Fulvic acid water-soluble foliar fertilizer and preparation method thereof

Abstract

The invention discloses a fulvic acid water-soluble foliar fertilizer and a preparation method thereof. The fulvic acid water-soluble foliar fertilizer comprises the following active ingredients in parts by weight: 30-40 parts of sodium fulvate, 40-50 parts of potassium dihydrogen phosphate, 20-30 parts of urea, 10-15 parts of ammonium sulfate, 25-35 parts of waste silk, 15-20 parts of feather meal, 5-10 parts of monosodium glutamate leftovers, 2-3 parts of zinc nitrate, 1-2 parts of manganese sulfate, 1-2 parts of magnesium sulphate, 0.5-1.5 parts of sodium molybrate, 1-2 parts of boric acid, 0.5-1 part of thylenediaminetetraacetic acid disodium, 10-15 parts of kelp residues, 5-10 parts of rape seed cakes, 8-12 parts of soyabean meal, 5-10 parts of brewer's grain, 8-12 parts of waste methane liquid, 2-3 parts of luffa stem, 1.5-2.5 parts of cortex meliae, 1-2 parts of tung tree roots, 2-3 parts of radix sophorae flavescentis, 1-2 parts of thunder god vine, and 2-3 parts of castor plant leaves. The foliar fertilizer is complete and balanced in nutrients, high in fertilizer efficiency, high in fertilizer utilization rate, capable of fast replenishing the nutrition for crops, also has the effects of disease prevention, antibiosis, insect killing, insect expelling, flower retention, fruit retention and the like, is obvious in effects of reducing the plant disease and insect pest of crops, reducing the use of chemical pesticide, promoting fast growth of crops, enhancing the stress tolerance of crops, improving the quality of crops and increasing both production and income, and has tremendous economic benefits.

Description

technical field [0001] The invention relates to a fulvic acid water-soluble foliar fertilizer and a preparation method thereof, belonging to the technical field of agricultural fertilizers. Background technique [0002] Foliar fertilizer is a fertilizer that directly applies the nutrients needed by the crops to the foliage for the purpose of leaf absorption. It is an important supplement to soil fertilization. A balanced supply of nutrients is the key to high-quality and high-yield crops. The fertilizer effect of foliar fertilizer is finally reflected in the degree of increase in crop production and income. For a long time, my country's foliar fertilizers have been dominated by mononutrient foliar fertilizers, which cannot meet the various nutrients required for crop growth. Therefore, it is important to develop a variety of nutrient foliar fertilizers that meet the needs of crops with multiple nutrients economic benefits. Contents of the invention [0003] The purpose...
