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 water-soluble fertilizer for plant growth comprises, by weight, 1-3 parts of zinc sulfate, 2-7 parts of ferric sulfate, 3-8 parts of potassium sulfate, 4-6 parts of calcium superphosphate, 30-50 parts of urea, 20-33 parts of nitric nitrogen fertilizer, 3-5 parts of ethylenediamine, 5-10 parts of potassium tripolyphosphate, 2-6 parts of triple superphosphate, 7-18 parts of boron-phosphorous ore powder and 6-12 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 trace 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, resulting ...
