Key Cultivation Techniques for Intercropping Chili Peppers and Cotton

Chili-cotton intercropping techniques

1. Cropping schedule

Chili peppers are grown in greenhouses with insulation for seedlings in mid-November, transplanted to the field in late March, and harvesting begins in mid-April; cotton is grown in nutrient pots for seedlings in late March and transplanted in late April.

2. Technical points

(1) Early-maturing, short-stalked chili varieties such as Xiangyan No. 6 and Guanjun are used, while E-zamian cotton is selected for cotton.

(2) The bed width is generally 1.6 m, with 2 rows of chili peppers planted in the bed at a plant spacing of 0.3 m and a density of about 2,780 plants per mu, and 1 row of cotton planted on each side of the bed. Cotton wide row 0.9 m, narrow row 0.7 m, plant spacing 0.45 m, density 1,850 plants per mu.

3. Yield

The average lint cotton yield is more than 80 kg per mu, and the chili pepper yield is more than 4,000 kg.

4. Suitable areas

This model is suitable for promotion in suburban areas and cotton regions with convenient transportation.
