Method for preparing and applying QUEFTS model based regionalized facility eggplant special fertilizer

Abstract

The invention discloses a method for preparing and applying a QUEFTS model based regionalized facility eggplant special fertilizer, and provides a light, simple, quantitative and reasonable method for preparing and applying the QUEFTS model based regionalized facility eggplant special fertilizer. According to the method, the growth environment and soil fertility condition of eggplant crops are evaluated through key parameters such as yield, yield response and relative yield of eggplants in a complex eggplant fertilization system, and the nutrient demand proportion of nitrogen (N), phosphorus (P2O5) and potassium (K2O) of the special fertilizer for the facility eggplants and the corresponding recommended fertilization method are rapidly and accurately provided. The method is a chemical fertilizer production and application reduction technology which effectively improves the yield of eggplant crops and the utilization rate of the fertilizer, reduces environmental pollution, improves soil fertility, is efficient and easy to implement, and is widely applicable to environmental protection; technical guarantee is provided for industrialized production of the BB fertilizer special for the facility eggplant and / or the compound fertilizer special for the facility eggplant and / or the compound fertilizer with regional characteristics.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer production and balanced fertilization, in particular to a method for compounding and applying special fertilizer for eggplant in regionalized facilities based on the QUEFTS model. Background technique [0002] Eggplant has formed a high-efficiency and energy-saving solar greenhouse, plastic shed, and three-way plastic film covering annual serial protection cultivation system for eggplant in my country. Without heating, eggplant can be produced throughout the year and supplied year-round. With the increase of production area year by year, especially the introduction of some new varieties, the requirements for production technology are getting higher and higher, and the requirements for the output and quality of eggplant are also getting higher and higher, and there are many problems in production. Among them, the most important problem is the lack of special fertilizers and mature ferti...

Problems solved by technology

Among them, the most important problem is the lack of special fertilizers and mature fertilization technology, and the phenomenon of blind fertilization

In addition, due to the large amount of fertilization and low nutrient utilization rate, a large amount of nitrogen is leached into the groundwater, causing the content of nitrate nitrogen (NO3-) in the groundwater to seriously exceed the standard
