Oatmeal has seeds. The optimum germination temperature of oilseed is 15-20 ℃. When the temperature is higher than 25 ℃ or lower than 8 ℃, the seeds will not germinate. In winter, you need to plant oil and wheat vegetables in the greenhouse to ensure the germination rate, and in summer, you need to prevent the seedlings from being sunburned by the direct sun during the day. The demand for fertilizer and water is relatively large. In the most vigorous growth period, fertilizer and water should be applied according to the growth status of oilseed and soil. 1、 Does oilseed have seeds? Oilseed has seeds. Most of them grow from seeds. The fertilizer demand of oil wheat vegetables is relatively large. In order to grow oilseed and wheat vegetables better, it is necessary to apply compound fertilizer dominated by nitrogen fertilizer. It is also necessary to pay attention to the change of temperature and do a good job of shading and thermal insulation. 2、 How to plant oilseed 1. Select improved varieties: only seeds with good quality can ensure the germination rate and the quality of oilseed, so the step of seed selection is essential. At this stage, it is necessary to screen out all withered or false seeds.
2. Soaking and sprouting: the seeds of oilseed lettuce are relatively thick. There are two ways to whiten the seeds. First, soak the seeds in clean water for 3-4 hours, wrap them with gauze, and then refrigerate them in the refrigerator for 10-15 hours. Second, soak the seeds in clean water for 4.5-5.5 hours. Then wrap the seeds with wet gauze and promote germination in a cool place. Pay attention to the humidity of gauze.
3. Seeding and seedling raising: select fertile soil with good drainage and air permeability to sow germinated seeds. After mixing the seeds with sand, they shall be evenly sown on the soil. It is necessary to ensure that there is a certain spacing between the seeds. Then cover the seeds with a thin layer of soil and pour enough water to ensure the growth of the seeds. After the seedlings grow stably, they can be colonized. （YouMaiCaiYouChongZiMa）
