Ginger, also known as yellow ginger, is cultivated in China as an annual vegetable. Ginger is a favorite seasoning and can be used medicinally. In recent years, consumption has continued to increase, and planting efficiency has been better. Ginger cultivation should mainly focus on the following items.
1. Fine soil preparation, adequate basal fertilization should be selected fertile soil, watering conditions are good, no ginger rickets plot, was slightly acidic fertile soil. On the basis of winter plowing, combine soil preparation with 3-4 cubic meters of quality chicken manure or 5,000 kilograms of high-quality circumfertility as base fertilizer. In the high-fertilizer plots, 60-65 centimeters of space is required for trenching, 100 kg of soybean cake, 50 kg of ternary compound fertilizer, 50 kg of potassium sulfate, 2 kg of zinc fertilizer, and 1 kg of boron fertilizer as seed fertilizer. . To prevent underground pests, use 2 kg of phoxim granules per acre and mix 12-15 kg of soil with a slush. Then level the floor.
2, choose a good seed, germination sowing. There are many types of ginger, and my county mainly grows dragon claw ginger, red bud ginger, and garden ginger. To select a high maturity, bright yellow color, no damage, lesions of ginger for the species. Select the sunny days will be ginger sun 2-3 days, until the surface of the soil shedding, and then piled, covered with straw or 2-3 days, then heat preservation germination. Germination can be used bed, temperature maintained at 20-25 °C. Before and after the rain, it can be planted when the shoot length is 1cm or the fibrous root grows 3-4cm. In order to prevent ginger disease, especially the occurrence of ginger borer. Before planting, the ginger is soaked with 20% of the plant ash for 30 minutes or soaked in Bordeaux mixture of 1:1.5:120 for 20 minutes. The planting density is 2035cm, and about 6000-10000 strains per acre are planted with a seed amount of 300-500kg. After planting, cover the compost or fine soil around 5cm and then cover the straw.
3, field management. 1 seedlings to do a good job of insulation, clearing ditch drain, check the seedlings fill and weeding work. The cultivator requires “early, diligent, shallow, and fine†to keep the net pine grass green. If the seedling stage grows slowly, use urea 2-3 kilograms per acre to add human urine or pig manure to the water. 2 late management. When the ginger seedling grows 5-6 leaves, "Ginger" is taken out. In mid-to-late June, bamboo poles or straws were used for shading. After the summer, the sheds were shed. After the end of May, the fertilizer was chased once every 10 days for 3-4 consecutive times, with 10 kg of urea per acre, 3 kg of potassium fertilizer dripping with water, or 80 kg of organic compound fertilizer per acre. After the summer heat, the soil was cultivated with cultivator every 10 days for 2 consecutive times. During the expansion of ginger rhizomes, deep cultivating was carried out. Ginger expansin was used to promote rhizome enlargement. When the drought was severe in July-August, horses were irrigated and Tanaka was not kept. Waterlogging. During the entire growth period of ginger, Yeba 2 was sprayed 600 times to 1,200 times, once every 10 days, three times in a row, and the prevention effect was particularly good.
4, pest control. Ginger diseases mainly include ginger borer and ginger leaf blight. July-August is the peak incidence of Jiangyan, which can cause large deaths within a few days. Prevention and control methods are mainly based on agricultural control, combined with chemical control. Before the onset of illness, use ginger to get 1 capsule or 50% mancozeb 30 g plus 1 dose of agrostatic streptomycin 2 g water 15 kg spray once every other week for 3 consecutive times. When the diseased plant was found, it was immediately removed and the disease was disinfected with lime. Insect pests of ginger mainly include cotyledon beetle, song-jojoba, ginger aphid, aphid, and the like, and can be controlled by 600-fold of 50% trichlorfon or 2000-2500-fold of the insect-killing insecticide or 2,500-fold spray of diterpenoid.
5, harvesting and storage. The harvest of ginger is divided into soft ginger and ginger according to the purpose. The ginger is usually harvested from the beginning of July to August. The ginger is harvested before and after the frost, and the ginger is not sold for the next year. May-June.
