Pay attention to the key points of Pepper planting Management in early Spring

Capsicum planting

Sowing time selection: sowing in the middle of February, planting in the middle of April, planting 30g / mu. Sow 10 grams of pepper seeds per square meter seedbed, 5 square meters per mu. The preparation of nutritious soil follows the principles of no pollution, no diseases and insect pests, rich nutrition, loose air permeability, and can be well mixed with 1 beat 3 roasted sieve soil, 1 peat 3 rotten pig manure and 1 pound 3 saprotic soil. The seeds were dried for 2-3 days, then soaked in 55 ℃ warm water for 15 minutes, washed with clean water, and germinated for 5-8 days under the condition of 25 ℃-30 ℃. About 70% of the pepper seeds could be sown when they broke their mouths. Mix the pepper seeds with plant ash or dry sand or fine soil, sow on the seedling ground, pay attention to sparse sowing, cover and sterilize the sifted fine soil 1mm, sprinkle a thin layer of seed water, cover the ground with thin film, and build an arch shed to enter the seedling stage management.

Seedling stage management: temperature management: the temperature was kept at 20 ℃ ~ 30 ℃ in daytime and about 13 ℃ ~ 18 ℃ at night, which was high in front and low in later. Divide the seedlings in time, when the seedlings are 30-35 days old and 3-4 true leaves, the distance between seedlings is 7-8 cm. A sunshade net should be built on a small arch shed on a sunny day. Seedling bed management: slow seedling stage, ensure ground temperature up to 18 ℃ ~ 20 ℃, daily temperature 25 ℃, strengthen mulching, increase air relative humidity. Pepper seedling diseases and insect pests mainly control quenching disease and blight, found a small number of diseased plants, timely pull out, with 75% "chlorothalonil" (tetrachloro phthalonitrile) 600 times solution, once every 7 to 10 days, spray twice.

Seven days before planting, the seedling was tempered, the night temperature dropped to 13 ℃ ~ 15 ℃, the moisture was controlled, and the ventilation rate was gradually increased. Planting site selection: continuous cropping of hot pepper should be avoided, so fields that have not planted Solanaceae crops in 3 to 5 years, rich in organic matter, deep soil layer, water and fertilizer conservation, irrigation and drainage, no water accumulation in rainy season and no water shortage in drought should be selected. Generally, the best planting period is 50-60 days after sowing and 8-10 true leaves of seedlings. Apply enough high-quality base fertilizer, applying farm manure 3000kg to 4000kg per mu. In order to improve the fertilizer effect, the base fertilizer will be concentrated in holes or furrows, not dispersed in the whole field. Fertilization should not be too shallow or too deep, and it is better to apply fertilizer at 10-15 cm. Make border film, border height 10 cm 20 cm, border width 100 cm 120 cm. When the soil temperature at the depth of 10 cm in the plough layer reaches 10 ℃ ~ 20 ℃, it can be planted. Pay attention to crop rotation. 50 kilograms of quicklime can be used for disinfection per mu. One or two days before planting, the seedlings were sprayed with dimethoate (thiophosphate) 1500 times and chlorothalonil 500 times to avoid carrying aphids and pouring thin rotten human feces and urine. Planting should be carried out in cloudy or sunny afternoon, with as much soil as possible, less root damage, and improve the survival rate. The planting specification is 1.3 meters, the plant spacing is 30 cm, the row spacing is 50 cm, about 3300 million pepper plants are planted per mu, and the fixed roots are watered thoroughly.
