No-tillage rotation method of flue-cured tobacco and grass

Abstract

The invention discloses a method for no-tillage crop rotation of flue-cured tobaccos and pastures. The method uses excellent gramineous pasture pennisetum hydridum and flue-cured tobacco for no-tillage crop rotation and comprises the detailed steps of: ridging during the first year when planting flue-cured tobaccos, and leaving the tobacco sticks on the tobacco ground to protect the ridge body after harvesting the tobacco leaves; clearing up the tobacco sticks and weeds after spring comes in the second year, then planting the pennisetum hydridum of which the planting density is the same as the planting density of the flue-cured tobacco, and leaving the residues of the pennisetum hydridum in the ridge body after harvesting the pennisetum hydridum completely, and protecting the ridge body; using phytocide to control the growth of the weeds after spring comes and before the tobacco is planted in the third year, digging the ridge when planting tobaccos, fertilizing, and planting tobaccos; clearing up the ridge surface, removing the weeds, covering the ground by a ground membrane when the soil moisture content is enough so as to promote normal growth of the flue-cured tobacco, and repeatedly performing alternant planting of flue-cured tobacco -> pennisetum hydridum -> flue-cured tobacco in this way. The method has the advantages of: increasing the crop rotation efficiency of the flue-cured tobacco, increasing the quality of the tobacco leaves, saving the steps of turning over of the soil, ridging, topdressing, intertillage, weeding and the like, saving six workers every 667 square meters of flue-cured tobacco, reducing the production cost, and being simple to operate and easy to popularize.

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, and the annual planting area in my country is more than 1 million hectares. At present, the proportion of flue-cured tobacco crop rotation is small, while continuous cropping is common. This has led to the aggravation of soil-borne diseases in tobacco fields and the decline of tobacco planting benefits. The main reason why flue-cured tobacco continuous cropping is common is that there is no crop with high economic benefits and simple planting technology in the flue-cured tobacco farming system. The traditional flue-cured tobacco and corn rotation is not popular with tobacco farmers because of the low economic benefits of planting corn. In addition, the cultivation process of flue-cured tobacco is complex, labor-intensive, and labor-intensive. In addition, the degree of mechanization of flue-cured tobacco p...

Problems solved by technology

But the used stevia rebaudiana of this method also has the requirement of its growth environment, and its main use is as medicinal material, and consumption is limited

There are also reports that planting tobacco directly on the original ridge where flue-cured tobacco was planted in the previous year can save the land plowing process, but this involves continuous cropping of flue-cured tobacco, and continuous cropping of flue-cured tobacco will lead to aggravation of flue-cured tobacco diseases, affecting the yield and quality of tobacco leaves
