Method for promoting growth of legumes using arbuscular mycorrhizal fungi and rhizobia

Abstract

The invention discloses a method for promoting the growth of leguminous plants by using arbuscular mycorrhizal fungi and rhizobia, which can improve the output and quality of legume grassland without damaging the grassland ecosystem. By inoculating arbuscular mycorrhizal fungal agents and rhizobia, this method can promote the nutrient absorption of legume plants, improve the diversity and stability of the community, improve the utilization rate of space soil fertilizer, promote nitrogen fixation of legumes, and assist host plants to absorb soil Nutrients can loosen the soil, eliminate soil compaction, improve soil structure, reduce the amount of chemical fertilizers and pesticides, prevent the loss of artificial nitrogen fertilizers, reduce environmental pollution, and protect ecological safety. Compared with chemical fertilizers, they have higher utilization rates and longer action times. And it can increase the organic matter and nutrient content of the soil, improve and fertilize the soil, reduce the emission of greenhouse gases, and thus promote the virtuous cycle of the grassland agricultural ecosystem. It is suitable for popularization and application in the technical field of forage planting.

Description

technical field [0001] The invention relates to the technical field of forage planting, in particular to a method for promoting the growth of leguminous plants by using arbuscular mycorrhizal fungi and rhizobia. Background technique [0002] In recent years, due to various natural disasters, serious overloading of grassland livestock capacity, excessive reclamation and excavation, tourism and other human interference problems have increased, the grassland ecosystem has been destroyed, seriously affecting the development of grassland animal husbandry, and with the current world economy With the rapid development of China's rapid development, people's demand for animal food such as meat and dairy products continues to expand, which puts forward greater requirements for grassland productivity. Facing the bottleneck problem of severe shortage of high-quality forage materials, and at the same time curbing the ecological security problems such as the serious decline of ecological ...

AI Technical Summary

Problems solved by technology

[0003] Existing methods for promoting the growth of leguminous plants are mainly realized through fertilization, but the method of fertilizing to promote the growth of leguminous grasslands has high production costs and requires a lot of manpower and material resources. Too little fertilization has no significant effect on grassland production increase, and excessive Excessive fertilization will cause soil acidification and soil compaction, and a large amount of fertilizer enrichment will flow into nearby water bodies with rainfall, causing environmental damage and disrupting the ecosystem.
