Potato-tobacco rotation planting method for planting tobaccos in potato ridges

Abstract

The invention relates to a potato-tobacco rotation planting method for planting tobaccos in potato ridges. The method is characterized in that sweet potatoes and tobaccos are transplanted on formed sweet potato ridges in a mode of two ridges of sweet potatoes, two ridges of tobaccos, two ridges of sweet potatoes and two ridges of tobaccos, the sweet potatoes are transplanted in an equidistant planting mode, and the tobaccos are transplanted in a triangular final singling planting mode; the sweet potatoes and the tobaccos are managed according to a conventional cultivation method after being transplanted, the sweet potatoes are harvested in mid-to-early August, and after the sweet potatoes are harvested, soil in a sweet potato planting area is used for earthing up roots of the tobaccos; the tobaccos are harvested and baked in batches in September of the same year; after the sweet potatoes are harvested, the original sweet potato planting place is vacated, and tobacco leaf harvesting operation is facilitated; and during planting in the next year, on the same land parcel, land preparation, fertilization and ridging are conducted again, and the sweet potatoes and the tobaccos are planted in a field ridge exchanging manner. The sweet potatoes and the tobaccos are in the same position in the potato-tobacco rotation mode, the soil structure can be improved, the space resources of the land are fully utilized, harvesting machinery can enter and exit conveniently, the utilization efficiency of light energy is improved, and the purpose of increasing yield and value is achieved.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to an intercropping method for planting tobacco "potato tobacco" in potato ridges. Background technique [0002] Tobacco is an important economic crop in our country, which has made great contributions to our country's taxation and local revenue. In recent years, due to the continuous reduction of tobacco planting area and driven by economic interests, continuous tobacco cropping has become a common phenomenon. Tobacco is a non-continuous crop. Long-term continuous cropping will destroy the balance of soil nutrients, cause soil compaction, and damage the soil ecological environment and microbial communities, which is not conducive to the sustainable development of tobacco. How to integrate tobacco production into large-scale agriculture and achieve sustainable development is an urgent problem that my country's tobacco industry needs to solve. [0003] Sweet potato is the fou...

Problems solved by technology

The conventional crop rotation planting mode between tobacco and potato is to directly transplant sweet potatoes in the furrows of two ridges of tobacco. Sweet potato plays a secondary role in the planting mode of planting rotation between tobacco and potato, and the conventional planting mode of planting rotation between tobacco and potato does not have the support of agricultural machinery. Very inconvenient to operate
