Special compound fertilizer for broomcorn

Abstract

The invention discloses a special compound fertilizer for broomcorn. The special compound fertilizer is prepared from the following constituents in parts by weight: 50-65 parts of urea, 33-43 parts of ammonium sulfate, 20-25 parts of monoammonium phosphate, 27-37 parts of potassium sulfate, 15-22 parts of monopotassium phosphate, 7-11 parts of borax, 3-6 parts of zinc-amino acid chelate, 3-6 parts of attapulgite, 5-8 parts of compound sodium nitrophenolate, 5-8 parts of straw, 3-6 parts of bean pulp, 4-6 parts of vinasse, 1-5 parts of a biological bacterial agent and 1-5 parts of a plant growth regulator. The special compound fertilizer for the broomcorn, disclosed by the invention, can increase the yield of the broomcorn, lower dissolved rate of the fertilizer, increase the utilization rate of the fertilizer, improve the fertilizer efficiency, and promote circulating and long-acting absorption and utilization of the crop; the usage amount of the fertilizer can be lowered only in need of one-time application of the fertilizer; besides, the fertilizer can improve the soil properties, eliminate hardening and increase the moisture and fertility preservation capabilities; furthermore, the fertilizer can effectively prevent an eutrophication phenomenon.

Description

[0001] technical field [0002] The invention relates to special compound fertilizer for sorghum and belongs to the field of special compound fertilizer for crops. Background technique [0003] Sorghum, Poaceae; Sorghum, an annual herb. It is widely cultivated in China, with the most in Northeast China. Edible sorghum grains are used for food and wine making. Sugar sorghum stalks can be used to make syrup or raw food; brooms can be used to make brooms or cooking brooms; young leaves can be used as silage in the shade, or can be used as feed after drying; soothe the nerves. Belongs to economic crops. [0004] Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. Although most compound fertilizers must be multivariate, they still cannot completely replace organic f...

Problems solved by technology

However, excessive application of chemical fertilizers will cause harm: 1. Deterioration of soil properties

Large amounts of single-element chemical fertilizers are used in farmland, and their nutrients cannot be effectively absorbed and utilized by crops. Some chemical substances such as nitrogen, phosphorus, and potassium are easily consolidated by the soil, forming various chemical salts, and accumulating in the soil, resulting in imbalanced soil nutrient structure. The physical properties deteriorate, and the harmful metals and harmful bacteria in some plots exceed the standard, leading to the deterioration of soil properties

2. Lead to a decline in product quality

Partial application of certain chemical fertilizers leads to malnutrition of crops, hinders the transformation and synthesis of some substances in the body, and reduces the quality of products. For example, the current melons and fruits do not taste sweet, and vegetables do not taste delicious, and they are easy to rot and cannot be stored.
