Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer for wheat. Background technique [0002] Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products. The demand for pollution-free and green food is increasing year by year. The current wheat planting uses There are many types of fertilizers, and N, P, and K compound fertilizers are mainly used. They are mainly composed of three inorganic elements, N, P, and K, and can meet the growth needs of wheat in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of wheat, and the promotion effect on wheat growth is not obvious. Organic fertilizers are processed by biomass, anima...

Problems solved by technology

However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of wheat, and the promotion effect on wheat growth is not obvious. Organic fertilizers are processed by biomass, animal and plant waste, and plant residues. It eliminates the toxic and harmful substances in it, and is rich in a large number of beneficial substances. It can not only provide comprehensive nutrition for crops, b
