Six measures for high yield cultivation of ginger

1. Strictly select land and avoid continuous cropping. Ginger in high temperature and humidity environment, prone to rot disease, commonly known as ginger plague. Ginger blast is a bacterial soil-borne disease, which causes serious continuous cropping and a large number of yield reduction. Because ginger has this destructive disease, ginger should not be continuously cropped, but should be rotated with rice, cruciferous crops, leguminous crops, etc. for 3-4 years. Ginger planting to choose fertile soil, deep soil, organic matter more loam or sandy loam is good. The field is required to be slightly higher in terrain, convenient for irrigation and drainage, and not easy to accumulate water, which is more favorable for preventing the occurrence of ginger plague. Second, disinfection germination, promote early hair. Ginger planting should select fully mature ginger, hypertrophy, with 1-2 strong buds, no disease of old ginger as seed ginger. Ginger seeds need to be disinfected and germinated before sowing. Disinfection methods are many, with 1: 1.5: 120 Bordeaux solution soaking 20 minutes can kill the surface of ginger bacteria. After the ginger is disinfected, it is first dried for 2-3 days. When the moisture on the surface of the ginger blocks disappears, it can be stacked and covered with straw or hemp bags for heat preservation and germination. It is required to maintain humidity and temperature conditions of 20-25℃. When the ginger buds grow to 1 cm, they can be sown. Third, timely sowing, reasonable dense planting. The sowing period of ginger in South China is generally February to March. The size of the seed ginger is 70-100 grams. Ginger density to row spacing 40 cm, plant spacing 20-25 cm is good. Fourth, apply enough base fertilizer, scientific topdressing. Ginger is more resistant to fertilizer and has a long growth period. The principle of applying sufficient base fertilizer and multiple topdressing should be adopted. 1500- 2500kg pig dung and 10- 15kg potassium fertilizer are applied per mu as base fertilizer. Topdressing should be applied thinly, from light to thick. When the seedling height is 15 cm, thin fertilizer is applied once, and when the seedling height is 30 cm, the second fertilizer is applied. After every 20 days or so apply a topdressing. Nitrogen fertilizer was the main fertilizer in seedling stage, and potassium fertilizer should be applied more in rhizome expansion stage. Fifth, shade cooling, promote growth. Ginger is a shade resistant plant, not resistant to high temperature and strong light, scattered light is beneficial to growth. Therefore, shade should be carried out during summer growth to promote growth. Shading methods are many, can be intercropped with wax gourd, Pueraria lobata, taro and other crops, the use of these crops shade. Cool gauze can also be used to build a flat shed for shade. 6. Drought and waterlogging prevention, timely cultivation of soil. Ginger is not resistant to drought, nor to waterlogging, and has strict requirements for moisture. It is advisable to keep the soil moist during the growth period. During the summer high temperature period, should be timely watering cooling, early and late watering is good. Rainwater days should be removed in time to reduce the occurrence of ginger plague. The growth of ginger rhizomes needs a dark and humid environment. As the rhizomes grow upward, the rhizomes are easy to expose to the ground, the epidermis thickens and the quality deteriorates. Therefore, it is necessary to carry out soil cultivation. Generally, the soil is cultivated about three times. The depth of the soil can be determined according to the cultivation purpose. If the tender ginger is harvested, the soil should be deeper, so that the length of the ginger increases and the texture is crisp and tender. If the harvest ginger, then cultivate soil to shallow, so that the roots thick old health.
