Amino acid water soluble fertilizer for cotton crops and preparation method thereof

Abstract

The invention discloses amino acid water soluble fertilizer for cotton crops. The amino acid water soluble fertilizer is prepared from 70-78wt% of an amino acid mother liquor, 20-30wt% of citric acid, 15-20wt% of zinc sulfate, 15-20wt% of ferrous sulfate, 15-20wt% of magnesium sulfate, 0.2-0.5wt% of sodium molybdate, 0.2-0.5wt% of composite uronic acid, 15-20wt% of ammonium molybdate tetrahydrate, 15-20wt% of potassium dihydrogen phosphate, 15-20wt% of manganese sulfate, 15-20wt% of boric acid, 15-40wt% of urea, 5-10wt% of disodium octaborate tetrahydrate, 15-20wt% of a composite amino acid solution comprising free amino acids, and composite inocula. The amino acid water soluble fertilizer has substantial effects of rooting, seeding promoting, straw strengthening, stress resistance, yield increasing and quality improvement, has high contents of a plurality of agricultural product fermentation degradation materials and active amino acids, has good crop absorption efficiency, can promote rooting and flowering and improve flower color and has good stress resistance.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an amino acid-containing water-soluble fertilizer for cotton crops and a preparation method. Background technique [0002] At present, cotton is the world's largest food crop. my country is one of the world's largest cotton-growing countries, with abundant cotton resources and a wide variety of fine varieties. Fertilizer is an indispensable nutrient in the growth process of cotton crops. Scientific fertilization can improve the growth environment of cotton crops and improve crop yield and quality. However, due to the long-term, large or excessive application of single chemical fertilizers in the process of planting cotton, the physical and chemical properties of the soil and the beneficial bacteria in the soil have been damaged to varying degrees, the utilization rate of crop fertilizers is low, and many nutrients are lost. The long-standing farming concept has ...

Problems solved by technology

However, due to the long-term, large or excessive application of single chemical fertilizers in the process of planting cotton, the physical and chemical properties of the soil and the beneficial bacteria in the soil have been damaged to varying degrees, the utilization rate of crop fertilizers is low, and many nutrients are lost. The long-standing farming concept has paid special attention to the application of macronutrients, and insufficient understanding of the importance of micronutrients, resulting in a serious imbalance in the ratio of macronutrients to microelements in the soil, increased difficulty in increasing crop production, and overall decline in crop quality, etc. problem, the role of medium and trace elements in agricultural production has become increasingly prominent

As a result, cotton fertilizer damage and diseases are frequent in our country, and the yield and quality of cotton are seriously reduced.
