Compound fertilizer special for promoting crop growth

Abstract

The invention discloses compound fertilizer special for promoting crop growth. The compound fertilizer comprises, by weight, 40-50 parts of ammonium nitrate, 30-40 parts of bagasse, 30-40 parts of peanut meal, 20-40 parts of straw powder, 20-40 parts of alfalfa meal, 15-30 parts of corn gluten meal, 10-30 parts of hydrolyzed feather meal, 20-30 parts of rice chaff, 10-15 parts of shii-take residues, 5-8 parts of EM bacteria, 10-15 parts of magnesium hydrogen phosphate, 20-30 parts of urea, 22-30 parts of nitrate of potash, 15-20 parts of potassium metaphosphate, 4-5 parts of zinc nitrate, 10-20 parts of manganese phosphate, 2-8 parts of magnesium humate, 3-6 parts of sodium humate, 10-20 parts of sepiolite, 10-20 parts of expanded perlite and 10-15 parts of montmorillonoid. The compound fertilizer special for promoting crop growth can effectively solve the problems that soil is hardened, the drought resisting effect is poor and soil fertility is low.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer, in particular to a special compound fertilizer for promoting the growth of crops. Background technique [0002] The application of chemical fertilizers has played a key role in increasing agricultural incomes for many years. However, due to the long-term application of chemical fertilizers, insufficient supply of organic fertilizers, and imbalances in the proportion of various nutrients, the ecological environment of farmland, soil physical and chemical properties, and soil biota have been damaged to varying degrees, and the quality of agricultural products has been affected to a certain extent. Therefore, chemical fertilizer pollution has become a major public hazard in the world today. The current status of soil resources in my country urgently needs to supplement soil organic matter through artificial measures to ensure the level of agricultural planting and the quality of crop pro...

AI Technical Summary

Problems solved by technology

[0003] my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large number of inorganic fertilizers are used, which seriously leads to the increase of harmful substances in crops, poor quality, and incomplete nutrition. Secondly, the soil is easy to harden. The drought resistance effect is poor, and the water retention performance is also deteriorated, which seriously affects the normal growth of crops and poor economic benefits
