High-yield cultivation techniques of summer pepper
The cultivation of strong seedlings is highly selective. In the past two years, the plots of Solanaceae crops have not been planted, and the nursery sheds with low heights in the south have been built. The nursery shed south wall is 0.6 meters high. The north wall is 1.2 meters high and 1.5 meters wide. The length of the shed is determined by the area of ​​the field. Generally, 1/15 hectares of field sheds should be 5 meters long. Bed soil uses ripe soil within the tillage layer. 50 grams of diammonium phosphate per square meter of seedbed, mixed with soil and spread on the surface of the earth (disable urea, ammonium bicarbonate) before sowing, the seeds were soaked in warm water of 55°C for 15 minutes, and stirring constantly, the water temperature dropped. After soaking for 8 hours, remove the floating seeds. After soaking, remove the seeds and allow them to dry. The sowing date is about 80 days from the date of planting, and between about the beginning of spring and rain, 100 grams of 1/15 hectare of field crops will be planted. When sowing, pour water 1 times, sowing at least 3 times in order to ensure even seeding. Because about 10 centimeters from the south wall, the seedlings bred are weak seedlings. Therefore, 10 centimeters wide newspapers are needed to cover the 10 centimeters of the southern wall and not sow. Cover soil with fine soil, thickness of 4-5 mm. For ease of grasping, place a few chopsticks on the bed surface, and then cover the soil until the chopsticks are exposed. After covering the soil, cover the mulch, then cover the shed film and cover the grass. After 20 days or so, when the seedlings reached 50%, the mulch film was promptly removed. During the nursery period, every day after the sun comes out, it is revealed in time and covered before sunset. Choose windless, warm sunny days and use the noon to remove weeds. Seedlings need to be poured with small water, if necessary, can use Beijing-Jiujiang fertilizer tyrants, plant power 2003, potassium dihydrogen phosphate and other foliar fertilizers, the late seedlings need to ventilate the temperature and remove film hardening seedlings, planting two days before planting bed, Lee moved seedlings.

Colonization was selected for plots with high terrain and good summer flood control. Land preparation, ridge cultivation, ridge height 35 cm, ridge width 60 cm. It is planted in large and small rows with a small row spacing of 60 cm and a large row spacing of 80 cm. One-time application of base fertilizer before ridging, every 1/15 hectares of organic fertilizer applied 4000-5000 kg, 25 kg of ammonium phosphate, nitrogen, phosphorus, potassium ternary compound fertilizer 25 kg. At the end of the frost period (at the end of April), the weather was selected on a clear, warm and windless day and planted in plastic film. The two plants were planted with a spacing of 40 cm. Immediately after planting, water the plants and pour them 2 times. Afterwards, carry out the cultivating and raising the temperature so as to ease the seedlings.
About 20 days after planting in the growth period, peppers must be removed in time. Timely prevention of insects such as tobacco budworm, cotton bollworm, aphid, red spider, and tea plant. The tobacco budworms and cotton bollworms should be alternated with green kungfu, cymopharmacin, avermectin, and bauran, and used once every two days, and sprayed 5-6 times. Control aphids, use imidacloprid pesticides. Prevention of spider mites, tea amber selection of avermectin, broom net and so on. The diseases of hot pepper are mainly diseases and virus diseases. The key to preventing and controlling hot pepper diseases is the prevention of disease. Summer rainfall, in order to timely drainage, ridges can be digging gutters alternately several times. When diseased plants are found in the field, it is necessary to promptly spray Anke-Manganese Zinc, Redomer and other agents. The key to the prevention and control of viral diseases is the prevention and control of aphids. When a diseased plant occurs in the field, the virus is selected to be sprayed with a 500-fold solution and a suitable amount of foliar fertilizer is sprayed. In the summer, when the pepper grows vigorously, there is no need to water the year when the rainfall is heavy. In low rainfall years, it takes 3-4 times of water. When the fruit of the first layer is enlarged, 25 kg of compound fertilizer and 15 kg of urea are applied per 1/15 hectares, and after each 1 capsule of pods is harvested, watering and top dressing should be performed according to the growth conditions of the plants.
