Virus-free ginger cultivation
One week before sowing germination sowing, select sunny sun-turning seed blocks for several days, so that the ginger skin becomes dry and white, then put it in a straw basket with straw, head inwards, put the tails outwards and lay layers, cover the straw Or straw, tied with a rope, placed in a greenhouse or plastic greenhouse, keep the basket moist, the temperature is 20-30 °C. After 20 days, the young shoots were taken out at a length of 1 cm and cut into small pieces. Each piece had 1-2 shoots. The wounds were sowed after being disinfected with wood ash. Soil preparation fertilization chooses deep soil, rich humus fertilizer land cultivation, deep sun exposure, making it loose weathering, in order to facilitate root growth. Maturity per acre base cooked cattle, pig manure 2000-2500 kilograms or 3500-4000 kilograms of concentrated livestock manure, compound fertilizer 20 kilograms. The sowing of the live broadcast in the appropriate period is expected from late April to early May. The south and low-heat valley areas are sown in mid-March. After germination or cultivating with a plastic film can be sowed 15-30 days earlier to extend the growth period and increase yield. 150-200 kilograms of ginger per acre. Cultivation methods should be properly sowed in order to prevent the roots from being exposed during the growth and reduce the quality. The sorghum cultivation, after the formation of the land, a ditch is made, the width is 1.2 meters, the width of the ditch is 30 centimeters, and three planting ditches are evenly opened for each ditch. After applying the base fertilizer and the soil, plant the seedlings at a spacing of 20 cm, planting 6000 per mu. -8000 strains. This method can increase soil permeability, increase soil temperature, and prevent water rot and roots in flat lands with high groundwater levels (eg, rice fields). In the ridge cultivation, the land is turned upside down and flattened, and no rakes are made. The bottom of the planting ditch is laid at a spacing of 50 cm and mixed with the soil. The plants are planted at a spacing of 18-20 cm, and then the soil is used to make ridges. This method is suitable for terraces or slopes where the groundwater level is low and wind permeability is good. At the time of sowing, the germinating buds are placed upwards and the non-germinating seeds can be laid flat and obliquely. After sowing, cover 5-6 cm thick fine clay to make it emerge as soon as possible. Ginger can be planted in the sunshade, and the sowing date can be 1 month earlier than the open land, and the seedling emergence after the sowing is quick, the emergence of the seedling is good, and the growth period is long, which is conducive to high yield. The use of sunshade film to cover the protection in the later period, the harvest period can be extended by 15 days, but also conducive to increase production. Field management During the growth of ginger, cultivating soil 2-3 times, will be planted into ridge rows. According to the growing trend of the plants, combine cultivation with weeding and applying fertilizer 2-4 times. In the late growth period, the plants need more fertilizer and should be applied more frequently, and 0.5% compound fertilizer can be added to the human and animal waste water. The harvested ginger is harvested at the beginning of August, pickled kimchi or seasoned pepper sauce. From late October to November of old ginger, the yellow parts of the plant began to yellow, and the rhizomes were fully grown and matured. The ginger blocks harvested before the frost are heavy, resistant to storage and transportation, and can be seasoned or processed into dried ginger slices. Ginger is harvested in the middle or late June when the plants have 4-5 leaves. When harvesting, the rhizosphere soil of the plant was picked up, and the ginger was removed to cover the roots.
