Management after Planting of Cold Cabbage Spring Cabbage
Cold Shed Cabbage is favored by vegetable farmers because of its low investment, high yield, early listing, and high yield. It is planted in every vegetable producing area in our province, and it is one of the more important vegetable species in the early spring vegetables. Right now, cold shed cabbage has just been planted. Here are some key points for management after planting. When cabbage is planted, the higher temperature is needed for the rapid seedling planting. The temperature in the cold house is controlled between 25°C and 28°C during the day and at least 10°C during the night to facilitate the rapid growth of its root system. Generally after three or five days, the seedlings can be reduced. After entering the seedling stage, the temperature should be appropriately lowered and maintained at 20°C-25°C during the day to control the amount of water and seedlings for about 10 days. Into the rosette period, according to the soil moisture and seedlings grow small water topdressing 15 kg of urea to promote the rapid growth of leaves. When entering the ball stage, the demand for phosphate fertilizer and potash fertilizer is greater, and the demand for water is also greater. For each acre, topdressing phosphorus and potash fertilizer is 20 kg. The field is good for dry seeing and wet, and it is not suitable for flooding. The temperature during the ball stage should not be too high, gradually increase the amount of air release according to the increase of outside air temperature, and the maximum during the day should not exceed 28°C. Care must be taken to prevent and control diseases during growth of cabbage. During the production period of Cold Shed Cabbage, due to the high humidity in the growing environment, two kinds of diseases, namely downy mildew and black rot, often occur. The downy mildew disease of cabbage is a yellow irregular polygonal lesion on the front of the leaves, with severe perforation. There is a layer of gray mold on the back. Generally in the mid-high temperature of the ball under the high-end environment, the choice of silver Faoli early in the disease prevention and control, continuous medication twice. Black rot is characterized by rotted root leaves, foul odor, and black patches, which can be sprayed twice with Wanjia. The harvest period of cold shed cabbage is generally from the end of April to the beginning of May. When the top of the leaf ball of cabbage is flattened, the leaves can be harvested by compaction. Early-maturing varieties generally have a single net weight of 1-1.5 kilograms. During harvesting, 2-3 old leaves are kept in the lower part of the leaf ball to protect the leaf ball, prevent extrusion and mechanical damage during transportation, and improve the commercial nature of the leaf ball.
