Cultivation techniques of Colored Pepper

Choose a good seed. The first generation of hybrids with large fruit shape, good quality and strong disease resistance were selected with 2000 grains per 667m.

Cultivate disease-free and strong seedlings. Do a good job of seedbed disinfection and seed disinfection, soak the seeds with 10% trisodium phosphate for 30 minutes, rinse and then soak the seeds to accelerate germination, preferably with 128-hole holes. Summer and autumn seedlings should be covered with sunshade net at noon, and the tuyere should be installed with insect control net to prevent virus disease. before planting, 1-2 times Ⅱ and 3-4 potassium dihydrogen phosphate should be sprayed to prevent excessive growth, aging and the occurrence of weak seedlings.

Fertilization, soil preparation and planting. Select the protected ground that has not planted eggplant fruit crops in the previous three years, clean up the plant residues and weeds in the previous crop, and apply more than 4000 kg of rotten heat, high quality fine organic fertilizer every 667m 2. Ploughed and turned three times to reach the standard of leveling and crushing. It is formed into a small high border with a width of 50 cm and a height of 18 cm, with a row spacing of 100 cm and a plant spacing of 40 cm. It can also be planted in large and small rows, with an average row spacing of 75-100cm and a plant spacing of 40cm, with 1600-2000 plants per 667m.

Prune and leave the pepper. Each plant leaves two main branches, remove the lateral buds, remove 3-4 buds at the base of the door in time, and leave pepper from the fifth section. The lateral bud of the middle branch can retain pepper properly and take the top after leaving 3-4 leaves. Leave 7 main branches per square meter, do not need to cultivate the soil, when the plant height is 50 cm, use the rope to hang the main branch, the plant height can reach more than 2 meters, each plant bears pepper about 20.

Management measures: (1) watering. Watering to slow down the seedlings after planting, and then ploughing to preserve soil moisture to promote root growth. After the fruiting period, water it according to the season and weather and keep it moist. It is best to install drip irrigation, buckle plastic film, drip 1-2 times a day. (2) topdressing. Biological chicken manure was applied every 10-20 days, 80-100 kg per 667 m 2, or 15-20 kg of ternary compound fertilizer, and potassium dihydrogen phosphate was sprayed on the leaves once in 7-10 days. (3) adjust the temperature and shade. The optimum temperature is 25 ℃-30 ℃ in daytime and 15 ℃-23 ℃ at night.

Pest control. The main results are as follows: (1) the tea yellow mite should be sprayed with 2500 times solution of Zongmike or 2000 times solution of Uranus. (2) virus disease, once the infection has a great impact on the yield, mainly to prevent, after the disease, the diseased plant is removed and buried deeply. (3) for epidemic diseases and crop rotation, the roots were irrigated with 500-fold solution of disinfectant alum.
