Application of AM (arbuscularmycorrhizal) fungi to increasing crop yields and method for applying AM fungi to increasing crop yields

Abstract

The invention discloses a method for applying AM (arbuscularmycorrhizal) fungi to increasing crop yields, and belongs to the field of agricultural microbiology application technologies. The method includes 1), sowing crop seeds into cultivation pots; 2), inoculating the AM fungi on the surfaces of the crop seeds; 3), transplanting crop seedlings infected by the AM fungi to experimental fields 10-15 days after seedlings of the sown seeds emerge; 4), applying compound fertilizers to the root of each seedling 15-20 days after the seedlings are transplanted to the experimental fields, paying attention to preserving soil moisture thereafter and properly performing ridging; 5), harvesting crops after the crops are ripe. The method has the advantages that symbionts are set up among the AM fungi and root systems of the crops, so that absorption areas of the root systems of the crops can be expanded, inorganic and organic fertilizers in soil can be sufficiently utilized, loss of the fertilizers and environmental pollution can be reduced, operation is facilitated, the agricultural cost is low, harden soil can be rehabilitated, the crop yields can be obviously increased as known from contrast experiments, and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural microorganism application, and in particular relates to the application and application method of AM fungi in improving crop yield. Background technique [0002] Fertilizer application is one of the effective ways to increase plant yield. However, plants cannot fully absorb and utilize most of the organic and inorganic fertilizers in the soil. Most of the farmlands have excessive fertilization. If things go on like this, the soil fertilizer efficiency will decrease and the fertilizer utilization rate will decrease. reduced situation. [0003] With the development of society, people pay more and more attention to ecological agriculture and green food. The mycorrhizal mycelium in the soil can form a mutualistic symbiont with the vegetative root system of higher plants. In the soil lacking minerals, nitrogen and phosphorus, etc., it can distribute the huge extra-root mycelium network to a wider...
