Seedling roots are underdeveloped, weak in absorption, and often fall in high temperatures due to drought. Therefore, it is necessary to supply enough water in a timely manner to keep the water from pouring and promote root growth. When the broken heart is topdressed, each time the seedlings are combined with cultivator, and top dressing is applied to raise seedlings. The rosette period is the time when Chinese cabbage grows rapidly. In this period, water and fertilizer management must be strengthened to promote plant growth. After Dingmiao or after plant rejuvenation, should be in the interline or between the strains open hole or small ditch fertilization, per acre topdressing compound fertilizer 20 kilograms or ammonium sulfate 20 kilograms, top dressing after pouring a permeable, after depending on the soil dry and wet conditions for watering . The nodule period is the period when Chinese cabbage products are formed. It requires a large amount of fertilizer and water, water and fertilizer management during the ball stage, and focuses on the beginning and the middle period of the ball-making process, ie, “suction bowl fertilizer†and “heart filling fertilizerâ€. Speed ​​fertilizer, and must be applied in advance, immediately after the start of the center of the dressing, the application of ammonium sulfate 15 ~ 20 kg per acre, after the plant pumping cylinder topdressing once, combined with irrigation after top dressing, irrigation method to slow the water Slow irrigation is good. Irrigation should be stopped 10 days before harvest to prevent the ball from being too resistant to storage due to excessive water content. Manual Hydraulic Operating Table
