Labor-saving flue-cured tobacco cultivation method

Abstract

The invention relates to a labor-saving flue-cured tobacco cultivation method, which belongs to a flue-cured tobacco cultivation method. The method is as follows: after tobacco leaves are harvested annually, tobacco stems are cut at roots on the surfaces of ridges, the cut tobacco stems are removed out of tobacco fields, and stubbles are left in the ridges, so that the ridges can be well protected; in the spring of next year and before tobaccos are planted, weedicide is applied for one time in order to control the growth of weeds, and when tobaccos are planted, pitting, fertilization and tobacco planting are carried out on the ridges; the surfaces of the ridges are then tidied up, weeds are removed, and the ridges are covered with mulching films when the soil moisture is sufficient, so that the normal growth of flue-cured tobaccos can be promoted. The invention has the following advantages that: (1) labor is saved, and the cost is reduced. Steps, such as ploughing, ridging, top application, intertillage and weeding, are dispensed with, and compared with the prior conventional labor-livestock operation, five labors can be saved each 667m2 (i.e. 1acre) of flue-cured tobaccos, so that the production cost is reduced; (2) the growth and development of tobacco plants and the yield and quality of tobacco leaves are not affected; (3) the operation is simple, and the popularization is easy. The invention is applicable to the cultivation of flue-cured tobaccos.

Description

Technical field [0001] The invention belongs to a flue-cured tobacco cultivation method. Background technique [0002] Flue-cured tobacco is an important economic crop in my country, with an annual planting area of ​​more than 1 million hectares. At present, the cultivation of flue-cured tobacco mainly adopts ridge cultivation, the ridge height is generally 0.25~0.3m, the ridge spacing is 1.0~1.2m, the plant spacing is 0.5~0.6m, every 667m 2 (1 mu) about 1100 tobacco plants. The whole process of flue-cured tobacco cultivation mainly includes seedling raising, plowing the land, ridging, fertilizing, transplanting, preventing and controlling diseases and insects, topping and wiping, harvesting and baking, graded delivery, etc. The entire process requires a lot of labor and labor intensity. Because flue-cured tobacco is mainly distributed in mountainous regions such as southwest my country, the production process is relatively low in mechanization. Currently, 667m is grown through ...

AI Technical Summary

Problems solved by technology

[0003] There are many cultivation measures and methods in the production of flue-cured tobacco, such as plastic film mulching, double-layer fertilization, etc., and the patented technology is: No. 200810069035.5 "Film-mulching Cultivation Model of Flue-cured Tobacco Concave Double Ridge Full Growth Period", which is mainly aimed at To improve the yield and quality of tobacco leaves; there is also No. 2009101092852.0 "A Method for Misplaced Cultivation of Flue-cured Tobacco in One Ridge and Two Rows", which is mainly aimed at improving the quality of tobacco leaves, highlighting the characteristics of tobacco leaf divisions, and making full use of land resources in tobacco areas; these technologies have little effect on labor saving. obvious
