Water-soluble solid organic complexed microelement fertilizer used for improving secondary salinization land, and production method thereof

Abstract

The invention discloses a water-soluble solid organic complexed microelement fertilizer used for improving secondary salinization land. The water-soluble solid organic complexed microelement fertilizer comprises, by mass, 1000-1500 parts of iron EDDHA, 1000-1300 parts of sodium alginate, 1000-1500 parts of zinc EDTA, 800-1200 parts of phosphorus ore powder, 1200-1800 parts of liquid complexed organic boron, 35-50 parts of potassium hydroxide, 10-20 parts of citric acid, 50-80 parts of magnesium sulfate, 60-90 parts of a compound enzyme preparation and 30-60 parts of ferment bacteria. The water-soluble solid organic complexed microelement fertilizer has the advantages of good water solubility, soil improvement, supplementation of trace elements, balancing of crop nutrients, fertilizer effect enhancement, growth promotion, good adversity resistance, and improvement of the yield and the quality of crops, can well cooperate with other compound fertilizers, and especially can be conveniently flexibly blended according to the practical needs of land and the growth of crops in order to realize great use convenience.

Description

technical field [0001] The invention relates to a water-soluble solid organic complex micro-fertilizer for improving secondary saline-alkali land and a production method thereof. Background technique [0002] Soil secondary salinization, also known as "secondary salinization", refers to the process of turning good cultivated land into "salinization" due to unreasonable cultivation and irrigation measures and changes in vegetation. It mainly occurs in my country's North China Plain, Songliao Plain, Hetao Plain, Weihe Plain and other places. There are three main reasons for the formation of secondary salinization: First, the coconut bran drainage system in the farmland is not smooth, and a large amount of coconut bran irrigation has raised the level of underground coconut bran, increasing the speed of underground coconut bran moving upward through soil capillaries and the underground coconut bran. The evaporation of bran increases the accumulation of salt in the underground c...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the existing defects and provide a water-soluble solid organic complex micro-fertilizer for improving secondary saline-alkali land, which can overcome the antagonism between trace elements in existing fertilizers and the effect of phosphoric acid. When salt exists, it precipitates, the fertilizer is easily lost, and the effective nutrients in the fertilizer cannot be used to the greatest extent.
