Due to the development of planting technology, Youmai vegetable can be planted all year round, but the better sowing period is generally in early April to mid-July. Oil wheat vegetable planting method:1. Land selection and farming oil wheat vegetables can be planted all year round, strong adaptability to the soil and environment. Choose a plot of land with deep fertile soil, convenient drainage and irrigation, deep plowing about 20 centimeters to increase the permeability of the soil. After drying and sterilizing, apply well-rotted farmyard manure, mix thoroughly, and level and harrow.2. Before sowing, water enough to keep the soil moist. After soaking high-quality seeds, sow them by sowing and cover them with 1-2 cm of dry soil. When the temperature is low, it needs to be covered with plastic film to keep warm and moist to promote the seeds to germinate as soon as possible.3. Planting DensityThe film should be removed after the seedlings grow, wait for 6 days, dig planting holes according to the rigid planting distance of 20x15, and set the transplanting value. When transplanting, it is best to choose a sunny day after rain or a sunny evening. After planting, check the seedlings to make up for deficiencies and cultivate strong seedlings.4. Water and fertilizer management Oil wheat vegetables should be fertilized in time during the growing period, and the first fertilizer application should be carried out after transplanting and planting. When the seedlings grow to 20cm, with diluted phosphate and potash fertilizer for the second fertilizer, 15-20 days before harvest with diluted urea to promote the last growth. Watering should be carried out in time after fertilization to ensure soil moisture. Things to keep in mind when planting oleander Seed germination out of the soil usually takes about 5-7 days. If you want to speed up the germination of the seeds, you can accelerate the germination of the seeds before sowing. First you can soak the seeds in warm water at 40-45°C for a while, then put the seeds in a cool place and wait until the seeds of oleander turn white before you can plant them. If you want to accelerate the growth of oleander, you can also control the ambient temperature between 20-25 ℃, and then open the window every morning and evening to ventilate, which can promote the growth of oleander.
