After the beginning of autumn, the weather was cool and entered the period of rapid enlargement of ginger tubers. During this period, ginger has a large demand for water and fertilizer, and more diseases and insect pests occur. This is also a critical period for prevention and control. The following five aspects should be focused on production: Watering should be diligent, ginger, wet, and not drought tolerant, and it is generally advisable to use shallow hoe soil after watering. In case of drought, the number of waterings should be increased, but flooding should not be allowed. September is the best period for the growth of ginger rhizomes, and the demand for water is obviously higher. Watering should be suitable once every 7 to 10 days. Water should be less when there is more rain. The top-dressing ginger grows for a long period and requires a large amount of fertilizer. In particular, the amount of fertilizer needed in the middle and late stages of ginger accounts for about 80% of the entire growing period. In mid-September, when ginger seedlings have 6 to 8 tillers, this is the rapid expansion of rhizomes, which can be top-dressed according to the growth of the plants, called “supplemental fertilizerâ€. The top dressing on the one hand promoted the lush stems and leaves, so that the ginger rhizomes quickly expanded; on the other hand, it prevented the defertilization of the late growth period and led to the premature failure of the stems and leaves, which affected the yield. Generally, 20 kg of nitrogen and potassium fertilizers are applied in the Mu, combined with topdressing, and boron fertilizer, zinc fertilizer and other trace fertilizers are added in a timely manner. Generally, 2 kg of zinc sulfate and 1 kg of borax are applied per acre, which has a very important effect on improving ginger yield and quality. For plots with de-fertilization, spraying potassium dihydrogen phosphate twice on the surface of the plot can significantly increase the yield at the later stage. Soil cultivation requires dark environmental conditions due to the growth of ginger rhizomes. Therefore, soil should be cultivated many times. Normal soil 2 to 3 times, the first time the soil in the top dressing, soil cover farmyard fertilizer is appropriate, not too thick, so as not to affect the emergence of the growth. After 15 days, the second and third soils were used. Finally, the soil was earthworms and the rhizome could not be exposed on the ground. Disease prevention and control of scorpion gangrene is a devastating disease in the production of ginger, and it is also a major factor that affects the yield of ginger. It should be based on comprehensive prevention and control measures. Can be used to change the rotation; digging drainage ditch, drainage flood control; or chemical control, can be used Jiangbao, ginger glutinous powder, green tyrants and other 1500 ~ 2000 times liquid irrigation. When a serious diseased plant is found, it must be removed in a timely manner, and lime should be used as a standard. After the ginger is harvested, the soil is buried deeply. The main pests are Ginger Aphids, Spodoptera exigua, Ginger, etc. It is important to regularly investigate the pest situation and do a good job of chemical control before pests occur. The use of pyrethroid pesticides, imidacloprid and other agents mixed spray control, spray control once every 7 to 10 days. Harvested in time in the middle of Hebei Province, the best harvest of ginger should be between October 20 to 25, Hebei Province, the southern region can be delayed properly for 3 to 5 days, the eastern production area can be harvested one week earlier. At this point, the harvest will not only freeze the ginger, but also make full use of the golden period of late-growth ginger production. Therefore, we must master the best timing for harvesting and must not be harvested prematurely. In order to facilitate the storage and return of nutrients, about 3 cm of stalks can be left to promote nutrient backflow, which is flexible according to market conditions.
