Embodiment 1

[0057] The light, simple and efficient cultivation method of flue-cured tobacco in the tobacco-rice rotation area of ​​the present embodiment, its planting process is as follows:

[0058] 1. Deep turning and drying:

[0059] After the harvest of the previous crop rice, plow and sun-dry in time, the plowing depth is 20cm, and the sun-drying time is 3 months, and it becomes a sun-dried field;

[0060] 2. Floating nursery:

[0061] ⑴. Floating seedling pond arrangement: 7 days before sowing flue-cured tobacco seeds, spread black agricultural film on the bottom of the floating seedling pond to prevent leakage, spread 4cm thick river sand on the film, and then pour floating seedling nutrient solution into the floating seedling pond until 10cm deep water level;

[0062] (2) Floating Seedling Sowing: On December 10, the flue-cured tobacco seeds were sown into the seedling hole of the floating seedling tray equipped with the seedling substrate, and then the seedling tray was placed ...

Abstract

The invention discloses a simple and high-efficiency cultivation method for flue cured tobaccos in a tobacco-rice rotation area, and relates to the technical field of commercial crop cultivation. The cultivation method comprises S1. deep ploughing and upturned soil drying in the sun; S2. floating-seeding comprising floating-seeding pond management, seeding of floating-breeding, seeding control, and hardening seedling through sand culture; S3. tobacco field management comprising tobacco field ridging, cavity opening comprising plant cavity opening and fertilizing cavity opening, and fertilizing; S4. tobacco seeding transplantation; S5. mulch covering comprising mulch covering, mulch hole opening, and mulch breaking; S6. diseases and pests prevention; S7. bud inhibition; and S8. other management. The simple and high-efficiency cultivation method is labor saving, high in quality and high in efficiency, can be used for large scale production of flue-cured tobaccos in tobacco-rice rotation areas, and suitable for cultivating flue-cured tobaccos in large tobacco-rice rotation areas in south of the Yangtze River in a simple and high efficiency mode.

Description

technical field [0001] The invention relates to the technical field of economic crop cultivation, in particular to a light, simple and high-efficiency cultivation method for flue-cured tobacco in a tobacco-rice rotation area. Background technique [0002] With the rapid development of urbanization in the past 10 years and the decline in the comparative benefits of tobacco planting, the team of tobacco farmers and the scale of planting have undergone significant changes. The team of tobacco farmers in production areas has gradually decreased. At the same time, the scale of flue-cured tobacco planting has gradually expanded. The average household size has gradually developed from the traditional 3-5 mu to the current average household area of ​​about 50 mu in all production areas, and the number of growers with hundreds of mu also accounts for a large proportion. With the rapid expansion of the average household size and the continuous increase of labor costs, the cost of flue...
