Ginger management in the late middle management four points

Watering ginger is hi wet and not drought tolerant, and it is usually suitable to water after shallow earthworms. 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 is suitable for 1 to 7 days, and little water is poured when there is a lot of rain. Watering time should be appropriate in the morning and evening. Try not to water at noon.

The top dressing ginger has a long growing period and requires a large amount of fertilizer, and in particular, the amount of fertilizer needed in the middle and late stages of ginger growth accounts for about 80% of the entire growing period. After the beginning of autumn, combining the removal of weeds or the demolition of ginger sheds for top dressing requires adequate fertilizer, complete nutrition, and lasting fertilizer effect. In the north side of the ginger seedlings, 15 to 20 cm from the base of the plant, a fertilization ditch is opened, with a depth of 10 cm. The Mushi roasted bean cake is 70-80 kilograms or the mature manure is 500 kilograms, plus nitrogen, phosphorus and potassium ternary compound fertilizer. 30 kilograms, spread the fertilizer evenly in the fertilization ditch after the cover soil, then drenched. In mid-September, when ginger seedlings have 6 to 8 tillers, it is a period of rapid root enlargement. According to the growth of the plants, the fertilizer may be topdressed as appropriate and called "supplemented fertilizer." 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. Mushi nitrogen fertilizer 4 to 5 kg. Combined with topdressing, timely supplement of boron fertilizer, zinc fertilizer and other micro-fertilizers, generally two grams of zinc sulfate topdressing, borax 1 kg, has an important role in improving the yield and quality of ginger.

Prevention and treatment of worm lice is a devastating disease in ginger production, and it is also a major factor that affects the yield of ginger. Should be based on comprehensive prevention and control measures, can be used for crop rotation; digging drainage ditch, drainage flood control; found diseased plants in a timely manner, and use lime to do the standard, after the ginger harvest, the soil buried here. The main pests are Ginger Aphids, Beet Armyworm, Ginger, etc. It is necessary to regularly observe the pests in a timely manner, and do a good job of prevention and control of chemicals before the outbreak occurs. Can be used imidacloprid or avermectin spray control, every 7 to 10 days control 1 times.

Harvested in a timely manner In the central region of Hebei Province, the best harvest period for growing ginger in open field should be from October 20 to 25, in the east of Tangshan, Qinhuangdao, etc., it can be properly harvested one week earlier. At this time, harvesting ginger will not freeze ginger, It can 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. For the sake of storage and nutrient return, we can leave about 3 cm of stalks to promote nutrient reflow.
