[0162] Special blended (BB) fertilizer and / or compound fertilizer and / or compound fertilizer compound fertilizer for facility tomato and its application method
[0163] This example was carried out in Shixinzhuang, Dakoutun Town, Baodi District, Tianjin from 2013 to 2015, and the facility tomato cultivation stubble was a spring stubble-autumn delayed cultivation production mode. The number of times of fertilization during the whole growth period of facility tomato is 4 times, that is, the first panicle expansion fertilizer, the second panicle expansion fertilizer, and the third panicle expansion fertilizer in the special base fertilizer before transplanting and planting and topdressing special fertilizer.

The invention discloses a method for preparing and applying a special fertilizer for regional facility tomatoes based on a QUEFTS model. The method for preparing and applying a special fertilizer for facility tomatoes is light, simple, quantitative and reasonable and has a regionalization characteristic. In a complex tomato fertilization system, growth environment and soil fertility of tomatoes are evaluated through key parameters such as available yield, yield response and relative yield of tomatoes. A nutrient demand proportion of nitrogen (N), phosphorus (P2O5) and potassium (K2O) of the special fertilizer for facility tomatoes and a corresponding recommended fertilization method are rapidly and accurately provided. The method is a chemical fertilizer production and application reduction technology, can effectively improve yield of tomato crops and a utilization rate of a fertilizer, reduces environmental pollution, improves soil fertility, is efficient, easy to implement and widely applicable, can protect the environment, and provides a technical guarantee for industrialized production of a specific bulk blend (BB) fertilizer and / or a compound fertilizer and / or a compound blend fertilizer special for facility tomatoes 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 regional tomato special fertilizer based on the QUEFTS model. Background technique [0002] Shi vegetables are also called greenhouse vegetables, because most of them are plastic greenhouse facilities in my country, which is a new industry developed in the 1990s, and the current planting area has reached 1.4 million hectares nationwide. Due to the rapid development, plant nutrition and fertilizer scientific and technological workers have not yet developed a mature fertilization technology and lack special fertilizers. Farmers in our country fertilize blindly on vegetables in facilities. According to the survey results, the vegetables in the solar greenhouse and plastic shed in Shouguang, Shandong Province are generally applied with 120-225t of organic fertilizer (hm 2 .a), diammonium phospha...
