Example Embodiment

[0081] Example 1

[0082] Rotate flue-cured tobacco and garlic for cultivation:

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

[0084] Garlic is first planted on the yellow soil, and after the garlic grows until the garlic stalks are extracted, the planted soil is renovated after the garlic stalks are harvested, and then flue-cured tobacco is planted on the renovated soil. The depth of the refurbishment is 25cm, and the soil blocks on the surface of the refurbished soil are knocked and flattened, and within 15 cm of depth from the surface to the ground, the particle size of the soil particles is less than 1cm;

[0085] At the same time, spray compound fertilizer with 60% ammonia nitrogen content and 40% nitrate nitrogen content as base fertilizer on the surface of the renovated soil, spray 30kg per mu, and then plant flue-cured tobacco.

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

[0087] The yield of tobacco ...

[0088] Example 2

[0089] Interplanting flue-cured tobacco and garlic:

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

[0091] Methods as below:

[0092] a. When planting garlic on October 10 of that year, reserve a flue-cured tobacco planting row next to the garlic planting row, and plant flue-cured tobacco in the reserved flue-cured tobacco planting row on May 3 of the following year; every three rows of garlic will be planted with an empty row. The planting density of flue-cured tobacco is: row spacing 35cm and plant spacing 15cm; the planting density of flue-cured tobacco: row spacing is 115cm, plant spacing is 65cm;

[0093] b. After the garlic matures on May 28 of the following year, harvest the garlic, apply the special compound base fertilizer for flue-cured tobacco to the garlic-growing field, and apply 55kg of special compound fertilizer base fertilizer for each acre; then directly renovate the soil where the garlic has been planted to the adjacent On ...

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.
