the dermis. layer; or carve and draw several lines longitudinally on the necrotic bark of the affected part, reaching deep into the xylem.

(3) The medicinal fertilizer is applied to the trunk and branches to disinfect and sterilize. Use "GWQ-D" high-osmosis long-acting slow-release medicinal fertilizer stock solution to smear the peeled wound on the trunk with the above-mentioned knife; or mix GWQ-D stock solution with water 10-20 times, and brush the trunk and main branches vertically up and down and around, It is better to brush the bark wet; use the GWQ-D stock solution to mix with water 100-200 times, and spray all the branches and vines and cuts on the surface of the spray rack after cutting.

(4) Qingzhi Garden. Spray the weeds on the ground with paraquat, and clean up and burn all the fallen leaves, cut treetops, diseased bark scraped off by a knife and dead ground on the soil surface in the diseased garden.

(5) Bury topsoil. After clearing the orchard, the surface soil of the orchard was buried to a depth of 10 cm or less, so as to prevent the possible residual ulcer bacteria in the surface soil from splashing with the wind and rain in the next spring, causing initial infection and damage and spreading.

(6) Apply basal fertilizer. According to the formula of nutrient content in NP ₂ O ₅ -K ₂ O=1:0.5:1.2, while overturning and burying the topsoil, apply 1-1.5kg of fertilizer per plant and bury it in the soil in a circular ditch.

(7) Disinfect the soil surface and survive the winter. Use "GWQ-D" medicinal fertilizer mixed with 400-500 times of water to spray and disinfect the soil surface of the whole garden, and kill the tiny amount of ulcer bacteria that may exist on the soil surface.

(8) Wipe buds and keep shoots in the spring of the following year. In early spring and March of the following year, when the spring buds grow to 3-5cm long, wipe out weak buds, adjacent buds and clustered buds according to the position, distance and level, leaving a single strong bud to protect the fruiting spring shoots.

(9) The medicine protects the young shoots. In spring, summer, and autumn of the following year, when young shoots are sprouting three times, use "GWQ-D" mixed with 400-500 times of water, and spray the front and back sides of the leaves of the whole plant, as well as the trunk and branches until wet, so as to prevent possible cankers Bacteria splash with the wind and rain, and infect the tender tissues of the treated plants. In order to achieve a very significant eradication effect within 1 or 2 years, mid-March to late May is the most critical period of pesticide application and protection, and it can be sprayed 3-4 times every half a month; during June-July, the summer shoots are exposed to high temperature and the disease gradually Stop causing damage, depending on the disease situation, spray 1-2 times; in August-September, during the autumn shoot outbreak period, the pathogen gradually recovers its infection vitality, and it can be sprayed 2-3 times for prevention and control.

(10) Strengthen the dynamic monitoring of disease treatment parks. April to August of the following year is the confirmation period for testing the eradication effect of kiwifruit canker. In the treatment garden, the effect of implementing this technology for one year can be determined by the special symptoms and quantity of the diseased spots on the leaves with "yellow halo" and the affected parts of the diseased spots on the branches with "skin rot and pus".

If a small number of plants are found to have symptoms during the inspection, the diseased branches should be cut off and destroyed in time, and "GWQ-D" mixed with water 200-300 times, spray the newly diseased plants and other diseased plants within 10-15 meters adjacent to them. diseased tree.

3 Farming management of the whole garden

(1) Formulate a management system for the treatment of diseased gardens, and assign special personnel to manage the gardens in different areas. It is strictly forbidden to introduce diseased seedlings, scions, and propagation materials from the diseased area into the project treatment area for grafting or planting.

(2) In the second year after the treatment, in spring, summer and autumn, when the young shoots are sprouting, when spraying with "GWQ-D" medicinal fertilizer to prevent canker disease, add instant boron, calcium nitrate, magnesium nitrate and chloride in an appropriate amount. Zinc and other medium and trace element fertilizers are used as foliar fertilizers, and the effect is good.

(3) Since the third year, the canker disease has been eradicated, and the treatment park carries out annual production management according to conventional techniques.

(4) around the garden area where canker is eradicated, if there are still untreated disease gardens to exist, before these disease gardens are not completely processed according to the present invention, the aforementioned orchards that have been processed and recovered must be treated every year during the tender shoot out period. Use "GWQ-D" fertilizer to prevent, isolate infection, and isolate pathogenic bacteria from re-invasion.

116 large kiwifruit trees were treated with this method, including 85 symptomatic diseased trees with canker lesions on the trunk and branches (72.3% disease rate), and 31 asymptomatic trees. After the treatment, the tree-by-plant detailed investigation in the autumn of the same year showed that the number of symptomatic trees decreased to 9, and the stage eradication effect was 92.2%. In the spring of 2014, the symptomatic trees were treated again, and all the trees were cured after re-examination in autumn.

Compared with 96 large trees in the photo area, there were 69 symptomatic diseased trees (71.8% diseased plant rate) and 27 asymptomatic trees in the first year compared with the same period last year. The number of symptomatic diseased trees increased to 72 in the stage inspection year, of which 4 died; in 2014 In the final investigation in autumn, the total diseased plant rate was as high as 75 plants (78.1% diseased plant rate), and the total dead trees increased to 7 plants.

Example 4

With the GWQ-D type "Example 2" formula product of the present invention, at the same time and in the same place as the above-mentioned Example 3, prevent and treat 2-year-old young kiwifruit ulcer disease light disease gardens, treatment time: mid-December to next year 2 In the first ten days of the month, the plant dormancy period begins.

The specific processing steps are as follows:

1 Treatment of 1-2-year-old seedlings introduced outside the field

(1) Short planting pruning. Regardless of whether it is diseased or not, 3-5 hidden buds are uniformly reserved for each seedling, and the upper tender stems are cut short from the height of 20 cm from the stem base, and the excessive fine roots and fibrous roots are appropriately thinned.

(2) Soak seedlings for sterilization. The short-planted 1-2 year old seedlings are counted and bundled, with the exposed roots facing up and the stems facing down, submerged in 400-500 times the "GWQ-D" fertilizer, soaked for 30-40 minutes, and then taken out to dry naturally.

(3) Standardized colonization. The sloping land is densely planted at a distance of 2.5 × 3 meters (the number of plants per mu is about 90 plants), and the farmland is planted at a distance of 4 × 3 meters (the number of plants per mu is 55 plants) and planted in the new garden.

(4) Chemical protection during growth period, dynamic monitoring. When the spring shoots germinate and grow to a height of 10-15cm in the next year, select a tall and strong shoot as the main stem, and erase the rest. Spray GWQ-D medicinal fertilizer to protect seedlings and prevent diseases during the three growth periods of spring, summer and autumn, and pick tops in time to promote growth.

2 Treatment of plants in diseased orchards of young trees
