Problems solved by technology

However, there are problems such as serious waste of water and fertilizer resources and aggravated environmental pollution in corn production, which restrict the sustainable development of corn production in my country. It is an inevitable trend to promote the integration of water and fertilizer for corn drip irrigation
[0003] At present, the fertilizers used in the integrated technology of corn drip irrigation and water have problems such as simple production process, low technical content, low nutrient absorption and utilization efficiency, easy blockage in field application, and relatively expensive prices. The main manifestations are: using conventional chemical fertilizers, including diammonium , monoammonium, etc., mixed with urea, heated and dissolved in water for drip irrigation and fertilization, and potassium dihydrogen phosphate and urea are mixed for drip irrigation and fertilization by simple manual or concrete mixing. Due to their limited purity and solubility, these fertilizers are prone to blockage of drip irrigation equipment. Increase production costs and other issues; in addition, most of the soluble fertilizers sold on the market are used for commercial crops, and there is still a lack of special drip irrigation fertilizers suitable for field crops corn

Abstract

The invention discloses soluble fertilizer for corn drip irrigation. The soluble fertilizer comprises, by mass percentage, 30-45% of ammonium bicarbonate, 15-30% of potassium phosphate monobasic, 10-35% of potassium chloride, 1-5% of biological bacterium, 2-10% of sodium humate, 1-2% of trace element and 2-3% of amino acid. The soluble fertilizer has the advantages that the defects that existing drip irrigation fertilizer is single in component and poor in solubility and causes drip irrigation equipment blocking are overcome, and the soluble fertilizer is comprehensive in nutrition and good in solubility, does not block drip irrigation equipment and can reduce production cost.

Description

technical field [0001] The invention belongs to the application field of agricultural irrigation, and is specifically a soluble fertilizer for corn drip irrigation. Background technique [0002] Corn (Zea mays L.) is the food crop with the highest total yield in the world. In my country, corn is sown in a large area and widely distributed. It is one of the main grains for people in the arid and semi-arid areas of the north. However, there are problems such as serious waste of water and fertilizer resources and aggravated environmental pollution in corn production, which restrict the sustainable development of corn production in my country. It is an inevitable trend to implement the integrated technology of corn drip irrigation with water and fertilizer. [0003] At present, the fertilizers used in the integrated technology of corn drip irrigation and water have problems such as simple production process, low technical content, low nutrient absorption and utilization efficien...
