Total-nutrient microbial fulvic acid water-soluble fertilizer and preparation method thereof

Abstract

The invention provides a total-nutrient microbial fulvic acid water-soluble fertilizer. The fertilizer comprises the following formula components in percentage by mass: 30-60% of 52% water-soluble potassium sulfate, 20-30% of 73% water-soluble monoammonium phosphate, 5-30% of 46% urea, 1-2% of 50% water-soluble silicon fertilizer, 0.8-1.2% of chelated water-soluble medium trace element fertilizer, 5-7% of 65% water-soluble mineral source potassium fulvate, 0.4-0.6% of Trichoderma harzianum T-22 which is 20 billion per gram, and 0.5-1% of bacillus subtilis which is 200 billion per gram. The fertilizer has the beneficial effects that: the fertilizer has the characteristics of full nutrition, full water solubility, no pollution and sterilization, not only contains macroelements, medium elements and microelements required by crop growth, but also contains mineral source potassium fulvic acid and a microbial agent, so that plants can absorb quickly and root quickly, the yield is obviously increased, the growth of soil root nematodes and harmful germs can be inhibited, the soil is improved, diseases and insect pests are reduced, and the crop disease resistance is enhanced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-soluble fertilizer with total nutritional microorganism fulvic acid and a preparation method thereof. Background technique [0002] Fertilizer is the material guarantee for the sustainable development of agriculture and the material basis for increasing grain production. In my country, chemical fertilizers account for more than 20% of agricultural costs, making my country the world's largest producer and consumer of chemical fertilizers. However, increasing input of chemical fertilizers has not continued to increase crop yields. The reason for this phenomenon is the use of fertilizers. low rate. Total nutrition refers to the macronutrients such as nitrogen, phosphorus, and potassium required for plant growth, the secondary elements such as calcium, magnesium, sulfur, and silicon, and the trace elements such as boron, iron, copper, manganese, and zinc. At present, the...

Problems solved by technology

[0004] At present, the formula of most water-soluble fertilizers is too single, and there are very few water-soluble fertilizers with full nutrition. The diversity of water-soluble fertilizer products needs to be improved
