Six key points of high-yield cultivation of ginger: YEATION land avoids continuous cropping of ginger in high temperature and high humidity environment, which is easy to rot, commonly known as ginger plague, which is a bacterial disease, and continuous cropping is serious, resulting in a large number of production reductions. Because of this devastating disease, ginger is not suitable for continuous cropping, and it should be rotated with cruciferous crops and leguminous crops for 3~4 years. It is best to choose fertile soil or sandy soil with deep soil layer and rich organic matter for planting ginger. It is required that the irrigation and drainage of the field is convenient and it is not easy to accumulate water. Sow in time and plant in reasonable density. The planting density of ginger is 40 cm in row spacing and 20~25 cm in plant spacing. Scientific application of sufficient base fertilizer and topdressing. (1) Determine the fertilization method and dosage according to the measured formula: Before ploughing, carry out experiments according to scientific methods, convert the detected PH value, organic matter, N, P and K contents into C/N ratio, and formulate the fertilization formula according to the characteristics of ginger fertilizer demand. Ginger has strong tolerance to fertilizer and long growth period, so the principle of sufficient base fertilizer and repeated topdressing should be adopted. Apply pig manure 1500~2500 kg per mu, and potassium fertilizer 10~ 15 kg as base fertilizer. (2) Top dressing Qin Ying is very thin, from shallow to thick. Apply thin fertilizer once when the seedling height is 15cm, and apply secondary fertilizer when the seedling height is 30cm. After that, topdressing should be done every 20 days or so. Combined with spraying plant electronic fertilizer, the fertilizer efficiency can be supernormal. Based on the principle of high-energy electrons produced by plant photosynthesis and polarity induction of plant electrons, the level of cell division, molecular synthesis and nutrient matching digestion is improved, the metabolic frequency is accelerated, the plant nutrient dredging system is activated, and the super-fertilizer effect is produced. Nitrogen fertilizer is the main fertilizer at seedling stage, and potassium fertilizer should be applied more at rhizome expansion stage. When planting, cover or tie a small arch shed with plastic film to ensure the temperature needed for growth. Shading, cooling and promoting growth Ginger is a shade-tolerant plant, and scattered light is beneficial to growth. The shadow began in late May, with 7 points and 7 points for Yang. In late September, the network was removed and the map was divided, and then every 15 days. Prevent drought and waterlogging, and cultivate ginger in time. Ginger is neither drought tolerant nor waterlogging tolerant. It is wise to keep the soil moist during the growing period. During the high temperature in summer, it is best to water in time to cool down, especially in the morning and evening. In rainy days, the accumulated water in the field should be removed in time to reduce the occurrence of ginger blast. The growth of ginger roots needs a dark and humid environment. As the roots grow upward, they are often exposed to the ground, with thick skin and poor quality. Therefore, it is usually cultivated for about three times. The depth of culture can be determined according to the purpose of culture. If you harvest tender ginger, you should dig deep and increase the length of ginger to make it crisp and tender. If you harvest old ginger, you should plough it shallowly to make the roots strong.
