Efficient multi-element compound fertilizer

Abstract

The invention discloses an efficient multi-element compound fertilizer, which consists of hexanoic acid 2-(diethylamino) ethyl ester, polypeptide chelated potassium, polypeptide L-aspartate potassium, urea, potassium chloride, diammonium phosphate, calcium superphosphate, potassium dihydrogen phosphate, calcium-magnesium phosphate fertilizer, ammonium chloride, thiamine, zinc chloride, borax, ferrous sulphate, copper sulphate, manganese sulfate, sodium molybdate, cobalt chloride and silicon-manganese phosphate fertilizer. The efficient multi-element compound fertilizer has the advantages of promoting the growth of crops, improving the disease resistance of the crops, resisting falling, insect pests and frozen injury, improving the fertilizer effect, improving the soil, accelerating the growth of branches and leaves, reinforcing the photosynthesis, accelerating the growth of roots, enhancing the drought resistant capacity, improving the yield of the crops and improving the quality of fruits. The yield of grain crops is averagely increased by more than 26 percent, the yield of economic crops is averagely increased by more than 33 percent, and the yield of vegetable crops is averagely increased by more than 42 percent.

Description

technical field [0001] The invention belongs to a chemical fertilizer for crops, in particular to a high-efficiency multi-element compound fertilizer. Background technique [0002] At present, there are countless varieties of chemical fertilizers on the market. In the 1960s and 1970s, chemically synthesized fertilizers based on ammonia, urea, and diammonium phosphate were used as the main fertilizers to increase crop production. Due to long-term use, the acid-base balance of the land was out of balance, resulting in land compaction. At the same time, it also caused the lack of trace elements in the land. Ever since, in the 1980s and 1990s, special fertilizers for various crops appeared. Such as: special fertilizer for wheat, corn, cotton, soybean, peanut and other crops. Due to the long-term use of a large number of single special fertilizers, the land lacks one or more trace elements. Since the beginning of two thousand years, compound fertilizers, long-acting multi-ele...

And due to the long-term use of a single special fertilizer in large quantities, the land lacks one or several trace elements

Since the beginning of two thousand years, compound fertilizers, long-acting multi-element compound fertilizers, growth promoters, buffer fertilizers, etc., such as the application number 99115674.9 published by the National Patent Office in July 2001, although they contain a variety of trace elements, are beneficial to crops. The growth has a certain effect, but the effect is not obvious, and the fertilizer effect time is short, which to a certain extent restricts the improvement of crop yield and quality in the later stage. These fertilizers cannot meet the needs of crop growth, making crops poor disease resistance, many pests, and not resistant to freezing damage , not resistant to lodging, affecting the yield and quality of crops, and causing economic losses to farmers
