After joining the WTO, the internationalization of the vegetable market has become irreversible. With the increasingly fierce competition in the vegetable market, the development of green, pollution-free vegetables has become an inevitable trend. Only the development of green, pollution-free vegetables can be brought in line with international standards, so that our vegetable industry can be invincible. The development of green, pollution-free vegetables will, on the one hand, provide urban and rural residents with vegetables that meet hygiene standards, and on the other hand will not have a bad influence on the environment. By optimizing cultivation measures, reducing chemical fertilizers and pesticides, reducing nitrate content and pesticide residues, effectively controlling diseases and pests, and producing nutritious, safe and pollution-free products, after several years of production practices and investigations, the following cultivation points are proposed: 1 Strict selection of vegetable gardens. The vegetable garden should have a good ecological environment. Air, water, and soil should be free of pollution. Try to avoid the industrial area and the traffic arteries, or choose the city, industrial area, and the main entrance of the traffic arteries. At the same time, the soil is loose and rich in organic matter. 2, select good disease-resistant varieties. The selection of good varieties with strong resistance to diseases, diseases and insect pests, and high yield and high quality is an effective measure to reduce field use and reduce pesticide pollution. Such as Zhongjiao No. 4 and Zhongjiao No. 8. 3, to cultivate disease-free strong seedlings. Seed treatment before sowing, soaking with trisodium phosphate or potassium permanganate, or seed dressing with carbendazim, hot-water boiled seeds, killing the bacteria on the seeds, disinfecting bed soil, avoiding disease upload, and rationally preparing nutrition Soil, expand nutritional areas, strengthen seedling management, and promote seedling growth. 4, rotation down. Continuous cropping, on the one hand, results in the proliferation of pests and weeds. On the other hand, excessive consumption of certain elements in the soil is not conducive to the use of land for cultivation, resulting in a reduction in production. Therefore, we must pay attention to crop rotation, promote grain and vegetable rotations, and implement non-solanum vegetables for more than three years of rotation. 5, a reasonable fertilization. Each mus of cooked and quality harmless farmyard fertilizer 5000kg, pave the way for plowing. Then apply 50 kg of NPK fertilizer or 5 kg of urea, 15 kg of diammonium phosphate and 15 kg of potassium sulfate. 6, large ridge double film green pepper. Deeply turn 20cm to make a 1.2-meter-wide ridge, open a ditch in the middle of the ridge, and cover with a mulch. When the 10cm ground temperature is stable above 15°C, planting can be done. When planting, sunny day afternoons should be selected. Large ridges and double rows are to be used, and the inner tight outer pines are to be planted. Holes are punched by a hole puncher with a small row spacing of 50cm. The hole distance is 40cm, about 3500 holes per acre. After the hole is punched, 2 soil-burrowed earthworms will be planted into the hole, and then the warm water will be poured until the warm water infiltrates. 7, field management. After pouring the slow seedling water, it is necessary to timely cultivate the furrows and raise the ground temperature. After the seedlings are slowed to bloom, they are generally not watered, and only pour small water in the drought. When the door pepper grows to the red jujube size, combined with cultivator fertilization, 10 tons of human fecal urine is fermented and fermented per acre, and urea is 10 kg. After the soil is cultivated, it is watered. After harvesting the peppers, they should be watered in time in order to promote the fruit, but it is necessary to prevent the accumulation of stagnant water. After the hot summer rain, it is necessary to rinse the well with water in time to reduce the soil temperature and ensure the normal physiological metabolism of the root system. In the hot season, it is necessary to pour small water sooner or later. When the temperature is higher than 30°C, small water should be poured at night to reduce the temperature of the soil. 8, pay attention to flood control and flood protection. After the sweet pepper enters the full fruit period, the root absorption weakens gradually and it is not resistant to waterlogging. At this time, the rainy season in the north and the high temperature season, the sudden and sudden rain has a great influence on sweet peppers, and it is easy to induce a variety of diseases. Therefore, when the drought occurs, the water will be gently sloping and the water will be drained in time. Maintaining the proper soil temperature will promote the healthy growth of green peppers. . 9, suitable for harvesting. When the peel becomes green, the fruit is firm and the skin is bright, it can be harvested. It usually takes about 20 days from flowering to harvesting. 10. Comprehensive control of pests and diseases. According to the law of the occurrence of pests and diseases, combined with weather forecasting, it will be based on prevention, focusing on the promotion of physical and biological control. If it is really necessary to use chemical agents, they should use high-efficiency, low-toxicity agents that do not harm humans and animals. To achieve symptomatic, timely, limited, rotating, strictly control the safety interval. China Agricultural Network Editor
