The autumn and winter cultivation of oil-grained vegetables is conducted, and seedlings are sown in October-December. In October, it was possible to plant seedlings in open fields, and in November and December, seedlings were planted in protective plots such as pipe sheds. The tube shed should be applied with basal fertilizer and plowed and ploughed. The 6-meter-wide tube shed should be 2 畦 or 3 畦. The seed bed should be sown with fine soil, the footing water should be poured every other day, and then sowing should be done. It can be used to grow about 3 mu in Daejeon. After sowing, it is sprinkled with a layer of nutritious soil to cover the seeds, and then a layer of plastic film or plastic film is flattened. Immediately after emergence, the flat-covered film was peeled off, the management was strengthened, and ventilation, ventilation, and warm-keeping work were performed.
1, colonization
Oil and wheat vegetables are transplanted. The phytosanedium should be applied to the phytofertilizer, and the general Mushi commodity organic fertilizer (including more than 40% of organic matter such as P2O5 and K2O6) should be 200-250 kg and the ammonium bicarbonate should be 50-60 kg. There are 5-6 true leaves of oil and wheat dish that can be planted. The spacing is about 20cm. In the middle of October and November, the oil and vegetable can still be transplanted on the ground. However, from late November to December, due to the winter time, it is necessary to The oil and wheat vegetables are transplanted into a plastic-covered pipe shed to prevent frost. The management method of planting is basically the same as that of lettuce. It is necessary to strengthen the management of fertilizer and water. It is necessary to maintain the water for eutrophication, and to prevent waterlogging due to excessive humidity, and to prevent and control pests and diseases. Diseases of oil-vegetables are mainly downy mildew disease, which can be controlled by carbendazim and glucomannan. The pests are mainly aphids and can be controlled by imidacloprid. After about 30-35 days of planting of autumn and winter oil and wheat vegetables, the yield per mu is about 1000-1500. kg.
2. Harvesting and listing
Under the conditions of market economy, oil and wheat dishes are harvested and marketed depending on the price. When it is difficult to sell vegetables, they can be marketed in small quantities. Normal plant heights of about 25cm can be harvested and listed. When the price of vegetables is good, some large stocks are listed and the plants can be left at 30-35cm to increase yield and increase yield. Because of the short time, little chemical industry, light pests and diseases, the economic benefits are relatively high.
