Abstract
The invention discloses a special compounded fertilizer for potatoes. The special compounded fertilizer is prepared from the following raw materials in parts by weight: 30-40 parts of urea, 12-20 parts of calcium superphosphate, 15-25 parts of potassium sulfate, 3-5 parts of ferrous sulfate, 1-3 parts of sodium humate, 1-3 parts of boric acid, 0.3-0.5 part of EDTA chelate zinc, 20-24 parts of meerschaum, 15-20 parts of rapeseed cake fertilizer, 3-5 parts of cane sugar, 10-15 parts of earthworm cast, 8-10 parts of bamboo vinegar and 0.3-0.5 part of compounded microbial agent. According to the special compounded fertilizer for the potatoes, 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 potatoes to the nutritional ingredients can be promoted, the fertilizer requirement law of the growth and development of the potatoes is adapted, and thus the yield and quality of the potatoes 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 potatoes. 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...
