The origin of cauliflower is imported from China in the Qing Dynasty. It is rich in nutrients containing vitamin B, vitamin C, carotene and so on. Cauliflower is a semi-hardy vegetable. It is neither resistant to high temperature and drought, nor is it resistant to frost. The environment for growth and development is also strict. 1 , seeding seedlings On-demand seeding in nutrient mash during sowing, using nutrient é’µ seedlings. Cauliflower should be planted in a timely manner, and the best sowing period in the plains of the Yangtze and Yellow River basins is at the end of June. Seedlings can be emerged 3 to 4 days after sowing. Because the seedling period is in the hot and rainy season, the sunshade, rain and insect control are very important. In the first few days of emergence, shading measures should be taken, and the light transmittance should be gradually increased with the growth of the seedlings to prevent the seedlings from growing. After 10 days of seedling emergence, the shading net can be removed; when the seedlings are about 15 days old, the seedlings are Carry out seedlings, transplanting, weeding and covering soil to prevent lodging. Planting watering in combination with weather conditions, spraying pesticides and pest control. It is better to use shade nets and mesh to raise seedlings in conditions where conditions permit. 2, timely planting Mid-maturing varieties must be planted in time, otherwise it will cause "early flowers", "hairball" and other phenomena to make the flower ball lose its commodity value. When the seedlings grow to about 25 days of seedling age, they are colonized. Apply fertilizer to the ground before planting. The running level of 1.0m wide is convenient and drainage. It can also be made into sorghum with a height of 10~15cm, a width of 60~70cm, and a width of 30~40cm. When planting, it will apply 15KG of quick-acting nitrogen and phosphorus compound fertilizer. With soil hoeing to shorten the slow seedling time, root water should be poured immediately after planting. In order to avoid the sun exposure caused by baking, it should be planted after 3 pm, and the survival rate of cloudy planting is higher. The planting density is about 2600 per mu, and the row spacing is 40cm*50cm. 3. Adequate fertilizer and water in the early stage and pay attention to drought prevention and flood control Cauliflower is not afraid of water, so it cannot be dehydrated or flooded during the production process. When there is more rain in summer, the drainage in the field is guaranteed to be smooth, and watering should be done in time. After 3 days of planting, the seedling water was started to be poured. After the cultivating and watering alternately, the water is usually poured in 4 to 5 days without rain, and combined with watering for fertilization. In order to make the vegetative body grow quickly in a short time, the fertilization should be sufficient, and no seedlings should be used. These points are the key to the success of cauliflower cultivation. 4, the current ball before and after the control of water and fertilizer The flower ball of the cauliflower is particularly firm and brittle. If the water is too large when the ball is in use, the ball may expand too fast and some splitting may occur. The control of water and fertilizer before and after the ball can solve part of the splitting phenomenon. In addition, pest control should be strengthened at the initial stage of planting, and pesticides should be sprayed in time to prevent pests. 5. Pest control The autumn cauliflower has strong resistance and wide adaptability. There are no serious pests and diseases in the cultivation, and the prevention of pests and diseases is mainly in the production. The main pests are cabbage caterpillars, diamondback moths, and aphids. The specific control method is the same as the conventional control method. 6, harvesting In the first ten days of October, when the flower ball is fully grown, the flower buds are neatly tidy and can be harvested when the flower ball feels soft. It should be noted that the quality and yield of cauliflower harvested in the first ten days of October is the highest, generally harvested in the early morning and evening. In order to ensure the value of the ball of the ball, it is harvested every day. This is the autumn cauliflower cultivation technology. As one of the vegetables that can be eaten all year round, the market demand for autumn cauliflower is relatively large.
