    How to water ginger
    Ginger has different requirements for watering in different growing seasons. When sowing, you must water the bottom water, and usually do not start watering until the emergence of about 70%. After pouring this water, the soil should be kept moist frequently to prevent the soil surface from compacting and affecting the emergence. It is advisable to pour small water in the early stage of the seedling stage, and after the soil is wet and dry, carry out shallow scooping. In the late stage of seedlings, it is in the hot summer season, the weather is hot and dry, and the soil evaporation is large. The watering frequency should be appropriately increased, and the relative humidity of the soil should always be 65% to 70%.
    It is better to water in the morning or evening in summer, do not water at noon. In addition, after a rainstorm, water should be poured to cool down the horse in the form of horse race water, and the water should be drained in time to prevent the water in the ginger field from causing the ginger to rot. In the vigorous growing season, water is usually poured once every 4 to 6 days, and the relative humidity of the soil is often maintained at 75% to 85%. 3 to 4 days before harvest, and then watered again, so that ginger can bring moist soil during harvest. , Conducive to storage under the cellar.
    1. Water management during germination:
    In order to ensure the smooth emergence of ginger, the bottom water must be irrigated when sowing, usually the first water is not started until the emergence of about 70%. However, it should also be flexibly controlled according to the local soil quality and conditions. If it is sandy soil, the water retention is poor, and the weather is dry. Although the seedlings have not yet emerged, the soil is very dry. In this case, watering should be appropriate. After pouring this water, the soil should be kept moist frequently to prevent the soil surface from compacting and affecting the emergence. If it is clayey soil and has good water retention, it can be watered after about 70% emergence.
    After emergence, the first water should be poured in a timely manner, not too early or too late. If it is poured too early, the soil surface is easy to set, the buds are difficult to unearth, and it is easy to cause uneven emergence. If it is watered too late, the ginger buds become dry, and the bud tips tend to dry out.
    2. Water management at seedling stage:
    Plants in the seedling stage are small, grow slowly and require little water, but the water requirement in the seedling stage is relatively strict and water is indispensable. It is advisable to irrigate small water at the early stage of seedling stage. When the soil is not wet after the irrigating period, shallow watering and soil loosening will be helpful to increase ground temperature and promote root development. The late seedlings are in the hot summer season, the weather is hot and dry, and the soil evaporation should be increased. The watering frequency should be appropriately increased, and the relative humidity of the soil should be maintained between 65% and 70%, which can prevent soil drought and reduce ground temperature. It is better to water in the morning or evening in summer, do not water at noon. In addition, after a heavy rain, the water should be poured into the water to cool down and drained in a timely manner to prevent water accumulation in the ginger field and cause the ginger to rot.
    During the entire seedling period, pay attention to the uniform water supply, not to dry or wet. If the water supply is uneven, not only the ginger seedlings are short and their growth is inhibited, but the new leaves that occur are often distorted. Seedlings grow normally.
    3, vigorous growth period watering:
    After the beginning of autumn, a large number of branches and new leaves occurred in the upper part of the ground, and the rhizomes in the lower part of the ground quickly expanded. In this period, the plants grew fast, the growth was large, and water was needed. In order to meet the needs for vigorous growth, water is usually poured once every 4 to 6 days, and the relative humidity of the soil is often maintained at 75% to 85%, which is conducive to the rapid formation of product organs. 3 to 4 days before harvesting, and then water again, so that the ginger can be moistened with soil during harvest, which is conducive to storage in the lower cellar.
    The early temperature of ginger planting is low and the rainfall is heavy, which affects the growth of ginger seedling root system. In order to prevent water accumulation in the ginger field and waterlogging of ginger seedlings, the drainage and drainage work in the field should be done well, so that the trenches and ditches are connected, and the rain stops and the water is dry, which is conducive to the growth of ginger. In the later stages of seedling growth, the temperature rises, and the grass surface, rapeseed hulls, and pea stalks can be used to cover the water surface, which has a good effect on reducing soil evaporation and preventing drought and moth. When the ginger seedlings have 5 to 6 leaves, they are irrigated with water in the morning and at night to resist drought, so that the ditch maintains a depth of 2 to 3 cm. In summer and autumn, when the weather is clear and rainless, the method of irrigation in the evening and drainage in the morning, or the method of irrigation in the evening can be better.
