Insect-damage-resistant major element water-soluble fertilizer

Abstract

The invention discloses an insect-damage-resistant major element water-soluble fertilizer. The insect-damage-resistant major element water-soluble fertilizer is prepared from the following raw materials in parts by weight: 15 to 20 parts of urea, 30 to 45 parts of dipotassium phosphate, 25 to 30 parts of potassium sulphate, 5 to 8 parts of magnesium nitrate, 4 to 8 parts of fly ash silicon-calcium fertilizer 0.09 to 0.5 part of compound sodium nitrophenolate, 2 to 4 parts of amidosulfonic acid, 1 to 3 parts of humate, 2 to 4 parts of sodium tartrate, and 2 to 10 parts of polybasic chelate micro element fertilizer; the polybasic chelate micro element fertilizer is a micro element fertilizer processed by a polybasic composite chelating agent; the polybasic composite chelating agent is a composition of polypeptide and organic phosphate. The insect-damage-resistant major element water-soluble fertilizer is reasonable in compatibility, and is added with elements of magnesium, calcium and the like and various micro elements while providing three major elements of nitrogen, phosphorus and potassium for crops, so that nutrition supply is more comprehensive and balanced, influence of insect damage is reduced, meanwhile, a fertilizer effect is reinforced and yield is improved.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizers, in particular to an insect-resistant macroelement water-soluble fertilizer. Background technique [0002] In recent years, my country has vigorously developed water-saving agriculture and vigorously promoted water-saving facilities such as sprinkler irrigation and drip irrigation. Water-soluble fertilizers can be well applied to some agricultural facilities, which can meet the requirements of water-saving agriculture and realize the integration of water and fertilizer. Water-fertilizer integration technology is of great significance to the development of water-saving agriculture, because it can save 30-40% of water, and can improve the utilization rate of fertilizer, which can save 30-50% of fertilizer. With the vigorous development of my country's water-saving agriculture and the rapid development of commercial fertilizers, the development of water and fertilizer integration wi...

Problems solved by technology

[0003] Epidemic diseases and insect pests are important factors affecting the growth and yield of crops. At present, the commonly used method of eliminating insect pests is to use insecticides. Although insecticides can protect insect pests very well, they also bring environmental pollution. Excessive use will easily lead to resistance of pests. Medicinal properties
