A method for ecological improvement of tobacco planting soil

Abstract

A method for ecologically improving tobacco-planting soil is disclosed. In October of the first year, after flue-cured tobaccos or corns are harvested, straws are chopped down and spread on furrows directly without plowing soil, straw decomposition accelerator or other microbe fertilizers are spread on the straws, and then ridge soil is dumped in furrows to cover and bury the straws. Green manure is applied in lines, common vetch green manure is applied on the soil surface burying the straws in lines with a width of 55-65cm, and the green manure is buried by ridging without plowing. In the next year, 10-15days before transplanting flue-cured tobaccos, flue-cured tobacco base fertilizer is applied on the green manure according to the line-spacing requirements of flue-cured tobaccos, soil is gathered to the green manure from two sides of the green manure to bury the green manure and ridge for planting flue-cured tobaccos. The method effectively improves soil, lowers production investment, ensures high yield, improves the physical properties of the soil, and increases organic matters and nutrients of the tobacco-planting soil. Moreover, the microbe amount and enzyme activity of the soil and the tobacco leaves quality are improved, the soil quality is retained and improved, and continuous flue-cured tobacco production and development in tobacco areas are facilitated.

Description

technical field [0001] The invention relates to a soil ecological improvement method for tobacco planting. Background technique [0002] Flue-cured tobacco is one of the important economic crops in my country. Due to the long-term continuous cropping and continuous application of chemical fertilizers, the development mode of emphasizing the use of fertilizers and ignoring cultivation has deteriorated the soil environment and soil quality of tobacco fields, affecting the effective and sustainable use of land resources, resulting in the reduction of tobacco leaf quality and industrial availability and the decline of tobacco planting benefits. Become an important factor limiting the production of flue-cured tobacco, soil improvement for tobacco planting is imminent. [0003] In soil improvement, the traditional straw returning to the field is to apply or cover the straw when flue-cured tobacco is ridged. Since the straw is not completely decomposed in the early stage of flue-...

AI Technical Summary

Problems solved by technology

Microbial fertilizers can indeed improve the aroma and quality of tobacco leaves, and also have a significant effect on increasing the aroma. However, the application of microbial fertilizers causes soil bulk density to increase, soil arability to deteriorate, soil organic matter content to decrease greatly, and soil physical and chemical properties to deteriorate. Tobacco is not sustainable
