Embodiment Construction

[0032] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] In a flue-cured tobacco cultivation site in a mountainous area, an application experiment of soil ecological improvement methods for tobacco planting was carried out. The flue-cured tobacco is harvested in September of the first year, and the tobacco stems are pulled out in early October. In mid-October, cut the corn stalks into small pieces of 50-100cm, spread them in the original furrows, and use 500kg / mu. Use 2 kg / mu of organic waste fermented koji produced by Beijing Jingpuyuan Bioengineering Co., Ltd. to spread evenly on the corn stalks, and then cover with soil. The soil covering method is to cut the original ridge from the middle, make the soil on the ridge fall to the direction of the furrow, bury the corn stalks, and cover the soil with a thickness of about 7cm. After covering with soil, make the furrow slightly conca...

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-...
