Brassica juncea fertilizer additive and preparation method thereof

Abstract

The invention discloses a brassica juncea fertilizer additive and a preparation method thereof. The brassica juncea fertilizer additive is prepared from acrylic acid, starch, N,N'-methylene bisacrylamide, rice hull powder, itaconic acid, chitosan oligosaccharide, areca dregs, sodium alginate, vitamin C, rape seed cakes, ascorbic acid, Caulis Fici Tikouae, EM microbial agent, industrial wastewater, agricultural rare earth, plant-derived raw materials and appropriate amount of water. Active ingredients in domestic wastes are obtained through fermentation extraction to play an important role in growth of crops, which is unreachable by chemical fertilizers. Organic acids fermented in fermentation can promote growth of vegetables such as brassica juncea with leaves and stems as major edible portions and make the leaves fresh, tender and fleshy, and yield increase and taste improvement are realized. Plant volatile components in the additive are conducive to avoidance of injurious insects and capable of preventing the injurious insects from gnawing the leaves, and pesticide spraying can be reduced, so that health is benefited.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a mustard fertilizer additive and a preparation method thereof. Background technique [0002] In nature, there are more than 100,000 known low-molecular-weight secondary metabolites synthesized and released by plants, of which volatile substances account for a large proportion, and most of them have a certain "smell". This kind of substance plays a very important role as a chemical signal of behavior hint between plants and between plants and insects. The control of pests and diseases through chemical pesticides not only damages the environment and wastes resources, but also improves the resistance of crop pests. Pesticides and serious pesticide residue problems affect human health and the management of pests is becoming more and more difficult. [0003] The volatile substances of plants belong to the secondary metabolites of plants. They are generally emitted fr...
