Special polymicro liquid nitrogen leaf fertilizer for vegetable

Abstract

The invention discloses a special polymicro liquid nitrogen leaf fertilizer for a vegetable. The leaf fertilizer comprises liquid nitrogen, urea, boron amino acid raw powder and EDTAZn (Zinc Sodium Ethylenediamine Tetraacetate), wherein the content of N in liquid nitrogen is not less than 32%, the content of in the urea is not less than 46%, the content of B in boron is not less than 20%, the content of amino acid in the amino acid raw powder is not less than 40%, the Zn content in the EDTAZn is not less than 14%, and the weight percentages of all the ingredients are as follows: 40% of liquid nitrogen, 22% of urea, 4% of boron, 25% of amino acid raw powder, and 9% of EDTAZn. The leaf fertilizer disclosed by the invention has the following beneficial effects that the fertilizer is practical, low in production cost, convenient to use, efficient, nutritious, capable of regulating and increasing yield, and is good in quality; nutrition can be absorbed quickly to promote the development of a root system and enhance photosynthesis and chlorophyll content of a leaf after the fertilizer is sprayed; the sprayed plant is dark green in leaf color, strong in growth, reduced in phenomena of fallen leaf, fallen flower and fallen fruit, and increased in resilience and disease resistance so that the purpose of increasing yield is achieved.

Description

technical field [0001] The invention relates to a vegetable foliage fertilizer, in particular to a special foliage fertilizer for vegetables with a lot of liquid nitrogen. Background technique [0002] At present, in the process of planting vegetables, people generally use two kinds of fertilizers: farmyard manure or chemical fertilizer. While these two kinds of fertilizers have their own advantages, they also have certain deficiencies and defects. [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 and easy to cause flooding and other phenomena; 4. The oxygen co...

Problems solved by technology

[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

[0005] The current chemical fertilizers are used in the growth process of vegetables, the nutrients obtained by vegetables are limited, the root system of vegetables is underdeveloped, the plants are not strong, and the yield is low

[0006] In addition, some existing fertilizers do not take nitrogen for vegetable growth into consideration, which affects the yield of vegetables
