Special compounded fertilizer for sugar canes

Abstract

The invention discloses a special compounded fertilizer for sugar canes. The special compounded fertilizer is prepared from the following raw materials in parts by weight: 46-50 parts of polypeptide urea, 10-15 parts of diammonium phosphate, 20-28 parts of potassium chloride, 1-2 parts of magnesium sulfate, 1-2 parts of zinc sulfate, 1-2 parts of borax, 1-2 parts of compound amino acid, 1-3 parts of humic acid, 1-3 parts of chitosan, 10-18 parts of attapulgite, 20-24 parts of rice chaff, 15-20 parts of decomposed cattle manure, 5-10 parts of plant ash, 3-5 parts of soybean curd residue and 0.3-0.5 part of EM microbial agent. According to the special compounded fertilizer for the sugar canes, provided by the invention, the matching of ingredients is reasonable; and by a synergistic effect among all nutritional ingredients, the balanced and reasonable absorption of the sugar canes to the nutritional ingredients can be promoted, the fertilizer requirement law of the growth and development of the sugar canes is adapted, and thus the yield and quality of the sugar canes can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special compound fertilizer for sugarcane. 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 ...

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
