Special fertilizer for drought resistance of potatoes and preparation method thereof

Abstract

The invention discloses a special fertilizer for drought resistance of potatoes. The special fertilizer is mainly prepared from the following raw materials: 61%-96.4% of inorganic salt fertilizer, 5%-12% wine residues, 3%-8% rape cake, 1.5%-5% sodium polyacrylate, 0.5%-1.5% EDTA, and 0.03%-0.12% diethyl aminoethyl hexanoate. The special fertilizer for drought resistance of the potatoes disclosed by the invention is balanced in nutrition, sufficient in nutrient supply to a potato field, and good in effect on quality and yield of the potatoes; the produced potatoes are large in size, smooth, good in taste, and high in yield; the cold resistance, the drought resistance and the disease resistance of the potatoes can be enhanced; the fertilizer has a good ecological effect; the problems that the soil of the potato field is coarse in texture and poor in water retaining capacity are solved; nutrition can be supplied to the potatoes; the soil nutrient balance is harmonized; and the quality and the yield of the potatoes are increased. The preparation method of the special fertilizer for drought resistance of the potatoes disclosed by the invention is available in raw materials, simple in operation and easy to implement; the prepared special fertilizer is stable and reliable in quality; full absorption of potatoes on the nutrient elements is facilitated; the yield of the potatoes is greatly increased; and the rate of growth can reach 20.26%-40.12%.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and in particular relates to a special fertilizer for potato drought resistance and a preparation method thereof. technical background [0002] The cold and cool irrigation area at an altitude of 1650-2800m in Gansu Province has long sunshine hours and large temperature differences between day and night, making it an ideal place for potato planting. From 2001 to 2013, new potato varieties such as Atlantic, Xiapoti, and Favorita were introduced from abroad. A processing potato production base of 10,000 mu has been built, with an annual output of 250 million tons of potatoes. The potato industry has developed into one of the important pillar industries for increasing farmers' income in Gansu Province. At present, the main problems of the potato industry are becoming more and more prominent: ①The potato planting area is large, and the continuous cropping period of 8-10 year...

AI Technical Summary

Problems solved by technology

At present, the main problems of the potato industry are becoming more and more prominent: ①The potato planting area is large, and the continuous cropping period of 8-10 years accounts for more than 50%, which leads to the imbalance of soil nutrient ratio, and the physiological diseases of zinc deficiency often occur; ②Farmers have long-term Extensive application of urea chemical fertilizers destroys the aggregate structure of the soil and compacts the soil, which is not conducive to the expansion of potato tubers; ③The ratio of nitrogen and phosphorus inputs of chemical fertilizers to organic fertilizers is 1:0.28, resulting in a decrease in soil organic matter content, soil The water storage function is weakened; ④The special fertilizer sold on the market does not contain organic matter and has no water retention effect, which affects the sustainable development of the potato industry
