Fertilizer special for crops

Abstract

The invention relates to the field of agriculture fertilizers, and especially relates to a fertilizer special for crops. The fertilizer comprises the following raw materials in parts by mass: 20-30 parts of urea, 15-17 parts of calcium phosphate, 11-14 parts of calcium superphosphate, 10-14 parts of potassium chloride, 12-15 parts of potassium sulfate, 10-12 parts of a silicon fertilizer, 7-12 parts of soybean meal, 9-12 parts of ferrous sulfate, 5-7 parts of magnesium sulfate, 7-8 parts of potassium dihydrogen phosphate, 6-10 parts of copper sulfate, 5-7 parts of zinc sulfate, 4-7 parts of manganese sulfate, and 60-70 parts of water. The fertilizer realizes fertilizer effects of long-acting, multiple effects, and high efficiency without pollution.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a crop chemical fertilizer. Background technique [0002] Most chemical fertilizers, namely chemical fertilizers, have the property of being easily soluble in water. They are easily dissolved by rainwater in the soil and are lost with the water flow, resulting in two adverse consequences of water pollution in reservoirs and rivers and loss of fertilizer in the soil. The effective time of chemical fertilizers is short , The growing season requires multiple fertilization, which not only pollutes the environment, but also cannot guarantee the effect. Contents of the invention [0003] The purpose of the present invention is to address the above problems and propose a crop chemical fertilizer, which realizes the long-acting, multi-effect, high-efficiency, and pollution-free effects of the chemical fertilizer. [0004] The technical solution of the present invention...
