Organic fertilizer capable of improving stress resistance of plants and preparation method of organic fertilizer

Abstract

The invention discloses an organic fertilizer capable of improving stress resistance of plants. The organic fertilizer comprises the following raw materials in parts by weight: 40-50 parts of corns, 23-35 parts of soybean meal, 16-26 parts of urea, 10-15 parts of wheat bran, 6-8 parts of cake-shaped rape seed dregs, 4-5 parts of boron humate, 4-5 parts of EM microbial agent, 4-5 parts of ammonium sulfate, 3-6 parts of fulvic acid, 3-4 parts of medical stone, 3-4 parts of zinc humate, 3-4 parts of manganese humate, 2-3 parts of abscisic acid, 2-3 parts of ethephon and an appropriate amount of water. The organic fertilizer disclosed by the invention has various nutritional components and contains not only a lot of elements and trace elements required for the growth and development of various crops and but also contain microbial communities and a lot of organic substances having a special nutritional effect on crop roots; by applying the organic fertilizer, the resistance to pests and diseases and the lodging resistance of crops can be enhanced, the heat-retaining capacity and drought tolerance of crops are improved and safety and no pollution to human and environment are achieved; and by adding abscisic acid, the cold tolerance, frost resistance, drought tolerance and salt resistance of plants can be enhanced and the purpose that the yields of food crops and fruit trees is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer for improving stress resistance of plants and a preparation method thereof. Background technique [0002] Although traditional inorganic chemical fertilizers have high nutrient content and rapid fertilizer effect, their fertilizer effect is strong but not long-lasting, and the effect of improving soil is not great, and even has side effects of destroying soil properties. The large-scale use of inorganic chemical fertilizers in agricultural production will bring such as Various problems such as quality decline, soil compaction, and water pollution. With the improvement of people's living standards, residents' demand for safe, hygienic and pollution-free organic and green food continues to increase. The majority of farmers urgently need to use organic fertilizers to improve the market competitiveness of agricultural products. Organic fertilizers are rich ...
