Problems solved by technology

However, because the farmland managers did not apply the crop slow-control agent according to the growth law of the crops, they over-controlled the growth of the crops, so that the premature aging of the crops in the later stage, or even death occurred from time to time, resulting in serious production reduction

The macroelement-containing water-soluble fertilizer is a fertilizer for plant growth, and comprises the following raw materials in parts by weight: 1 to 3 parts of zinc sulfate, 2 to 7 parts of ferric sulfate or ferrous sulfate, 3 to 8 parts of potassium sulfate, 4 to 6 parts of superphosphate calcium, 30 to 50 parts of urea, 20 to 33 parts of a precipitated phosphate fertilizer, 3 to 5 parts of citric acid, 5 to 10 parts of potassium tripolyphosphate, 2 to 6 parts of calcium triple superphosphate, 7 to 18 parts of borophosphate ore powder and 6 to 12 parts of ammonium phosphate.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizer manufacturing, and more specifically relates to a water-soluble fertilizer containing a large amount of elements, which is a fertilizer for plant growth. Background technique [0002] In traditional agricultural production practices, crops grow naturally. Under the conditions of excessive topdressing or suitable watering and good weather conditions, crops are prone to crazy growth. In this way, due to excessive vegetative growth, reproductive growth will be greatly affected, resulting in a substantial reduction in crop production. In recent years, the application of plant growth regulators has brought the phenomenon of crazy growth of crops under control. However, because farmland managers did not apply crop slow-control agents according to the growth rules of crops, they over-controlled the growth of crops, so that premature aging and even death of crops occurred from time to time...
