Improved composite potassium dihydrogen leaf fertilizer

Abstract

The invention discloses an improved composite potassium dihydrogen leaf fertilizer. The leaf fertilizer comprises monoammonium phosphate and potassium nitrate, wherein the content of N in the monoammonium phosphate is not less than 10%, the content of P2O5 in monoammonium phosphate is not less than 48%, the content of N in potassium nitrate is not less than 14%, the content of K2O in potassium nitrate is not less than 45%, the weight percentages of all the ingredients are as follows: 55-60% of monoammonium phosphate and 40-45% of potassium nitrate, effective nitrogen in the improved composite potassium dihydrogen leaf fertilizer is not less than 8%, the content of NH4<+1> is not less than 2.5%, the content of NO3<-1> is not less than 5.5%, effective phosphorus P2O5 is not less than 26% and effective potassium K20 is not less than 17%. The fertilizer disclosed by the invention has the following beneficial effects that the fertilizer is practical and low in production cost; nutrition can be absorbed quickly to promote the development of a root system after the fertilizer is sprayed; and the defect that a monopotassium phosphate leaf fertilizer does not contain N element is made up so that the characteristic of comprehensive nutrition of nitrogen, phosphorus and potassium of the fertilizer is fully developed to cause a plant to grow lusher and stronger to reach the purpose of increasing yield.

Description

technical field [0001] The invention relates to a foliar fertilizer, in particular to a compound improved potassium dihydrogen foliar fertilizer. Background technique [0002] Potassium dihydrogen phosphate is a good variety used as a foliar fertilizer. Potassium dihydrogen phosphate contains two elements, phosphorus and potassium (of which P 2 o 5 ≥52%, K 2 O≥34%). However, lack of nitrogen, as a foliar fertilizer, a large number of elements are incomplete, which will have a certain impact on plant growth. [0003] The shortcomings of farmyard manure are mainly reflected in: 1. The composition is complex, the fertilizer effect changes greatly, and it is difficult to grasp the accurate amount of fertilizer; 2. The decomposition is slow and the fertilizer effect is late; 3. The amount is large, the operation is heavy, and the content of organic matter in the water is increased. Applying after fermentation will also bring in a large amount of slag, causing water pollution ...

Problems solved by technology

However, there is a lack of nitrogen. As a foliar fertilizer, the nutrition of a large number of elements is incomplete, which will have a certain impact on plant growth.

[0003] The deficiencies of farm manure are mainly reflected in: 1. The composition is complex, the fertilizer effect changes greatly, and it is difficult to grasp the accurate amount of fertilizer; 2. The decomposition is slow and the fertilizer effect is late; Applying after fermentation will also bring in a large amount of surface slag, causing water pollution and easy to cause flooding and other phenomena; 4. The oxygen consumption is large. According to statistics, it takes 3.4-3.8 tons of oxygen to decompose 1 ton of manure

[0004] The deficiencies of chemical fertilizers are mainly reflected in: 1. The composition is single and the nutrition is not comprehensive. It needs to be used in combination with several kinds of chemical fertilizers or mixed with organic fertilizers, and the cost of use is high; Pollution of water quality also increases the cost of use; 3. Since the fertility of inorganic fertilizers is not long-lasting, only a small amount of fertilizers can be used multiple times and depending on the water, which is troublesome to use
