A kind of method that improves ornamental plant resistance
Technical field
The invention belongs to ornamental plant resist technology field, be specially a kind of method that improves ornamental plant resistance.
Background technology
Mycorhiza bacterium (mycorrhizal fungi) is a parasymbiosis fungi that can form symbiont in the soil with the young tender part of plant rhizosphere, has resistance (comprising drought resistance, salt-resistance and disease resistance etc.), the promotion seedling growth that improves host plant and strengthens the host to Cd
2+Contamination resistance in heavy metal.Song Fu waits research to think by force, and the survival rate of Mycorrhizal afforestation can reach the once successful effect of afforestation on average more than 95%, is an indispensable biotechnology in the production of forestry.Tang Ming etc. investigate from the mycorrhizal fungi resource the many semiarid zones of NORTHWEST CHINA; Furtherd investigate from the drought resistance influence of mycorrhizal fungi plants such as sea-buckthorns; And inquired into from branch mycorhiza bacterium and improved the sick mechanism of willow antiulcer, promoted the development and utilization of China's mycorhiza resource to a certain extent.As a kind of typical ectotrophic mycorrhiza fungi,
Paxillus involutus(Batsch ex Fr.) Fr. distribution on the Northern Hemisphere is very general, and the inoculation back is than being easier to form mycorhiza.Because
P. involutusCan improve the anti-adversity of host plant effectively, and promote the growth of host plant, exist both at home and abroad
P. involutusThe development and utilization aspect carried out more research, and obtained bigger progress.Quoreshi and Khasa discover, when
P. involutusWith bacterium
Burkholderia cepaciaWhen inoculating together, can improve white poplar significantly
P. tremuloidesWith the face cream poplar
P. angustifoliaTo the absorption of nutritive elements such as N and P, thus the growth that improves root system.Researchs such as Garbaye think,
P. involutusThe mycorhiza that forms can improve significantly
Quercus petraeaWith
Q. roburThe drought-resistant ability of tree.In addition,
P. involutusRadioactive element Cs-137 is also had very strong absorption, and can improve the anti-Cu of host effectively
2+, Cd
2+And Pb
2+Ability Deng heavy metal pollution.Mycorhiza plays positive facilitation to the conversion transportation of the stable and energy of forest ecosystem, and it is a kind of special parasitism that plant and microorganism reach high unity.A large amount of mycorhiza application study both at home and abroad shows that mycorhiza can obviously promote the growth of host plant, improves seedling quality, promotes the absorption of host to nitrogen, phosphorus, potassium, and enhancement of plant resistance is improved host plant rhizospheric environment etc.Whether this useful influence of mycorhiza can be given full play to, and is decided by that can the correctness and the mycorrhizal fungi of mycorrhizal fungi selection effectively infect host plant.As far as different seeds, tree body capacitance, bark relative expansion degree, peroxidase activity, polyphenol oxidase activity and PAL activity index and trees disease resistance or resistance have confidential relation.
Summary of the invention
To the problems referred to above that exist in the prior art, the objective of the invention is to design provides a kind of technical scheme that improves the method for ornamental plant resistance, and it is low to have a cost, and effect is remarkable, natural environmental-protective, advantage such as without any side effects.
Described a kind of method that improves ornamental plant resistance is characterized in that may further comprise the steps:
1) bacterium liquid preparation
Take by weighing mycorhiza bacterium Bao ︰ distilled water=1-3:4-6 according to weight ratio, mix and process mycorhiza bacterium spore suspension;
2) Mycorrhizal is handled
Plant seed is 23-28 ℃ of following vernalization; When showing money or valuables one carries unintentionally, seed in mycorhiza bacterium spore suspension, soaks 5-12min 1/2 the time; Peat is gone in sowing then: nutrition soil volume ratio is that 3-5:1 cultivates in the soil, wait seed sprouting 60-80 days after, again at the mycorhiza bacterium spore suspension with needle cylinder injection 2-6ml/ strain from nursery stock root 2-3cm place; Compress injection place with cultivating the soil covering then; Be cultured to 6-8 and can transplant to any soil after the month and cultivate, evenly spray 2-4L mycorhiza bacterium spore suspension in the Yong Mei ㎡ soil again after the transplanting, after this normal cultivation gets final product.
Described a kind of method that improves ornamental plant resistance is characterized in that the plant seed germination temperature is 24-27 ℃, preferred 25-26 ℃; Soak time is 6-10min, preferred 7-9min.
Described a kind of method that improves ornamental plant resistance is characterized in that cultivating peat in the soil: nutrition soil volume ratio is 4:1.
Described a kind of method that improves ornamental plant resistance is characterized in that injecting the bacterium liquid time and is behind the seed sprouting 65-75 days, and injection bacterium liquid measure is the 3-5ml/ strain.
Described a kind of method that improves ornamental plant resistance is characterized in that transplanting time is to cultivate 6-8 after the month, and bacterium liquid sprinkling amount is 2.5-3L/ ㎡.
Above-mentioned mycorhiza bacterium spore can directly be buied from market.
Above-mentioned a kind of method that improves ornamental plant resistance is a medium with distilled water, is prepared into suspension bacteria liquid with mycorhiza bacterium spore; Bacterium liquid through to ornamental plant seed and seedling is handled; Have and promote the synthetic of seed vitality, raising seedling mycorhiza, promotion seedling growth, the multiple efficacies such as resistance of raising plant; Can effectively resist the generation of various diseases, special efficacy arranged improving sapling resistance.Its natural environmental-protective does not have any pollution to environment, and safe in utilization, and effect is remarkable, and is with low cost, is adapted at the ornamental plant plantation, transplants and cultivates going up using.
The percentage composition that relates in the present specification unless otherwise indicated, other the weight percentage that is pure material.
