Iceberg is a new type of vegetable imported from South Africa. It is a succulent plant of the family Apricotaceae. It has thick leaves and crystal grains on the surface. The taste is crisp and tender, and the entrance is a healthy vegetable with high nutritional value. Its simple cultivation, strong cold resistance, drought and salt tolerance, is very suitable for planting in saline and alkali-producing greenhouses; more collaterals, high yield, about six months of growth cycle, suitable fertilizer and water can have a good harvest, and has not yet found Serious pests and diseases are good green foods. In the spring of 2015, the Jingrui Modern Agricultural Industrial Park in Tongzhou District of Nantong City introduced the planting of 8 acres of sheds with ice, the expansion of the crop in the autumn was 10 mus, and the yield per season was 2000-2,500 kilos, all sold to major supermarkets in Nantong and Shanghai. restaurant. The wholesale price per kilogram is 16-20 yuan, the retail price in the market is 30-36 yuan, the output value in two quarters can reach 80,000 yuan, and the cost per mu is only about 12,000 yuan. It is a good variety for farmers to plant, and the agricultural park can be marketed. Sales and order production. The cultivation points are now described as follows: Planting ice-cold vegetables to grow in greenhouses is mainly to prevent heavy rain, prevent light, and prevent cold in winter. Spring sowing at the end of February and early March, autumn sowing at the end of August and early September, sowing with seedling trays, filling the tray with the substrate, spraying 2 to 3 seeds per hole after sprinkled with water (take ear spoon), cover thin soil layer . The temperature after sowing should be about 20°C. When the spring sowing temperature is low, use the insulation shed to cover the plastic film. 20 to 40 days after sowing, the seedlings can be transplanted when they have 4 to 5 leaves. Field Management Before transplanting, Daejeon applied 2,000 kg of organic manure per acre. The row spacing of transplanting plants is 30 cm and 6000 plants can be planted per acre. Appropriate growth temperature of iceberg is 20-30 °C, and it grows faster in early summer, and in the high-temperature season in July-August, the shade net is covered in autumn. Icebergs are more resistant to drought, but they are also too dry. Weeding once a month, applying a nitrogen fertilizer within 10 days after transplanting, applying 15 kg of urea per acre, can be sprinkled on the line after the sprinkler, after each harvest 3 days after application of urea 15 ~ 20 kg. Harvesting method Ice planting can be harvested after about 12 months in the main stem, about 2 to 15 centimeters. When the temperature is low in the early morning, the main stem and lateral branches are cut off from the roots by 5 to 6 centimeters, and a box of 500 grams is put into the market for sale. Long-distance transport should be pre-cooled and transported in a low-temperature storage tank. The iceberg can be harvested in batches and harvested in about 30 days. About 500 kilograms can be harvested per acre. About 4 batches are harvested each season. Spring sowing is harvested at the beginning of July and autumn sowing is completed at the end of February of the following year. Two-year greenhouse cultivation in the whole year can harvest 4,000 to 5,000 kilograms. Puyang Linshi Medical Supplies Co., Ltd. , https://www.linshihealths.com
