Carbon-power full water-soluble potato long-lasting drop irrigation special fertilizer and preparation method thereof

Abstract

The invention relates to the field of chemical fertilizers, in particular to a carbon-power full water-soluble potato long-acting drop irrigation special fertilizer and a preparation method thereof. The fertilizer comprises urea, monoammonium phosphate, industrial ammonium phosphate, potassium chloride, polyamino acid and trace elements and is specifically prepared from the following components inpercentage by weight: 38 to 40 percent of urea, 1 to 2 percent of monoammonium phosphate, 22 to 25 percent of industrial ammonium phosphate, 28 to 30 percent of potassium chloride, 1 to 5 percent ofdicyandiamide, 2 to 5 percent of amino acid and 1 to 2 percent of trace elements. The carbon-power full water-soluble potato long-acting drop irrigation fertilizer prepared with the preparation methoddisclosed by the invention has high nutrient content and can provide nitrogen, phosphorus and potassium with proper proportions for potato growth. By utilizing an inhibitor to control nitrogen and prolong the fertilizer efficiency period, the utilization rate of the fertilizer is improved; in addition, amino acid carbon power is utilized to supplement carbon, the development of a potato root system is promoted, and nutrients are fully absorbed, so that potato tubers are expanded and the yield of potatoes is improved.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a special carbon-energy full water-soluble potato long-acting drip irrigation fertilizer and a preparation method thereof. Background technique [0002] Potatoes are one of the most important crops in Western countries. They are planted in large areas in Russia, the United States, Poland and other countries. The average yield per unit area is 2.5-3 times that of China, and the utilization rate of chemical fertilizers is 20-30% higher than that in China. At the same time, although the scope of potato planting in my country is very wide, the output is relatively concentrated. Among them, the six provinces of Inner Mongolia, Hubei, Yunnan, Shaanxi, Shanxi, and Fujian account for 60% of the total output. Due to the complicated status of fertilization in different potato production areas in my country, according to the current situation of potato agricultural development, by 2020, ...

AI Technical Summary

Problems solved by technology

[0003] For a long time, my country has only paid attention to the application of nitrogen, phosphorus, and potassium fertilizers in potato production, but it has applied less or no organic fertilizers and medium and trace element fertilizers, which has led to poor physical and chemical properties of the soil, nutrient deficiency or imbalance, and stress. The growth of potatoes limits the improvement of their yield and quality, which affects the production level of potatoes

Unbalanced nutrient supply has become an obstacle to high-quality and high-yield potatoes

[0004] At present, most studies on balanced fertilization of potatoes focus on the effects of combined application of macronutrients on its yield and quality, while there are few studies on combined application of trace elements and amino acids.
