Ginger management should be scientific

Hedgerow sunshade ginger likes temperature, but is not resistant to strong light and heat. Therefore, after planting, corn stalks with a height of 70 cm and 80 cm were inserted 12 cm to the south of the ginger ditch and woven into a flower hedge, which was slightly inclined to the north by 10 degrees to 12 degrees, so that the surface of the ginger ditch was shaded to facilitate the growth of ginger seedlings. The fertilizer absorption of ginger by stages is very strong, and topdressing should be done for 3 times in the whole growing period. When the ginger seedling is 3cm high, the compound fertilizer is 15kg / mu, which promotes the ginger seedling to grow vigorously; when the ginger seedling grows 3 branches, it is combined with pulling grass to carry on topdressing, soybean cake fertilizer 15kg / mu and ammonium sulfate 15kg / mu are applied to promote the rapid expansion of ginger; when the ginger seedling has 5cm 6 branches, the growth rate of ginger is accelerated, and more fertilizer is needed in this period, 25 kg ammonium sulfate is applied per mu. Fertilizer can be trenched 15 cm north of ginger seedlings. Timely watering ginger before emergence after sowing, the soil should be kept dry in order to increase the ground temperature and promote seedling emergence. After emergence to before harvest, the soil should not be too dry, so as not to affect the yield. Watering is usually carried out after the seedlings come out. The Beginning of Autumn to the Autumn Equinox, ginger is the fastest growing season, can be watered frequently, keep the ground moist, every fertilization, soil should be watered. The watering time should be carried out when the day is cool, the ground is cool and the water is cool, usually in the evening or early morning, and it is appropriate to pour deeply, thoroughly and without stagnant water in the dosage. In the rainy summer season, excessive stagnant water in ginger fields should be eliminated in time. In the middle tillage, the growth of ginger seedlings is slow, but in the high temperature and rainy season, weeds grow vigorously, which is easy to cause grass shortage, compete with ginger seedlings for fertilizer and water, and affect the normal growth of ginger. Therefore, weeding is very important, generally ploughing once or twice a month. Because the root distribution of ginger is shallow and the branching ability is weak, the middle ploughing should be shallow rather than deep. Cultivation should be combined with watering, fertilization and soil cultivation. Soil cultivation can reduce the ground temperature and is beneficial to the formation of ginger lumps. Generally, the soil is cultivated step by step, each time the soil is 3cm to 6cm thick, in order to prevent the ginger from being exposed and reduce the quality. Grass laying on the ground can also be used to reduce the ground temperature and keep the soil moist.
