Embodiment

[0015] In a flue-cured tobacco cultivation site, the planting of flue-cured tobacco→green manure-red sweet potato→green manure-cure-cured tobacco is carried out in rotation.

[0016] Fertilize the tobacco field when cultivating flue-cured tobacco in the first year, and the mass ratio of nitrogen, phosphorus, and potassium nutrients in the applied fertilizer is 1:1.5:2.5; then ridges are formed, the height of the ridge is 0.25m, and the distance between the ridges is 1.0m; then the distance is fixed. Cultivation, control the flue-cured tobacco plant spacing to 0.55m; plow the soil of the tobacco field after harvesting the tobacco leaves, sow and plant green manure in the winter of the year, and the amount of green manure seeds is 3.5kg / 667m 2 (mu), the basic seedling density per mu is 70,000 to 100,000 plants; it is planted by sowing or drilling, in which 15-20 kg of superphosphate and plant ash are used as base fertilizer, and 15-20 kg of general calcium is used as top dressing...

Abstract

The invention discloses a rotation method for increasing the quality of tobacco leaves. The method is as follows: in the March of the first year, tobacco fields are fertilized and ridged, and tobacco is planted according to fixed spacing; after tobacco leaves are harvested, the soil of the tobacco fields is ploughed, and in the winter of the same year, seeds are sowed and green manure is planted; in the March of the second year, the soil is ploughed, green manure is planted, ipomoea batatas are planted, and in winter afterwards, green manure continues to be planted; in the March of the third year, the soil is ploughed, the green manure crop is cradled and then directly buried in the soil for 'green manuring', and tobacco is planted; and tobacco, green manure, ipomoea batatas, green manure and tobacco are rotated repeatedly. The rotation method has the following advantages: (1) the efficiency of tobacco field rotation is increased, the environment of the tobacco fields is improved, and diseases, insect pests and weeds are reduced for tobacco; (2) green manuring and ipomoea batata growing improve the physical and chemical properties of the soil, regulate the soil fertility, and increase the quality of tobacco leaves. The rotation method is suitable for tobacco growing.

Description

technical field [0001] The invention relates to planting, in particular to a method for cultivating flue-cured tobacco. Background technique [0002] Flue-cured tobacco is one of the important economic crops, and my country's planting area and total output rank first in the world. Due to the limitations of climate and cultivation conditions in production practice, coupled with traditional farming methods, large-scale continuous cropping of flue-cured tobacco in tobacco-friendly areas often leads to aggravation of soil-borne diseases in tobacco fields and a decline in tobacco planting benefits; after many years of continuous cropping, soil nutrients for tobacco planting are not balanced. Sexual enrichment and depletion seriously affect the quality of tobacco leaves. This has become an important factor limiting the production of flue-cured tobacco, directly affecting the local economic development. Reasonable crop rotation can effectively reduce the impact of continuous crop...
