Organic leaf surface fertilizer rich in organic selenium and vitamins and preparation method for organic leaf surface fertilizer

Abstract

The invention discloses an organic leaf surface fertilizer rich in organic selenium and vitamins and a preparation method for the organic leaf surface fertilizer. The organic leaf surface fertilizer rich in the organic selenium and the vitamins comprises the raw materials in parts by weight: 40-60 parts of selenium-enriched bombyx mori, 40-60 parts of selenium-enriched plant waste, 40-60 parts of selenium-enriched edible mushroom waste, 40-60 parts of sodium selenite, 20-30 parts of vitamins and 1-10 parts of a composite fungicide. The selenium-enriched bombyx mori, the selenium-enriched plant waste and the selenium-enriched edible mushroom waste of the fertilizer can supply selenium elements and also supply animal proteins, plant proteins and microorganism proteins and are fermented by composite bacteria to polypeptide combined with the selenium elements. Therefore, the fertilizer can be used for supplying enough organic selenium and beneficial substances such as microorganisms and probiotics to the growth of crops; a large amount of waste is turned into treasures, so that social and natural resources are saved, the environment is protected, and cyclic economy is realized.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a foliar organic fertilizer rich in organic selenium and vitamins and a preparation method thereof. Background technique [0002] At present, in terms of crop planting in my country, most of them still use chemical fertilizers. Although they have a certain effect on increasing production and income, long-term application will cause many disadvantages: [0003] 1. Destroy the soil, resulting in a decrease in soil organic matter content, an imbalance in the proportion of various nutrients, soil acidification and compaction, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in poor water retention, fertilizer retention, and air permeability, making it difficult to meet the needs of crops. actual growth needs; [0004] 2. Crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year,...

Problems solved by technology

[0003] 1. Destroy the soil, resulting in a decrease in soil organic matter content, an imbalance in the proportion of various nutrients, soil acidification and compaction, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in poor water retention, fertilizer retention, and air permeability, making it difficult to meet the needs of crops. actual growth needs;

[0004] 2. Crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year, otherwise, the crops will grow slowly, and the pests and diseases will be serious, resulting in reduced production;

[0005] 3. The agricultural ecological environment is deteriorating. After chemical fertilizers are applied to the farmland, the actual utilization rate is only 30% on average. Most of them flow into rivers and lakes with farmland drainage or remain in the soil, plants and crops, which not only brings environmental pollution but also endangers the safety of human beings and lives. and health, which are obstacles to sustainable agricultural development;

[0007] The above situations can be improved by applying organic fertilizers. However, there are many varieties of biological fertilizers, microbial fertilizers, biological phosphate fertilizers, and biological potassium fertilizers in China. Livestock manure is used for processing, and the application amount is very small, which cannot be used as the main fertilization, and the effect is single, and the price is high; in addition, with the improvement of people's living standards, selenium-enriched rice, selenium-enriched tea and other selenium-enriched agricultural products are also becoming more and more popular. more popular
