example 1

[0017] Example 1 (community test): In 2013, no-tillage cultivation of flue-cured tobacco on the original ridge was carried out in Fenghuang County, Xiangxi Autonomous Prefecture, Hunan Province. Open a 8-10cm deep and 8-10cm wide ditch in the middle of the ridge body, apply base fertilizer strips in the ditch, and backfill the original soil after fertilization; the amount of fertilizer applied is 50kg / mu of special base fertilizer + 10kg / mu of special topdressing fertilizer + 20kg / mu of active fertilizer , The seedling raising fertilizer is 5kg / mu (special seedling raising fertilizer), and the topdressing is 10kg / mu of special topdressing + potassium sulfate 20kg / mu. The distance between transplanting rows is 1.2m*0.5m. That is, the width of the ridge body is about 40cm, and the horizontal distance between the ridge bodies is about 1.2m. On the same ridge body, only one row of tobacco seedlings is transplanted vertically, and a hole is dug in the middle of the two tobacco plan...

[0031] Example 2: In 2013, no-tillage cultivation of flue-cured tobacco was carried out on the original ridge in Huayuan County, Xiangxi Autonomous Prefecture, Hunan Province. Open a ditch 8-10cm deep and 8-10cm wide in the center, apply base fertilizer strips in the ditch, and backfill the original soil after fertilization; the amount of fertilizer applied is 50kg / mu of special base fertilizer + 10kg / mu of special topdressing fertilizer + 20kg / mu of active fertilizer, and the seedlings are raised The fertilizer is 5kg / mu (special seedling raising fertilizer), and the topdressing is special topdressing fertilizer 10kg / mu+potassium sulfate 20kg / mu. The distance between transplanting rows is 1.2m*0.5m. That is, the width of the ridge body is about 40cm, and the horizontal distance between the ridge bodies is about 1.2m. On the same ridge body, only one row of tobacco seedlings is transplanted vertically, and a hole is dug in the middle of the two tobacco plants for transplanting...

Abstract

The invention relates to a no-tillage cultivation method with the capability of improving the production benefit of dry-land flue-cured tobacco. Aiming at the problems that a tillage working procedure is complicated, the used manpower is much, the labor cost is high, the land capability of tobacco-planting soil decreases, and the like in the conventional cultivation of current flue-cured tobacco, a cultivation technique through which the labor cost is saved, the soil fertility is improved, and the economic benefit of a tobacco grower is increased is provided. The specific operation comprises key steps of the reservation of a tobacco-planting ridge, the selection of the variety of the flue-cured tobacco, ditching and fertilizer application, a management measure, an executive fixed number of years, and the like. In comparison with plowing cultivation, by using the no-tillage cultivation method of the dry-land flue-cured tobacco, the operation of plowing (and intertillage and hilling) is omitted; certain improvement effects on the physical, chemical and microbiological properties of the soil exist; obvious influences are not brought to the yield and the output value of the dry-land flue-cured tobacco and the quality of a tobacco leaf; however, the production benefit of the flue-cured tobacco can be obviously increased; the labor cost which is RMB 400 or above per mu in a plowing (and the intertillage and the hilling) procedure is decreased; the no-tillage cultivation method of the dry-land flue-cured tobacco has a favorable application prospect in tobacco production.

Description

technical field [0001] The invention belongs to the field of economic crop cultivation, and in particular relates to a no-tillage cultivation technique capable of improving the production efficiency of dry-land flue-cured tobacco. Background technique [0002] Tobacco is one of the main economic crops in my country. With the development of modern tobacco agriculture, the traditional tobacco leaf production method has gradually developed in the direction of scale, intensification and specialization. However, the shortcomings of tobacco leaf production, such as complicated process, labor intensive and labor intensive, have not been fundamentally changed. At present, most of the tobacco planting areas in dry land are mountainous areas with small fields, which are basically traditional farming methods. Plowing, ditching, and intertillage soil cultivation are mainly manual operations. Not only is tobacco planting labor-intensive, but also the traditional The soil fertility of th...
