I. Variety selection and appropriate sowing The general cauliflower varieties cannot be safely exposed in winter in the Xu-Huai area. After many years of introduction and trial planting, at present, we have screened out the suitable varieties of snow-covered wintering vegetables, Xueshan and Aoxue. Breeding period of about 330 days, generally from late July to early August seedlings, the best sowing date is July 20 to 30 days, mid-March to early April harvest. Each acre yields 2500 kg and the output value is 1500-2000 yuan.
Second, shading nets cover nursery nursery beds selected in the fertile loose energy discharge irrigation field, planting 1 acre field seedbeds need 30 square meters, seeds 40 grams. 30 kg of diammonium phosphate, 30 kg of urea, 15 kg of urea and 15 to 25 kg of high quality compost per 30 square meters of seedlings. Spread the fertilizer evenly on the surface of the seedlings, deepen the seedlings and make it 10 to 15 cm wide. 1 to 1.2 meters of glutinous rice noodles, irrigated with water, soaked immediately after the water sowing, cover seed thickness 0.5 cm. Take a small arch, cover the shade net from 10:00 to 16:00 on sunny days, and cover the rain with plastic film.
3. Apply base fertilizer timely planting deep-turning soil to re-apply organic fertilizer, increase application of phosphorus and potash fertilizer, and less nitrogenous fertilizer, apply 3,000 kg of decomposed organic fertilizer, 50 kg of compound fertilizer and 15 kg of potassium sulfate per mu, and when the seedlings are 5 to 6 Tablets are planted when true leaves (in mid-September). Before planting, the rice was further tilled and flattened to make a sorghum. The sorghum was 70 centimeters wide, and the row spacing was 55 centimeters. The spacing of the plants was 45 centimeters. About 2500 plants were planted per acre and watered immediately after planting.
Fourth, field management
1. The scientific management of fertilizer and water cauliflower hi humid environment, intolerance to drought, water requirements are more stringent. During the growing season, especially after the seedlings in the rosette stage and the flower bulb formation stage, sufficient water supply is required. The top-dressing fertilizer was dominated by nitrogen fertilizer, and phosphorus and potassium fertilizers were applied during the formation of flower bulbs. After 1 week of general easing, 1 to 15 kg of urea is applied per acre. In early November, control of fertilizer and water began to make the plants robust and enhance their ability to resist cold. In mid-December, winter is poured over the winter before wintering, and fertilization of soil over the winter, generally 15 to 20 kilograms of urea per acre topdressing, combined with watering to ensure that the outer leaves reach 18 to 22 before winter. In mid-February, the top dressing will be top dressing, 25 kg of urea, 15 kg of potassium sulfate or 25 kg of compound fertilizer. In the middle and late stages of growth, the outer leaves were covered and the flower balls were kept fresh.
2. Diseases and Insect Pest Control Cauliflower seedlings are prone to damping-off, and prevention should be the main method. When the disease occurs, it can be used to prevent and treat rickets and green hens on the 1st. At the same time, the diseased seedlings should be removed immediately, and a layer of dry fine soil or ash should be sprinkled on the soil surface. , Reduce soil moisture and control disease spread. Insect pests mainly include Pieris rapae, Plutella xylostella, aphids, etc., which can be used to prevent and control insecticides such as net worms, chlorpromazine, and imidacloprid, and no pests and diseases occur in the mid-to-late growth stages.
