Special organic-inorganic compound fertilizer for rice, and preparation method of organic-inorganic compound fertilizer

Abstract

The invention discloses a special organic-inorganic compound fertilizer for rice, which is characterized by comprising the following raw materials in parts by weight: 25-30 parts of sweet potato vine, 9-14 parts of dry reed, 14-17 parts of biochar, 10-12 parts of hawthorn meal, 13-16 parts of sophora japonica residue, 5-8 parts of crab shell, 8-11 parts of animal dung, 2-3 parts of EM (Effective Microorganism) culture, 19-22 parts of urea, 12-17 parts of potassium chloride, 15-16 parts of calcium nitrate, 7-12 parts of silicate, 18-20 parts of yellow phosphorus slag, 5-9 parts of monoammonium phosphate, 6-7 parts of dicyandiamide, 3-4 parts of urea formaldehyde, 20-25 parts of borax and 14-15 parts of zeolite mineral powder. The special organic-inorganic compound fertilizer for the rice can improve the soil fertility of a rice field, improve a soil environment of the rice field, effectively control a rice disease, increase the yield of the rice, improve the quality of the rice, improve the utilization efficiency of a nutrient resource, coordinate with soil nutrient balance, facilitate improvement on the soil fertility, and realize successive high yield of the rice.

Description

field of invention [0001] The invention relates to the field of agricultural chemicals, in particular to a special organic-inorganic compound fertilizer for rice and a preparation method thereof. Background technique [0002] The fertilizers used by farmers in rice production are mainly urea, ammonium bicarbonate, diammonium phosphate and general-purpose ternary compound fertilizers. The phenomenon of nutrient imbalance caused by partial application of fertilizers is very serious, which not only affects the improvement of rice yield and quality , Reduce the utilization efficiency of nutrient resources, let alone coordinate the balance of soil nutrients, which is not conducive to soil fertilization and sustainable high yield of rice. [0003] The application of chemical fertilizers has played a key role in increasing agricultural income. However, due to the long-term application of chemical fertilizers, insufficient supply of organic fertilizers, and imbalances in the propor...

Problems solved by technology

However, due to the long-term application of chemical fertilizers, the supply of organic fertilizers is insufficient, and the proportion of various nutrients is out of balance, resulting in different degrees of damage to the ecological environment of farmland, soil physical and chemical properties and soil biota, affecting the quality of agricultural products to a certain extent

A large number of inorganic fertilizers are used, which seriously leads to the increase of harmful substances in crops, poor quality, and nutritional insufficiency. Secondly, the soil is easy to compact, the effect of drought resistance is poor, and the water retention performance also deteriorates. This seriously affects the normal growth of crops and poor economic benefits.
