Efficient cultivation method of intercropping flue-cured tobacco and soybeans

Abstract

The invention discloses an efficient cultivation method of intercropping flue-cured tobacco and soybeans. The efficient cultivation method includes the following steps that (1) base fertilizer is applied in furrows before ridging in a tobacco field; (2) soil preparation and ridging are carried out on the tobacco field in good time; (3) the whole ridges are covered with a mulching film; (4) two rows of shaft well type transplanting holes are formed in the two sides of each ridge top, and two rows of crop planting holes are formed in the zone between the two rows of shaft well type transplanting holes; (5) flue-cured tobacco is transplanted in a shaft well mode, and tobacco plant transplanting position is located over the base fertilizer applied in furrows; (6) while the flue-cured tobacco is transplanted, soybeans are sown in a dibbled mode in the two rows of crop planting holes; (7) the flue-cured tobacco and the soybeans are managed through the normal method in the following steps. The influence on flue-cured tobacco growth by spring drought in the southwest region, the nicotine content of the flue-cured tobacco on the upper portion is reduced remarkably, the potassium content of the flue-cured tobacco on the upper portion is obviously increased, richness and diversity of rhizosphere soil bacterial communities of the tobacco plants are remarkably improved, flue-cured tobacco successive cropping obstacle is overcome, the income of peasants is increased additionally, and the efficient cultivation method is particularly suitable for the southwest region in China.

Description

technical field [0001] The invention relates to a high-efficiency cultivation method for flue-cured tobacco and soybean intercropping, and belongs to the technical field of flue-cured tobacco planting. Background technique [0002] To the southwest of my country, flue-cured tobacco is an important economic crop. The applicant found that the following problems currently exist in the flue-cured tobacco planting process: [0003] 1. The problem of spring drought. Spring droughts often occur in Southwest China, which will affect the normal growth and development of flue-cured tobacco and the quality of flue-cured tobacco in severe cases. At present, more watering is mainly used to solve the spring drought, which will cause a substantial increase in production costs. [0004] 2. Flue-cured tobacco has the problem of high nicotine content in the upper part. The nicotine content is one of the most important indicators to determine the availability of flue-cured tobacco leaves. ...

Problems solved by technology

At present, more watering is mainly used to solve the spring drought, which will cause a significant increase in production costs

[0004] 2. Flue-cured tobacco has the problem of high nicotine content in the upper part

At present, there are measures to increase the potassium content of the upper tobacco leaves: there is a method of directly injecting potassium-containing reagents into the tobacco plants to increase the potassium content of the upper tobacco leaves; there is also a way to increase the potassium content of the tobacco leaves through grafting; another method is to use nitrogen fertilizers, potassium fertilizers or Bio-organic fertilizers and other methods to increase the potassium content of tobacco leaves, all of which will increase the production cost of flue-cured tobacco

[0006] 4. Barriers to continuous cropping of flue-cured tobacco

However, there are often problems of one kind or another due to the selected interplanting crops and interplanting modes, and these interplantings cannot solve the above problems well
