Problems solved by technology

However, the nutrients contained in the biogas slurry do not have an exact and balanced ratio, and the application of biogas slurry alone cannot meet the nutrients required by eggplant.
[0005] The development of a special liquid fertilizer for eggplant based on biogas slurry is formulated according to the nutrient characteristics required for the growth and development of eggplant, and scientifically added the nutrients required for eggplant growth. Difficulties, as well as the secondary discharge of biogas slurry, the problem of polluting the environment, and can provide a special liquid fertilizer for eggplant to ensure stable and high yield of eggplant
So far, there is no special liquid fertilizer for eggplant based on biogas slurry

Abstract

The invention relates to a liquid fertilizer used for eggplant based on biogas slurry and its application method, which comprises the following steps by weight: 70-90 parts of biogas slurry, 10-15 parts of ammonium nitrate, 3-5 parts of dipotassium hydrogen phosphate, 5-8 parts of potassium chloride, 1-3 parts of calcium nitrate, 0.8-1.5 parts of ferrous sulphate, 0.5-0.8 parts of magnesium chloride, 0.2-0.5 parts of zinc sulfate, 0.5-1.5 parts of boric acid, 0.3-0.5 parts of manganese sulfate and 0.2-0.5 parts of ammonium molybdate. According to the invention, the biogas slurry which is obtained by anaerobic fermentation of livestock and poultry excrement and crop straw through a methane tank, the nutrient composition required by the growth of the eggplant can be scientifically added to prepare the liquid fertilizer. The liquid fertilizer has the advantages of comprehensive nutrition, sufficient raw material source, low cost and safe environmental protection. The liquid fertilizer is diluted by using clear water, and is taken as an eggplant foliar fertilizer for spraying or a nutrient solution for soilless culture, and can obviously improve the growth property of the eggplant, the incidence of disease is reduced, and the output is increased to more than 14%. The liquid fertilizer solves the problems of difficult application, difficult transportation and environmental pollution due to secondary discharge.

Description

technical field [0001] The invention relates to a special liquid fertilizer for eggplant based on biogas slurry and an application method thereof, belonging to the field of agricultural waste reuse. Background technique [0002] Eggplant is a popular vegetable. Eggplant is rich in nutrients, containing protein, fat, carbohydrates, vitamins, calcium, phosphorus, iron and other nutrients. In particular, the content of vitamin P is very high. Every 100 grams contains 750 mg of vitamin P, which is beyond the reach of many vegetables and fruits. [0003] Eggplant is a fat-loving crop, and the yield depends on the growth intensity of the plant. Planting eggplant well is to fertilize scientifically according to its different growth periods, so as to ensure the nutrients needed by eggplant and ensure its robust growth. If the nutritional conditions are good, there will be less flower drop, otherwise there will be more flower drop; malnutrition will increase the number of short-s...
