Abstract

Belonging to the field of biological products, the invention in particular relates to a functional nutrition agent for phytoremediation and its preparation method. The functional nutrition agent comprises the following raw materials by weight: 5%-8% of urea, 13%-22% of phosphoric acid, 3%-7% of potassium carbonate, 2%-7% of ammonium sulfate, 1%-5% of EDTA iron, 0.5%-3% of HEDTA zinc, 0.5%-3% of EDTA manganese, and 50%-70% of a leonardite extracted liquid. The functional nutrition agent for phytoremediation prepared by the invention can promote plant root growth, get rid of runt seedlings, rapidly recover the vitality of root systems and crops, relieve injury caused by climate, phytotoxicity, fertilizer damage, hormone poisoning as well as pest and disease damage, and can promote fruit enlargement, and increase crop yield. The functional nutrition agent has the advantages of small dosage, convenient use, and labor saving. Also, the preparation process is simple, green, and environment-friendly.

Description

technical field [0001] The invention belongs to the field of biological products, in particular to a functional nutrient for repairing plants and a preparation method thereof. Background technique [0002] With the acceleration of the urbanization process, the area of ​​effective agricultural land has gradually decreased, and with the continuous growth of the population, the demand for agricultural products has also continued to increase, and the contradiction between food supply and demand has become increasingly prominent. In order to obtain higher yields in agricultural production, in addition to implementing measures such as adjusting the planting structure and increasing the multi-cropping index of cultivated land, a large number of chemical fertilizers, pesticides, and hormones have been used in cultivation to blindly pursue yields, resulting in a serious decline in the quality of agricultural products. Pesticides and hormones cause phytotoxicity and poisoning o...
