Compound fertilizer special for rice

Abstract

The invention discloses a compound fertilizer special for rice. The compound fertilizer is prepared from the following raw materials in parts by weight: 15 to 20 parts of urea, 6 to 12 parts of superphosphate, 8 to 14 parts of potassium chloride, 1 to 3 parts of magnesium sulfate, 1 to 2 parts of borax, 1 to 2 parts of humic acid, 1 to 2 parts of medium trace elements, 1 to 2 parts of amino acid, 15 to 25 parts of rapeseed cake fertilizers, 15 to 22 parts of bagasse, 7 to 12 parts of plant ash, and 0.1 to 0.3 part of an EM (Effective Microorganisms) microbial agent. The compound fertilizer special provided by the invention has reasonable collocation of components, can promote balanced and reasonable absorption of the rice for nutritional components through the synergistic effect of various nutritional components and adapts to a law of fertilizer requirement of the rice growth and development, thereby being capable of obviously increasing the rice yield and quality.

Description

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

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
