Ginger High-yield Cultivation Six Measures
First, strictly choose the land and avoid continuous cropping. Ginger encounters a high temperature and humidity environment and is prone to rot disease. Jiangyan is a bacterial soil-borne disease that causes severe disease and results in significant reductions in yield. Since ginger has such a devastating disease, ginger should not be used as a continuous crop. It should be carried out for 3-4 years with rice, cruciferous crops, and leguminous crops. Ginger is a good choice for fertile soil, deep soil, and organic or sandy loam. It is required that the plots have a slightly higher topography, facilitate drainage and irrigation, and are less likely to accumulate water, which is beneficial to the prevention of the occurrence of ginger borer. Second, disinfection germination, promote premature hair. Ginger should be selected ginger fully mature, hypertrophy, with 1-2 strong buds, disease-free ginger for ginger. Gingers need to be disinfected and germinated before sowing. There are many ways to disinfect. Germinating the surface of the ginger can be killed by soaking seeds in Bordeaux mixture at 1:1.5:200 for 20 minutes. After the ginger is disinfected, it is dried in the sun for 2-3 days. When the surface moisture of the ginger blocks disappears, they can be stacked and covered with straw or burlap for heat preservation and germination. When the ginger bud grows to 1 cm, it can be sown. Third, timely sowing, reasonable dense planting. Ginger sowing in South China is generally 2-3 months. The size of ginger is preferably 70-100 grams. Ginger density is 40 cm in spacing and 20-25 cm in spacing. Fourth, apply base fertilizer, scientific fertilizer. Ginger is more resistant to fertilizers and has a long growing period. It should adopt the principle of applying base fertilizer and multiple fertilizers. Apply 1500-2500 kg of pig dung per acre and 10-15 kg of potassium fertilizer as base fertilizer. Topdressing should be applied thinly, from light to strong. When the seedling height is 15 centimeters, a thin fertilizer is applied, and the seedling height is 30 centimeters to catch the second fertilizer. After every 20 days or so, top dressing is applied. Nitrogen fertilizer is the main seedling stage, and more potassium fertilizer should be applied during rhizome expansion. Fifth, shading cool, promote growth. Ginger is a negative-tolerant plant that is not resistant to high temperatures and light, and scattered light is good for growth. Therefore, shading should be performed during summer growth to promote growth. There are many methods of shading, which can be used in intercropping with crops such as wax gourd, kucah, and taro to make use of the shading of these crops. Cool shades can also be used for shading. Sixth, drought prevention, timely earth training. Ginger is not tolerant of drought and is not resistant to moisture. It requires strict moisture. It is advisable to keep the soil moist during the growing season. During the high temperature in summer, it is necessary to water and cool in time, and it is better to water early and late. In the rainy days, the water in the fields should be eliminated in time to reduce the occurrence of ginger borer. The growth of ginger rhizomes requires a dark and moist environment. With the upward growth of rhizomes, the rhizomes are easily exposed to the ground, and the epidermis becomes thicker and the quality deteriorates. Therefore, earthing should be carried out. Generally about three times. The depth of soil can be determined according to the purpose of cultivation. If you take tender ginger, the soil should be deeper, so that the length of the ginger is increased and the texture is crisp. If you collect old ginger, then the soil should be shallow to make the rhizome thick and healthy.
