Selenium-rich brassinolide-containing fertilizer for vegetables

Abstract

The invention relates to a selenium-rich brassinolide-containing fertilizer for vegetables, wherein the selenium-rich brassinolide-containing fertilizer comprises, by weight, 30-60 parts of sodium selenite, 30-50 parts of biochar, 1-15 parts of EDTA chelated iron, 5-30 parts of mashed garlic, 15-20 parts of willow bark, 10-20 parts of lees, 10-20 parts of livestock and poultry manure, 10-20 partsof mixed bacteria powder, 10-20 parts of acrylic acid, 10-30 parts of diammonium hydrogen phosphate, 10-40 parts of potassium dihydrogen phosphate, 15-30 parts of weathered coal, 15-20 parts of peat soil, 20-30 parts of coconut shell fiber powder, and 30-45 parts of brassinolide. According to the present invention, the prepared compound fertilizer contains a variety of trace elements, has high value, cannot produce drug residues, and can achieve the sustainable development of agriculture.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a vegetable selenium-rich fertilizer containing brassinosteroid lactone. Background technique [0002] In agricultural production, inorganic fertilizers occupy most of the market. However, inorganic fertilizers have great deficiencies and defects, mainly in the following aspects: [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 s...

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 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 human beings and lives. Safety and health, which have become obstacles to the sustainable development of agriculture
