Efficient multiplication of cabbage in shallow water

The planting area of ​​shallow water sluice in Qinshui County has reached 60,000 mu, but it can only be produced once a year, and the land utilization rate is low. In recent years, we have promoted the cultivation mode of shallow springs and spliced ​​spring cabbage, making full use of winter land, and the benefits have doubled. From the end of April to the beginning of May, Shallow bracts will be planted and harvested from October to November. Spring cabbage will be planted on October 5-15 and will be transplanted from late November to early December and harvested at the end of April of the following year.

Shallow sluice choose sandy soil with fertile soil and convenient irrigation and drainage. Dehydrated organic fertilizer 2000 kilograms per mu, compound fertilizer 40 to 50 kilograms. After the ploughing, the leveling and smashing are done, and 3 to 5 cm shallow water is to be planted. Seedlings require complete apical buds, which are thick, thin, and thick and have two or more complete knots. Large red purple and Elian 4 can be used. The temperature rose to above 15°C in the spring and colonized when the temperature was 10cm above 12°C. For the early-maturing varieties, the row spacing is 1.6-1.8 meters, and the hole spacing is 0.7-0.8 meters. Each hole is planted with 1 branch or 2 branches. The middle and late-maturing varieties were selected and the spacing was 1.8-2 meters and the distance was 1 meter. The water level is maintained at 3 to 5 cm in the early growth period and 6 to 7 cm after emergence of the floating leaves. When there are 2 to 3 vertical leaves, it rises to 10 cm. After that, the air temperature rises and the height of the plant gradually deepens to 20 cm. It cannot exceed 30 cm. . After the emergence of the leaves, the field water will fall to 10 centimeters, the deepest not more than 20 centimeters, to promote scab. When there is a small amount of vertical leaves, a fertilizer is applied, and 1,000 to 1,500 kilograms of urea or 15 kilograms of urea per acre is applied to promote the growth of vertical leaves. When the leaves of some plants appeared, 20-25 kg of urea and 15 kg of potassium sulfate were applied per acre. Insect pests generally occur lighter, sporadically occurring mainly include spoilage diseases, brown spot diseases, etc., and comprehensive measures are taken by adopting agricultural measures such as disinfection of seed crops, addition of organic fertilizers, control of nitrogen fertilizer application, application of phosphorus and potassium fertilizers, and agricultural control and chemical control. Prevention.

Cabbage is selected from high-yield, high-quality, early-maturing, and strong winter varieties such as Chunfeng 007. 15 days before sowing, 2,000 kg per acre was used to make glutinous manure. Plowing and hoeing were used to mix soil fertilizer. Before the planting, the seedbed was made into a 1.5-meter-wide sorghum. The ratio of seedbeds to Daejeon was 1:15. The amount of seeds per acre field is 20-50 grams. Spreading, drilling can be, it is best to use nutrition or plug seedlings. Pay attention to control underground pests. Appropriate amount of water after emergence. 3 to 4 leaf shallow loose soil once to promote root growth and development at the same time seedlings. Timely colonization, colonization prematurely prone to premature convulsions, colonization too late seedlings too late to occur new roots, in case of low temperature susceptible to freezing. Before planting, 2000 mu of organic fertilizer was applied per mu, and 40 kg of compound fertilizer was 45%. Before winter, strictly control the amount of fertilizer. After the temperature rose in the spring, the cultivators timely weeded and weeded. The lotus stage applies 15 kg of urea per acre. In the early stage of the ball, 25 kg of urea was applied per mu. Fertilizing outside the root of the ball during the ball stage is conducive to high yield. After the ball is tightly consolidated, the market will be harvested in time. Pests and diseases mainly include black rot, soft rot, downy mildew, aphids, cabbage caterpillars, etc., and they should be treated with drugs in time according to the occurrence.
