Problems solved by technology

The conventional tobacco-potato intercropping and tobacco-bean intercropping planting mode is to transplant sweet potatoes and beans in the furrows of two ridges of tobacco. Sweet potatoes and beans are in a secondary position in the intercropping planting mode, and conventional tobacco-potato intercropping The mode is not supported by agricultural machinery, and the operation is extremely inconvenient

Embodiment 1

[0038] Tobacco monoculture: the ridge distance is 140cm, the ridge height is 30cm, the tobacco adopts equidistant planting mode, and the plant spacing is 65cm; it is managed according to the conventional cultivation method.

Embodiment 2

[0040] Monocropping sweet potato: the ridge spacing is 90cm, the ridge height is 25cm, and the sweet potato adopts the equidistant planting mode, and the plant spacing is 28cm; it is managed according to the conventional cultivation method.

Embodiment 3

[0042] Flue-cured tobacco-sweet potato-mung bean intercropping planting (detailed method as mentioned above): ridge distance is 140cm, ridge height is 30cm, transplant tobacco and sweet potato according to the mode of two ridges of tobacco, two ridges of sweet potato, two ridges of tobacco, two ridges of sweet potato, each tobacco Plant two rows of sweet potatoes on the ridge, and finally two rows of tobacco and four rows of sweet potatoes. After the sweet potatoes are harvested, level the land and sow mung beans (row sowing). , the spacing between sweet potatoes in the same row of sweet potatoes is 25-30cm, the row spacing of two rows of sweet potatoes in the same tobacco ridge is 40cm, the row spacing of two rows of sweet potatoes in adjacent tobacco ridges is 100cm, and the spacing of mung beans in the same row of mung beans is 15-20cm , the row spacing of adjacent mung beans is 50cm; tobacco, sweet potato and mung beans are managed according to conventional cultivation meth...

Abstract

The invention relates to a flue-cured tobacco-sweet potato-mung bean intercropping rotation planting method, which comprises the following steps: after fertilizing, ridging and film mulching, transplanting tobacco and sweet potato on the formed tobacco ridge according to a mode of two ridges of tobacco and two ridges of sweet potato, and transplanting the sweet potato and tobacco by adopting an equidistant planting mode; managing the tobacco and the sweet potatoes according to a conventional cultivation method after being transplanted, harvesting the sweet potatoes at the end of July, and after the sweet potatoes are harvested, leveling the and sowing mung beans; harvesting and baking the tobaccos in batches in late August in the same year; harvesting the mung beans in mid-early October in the same year; during planting in the next year, performing soil preparation, fertilization, ridging and film mulching again on the same land parcel, planting tobacco and sweet potatoes with field ridges exchanged, and sowing the mung beans after the sweet potatoes are harvested. By means of the method, the sweet potatoes can use tobacco ridging and film mulching machines, field operation is convenient, tobacco, the sweet potatoes and mung beans are matched in height, group ventilation and light transmission can be improved, the light energy utilization efficiency is improved, and the contradiction of land contention of tobacco grains can be effectively relieved through crop rotation, soil structure improvement and soil-borne disease reduction.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for planting flue-cured tobacco-sweet potato-mung bean intercropping. Background technique [0002] Tobacco is a non-continuous crop. However, due to the difficulty of planting flue-cured tobacco in rotation, most of the tobacco areas are dominated by single farming, and the phenomenon of continuous cropping in tobacco fields is more prominent. Long-term continuous cropping of flue-cured tobacco has caused problems such as biological monotony, one-sided consumption of soil nutrients, deterioration of plow layer structure, serious soil compaction, nutrient imbalance, accumulation of pathogens, and aggravation of pests and diseases year by year, which in turn leads to decline in tobacco leaf yield and quality. [0003] Sweet potato has the characteristics of high yield, strong stress resistance, wide adaptability, nutrient abundance and wide application, especially c...
