Special tomato fertilizer and preparation method thereof

Abstract

The invention discloses a special tomato fertilizer and a preparation method thereof. The special tomato fertilizer is mainly prepared from the following raw materials in parts by weight: 28 to 38 parts of wine lees, 25 to 35 parts of di-ammonium phosphate, 12 to 23 parts of potassium chloride, 7 to 13 parts of carbamide, 2 to 5.5 parts of calcium nitrate, 1.5 to 3.2 parts of zinc sulfate, and 1 to 2.5 parts of sodium polyacrylate. The special tomato fertilizer is balancing in nutrition, can sufficiently supply nutrients for a tomato field to improve the quality and the yield of tomatoes; the tomatoes harvested from the tomato field are large in size, full, round, and smooth, taste good and are high in yield; the cold resistance, drought resistance and disease resistance of the tomatoes can be enhanced, so that the ecologic effect is favorable; the problems of coarse soil texture and poor water retaining capacity of the tomato field are solved; nutritions can be supplied to the tomatoes while the soil nutrient balancing can be coordinated, so that the quality and the yield of the tomatoes are improved. The preparation method has the advantages that the raw materials are easy to obtain; the operation is simple; the application is easy; the special tomato fertilizer prepared according to the method is stable and reliable in quality; the tomatoes can absorb various nutrient elements better, so that the yield is greatly improved; the stimulation ratio is up to30.39 to 41.37 percent.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and in particular relates to a special tomato fertilizer and a preparation method thereof. technical background [0002] The planting area of ​​tomatoes in solar greenhouses in the Hexi Corridor of Gansu Province has grown to 66,000 mu. At present, the main problems that are becoming more and more prominent are: excessive application of nitrogen and phosphorus fertilizers, serious shortage of organic fertilizer input, imbalance of macronutrients and micronutrients in the soil, calcium deficiency in tomatoes Physiological diseases such as zinc deficiency and zinc deficiency often occur; the soil organic matter content is low, and the ability to retain water and fertilizer is weak; while traditional compound fertilizers do not contain organic matter, and do not have the functions of drought resistance and soil improvement, resulting in a decline in tomato yield and quality,...

Problems solved by technology

[0002] The planting area of ​​tomatoes in solar greenhouses in the Hexi Corridor of Gansu Province has grown to 66,000 mu. At present, the main problems that are becoming more and more prominent are: excessive application of nitrogen and phosphorus fertilizers, serious shortage of organic fertilizer input, imbalance of macronutrients and micronutrients in the soil, calcium deficiency in tomatoes Physiological diseases such as zinc deficiency and zinc deficiency often occur; the soil organic matter content is low, and the ability to retain water and fertilizer is weak; while traditional compound fertilizers do not contain organic matter, and do not have the functions of drought resistance and soil improvement, resulting in a decline in tomato yield and quality, which seriously affects the greenhouse vegetable industry. sustainable development

Chinese patent CN103159561A discloses a special enhanced fertilizer for tomatoes, which is made by mixing urea, ammonium bicarbonate, superphosphate, potassium nitrate, potassium chloride and additives. Although this fertilizer avoids single fertilization, the organic matter content in the fertilizer is small. Poor soil water retention capacity, lack of drought resistance, and unbalanced nutrition
