Study On Mycorrhizal Inoculation Technology In The Breeding Of Fast-growing Pinus Sylvestris Var. Mongolica And Pinus Tabulaeformis Seedlings Light Matrix

Pinus sylvestris var. mongolica and Pinus tabulaeformis are genus of evergreen trees. They have strong ability to adapt to the harsh climate and poor soil environment, and strong drought-resistant, high temperature and low temperature capabilities, and salinity, they are important "Three North" region planting trees. Pinus sylvestris and nutrition package nursery light matrix technology is that in the temperature, humidity and light conditions are controllable intelligent greenhouse, achieves economies of scale and standardized production of seedlings. However, nutrition pack light matrix of seedlings has the low survival rate in the northwest shed harsh environment. Mycorrhizal plant roots can effectively increase the absorption area, enhance root absorption of water and nutrients needed by plants and can release hormones, promote plant growth,to improve plant resistance to harsh environment, they are also very significant. The experiment will combine light matrix Pinus sylvestris and Pinus tabulaeformis seedling technology with artificial nutrition package ectomycorrhizal fungi inoculation technology to explore a rapid breeding of mycorrhizal Pinus sylvestris and Pinus tabulaeformis seedlings light path matrix nutrition package. The main experiment results are the following conclusions:1. In modern intelligent greenhouse conditions, the application of nutrition package and soaking liquid inoculants nutrition package spraying methods can not pack light matrix of Pinus sylvestris and Pinus tabulaeformis seedlings inoculated with mycorrhizal fungi nutrition.2. For annual Pinus sylvestris and Pinus tabulaeformis seedlings dipping light matrix liquid agents in the treatment and transplanted into peat imports, domestic peat, sphagnum moss and ordinary soil, inoculated with mycorrhizal fungi infection rates are more than80%, indicating effective vaccination.3. Four different matrix graft inoculation treatment and did not see ported to increase rate of imports growth index and sphagnum peat matrix light matrix Pinus sylvestris and Pinus tabulaeformis seedlings largest, both basically the same effect, followed by was inoculated into seedlings domestic peat soil, and finally to the normal soil inoculated seedlings. 4.For the same graft matrix, the inoculation inoculation treatment than non-Pinus sylvestris and Pinus tabulaeformis and light matrix seedling growth nutrient package, including height, diameter, biomass, and other indicators have improved to varying degrees, indicating that bacteria butt seedling root growth has played a certain role.5.Transplanting under the same conditions, Pinus tabulaeformis seedlings inoculated with mycorrhizal infection rate of about5%in the Pinus sylvestris seedlings, pine seedlings corresponding increase rate is higher than the growth indicators pine seedlings, indicating porcini liquid milk brown ring in contrast bacteria more suitable for Pinus sylvestris seedlings inoculated.6. Mycorrhizal agents on transplanted into ordinary soil matrix light Pinus sylvestris and Pinus tabulaeformis seedlings grown nutrition package is higher than the contribution of migration to import nutrient soil, the contribution to the growth of domestic and sphagnum peat seedlings, and transplanted to import nutritional soil, made of sphagnum peat and light Pinus tabulaeformis seedling growth matrix significantly improve nutrition package is mainly due to the superiority of transplantation matrix plays a major role.
