Macroelement water soluble fertilizer having effect of improving crop growth environment and application thereof

Abstract

The invention relates to the field of fertilizers, and in particular, relates to a macroelement water soluble fertilizer having an effect of improving a crop growth environment. The macroelement water soluble fertilizer comprises the following components in parts by weight: 50-100 parts of potassium fulvate, 1-15 parts of alga oligosaccharides, 1-15 parts of chitosan oligosaccharide, 100-300 parts of potassium nitrate, 300-500 parts of potassium dihydrogen phosphate, 100-300 parts of ammonium nitrate, 200-500 parts of urea, 10-30 parts of magnesium sulfate monohydrate, 5-25 parts of boric acid, 1-15 parts of EDTA chelated manganese, 1-15 parts of EDTA chelated iron, 1-15 parts of EDTA chelated copper, and 1-15 parts of EDTA chelated zinc. The fertilizer provided by the invention has comprehensive nutrients, has the effect of improving the soil micro ecological environment and soil property components, and has the advantages of rich content of medium-trace elements, high crop-absorbed utilization efficiency, high fertilizer efficiency and excellent water-saving effect.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a macroelement water-soluble fertilizer with the effect of improving the growth environment of crops. Background technique [0002] Diseases during crop growth are one of the important reasons affecting crop yield, and most of the pathogenic bacteria are fungi, especially most soil-borne diseases are difficult to control. On the other hand, long-term unreasonable application of chemical fertilizers and irrigation with sewage will cause soil salinity. Waterlogging, soil acidification, barrenness and a series of problems, and the quality of the soil environment directly affects the yield and quality of crops. Water conservation has always been valued. Water-soluble fertilizers can be used to carry fertilizers with water, and the integration of water and fertilizers is more conducive to water conservation. Support sustainable development. [0003] Seaweed oligosaccharides can change th...

Problems solved by technology

[0004] Patent CN102633551B discloses a method for producing macroelement water-soluble fertilizer from agricultural fertilizers. The method uses agricultural raw materials to produce macroelement water-soluble fertilizer, which contains a large amount of elements required by crops. Patent CN104961527A discloses a macroelement water-soluble fertilizer and its preparation method. Contains a large amount of elements and medium and trace elements required by crops, has long fertilizer effect and good sustainability, and is beneficial to crop growth. However, the existing technology focuses on crop growth, and rarely improves crop resistance while taking into account the effect of improving the soil environment, which is not conducive to soil.
