Problems solved by technology

Existing organic fertilizers generally have the following disadvantages: ① low nutrient content, slow fertilizer efficiency, and low seasonal utilization rate of nutrients in fertilizers; During the period when there is a large amount of organic fertilizers, organic fertilizers often cannot meet the nutrient needs of crops in time; ④The accumulation and use of traditional organic fertilizers is also very inconvenient, and organic waste such as human, livestock and poultry manure and garbage is a kind of dirty, rotten and smelly substances , which contains many pathogenic microorganisms, or mixed with some poisons, is an important source of pollution, and some manufacturers add coal soil and other substances to increase organic matter in order to make it meet the organic fertilizer standards of the Ministry of Agriculture, but the actual use effect is very poor. If it cannot absorb its nutrients, it will cause land compaction
In the past, sodium selenite was added to food for selenium supplementation. Its bioavailability is low, and the intake range (50-400ug / day) is narrow, and it is easy to cause poisoning due to excessive intake
Soil application of sodium selenite alone, due to soil fixation and a large loss, not only has low selenium availability, but also has poor safety and economic efficiency, so it cannot be used as a selenium supplement measure for agricultural product production

Abstract

The invention discloses a selenium-rich foliar fertilizer which is prepared from the following raw materials in parts by weight: 20-60 parts of urea, 10-50 parts of potassium dihydrogen phosphate, 10-30 parts of magnesium sulfate, 10-30 parts of potassium sulfate, 10-30 parts of sodium selenite, 10-30 parts of fulvic acid, 100-150 parts of pond sludge, 5-20 parts of rare earth, 0.01-0.5 part of sodium naphthaleneacetate, 5-10 parts of radix isatidis, 10-50 parts of compound auxiliary agent, 10-50 parts of medical stone extract, and 1-5 parts of selenium-rich yeast. The invention also discloses a preparation method of the selenium-rich foliar fertilizer. The selenium-rich foliar fertilizer is reasonable in proportioning of ingredients, is capable of effectively improving the fertilizer utilization rate of plants, promoting nutrient absorption of the plants, improving plant resistance and alleviating diseases, and also helps to improve the selenium content of agricultural products and meets absorption of the selenium element by the human body.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a selenium-enriched foliage fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizer is a kind of natural fertilizer that uses various organic substances in the countryside to accumulate on the spot or directly bury it. It is also called farm manure traditionally. Organic fertilizers can be roughly classified into the following four categories: ① manure and urine fertilizer, including human and animal manure and manure, poultry manure, sea guano and silkworm excrement, etc.; ③ Green manure, including cultivated green manure and wild green manure; ④ Miscellaneous fertilizers, including peat and humic acid fertilizers, oil meal, soil fertilizers, sea manure, agricultural salt, domestic sewage, industrial sewage, industrial waste residue, etc. Existing organic fertilizers generally have the following disadvantages: ① low nutrient content, sl...
