First, line pepper planting technology and management
1, seedling raising
(1) Preparation of seedbed: Prepare nutrient soil with 5:2 pond mud and decomposed organic fertilizer, then add 600-800 times of carbendazim, and finally cover with film 1-2 days for disinfection.
(2) Seed treatment: before sowing, the seeds are dried in the sun for 1-2 days, then soaked in 10% trisodium phosphate solution for about 20 minutes, taken out and washed, soaked for 6-8 hours, and finally put in an environment of 28-30 DEG C to accelerate germination. When the seeds turn white, they can be sown.
(3) Sowing: Before sowing 1-2 days, water the seedbed with water from the soles of feet. When sowing, the seeds are evenly mixed with fine sand, sprinkled on the seedbed, covered with a layer of soil with a thickness of 0.5- 1cm, and finally covered with straw, and watered with appropriate amount of water.
(4) When more than 70% of the seeds emerge, the mulch is removed.
(5) If the seedlings have caps, manually pull them out, and spray 0.2% compound fertilizer+potassium dihydrogen phosphate solution, and then spray 0.3-0.4% compound fertilizer+potassium dihydrogen phosphate solution after two real leaves grow. Generally, it is applied 4-6 times at seedling stage.
(6) Uncovering the film about 7 days before planting and hardening the seedlings, and completely uncovering the film about 2-3 days before planting.
2. Transplanting and planting
(1) Requirements for transplanting field: The soil layer is deep, the soil is loose and fertile, and the irrigation and drainage performance is good. No solanaceous crops have been planted within 3 years.
(2) Transplanting in the field: 2000 kg of decomposed organic fertilizer, 50 kg of calcium superphosphate, 25 kg of potassium sulfate and 2 kg of borax are applied per mu.
(3) Planting time: Generally, planting will be carried out about 35-40 days after sowing, when the seedlings will grow 6-8 leaves.
(4) Density: planting in spring, with 2500-3000 plants per mu, with a row spacing of 50cm and a plant spacing of 45cm. Planting in autumn, planting 3000-3500 plants per mu, with row spacing of 50 cm and plant spacing of 35 cm.
Step 3 manage
(1) After planting, apply diluted human manure 1000 kg per mu.
(2) After budding, apply 600kg of human excrement and urine per mu or dilute it with15kg ammonium sulfate to 5% solution.
(3) At the full fruit stage, apply ternary compound fertilizer 15kg or human excrement 1000kg per mu.
(4) At the beginning of August, 800kg (20% concentration) of human excrement and urine was applied to each mu of land.
(5) At flowering stage, 0. 1-0.2% borax solution can be applied.
Second, what is the average yield per mu of line pepper?
1, the yield per mu of linear pepper has a great relationship with varieties and management techniques.
2. Excellent super-long pepper, with a fruit length of about 30cm, a fruit diameter of about 1.8cm and a single fruit weight of 25g. In the plots with high fertility, the yield is as high as 5000 kg.
3. Supreme pepper, the fruit length is about 28cm, the fruit diameter is about 2cm, the single fruit weighs 30g, and the yield per mu is about 4500kg.
4. Dachangjinjiao, the fruit length is about 26cm, the fruit diameter is about 1.6cm, the weight of a single fruit is 20g, and the yield per mu is about 3500kg.
5. Pepper king, the fruit length is about 23cm, the fruit diameter is about 1.4cm, the weight of a single fruit is 20g, and the yield per mu is about 3500kg.
6. Wang Changchang, the fruit length is about 30cm, the fruit diameter is 1.5-2cm, the weight of single fruit is 35g, and the yield per mu of high water and fertilizer plots is about 4500kg.
