Cotton intercropping is an effective measure to increase the replantation index and increase production efficiency. Weixian County has an annual cotton planting area of ​​about 600,000 mu, including 200,000 mu of cotton intercropping. Intercropping patterns include cotton-watermelon, cotton-onion, cotton-potato, cotton-jujube. In order to continuously improve the production efficiency of cotton fields, in recent years, with the help of the Provincial Academy of Agricultural Sciences, we have actively explored the efficient production of cotton and screened a number of good production models. Among them, the cotton-white radish intercropping pattern average yield per mu radish 4000 More than kilograms of cotton, the average cotton production of 80 kilograms of cotton, in 2003 the benefits of more than 2,000 yuan per mu, more than 900 yuan per mu than pure cotton, and less investment, easy management, has been widely welcomed by the masses. The techniques are summarized as follows: 1. Variety Selection White radish is selected from about 60 days of growth period, and is suitable for spring-grown varieties such as Changchun Dagen; cotton is resistant to pests and diseases, such as noxious 566 and GK. 12, SGK321 and so on. Second, the cultivation model Cotton radish intercropping with 1 to 2-style belt planting, each planting a row of cotton, 2 rows of radish, bandwidth 1.1 meters. 3. Soil fertility for soil preparation and fertility selection. Water source conditions are good. No plots for radish have been planted in 2 years. Mushi roasted organic fertilizers are 4,000 to 5,000 kilograms, diammonium hydrogen phosphate is 20 to 30 kilograms, and potassium sulfate is 10 to 15 kilograms. The land was ridged, ploughed, and ridged. The ridge width was 0.7 meters and the ridge height was 0.15-0.2 meters. Fourth, sowing white radish appropriate sowing date for the April 5 to 10, sowing on both sides of the ridge, spacing 0.5 meters, spacing 0.25 meters, density 4850 strains / acre, and then cover the mulch on the ridge surface. The suitable sowing date for cotton is from April 10 to 20, planted in the center of the ridge with a spacing of 1.1 meters, a spacing of 0.2 meters, and a density of 3000 plants/mu. 5. Fertilizer and Water Management Radish Rosette Period, Mushi 5 kg of urea, applied on the membrane, then watered, so that the fertilizer dissolved in water with water infiltration; radish swelling application of urea 10 kg, potassium sulfate 10 kg, applicator Water on the membrane. Stop watering about 7 days before harvest. After the harvest, the radish broke the film and watered, and applied 10 kg of urea to promote cotton buds and flowering growth. Six, radish harvest in early June, radish grows to 0.5 kilograms can be harvested according to market demand early, otherwise the impact of cotton growth and gradually increased, the latest can not exceed June 15. Seven, cotton management radish harvested, cotton management with a single cotton.
