Experimental Production Of Complex Ectomycorrhizal Fungal And Bacterial Fertilizers And Its Effects On Chinese Pine Seedlings

Mycorrhizal Biological Technique attracts the most attention in the field of research and Sustainable development of new Biological Technique based on microbial fertilizer. The Mycorrhizal Biological Technique is an important Technical Way of vegetation restoration in the west arid zone of China. The industrial production of mycorrhizal inoculum are paid more attention in the Mycorrhizal Biological Technique. This paper mainly studied Optimization of Production Process for Complex Ectomycorrhizal Fungal and Bacterial Fertilizers and its Effects on Chinese pine seedings.The main points of research can be summarized as follows:1. Technological optimization of making mycorrhizal inoculum were studied using preponderant ectomycorrhizal Fungi Suillus luteus in the west. The structure characteristics and physical properties of capsule and the mycelium viability and the amount of hyphae were assessed. The results showed that turf and Cocopress were the best material. The best immobilization agent density was between 1% and 7%. Immobilization time was ten minute.2. Complex Ectomycorrhizal Fungal and Bacterial Fertilizers using Suillus luteus and Azotobacter chroococcum as active component were made in the optimization technology condition. Its quality index includes that mycelium germinated in Over 95% of capsule,The number of living bacteria in one capsule was 26×108,infectious mixed bacteria rate was less than 5%,The period of validity was 4 months, the pH value was 6.5, water ratio was 85%.3. The Effect Test of Complex Ectomycorrhizal Fungal and Bacterial Fertilizers on Chinese pine seeding showed that the mycorrhizal infection rate was 52.23%, and The seedling height, ground diameter, root/shoot rate,biomass and the number of lateral roots of mycorrhizal seedlings were enhanced by 14.85%,15.98%,27.75%,28.00% and 33.09% respectively in contrast to the non inoculation treatment,and were enhanced by 2.23%,3.38%,4.32%,6.34% and 2.84% respectively in contrast to the mycorrhizal inoculation treatment. The number of living bacteria in nursing media was 107/g.
