However, long-term and large-scale application of chemical fertilizers often leads to environmental pollution
Due to the long-term application of inorganic salt compound fertilizers, the soil is acidic and the soil is hardened and cannot be used for crop growth; most organic fertilizers are made of manure, alcohol residue, sugar residue, etc. Although it has comprehensive nutrition, it can improve soil. environment, but raw materials often contain heavy metals and harmful bacteria

Abstract
The invention discloses special composite fertilizer for soybeans. The special composite fertilizer is prepared from the following raw materials in parts by weight: 20 to 26 parts of urea, 40 to 50 parts of diammonium phosphate, 30 to 40 parts of potassium chloride, 1 to 2 parts of borax, 1 to 2 parts of sodium selenite, 1 to 2 parts of medium trace elements, 1 to 2 parts of amino acid, 8 to 12 parts of decomposed coal, 5 to 9 parts of distiller slag, 30 to 40 parts of matured chicken dung, and 0.3 to 0.5 part of beneficial microbial agent. The special composite fertilizer for the soybeans is reasonable in ingredient proportioning, capable of promoting the balanced and reasonable absorption of the soybeans to various nutrients by virtue of the synergy of the nutrients, suitable for the fertilizer demand principle of the growth and development of the soybeans, and capable of remarkably improving the yield and quality of the soybeans.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special compound fertilizer for soybeans. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. Inorganic fertilizers are mineral fertilizers, also called chemical fertilizers, or chemical fertilizers for short. It has the characteristics of simple ingredients, high content of active ingredients, easily soluble in water, fast decomposition, and easy absorption by roots, so it is called "quick-acting fertilizer". Inorganic fertilizers and chemical fertilizers are widely used by farmers because of their high nutrient content and rapid fertilizer efficiency. However, long-term and large-scale application of chemical fertilizers often leads to environmental pollution. Due to the long-term application of inorganic salt compound fertilizers, the soil is a...
