List:
1: firstly, water the pot soil, mix the seeds with fine soil and scatter them on the soil surface. Just cover the seeds with a little soil, not too thick, and spray the topsoil to keep them moist. Generally, germination takes about 3-4 days, and it takes about 1 week when the temperature is low. You can also use the on-demand method, 2-3 capsules per hole, with a spacing of about 3-5 cm. The time interval can be shorter when the temperature is high and slightly longer when the temperature is low.
2. Keep the soil moist at seedling stage, and water it 1 time in the morning and evening when the temperature is high. After 2 weeks of germination, spray 1 diluted decomposed organic fertilizer with water.
3: 4-5 real leaves can be transplanted and planted, and the plant spacing depends on the size of the variety, generally around 15-20 cm. Watering after planting, slightly shading, and normal management after survival. If transplanting is not needed, it is necessary to start thinning seedlings and leave larger seedlings. The principle of thinning seedlings is to make the distribution of seedlings more uniform, and rows can be selected many times until the spacing is appropriate. Topdressing 1 times decomposed organic fertilizer after each thinning.
4. Advantages of slow food in May: Slow rape plants in May are stout, with a plant height of 25-30 cm and a spreading degree of about 30 cm. The leaves are upside down, green and smooth. Petiole is white-green, flat and thick. There is a layer of wax powder on the surface of leaves and petioles. Early maturity, high yield, strong cold tolerance and difficult bolting in early spring. This variety has wide adaptability and can be planted in many forms. It can be planted in spring and autumn, but it is mainly planted in spring. Generally, it is planted in Xiangyang plot at 5438+ 10 in early June, planted in the open air in mid-March and harvested in late April.
