Oily wheat is a kind of vegetable that has both food and medicine. It has many aliases, such as bitter vegetables, succulent grass, and no parsley. The oily wheat can be fried or cold, with a bitter taste and can clear away heat, detoxification, anti-inflammatory, eyesight and so on. Oilseed rape is sold in all major supermarkets and markets. The following small series to introduce the cultivation techniques of oil wheat. Oily wheat can be sown in all seasons. The general sowing season is from August to September. The northern winter weather is cold, so it can be cultivated in greenhouses. First, land preparation and land preparation Before the selection, the plots of the long-lasting herbicides such as Puschte and Beansulfuron were not planted. The land was deeply irrigated before planting, and about 3,000 kg of farmyard manure per 667 m2, 10-15 kg of urea and 15 kg of 20 kg of diammonium phosphate. 5-10 kg of potassium sulphate or 50-60 kg of compound fertilizer, and spread the ground. Mix the fertilizer with the soil and make a flat or stilt with a width of 1.5-2 meters and a length of 10-20 meters. Second, nursery 1 sowing time: can be arranged in batches and marketed in batches. Spring protected field cultivation can be planted in the greenhouse in late March, or planted in the greenhouse in the hotbed; or planted in the middle and late April in the hot bed; spring open field cultivation can be planted in mid-May in mid-July; Cultivation can be sown in late July and early August. 2 sowing seedling: nursery application of appropriate amount of decomposed organic fertilizer watering. Because the seeds are brown and small, they must be mixed with fine soil before sowing, spread, and covered with a layer of mulch after sowing. After the emergence, the mulch is removed, and after 5-7 days, the seedlings are emerged. When the seedlings grow to 3-4 leaves, You can transplant Honda. Germination method: soak the seeds in water for 5-6 hours, dry them slightly, wrap them in a damp cloth and germination in a cool place, and sown when about 3/4 seeds are white. 3 The soil in the seedling stage should be kept moist, and it should be shaded during the summer exposure. When the true leaves are 3 to 4 pieces, they are planted in the potting soil of the base fertilizer. The plant spacing is about 10~15 cm and the water is poured. It can be managed normally after about 1 week. 4 Planting density: a suitable yield can be obtained by close planting, and the plant spacing is 15×15cm, and 667-30,000 plants can be transplanted per 667m2. Third, daily management 1 The pests and diseases are small, the growth is fast, and the amount of fertilizer is large. Generally, the fertilized organic fertilizer mainly based on nitrogen fertilizer is sprayed once every 7 to 1 day to promote the growth of the leaves, and the fertilization should be stopped one week before harvesting. 2 Hi cool, slightly cold and not heat resistant, the leaf growth temperature is 11 ~ 18 ° C, too high temperature will affect growth or early flowering. 3 Hi moist, need to give plenty of water during the vigorous growth period, usually watering once a day, if necessary, watering early and late to avoid affecting the quality of the leaves. 4 After harvesting, the wounds should be dried to apply one time of decomposing organic fertilizer to promote the germination of new leaves, which can be harvested again after a period of time. Fourth, pest control Oily wheat is prone to downy mildew, and it is controlled by 72% metalaxyl Mn-Zn wettable powder 400-500 times liquid spray or 72% Plex 1000 times liquid spray at the beginning of the disease. When there is damage to the leaf miner, it can be sprayed with 1% fly larvae 1500 times liquid. V. harvest Harvesting can be started about one month after planting or from about 15 leaves, usually in the morning, and the green leaves that are fully grown, thick and crisp can be handcuffed down, generally up to 2000- per 667 m2. 3000kg. Sixth, nutritional value The oily wheat has the characteristics of low calorie and high nutrition. The nutritional value is slightly higher than lettuce and far superior to lettuce, which has the effects of lowering cholesterol, clearing the lungs and so on. The above is the cultivation of oil wheat vegetables and pest control techniques, the content is for reference only. Soil conditions and climatic conditions vary from region to region, so adjustments should be made during planting.
