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. ...

Examples

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0030] The high-efficiency cultivation method for flue-cured soybean intercropping comprises the following steps:

[0031] (1) Apply basal fertilizer before the tobacco field is ridged;

[0032] (2) Tobacco field should be ridged at the right time, the top of the ridge is slightly flat, the height of the ridge body is 25-30cm, and the width of the bottom of the ridge is 180-250cm;

[0033] (3) Cover the entire ridge with plastic film;

[0034] (4) Set up two rows of well cellar-type transplanting holes on both sides of the ridge top, with a row spacing of 130-140 cm and a hole spacing of 50-55 cm. Then open two rows of crop planting holes, and the distance between the crop planting holes and the adjacent rows of pit-type transplanting holes is 0.4-0.45 cm;

[0035] (5) Flue-cured tobacco is transplanted in...
