Chelated powdery water-soluble leaf fertilizer containing surfactant and preparation method of leaf fertilizer

Abstract

The invention relates to a chelated powdery water-soluble leaf fertilizer containing a surfactant, which is applied in the field of agriculture and forestry. The leaf fertilizer consists of the following materials by weight percent: 25-45% of potassium sulfate, 15-55% of ammonium sulfate, 10-20% of monoammonium phosphate, 1-22% of calcium chloride, 0.1-0.7% of copper sulfate, 0.1-0.7% of zinc sulfate, 0.5-1% of borax, 0.1-1.0% 0f ferrous sulfate, 0.1-0.7% of manganese sulfate, 0.1-0.7% of ammonium molybdate, 1-12% of surfactant, 0.1-0.5% of EDTA (ethylene diamine tetraacetic acid), 0.1-3% of sodium citrate, 0.5-5% of sugar alcohol, 0.1-5% of monoethanol diamine and 0.1-1.0% of triethanolamine. The chelated powdery water-soluble leaf fertilizer is prepared by the steps of smashing, liquefying, chelating, drying and smashing the materials in a certain proportion, thus preparing the chelated powdery water-soluble fertilizer. By the reasonable proportioning of N, P and K materials and trace elements, the chelated powdery water-soluble fertilizer resistant to hard water and not prone to deliquescing and agglomeration is prepared; and the chelated powdery water-soluble leaf fertilizer has the characteristics of improving the comprehensive nutrition for the growth of crops, and being high in fertilizer efficiency, practical, wild in application and the like.

Description

technical field [0001] The invention relates to an agricultural water-soluble fertilizer, in particular to a multi-component chelating powdery water-soluble fertilizer containing a surfactant. Background technique [0002] The commercialization of foliar fertilizers in China began in the 1980s. After more than 20 years of development, the production of foliar fertilizers has been greatly developed, from a single component to a compound component, from a large number of nutrients to Trace elements and beneficial elements, from inorganic nutrients to organic nutrients, from mineral nutrients to the addition of surfactants, increase leaf surface development, and the absorption effect is the best. [0003] In recent years, both at home and abroad have attached great importance to the production and application of foliar fertilizers. China has also developed rapidly in the production and application of foliar fertilizers. The names of foliar fertilizers are diverse. The products...

AI Technical Summary

Problems solved by technology

Foliar fertilizer solves the following problems: when the crops are inconvenient to fertilize the roots, such as in the later stage of crop growth, the root vitality declines and the fertilizer absorption capacity decreases; or when the soil environment is unfavorable to crop growth, such as excessive water, drought, and too acidic soil , over-alkali, causing the root absorption of crops to be blocked, and crops need to recover quickly. If the method of root application cannot meet the needs of crops in time, only foliar spraying can quickly replenish nutrients and meet the needs of crop growth and development.
