Description

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
VA Mycorrhizal Fungi (mycorrhizalfungi) is a parasymbiosis fungi that can form with the tender part of the children of plant rhizosphere homobium in soil, has and improves resistance (comprising drought resistance, salt-resistance and disease resistance etc.), the promotion seedling growth of host plant and strengthen host to Cd2+Deng the contamination resistance of heavy metal. The Song Fu research such as by force thinks, the survival rate of Mycorrhizal afforestation on average, more than 95%, can reach the successful effect of once afforesting, and is an indispensable biotechnology in production of forestry. Tang Ming etc. investigate from mycorrhizal fungi resource the many semiarid zones of NORTHWEST CHINA, further investigate the drought resistance impact on plants such as sea-buckthorns from mycorrhizal fungi, and inquire into the mechanism that improves willow Canker-Resistance from branch VA Mycorrhizal Fungi, promoted to a certain extent the development and utilization of China's mycorhiza resource. As the typical Applying Ectomycorrhizal Fungi of one,Paxillusinvolutus(BatschexFr.) Fr. distribution is on the Northern Hemisphere very general, and inoculation is rear than being easier to form mycorhiza. Due toP.involutusCan effectively improve the anti-adversity of host plant, and promote the growth of host plant, exist both at home and abroadP.involutusDevelopment and utilization aspect carried out more research, and obtained larger progress. Quoreshi and Khasa research discovery, whenP.involutusWith bacteriumBurkholderiacepaciaWhile inoculation together, can improve significantly white poplarP.tremuloidesWith face cream poplarP.angustifoliaTo the absorption of the nutrient such as N and P, thus the growth that improves root system. The researchs such as Garbaye think,P.involutusThe mycorhiza forming can improve significantlyQuercuspetraeaWithQ.roburThe drought-resistant ability of tree. In addition,P.involutusRadioactive element Cs-137 is also had to very strong absorption, and can effectively improve the anti-Cu of host2+、Cd2+And Pb2+Deng the ability of heavy metal pollution. The conversion transport of the stable and energy of mycorhiza to forest ecosystem plays positive facilitation, and it is the special parasitics of one that plant and microorganism reach high unity. A large amount of mycorhiza application study both at home and abroad shows, mycorhiza can obviously promote the growth of host plant, improves seedling quality, promotes the absorption of host to nitrogen, phosphorus, potassium, strengthens stress resistance of plant, improves host plant rhizospheric environment etc. Whether this beneficial effect of mycorhiza can be given full play to, and is decided by that can correctness and the mycorrhizal fungi of mycorrhizal fungi selection effectively infect host plant. For different seeds, Bole capacitance, Relative turgidity of bark, peroxidase activity, polyphenol oxidase activity and PAL activity index and trees disease resistance or resistance have close relationship.
