Embodiment 1

[0082] To grow flue-cured tobacco and garlic in rotation:

[0083] The method of field plot test, the plot area is 5.5m×5.4m=29.7m 2 .

[0084]Garlic is first planted on the yellow soil land, and the garlic shoots are drawn out after the garlic grows. After the garlic shoots are harvested, the planted soil is refurbished, and then flue-cured tobacco is planted on the refurbished soil. The depth of the refurbishment is 25cm, and the soil clods on the surface of the refurbished soil are finely leveled, and the particle diameters of the soil particles are all less than 1cm from the surface to the depth of 15 cm in the ground;

[0085] At the same time, the compound fertilizer with 60% ammonia nitrogen content and 40% nitrate nitrogen content was sprayed on the surface of the refurbished soil as a base fertilizer, spraying 30kg per mu, and then planting flue-cured tobacco.

[0086] The planting density of flue-cured tobacco was 30 cm between rows and 10 cm between plants.

Embodiment 2

[0089] Interplanting flue-cured tobacco and garlic:

[0090] The method of field plot test, the plot area is 5.5m×5.4m=29.7m 2 .

[0091] Methods as below:

[0092] a. When garlic is planted on October 10 of the current year, a flue-cured tobacco planting row will be reserved next to the garlic planting row, and flue-cured tobacco will be planted in the reserved flue-cured tobacco planting row on May 3 of the next year; every three rows of garlic are empty for planting flue-cured tobacco and garlic. The planting density of flue-cured tobacco is: the row spacing is 115cm, the plant spacing is 65cm;

[0093] b. On May 28 of the next year, after the garlic is mature, harvest the garlic, and apply a special compound base fertilizer for flue-cured tobacco to the field where the garlic is planted, and apply 55kg of compound base fertilizer for flue-cured tobacco per mu; then directly renovate the soil where the garlic has been planted to the adjacent Plant the flue-cured tobacco ...

Abstract

The invention relates to the technical field of tobacco plantation, and specifically relates to a planting method for relieving continuous cropping obstacle of tobacco plantation soil; the method comprises planting tobacco in association with garlic; the quality of the plantation soil can be maintained for a long time by planting tobacco in association with garlic, thereby maintaining the productivity of the land. By planting tobacco in association with garlic, not only the production efficiency of the land is increased, but also the yield and quality of the tobacco are increased. Meanwhile, a certain leaf area index can be kept in the field by the associated plantation, thus being able to sufficiently utilizing the light energy, space and time, thereby increasing the annual total output. The provided plantation mode achieves anniversary production of the land, increases the land utilization ratio and the yield.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco planting, in particular to a planting method for alleviating continuous cropping obstacles in tobacco planting soil. Background technique [0002] Planting several crops on a piece of land according to a certain row, plant spacing and width ratio of land occupation is called intercropping. Generally, several crops sown at the same time are called intercropping, and those sown at different times are called intercropping. Intercropping is the traditional experience of farmers in our country, and it is a measure to increase production in agriculture. Intercropping intercropping can rationally allocate crop groups, make crops tall and short in layers, and alternate rows, which is conducive to improving the ventilation and light transmission conditions of crops, increasing the utilization rate of light energy, and giving full play to the yield-increasing effect of side row advantages.
