The Cultivation and Management Techniques of Mustard Tuber in Winter and Spring Seasons
The pickled mustard is the main cash crop in winter and spring in Yinzhou, Ningbo. It has wide adaptability. Not only the cotton area can be planted, but also the north vegetable has been successfully moved southwards. The pickled mustard area is less, the hollow rate is low, and the quality is better than the cotton area. After three years of real production inspection, the average yield per mu can reach more than 3,000 kilograms, and the maximum per mu output is 4,286 kilograms, and the single largest is more than 0.5 kilograms. The efficiency is several times higher than that of rape and barley. The following describes the current technical advice on the cultivation and management of mustard in the winter and spring rice areas: After the mustard was transplanted, the climate in the early stage has been dry, resulting in slow growth and low yield. In response to these unfavorable factors, it is imperative to nurture and manage it. The first is to pay close attention to applying good winter fertilizer. It is required to use 25 kg of ammonium bicarbonate per acre plus 20 kg of superphosphate and 5 kg of potassium chloride to pour 25-30 lbs of water per mu. Help mustard leaves in the winter leaves color health, stable and long, to ensure safe winter mustard. The second is to re-inflate fertilizer. From February onwards, with the increase of temperature, the growing trend is strong, the expansion of mustard stalks is accelerated, and the demand for fertilizers is also increasing. In late February, heavy fertilizers are applied to ensure the expansion of tumor stems. Each mus of 25 kg of urea plus 12.5 kg of potassium chloride is poured into the water. 30 kg of compound fertilizer can also be used in the interline, and it is strictly prohibited to disperse nitrogen fertilizer alone, resulting in burning of leaves and tumor stems. After 10-15 days, according to the growth conditions, supplement balance fertilizer, 5 kg of urea per mu, plus 7.5 kg of potassium chloride, potassium chloride can also be applied alone to promote tumor stem enlargement consistent with the growth of the leaves, reduce the hollow, reduce the hollow index. During this period, it is best to spray the secondary EM fluid (or TD) to increase the yield significantly. The third is to prevent disease and disinfestation. As the humidity in spring fields is too large, black spot disease and white rust (pears commonly known as white fleas) are prone to occur. The agent can be used 500-800 times or 25% to 800-800 times mangosteen. Insect pests are mainly locusts, and can be used to control 10% of the net 10-20g plus 5% fipronil 2500 times.
