Chaotian pepper cultivation techniques

1. Do the trick in time: In late October to early November, build a scaffold and dig a good film. In mid-to-late February, the film will be roasted for 20-30 days. 1 mu of land needs 12-15 square meters of seedlings pool, built 5-6 meters wide middle arch shed. Nursery crickets should be built in areas where drainage and irrigation are convenient, leeward and sunny, and no solanaceous crops have been planted within three years. The disease-free and fertile soil was used as bed soil and 0.25 kg of potassium dihydrogen phosphate and 0.5 kg of compound fertilizer were applied per 10 m2.

2, germination sowing: seed drying before seedlings 2-3 days, and then stored in a ventilated place, before sowing with 50-55 °C water sterilization 15-20 minutes, and then 20-30 °C water soaking 12-24 hours, with The gauze wraps the seeds and puts germination at 28-30°C for 75 hours. It can be sown when the soil temperature reaches 8°C or above in mid-to-late March. Watering with a watering can before sowing, after the water is immersed, the seeds of the buds will be evenly sprinkled in the pods. Seeds of 100-120 grams per 100 square meters will be sown, and 8-10 millimeters of fine soil will be covered with a sieve and then drenched. 800-1000 times the aqueous solution of carbendazim, covered with a white plastic film after water infiltration.

3, seedbed management: Early attention to insulation and cold, covered with straw curtain at night to keep warm, or in the shed buckle small arch shed, four feet around the feet hanging high double membrane insulation, late heat during the day and timely release. When the seedlings are weak, the seedbeds can be filled with increasing amounts of water. 2 leaf 1 heart period and 4 leaf 1 heart during the seedling 2 times, leaving 1 tree per 3.3 square centimeters, combined with the seedlings to remove weeds. 10-15 days before transplanting, the membrane was exfoliated and the seedlings were irrigated. One and two days before the seedling emergence, they were poured once. When plant height 15-20 cm, 8-10 leaves can be transplanted.

4, planting seedling technology: fertilization before planting. May 15-20 transplanting. Fertilized land large transplanting density should be thin, small trees should be dense, each planting two points, 25 cm from the point, 6000 points per acre, 12,000 seedlings. When transplanting, use a drill or a stick to punch the membrane along the rows of the plant. After watering, plant the seedlings, and use the soil to tightly seal the membrane holes so as to avoid running through the air. Plastic film covers an area of ​​60-80 yuan more investment, more than 30% more than conventional cultivation. The mulching land should be covered with oysters, and the plot should not be selected from the plots where the atrazine herbicide was used before, the base fertilizer should be applied, the sorghum should be 80-85 cm wide, and the 90-100 cm wide mulch should be used (preferably Black film), transplanted after filming.

5, field management: after planting often check the film, found damaged or blown by the wind, timely sealing soil. After the seedlings are plucked, they are tipped in time to grasp the principle of not playing lean, not fighting, not playing, and not playing. Remove the weeds in the eyes and in the ditch, and apply fertilizer and water in a timely manner. After the emergence of the main stem, after the collateral blossom, 1 quick-acting fertilizer should be applied, water should be poured for 2 times, and pest control should be done well. Harvest 1-2 days before frost.
