Abstract

The invention provides a special tobacco fertilizer for improving the water retention capacity of tobacco planting soil. The fertilizer is prepared from the following raw materials in parts by weight:10 to 15 parts of crop straw, 20 to 25 parts of acrylamide, 1 to 3 parts of N, N-methylene bisacrylamide, 30 to 40 parts of acrylic acid, 3 to 5 parts of potassium persulfate, 15 to 20 parts of ardealite, 20 to 30 parts of diatomite, 6 to 8 parts of urea, 4 to 6 parts of potassium nitrate and 18 to 22 parts of potassium sulfate. The special fertilizer for tobacco prepared by the technical schemehas excellent water-retaining property and good slow release property, can significantly improve the water-retaining capacity and water-retaining capacity of soil, improve the drought resistance of crops and reduce the irrigation frequency, enables nutrients to be slowly released and improves the utilization rate of the fertilizer. The invention provides a new direction for large-scale applicationof the water-retaining slow-release fertilizer in the fields of agriculture and the like.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, in particular to a special tobacco fertilizer for improving the water retention performance of tobacco planting soil. Background technique [0002] Soil moisture is the foundation of tobacco growth. The life activities of tobacco can only be carried out smoothly under the ecological conditions with suitable water. However, tobacco is mostly planted in mountainous and hilly areas. Due to the limitation of terrain conditions, the irrigation conditions are generally poor. When it is exposed to water, it will affect the metabolic activities of the tobacco plants, inhibit the growth and development, and seriously affect the yield and quality of tobacco leaves. Therefore, efficient use of limited water resources and improvement of soil water retention in tobacco planting are crucial for the sustainable development of high-quality tobacco leaves. [0003] There are many factors affecting soil ...
