The invention relates to a flue-cured tobacco fertilizer applying management method and a fertilizer applying device, and belongs to the field of agricultural planting and culturing. The method includes the steps of selecting a field for planting flue-cured tobacco, wherein the soil which is thick in soil layer, loose and fertile in soil quality, high in water-retaining and fertilizer-retaining capacity and rich in organic matter and suitable for the growth of the flue-cured tobacco is selected first; determining the line spacing, row spacing and tobacco planting amount of the flue-cured tobacco; determining the fertilizer applying mode, wherein a base fertilizer accounts for 60%, a primary topdressing fertilizer accounts for 20%, and a secondary topdressing fertilizer accounts for 20%; conducting the hole fertilizer applying mode; applying the fertilizers before sowing, wherein the before-sowing fertilizer applying amount distribution ratio, fertilizer applying period and fertilizer applying mode are determined, the base fertilizer is applied before sowing, and the organic fertilizer serves as the main fertilizer; determining the topdressing types, amounts, methods and periods. The effectiveness of flue-cured tobacco fertilizer applying is ensured, and economic benefits are improved. By means of the fertilizer applying device, mechanical fertilizer applying is realized, the fertilizer applying efficiency is improved, and meanwhile the fertilizer applying depth and uniformity are ensured.
Description
technical field [0001] The present application relates to the field of agricultural planting and cultivation, in particular to a flue-cured tobacco fertilization management method and a flue-cured tobacco fertilization device. Background technique [0002] Tobacco is one of the important economic crops in China. How to improve the yield and quality of tobacco is an important issue that directly affects the income of tobacco farmers and the development of the tobacco industry. Reasonable fertilization is an important guarantee for high-quality and suitable production of flue-cured tobacco. Among various nutritional elements, nitrogen is an important mineral element that affects the growth and development of flue-cured tobacco and the quality of tobacco leaves. [0003] With the increase of nitrogen application rate, each agronomic trait index had an increasing trend, but when the nitrogen application rate was too large, the increasing trend slowed down or was not obvious. Th...
