The root vegetables are rooted in the underground roots, and have a firm texture and good quality. They are suitable for stir-frying or pickling. 1. Variety selection: It is mainly of common species and giant horses. The common species of rutabaga is a little smaller root ball, with tender meat, less fiber, fragrant and brittle, and good quality. Malong has small, dense green leaves and a large rootball with a yield of more than 5,000 kg/mu. 2. Suitable timing for sowing: This area can be planted from late July to late August and can be broadcast directly or transplanted. 3, a reasonable close planting: live broadcast, the general species left about 25,000 acres; transplanting density 25cm15cm, acres planted about 20,000; Ma Long species transplanting density 45cm50cm, acres planted about 3,000. 4. Management of fertilizer and water: After the kohlrabi is transplanted and planted, it is necessary to immediately cast live tree fertilizer. During the growth and development of kohlrabi, it is necessary to diligently apply thin high-quality organic fertilizer and complete NPK fertilizer. Usually every 15-20 days once, even 3 to 5 times, each time with NPK fertilizer 5-10 kg per acre, with thin human fecal urine with water fertilization. In the rapid expansion of underground roots, Mushi monopotassium dihydrogen phosphate is applied in an amount of 3 to 5 kilograms, and once every 7 to 10 days, a vegetable-specific organic humic acid active liquid fertilizer or 500 times of plant vitality is sprayed at 800 times, 5000 times. Huangjia Natural Brassica Mixed Liquid and other sprays are sprayed 3 to 5 times; and ensure that there is sufficient supply of water evenly, avoid frequent cracking and soil cracking. 5, pest control: seedling stage to pay attention to control of aphids and virus diseases, can be sprayed on the foliar spray 1 ~ 2 times 2,500 times the net, 800 times the virus A mixture for prevention and treatment. During the expansion period, we must pay attention to controlling yellow peony root rot and root rot, etc. We can spray 1500 times of agricultural land music and 2500 times of hymexazol mixture for prevention and treatment. The kohlrabi is mainly sold as pickled products. To expand production, it is necessary to join hands with processing companies to create higher profits. China Agricultural Network Editor
