Special organic-inorganic compound fertilizer for sugarcane and preparation method of special organic-inorganic compound fertilizer

Abstract

The invention provides a special organic-inorganic compound fertilizer for sugarcane. The special organic-inorganic compound fertilizer is prepared from the following raw materials in parts by weight: 20-25 parts of bagasse, 10-12 parts of vinasse, 10-15 parts of straw, 13-20 parts of pig manure, 13-20 parts of cow dung, 7-11 parts of edible fungi residue, 6-15 parts of rice chaff, 2-10 parts of household garbage, 1-7 parts of plant ashes, 10-12 parts of vermiculite, 5-7 parts of calcium superphosphate, 2-5 parts of potassium sulfate, 5-7 parts of urea, 0.05-0.25 part of zinc sulfate, 0.08-0.2 part of borax, 0.3-0.5 part of phosphate solubilizing bacteria, 0.1-0.3 part of potassium bacteria, 0.3-0.5 part of azotobacter, 0.5-0.8 part of photosynthetic bacteria and 5-10 parts of an insecticide. The invention further provides a preparation method of the special organic-inorganic compound fertilizer for sugarcane. The special organic-inorganic compound fertilizer for sugarcane is scientific in ratio of nitrogen, phosphorus and potassium, rich in microelements such as zinc and boron, low in chemical fertilizer content, and lasting in fertilizer effect, and has a certain pest control effect.

Description

technical field [0001] The invention relates to the field of fertilizers, more specifically, the invention relates to a special organic-inorganic compound fertilizer for sugarcane and a preparation method thereof. Background technique [0002] Sugarcane is an important sugarcane crop in my country. It has a long production cycle and requires a large amount of fertilizer. Fertilization is one of the key technologies for high-yield, high-sugar and efficient cultivation of sugarcane. However, the proportion of nitrogen, phosphorus and potassium in many sugarcane special fertilizers is improper or out of balance, and the content of trace elements such as zinc and boron is also seriously lacking, which seriously affects the growth and development of sugarcane plants. In addition, the current special fertilizers for sugarcane are mostly chemical fertilizers, which will pollute the soil and destroy the soil structure and soil ecosystem if used for a long time. Therefore, it is nec...
