3. Cultivation of oil vegetable

Oil vegetable is propagated by sowing. The seeds are small and hard, generally sown in spring, but also in summer, and the suitable germination temperature of seeds is generally above 23 ℃. Before sowing, the soil should be deeply ploughed, finely plowed, leveled and fertilized, and then the seeds should be mixed with fine soil and sown without covering the soil. The emergence time varies with temperature, humidity and depth. For early emergence, it is best to take seedbed seedlings. When the seedling grows to more than 15 cm, it begins to have a stimulating function, so when transplanting or planting, you should wear canvas or rubber gloves, and wear rubber shoes to avoid skin exposure. After the new shoots grow around the old plants, as the new shoots grow, the old stems on the upper part wither one after another and need to be divided. Dividing time can be carried out in winter and spring. The whole plant is dug up, the buds are cut off, and then planted around the garden at a plant spacing of 20 cm. It can play a protective role in that year, and even chickens will not dare to enter in the second year. In order to avoid affecting the growth and management of the main crops, the elongated branches and leaves can be cut off in a planned way, and the stems of the grass can also be blocked with wooden sticks.
