Nanometer biological regulation and control method for improving growth, yield and quality of corn

Abstract

The invention discloses a nanometer biological regulation and control method for improving growth, yield and quality of corn, and belongs to the technical field of nano agricultural regulation and control. The method comprises the following steps: inoculating earthworms into root soil and applying a nano silicon dioxide solution; wherein the particle size of the silicon dioxide is 8-60 nm, the silicon dioxide solution is a nano silicon dioxide aqueous solution, and the concentration of the nano silicon dioxide aqueous solution is 10-100 mg/L; the earthworms comprise inner-deep habitat type earthworms, namely, Metaphire guillelmi, and surface-habitat type earthworms, namely, Eisenia foetida; the inoculation density of the earthworms is 1-4 earthworms per plant, and the application period is the emergence period of the corn. According to the method, the overground biomass, the underground biomass, the leaf silicon content, the root silicon content and the net photosynthesis of the corn in the seedling stage are effectively improved, and the yield per plant, the hundred-grain weight, the grain starch content and the soluble sugar content of the corn are finally improved.

Description

technical field [0001] The invention relates to a nano-biological control method for improving the growth, yield and quality of corn, and belongs to the technical field of nano-agricultural control. Background technique [0002] The existing methods to promote corn production are mainly achieved by increasing the application of chemical fertilizers or using a large amount of organic fertilizers, which have complex operating procedures and cumbersome applications, and cannot meet the urgent needs of ecological and environmental protection. [0003] Moreover, the soluble silicon slowly released from a large number of farmland soils in my country can no longer meet the silicon demand of crops (such as rice, corn and other silicon-loving plants), which seriously restricts the high and stable yield of farmland crops. In order to improve crop yield and stress resistance, the application of traditional silicate fertilizers has been continuously increased in agricultural production,...
