Kale, also known as green leafy cabbage, is one of the specialty vegetables in China. Kale is warm and heat resistant and has a strong adaptability to the soil. However, the heat tolerance of different varieties of kale is different, and the planting time is also different. The following Hui Nong network Xiaobian will tell you about the knowledge of kale planting. First, the choice of variety There are three main varieties of kale, including early, middle and late varieties. The time of each variety planting and the time of harvest are different. Early-maturing varieties: generally grown around August, harvested around October. Medium-bred varieties: generally grown in November, and received in January of the second year. Late-maturing varieties: generally grown in December and harvested in March of the second year. Planters can choose to grow canola varieties according to local environmental conditions. Second, soil selection The loose and fertile soil of Chinese kale, which contains many organic soils and excellent drainage and irrigation conditions, is more suitable for canola growth. But in the choice of soil for kale, it is best not to choose to plant it. That is to say, the vegetables that have been planted in the cruciferous family before, it is best not to plant them now, and it is easy to have diseases. Third, soil preparation, upper base fertilizer After the land is selected, it is necessary to prepare the land. The whole land is generally deep-turned and then disinfected with lime. Flatten the ground. The kind of kale is generally adopted by ridge planting, so that drainage is more convenient. At the same time, it is necessary to put a good base fertilizer, generally on the farmyard manure, about 8,000 kg of farmyard manure on an acre of land. Fourth, planting, density control A variety of kale, different varieties of planting time is not the same. For example, early maturing varieties, there are two ways of planting, one is live broadcast, one is transplanted. When raising seedlings, use a sunshade net to cover it, so that the kale is good. Planting should not be too thick, nor too thin. For precocious varieties, the trees retained in one mu of land are below 6,000. Among the mature and late-maturing varieties, the trees retained in one mu of land are below 5,000. Five, watering, fertilizer When kale grows the first true leaf in the seedling stage, it is necessary to apply fertilizer, 2 kg of compound fertilizer and 4 kg of urea on an acre of land. During this period, the soil should be kept moist and there should be no water shortage. Slow seedling period: the soil should be kept moist and watered sooner or later. Growing season: 6 kg of compound fertilizer per acre, 12 kg of urea. In the growth process of Chinese kale, there are strict requirements for water and fertilizer, which can be used in small amounts, which is beneficial to the growth of kale. At the same time, we must do a good job of weeding. Generally, after the cabbage is half a month after planting, it is necessary to loosen the soil. When you form a vegetable meal, you have to cultivate it. 6. Prevention and control of pests and diseases 1. The straw of the upper crop should be treated thoroughly. 2. Disinfect the seeds before planting the kale. 3. Generally use insecticidal lamps to trap insects. 4. Finally, use pesticides to kill pests. Seven, harvest When the mustard is harvested, it should be harvested in time. It is usually harvested in the morning on a sunny day. The harvest was late and the taste was poor. Harvesting is early and production will be reduced. The standard for kale harvesting is that the height of the rapeseed is the same as the height of the leaves, and the flower buds are not yet flowering, so you can harvest them at this time. The above is the key point of the cultivation method of kale in the small series compiled by Huinong. Nowadays, it is the planting time of the late-maturing varieties of Chinese kale. In addition to the above-mentioned planting management, the kale growers should also pay attention to the occurrence of freezing damage.
