Compound fertilizer special for seedlings

Abstract

The invention provides a compound fertilizer special for seedlings. The compound fertilizer is mainly prepared from 6-18 parts of ammonium phosphate, 14-20 parts of potassium nitrate, 6-10 parts of calcium phosphate, 2-3 parts of zymophyte, 10-21 parts of magnesium phosphate, 65-95 parts of green manure, 12-15 parts of citric acid and 7-14 parts of ammonium bicarbonate. The compound fertilizer hasthe advantages of being high in utilization rate, high nutritional ingredient and capable of effectively promoting the seedling production efficiency, shortening the biological cycle, reducing pests,increasing the yield and effectively enhancing the economic benefit; meanwhile, the invention provides a biological fertilizer source which has great effect on improving soil; the soil fertility is effectively increased, the dosage of the chemical fertilizer can be reduced, the resources are saved, environmental protection is achieved, and meanwhile the growth rate of seedlings can be greatly increased.

Description

technical field [0001] The invention belongs to the technical field of seedling chemical fertilizers, and in particular relates to a special compound fertilizer for seedlings. Background technique [0002] The chemical fertilizer containing the nutrient elements nitrogen, phosphorus and potassium of seedlings made by chemical method or mixed method is compound chemical fertilizer; compound chemical fertilizer can adjust and solve the contradiction between seedling fertilizer and soil, realize the balanced supply of various nutrients, and meet the growth needs of seedlings ; But traditional chemical fertilizers can only supplement a single element that is lacking in the growth process of seedlings, which greatly reduces the growth efficiency of seedlings, not only increases labor, but also causes waste of resources and pollutes the environment. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the defects in the above-mentio...
