Problems solved by technology

[0003] At present, the fertilizers used on eggplant in the market are mainly traditional fertilizer varieties, such as elemental urea, superphosphate, potassium chloride or nitrogen, phosphorus and potassium ternary compound fertilizers, etc., which generally do not contain medium and trace elements. Not only are the fertilizers poorly targeted, they cannot Give full play to the production-increasing effect of fertilizers, and because eggplant has a long growth period or harvest period, it needs to be topdressed many times, which is time-consuming and labor-intensive, and also increases production costs
[0004] In addition, there is a problem that the amount of fertilizer used in vegetable fertilization is too large, and the utilization rate of fertilizer is relatively low.
Heavy nitrogen is very common in eggplant production, and the utilization rate of nitrogen fertilizer is less than 30%. The unused nitrogen fertilizer or leaching into the water body causes eutrophication of the water body, or volatilizes to cause air pollution, or deposits in the soil, causing soil nitric acid Salt, nitrite enrichment
Excessive fertilization not only reduces the economic effect of farmers, but also brings environmental pollution, and long-term consumption of foods high in nitrate and nitrite will affect human health through the food chain, and in severe cases cause digestive tract cancer

Abstract

The invention provides a special slow control/release fertilizer for an eggplant. The fertilizer is characterized by comprising, in terms of mass percent, 0.05% to 0.08% of n-butyl triamine thiophosphate, 0.05 to 0.08% of hydroquinone and 0.24 to 0.28% of dicyandiamide. According to the invention, the special slow control/release fertilizer is prepared by combining macro-element, medium-element and trace-element fertilizers like nitrogen, phosphorus, potassium, calcium, magnesium, molybdenum, boron, zinc and iron with organic fertilizers like high-quality decomposed rapeseed dregs, chicken manure and grass carbon, adding a urease inhibitor and a nitrification inhibitor and carrying out mixing; the special slow control/release fertilizer has a slow release effect in soil, is rich in a variety of nutrient elements needed in growth of the eggplant, can meet demands of the eggplant for nutrients in different growth and development phases for a long time and effectively improves output of the eggplant.
