Vegetable foliar biological fertilizer and preparation method thereof

Abstract

The invention discloses a vegetable foliar biological fertilizer, which comprises the following components in percentage by weight: 15 to 20 percent of silk worm pupa amino acid, 40 to 60 percent of korean pine bark, 2 to 5 percent of bagasse, 8 to 15 percent of boromagnesite, 1 to 7 percent of shrimp and crab shells, 1 to 5 percent of animal waste internal organs (dried), 5 to 12 percent of kaolin and 1 to 3 percent (dry weight) of bacillus. Silk worm pupae are subjected to proteolysis and product of the proteolysis is purified to produce amino acid and the same amount of amino acid is mixed; bacillus fermentation liquor is obtained by fermentation; the bagasse, korean pine bark, boromagnesite, kaolin, shrimp and crab shells and animal waste internal organs are ground to form 38 to 50 micrometer powder respectively, the auxiliary materials are mixed in a ratio, the bacillus fermentation liquor is mixed with a powder mixture uniformly and the resulting mixture is dried at 40 to 50 DEGC; and the silk worm pupa amino acid is added in a weight ratio, and the mixture is mixed uniformly. The fertilizer is low in soil residual level and can promote crop yield increase, improve product quality and resist diseases and insect pests. Thus, the fertilizer is worthy to be promoted.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a foliage ecological fertilizer and a preparation method. Background technique [0002] At present, the current situation of the use of chemical fertilizers in my country is that the amount of use is large, but the effective utilization rate is low, resulting in a series of serious problems such as the destruction of soil structure, the reduction of natural biodiversity and the stability of ecosystems. [0003] Foliar fertilizer is absorbed through the leaves of plants. It has the characteristics of fast absorption, quick effect and convenient application. It is widely used in vegetables, tea, tobacco and various economic crops. Among them, nutrient-type foliar fertilizers contain a large amount of medium and trace elements needed for plant growth; hormone-based foliar fertilizers contain chemical substances that regulate plant growth and development, which can only promo...

AI Technical Summary

Problems solved by technology

Among them, nutrient-type foliar fertilizers contain a large amount of medium and trace elements needed for plant growth; hormone-based foliar fertilizers contain chemical substances that regulate plant growth and development, which can only promote the vegetative growth of crops, but cannot effectively regulate the vegetative growth of crops. The contradiction with reproductive growth is manifested in the increase of stems and leaves, but not the increase in yield, which cannot improve the quality of agricultural products, and the excessive use of hormones endangers the quality of agricultural products and thus endangers human health; the main function of biological foliar fertilizers is to stimulate crop growth and promote crop growth. Metabolism to prevent the occurrence of diseases and insect pests, however, biological components exist in a suspended state in the amino acid liquid phase, which affects the absorption of crops; compound foliar fertilizer is a combination of nutrient foliar fertilizer and hormone foliar fertilizer
