How to cultivate oil wheat vegetables? The taste of the oily wheat vegetables is slightly different from that of the lettuce leaves. The edible oil wheat vegetables are mainly eaten with the young shoots and young leaves. So how to grow oily wheat can achieve high yield? Here, Hui Nong.com will bring you a simple study of the high-yield planting techniques of oilseed rape. 1. Growth characteristics of oil wheat The germination conditions of the oilseed rape seed are not high. Generally, the germination condition can be successfully germinated above 4 °C. If the temperature is between 15 and 20 °C, the oil wheat seed can only be germinated in 3 to 4 days. If the temperature exceeds 30 °C, the oil wheat Vegetable seeds will not germinate. The most suitable temperature for oilseed rape seedlings is 12-20 °C. If the temperature exceeds 24 °C during the daytime, the temperature at night is also above 19 °C, which may easily lead to uncooked convulsions. 2. Seedbed preparation Before the selection of the seedbed, there were no long-lasting herbicides such as Pu Shite, Bean Sulfate, high-potential, high-water-preserving and fertilizer-preserving plots, and more organic fertilizers. The seedbeds per acre were 15-20 square meters. 3. Seed treatment The oilseed rape seedlings should be soaked and germinated. The seeds should be wrapped in gauze and then immersed in cold water for about 1 hour. Then they should be picked up at 15-20 °C or placed in the refrigerator of the household refrigerator for 2-3 days. After the seeds are white, they can be sown. 4. Sowing time 4.1 Summer broadcast From April to June, the seedlings are exposed in the open field, and the high potential is selected. The 2 meters is connected to the ditch, and the deep-flooding and fertilizing fertilizer is used to build the flattening. Soak seeds for 3 hours, wait until the seeds are dry and sow. The seedling bed is poured into the foot water, the seeds are spread on the surface of the clams, and the seed mud is covered, and the water is poured. In case of high temperature and drought, the sunshade net is covered on the coffin. After the seedlings are opened, the nets in the seedling bed should be moderate and should not be dried. . 4.2 Autumn broadcast From July to September, the seedlings in the shed are immersed in the germination. The method is to soak the seeds with gauze and soak them for 3 to 4 hours, then take them out into the refrigerator for 10 to 15 hours, and 75% of them can be sown. It is best to use small arch sheds or greenhouses for autumn sowing seedlings. Pay attention to soil moisture after emergence. Do not over-dry and remove weeds in time to ensure smooth drainage. 4.3 spring broadcast From January to March, nursery in the shed, 2 sheds in the standard shed, 1 ditch in the middle, deep shovel, pouring the bottom water, seeds spread in the sputum, covering the seed mud, covering the seedless, flat plastic film Generally, the seedlings are emerged in 10 to 15 days, and the seedlings grow longer after the rainy weather. After the seedlings are removed, the mulch film is removed, and the air is ventilated. During the day, it is necessary to prevent high temperature injury and damage to the frost at night. 5. Method sowing When planting, mix the appropriate amount of fine sand with the seeds, separate the seeds, and then spread the seedlings. Do not spread the seedlings to prevent the seedlings from growing. Cover the seeds with a 0.5 cm thick mixture of phoxim and cover the sun and rain. 6. Seedling management The seedlings of the oily wheat cultivar grow two leaves of true leaves, and the transplant density is 6×6 cm. The seedbed of the oily wheat must be kept moist and shaded at noon. At the same time, oilseed rape should pay attention to pest control during the seedling stage. 7. Site preparation Before the planting of the oil wheat, the organic fertilizer is 3500-4000 kg, the phosphate fertilizer is 20-25 kg, the nitrogen fertilizer is 40-50 kg, the potassium fertilizer is 10-15 kg, the 畦 width is 1～1.5 m, the plant spacing is 10×10-15 cm, and the planting is 10×10 cm. 4 to 50,000 plants. 8. Interplanting weeding After planting the sauerkraut, the seedlings are applied with a small amount of quick-acting nitrogen fertilizer in combination with watering for 1 or 2 times. Generally, 5 kg of urea or ammonium sulphate is applied per acre to promote the growth of the plant, and the soil should be kept moist and cultivated in time. 9. Timely shed The oily wheat cultivar is fast-growing leafy vegetables. The suitable growth temperature is 18-25 °C. When the night temperature is lower than 12 °C, the shed should be buckled. After the shed, the shed temperature and the relative humidity in the shed should be adjusted in time. The relative temperature in the shed is less than 90. % is appropriate. 10. Reasonable topdressing The cultivation of oilseed rape should be kept clean and hygienic, and 0.3% potassium dihydrogen phosphate and urea solution should be used for foliar spraying for 3 to 4 times in the early and middle growth period. The whole season is topdressed 2 to 3 times, 5 to 10 kg of urea per acre or 10 kg of ammonium sulfate. 11. Harvest at the right time When the number of leaves of wheat vegetables reaches 30-34, the plant height is 45-48 cm, and the degree of development is 60-69 cm, it can be harvested once at a distance of 2 to 3 cm from the ground. After harvesting, the old leaves and diseased leaves are removed. Timely supply of the winter market.
