Sunlight greenhouse cultivation of leeks in autumn and winter

The leek is delicious, rich in nutrition, and has a short growing period. It can be harvested several times at a time, and it can supply the annual market, especially the cultivation of autumn and winter leeches. The benefits are high. First, choose a good species: big leaf leek (Leaves leeks). Second, the preparation of fertilization: Cultivation of leeks to choose fertile soil land as well. The basal fertilizer is mainly organic fertilizer, and generally it is 3,000 to 4,000 kilograms per hectare of farmyard manure and 30 to 50 kilograms of compound fertilizer per 1/15 hectare. Spread the fertilizer evenly on the surface and plow it. Plow depth 15 cm. Then make it 1.8 to 2.0 meters wide flat or low. Third, timely sowing: solar greenhouse leek can be sown in early September to early October. After 45-60 days can be harvested. If new seeds are used, they should be subjected to low temperature treatment in advance, and they can be germinated by using the soil stratification method or directly placed in a refrigerator at 2-7°C. After 7-9 days, it can be broadcast on the seedbed. Because the leek seeds are small, the seeds should be mixed with 1-3 times the amount of sieving fine soil, so that after planting, the seeds are used to achieve seedling emergence. Seeds are generally 0.7-1.0 kg per 1/15 hectare. 3 to 4 days after sowing can emerge. Fourth, temperature control, humidity control, shading: leek hi cold and humid climate. According to the physiological characteristics of leeks, the greenhouse temperature should be controlled at 12-20 °C, the temperature exceeds 25 °C ventilation and cooling in time, to prevent the emergence of difficulties due to high temperature and drought. If the light is strong at noon, shady grass can be used properly. Watering should be lightly poured. Due to the 12-hour day light conditions, the leeks can still twitch and blossom when the temperature drops to 12°C. Therefore, with the gradual decrease of the temperature, in addition to proper ventilation at night, the grass pods should be covered early in the day. 5. Reasonably top-dressing: When the seedlings have two true leaves, the top-dressing will be carried out. Apply 100 kg of urea at a concentration of 0.3% per 1/15 hectares, and make a second top dressing 7-10 days before harvest. After each harvest 1 chase 1 fertilizer, the concentration of topdressing should also gradually increase, the entire growth period is generally top dressing 4-5 times. Sixth, timely control of pests and weeds: To remove weeds in combination with harvesting. The diseases and pests of leeks are mainly downy mildew and aphids. Downy mildew can be sprayed with 75% chlorothalonil wettable powder 600 times at the beginning of the disease. Aphids can be sprayed with 40% dimethoate 1500 times. VII. Scientific Harvest: Amaranth is harvested in several stages, and it is necessary to adopt large crops when harvesting. The leeks sown in early September can be harvested in 10 tablets and supplied to the market in early October. It can generally harvest 4-5 times, and it will be harvested by the end of March in the following year. Each 1/15 hectare can reach 2000-2500 kg. Seeds sown in early October will be harvested in about the middle of the 11th and will produce 1500-2000 kg per 1/15 hectare.
