Method for promoting leguminous plant growth by using arbuscular mycorrhizal fungi and rhizobium

Abstract

The invention discloses a method for promoting leguminous plant growth by using arbuscular mycorrhizal fungi and rhizobium, which can improve the yield and quality of leguminous plant grassland without damaging a grassland ecosystem. In the method, by inoculating the arbuscular mycorrhizal fungi inoculant and rhizobium, nutrient absorption of leguminous plants can be promoted, the diversity and stability of communities can be improved, the space soil fertilizer utilization rate can be increased, leguminous nitrogen fixation can be promoted, host plants can be assisted in absorbing soil nutrients, soil can be loosened, soil hardening can be eliminated, soil structures can be improved, and the dosage of chemical fertilizers and pesticides can be reduced; loss of artificially applied chemicalnitrogen fertilizer is prevented, environmental pollution is reduced, and ecological safety is guaranteed; compared with chemical fertilizers, the utilization rate is higher, the acting time is long,the content of organic matter and nutrients in soil can be increased, fertility soil is improved, emission of greenhouse gas is reduced, and therefore the virtuous cycle of a grassland agricultural ecological system is promoted. The method is suitable for application and popularization in the technical field of pasture 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.
