A kind of eucalyptus seedling medium and production technique thereof
Technical field
The present invention relates to seeding raising technology, specifically be meant a kind of eucalyptus seedling medium and production technique thereof.
Background technology
Seedling medium is used to replace soil to grow seedlings in modern agriculture, forestry, because seedling medium is than the easier control nutrient composition content of normal soil, and easier accomplishing scale production, thereby be used widely gradually.
Chinese patent discloses a kind of " compact type substrate seedling nursery culture pan " for No. 200510061570.2, and the composition proportioning of its alms bowl material is: peat 35~40, wooden nutrient substance 20~25, feces of livestock and poultry 15~20, attapulgite 20~25, composite bacteria 0.2~0.3.With 100 kilograms of nutrition pots of every production is example, must be the wooden nutrient substances of 30~50 purposes with 20~25 kilograms of specifications, with 15~20 kilograms feces of livestock and poultry, and 0.2~0.3 kilogram of high temperature resistant fermented bacterium mixing, stir; Under 50 ℃~70 ℃ temperature condition, carry out aerobic fermentation, fermentation time is 15~25 days; Add 35~40 kilograms again and be crushed to 5~20 purpose peat, 0.2~0.3 kilogram composite bacteria, 20~25 kilograms attapulgite, mixing and stirring is sent into earthen pot maker compression moulding.
In above-mentioned " compact type substrate seedling nursery culture pan ", the peat usage quantity is bigger, and cost is higher.In addition, described wooden nutrient substance mainly is from plant duff and vegetable garbage, is the powder mixture of things such as dry fruit shell, vegetable fibre and timber bits; Wherein the dry fruit shell be in nut-shell, Pericarppium arachidis hypogaeae, melon seed cases, the cotton seed hulls any one, the bar fibres is in reed rod, sedge, crop stalk, corn cob, the bagasse any two kinds; Contained composition has Mierocrystalline cellulose, hemicellulose, xylogen, fruit matter glue, natural gum, tannin, protein, pigment, fat, resin, rrna and several mineral materials.The more complicated of drawing materials of this wooden nutrient substance, its nutritive ingredient and content are difficult to effective control.
Summary of the invention
The invention provides a kind of eucalyptus seedling medium and production technique thereof, its main purpose is to overcome that existing seedling medium cost is higher, nutritive ingredient and content are difficult to the effectively shortcoming of control.
The present invention adopts following technical scheme:
A kind of eucalyptus seedling medium, each component that comprises following weight ratio: coconut shell flour 35-40, peat 25-30, wilkinite 15-20, attapulgite 20-25, water-loss reducer of soil 0.5-0.8, nutritive substance 15-20, composite bacteria 0.2-0.3, and this seedling medium is block.
Aforementioned composite bacteria is made up of in actinomycetes, genus bacillus, Kazakhstan time Trichoderma, yeast, milk-acid bacteria, vinelandii, phosphate solubilizing bacteria, the potassium solubilizing bacteria any one or a few.
Its production technique comprises:
1) coconut husk is reeled off raw silk from cocoons handles the back and produce chip to pulverize, be sized to granularity be the 10-20 order, carry out the desalinization of soil by flooding or leaching then and handle;
2) be that the high temperature resistant fermented bacterium that the coconut shell flour after the above-mentioned desalinization of soil by flooding or leaching of 35-40 is handled, nutritive substance that weight ratio is 15-20 and weight ratio are 0.2-0.3 mixes with weight ratio, add clear water and stir moisteningly, stack into truncated cone-shaped and overlay film and make its fermentation;
3) fully to add weight ratio be that be crushed to the 5-20 purpose peat, weight ratio of 15-20 is that composite bacteria, the weight ratio of 0.2-0.3 is that 15-20 wilkinite, weight ratio 20-25 are attapulgite and weight ratio 0.5-0.8 water-loss reducer of soil in the fermentation back, mixing and stirring is sent into molding machine and is pressed into bulk.
The height of aforementioned truncated cone-shaped fermentation heap is a 0.5-0.6 rice, and the end face diameter is 1.5 meters, and the bottom surface diameter is 2 meters.
During the fermentation, detect the core temperature of fermentation heap, when this temperature reaches 70 ℃, carry out turning, and it is moistening to add the water maintenance; Fermentation total time is 18-22 days, and the turning number of times is 1-2 time.
Aforementioned nutritive substance is a feces of livestock and poultry.
By the above-mentioned description of this invention as can be known, compare with prior art, the present invention has following advantage:
One, adopt coconut shell flour as main raw material, it draws materials single, draws materials easily, and coconut shell flour is a degradation material, and renewable resources meets the ecological, environmental protective requirement.
Two, reduce the content of peat, thereby reduced the cost of material.
Three, owing to only adopt coconut shell flour as main raw material, so its nutritive ingredient and content controls easily, carries out large-scale standardized production easily.
Four, seedling medium is blocky design, transportation, carrying and easy to use; Can be with piece directly to transplant, not hinder root, no seedling-slowing stage, the transplanting survival rate height, eucalyptus seedling stalwartness, well developed root system, the cauline leaf of cultivating is thick, the drought resisting resistance against diseases is strong.
Five, be added with water-loss reducer of soil in the matrix, this belt transect piece is transplanted, unslow seedling, doubts the solid piece that looses that is difficult for behind the control water naturally.
Six, the eucalyptus seedling medium adopts integrated technology, substrate block has collection matter material, nutrition, sterilization, disease-resistant, five kinds of functions of container are one, do not need to fetch earth, join fertilizer, composting, spray medicine, dress alms bowl fully, only need water, directly cuttage or transplant tissue cultured seedling and can finish and become to grow seedlings operation, can save 4-6 manually for every mu.
Embodiment
The following describes the specific embodiment of the present invention.
Embodiment one
A kind of eucalyptus seedling medium comprises each component of following weight ratio: coconut shell flour 35, peat 25, wilkinite 15, attapulgite 20, water-loss reducer of soil 0.5, nutritive substance 15, composite bacteria 0.2, and this seedling medium is block.This composite bacteria is made up of in actinomycetes, genus bacillus, Kazakhstan time Trichoderma, yeast, milk-acid bacteria, vinelandii, phosphate solubilizing bacteria, the potassium solubilizing bacteria any one or a few.This nutritive substance is a feces of livestock and poultry.
