How should ginseng be managed in autumn, winter and spring? Please explain the methods.
Autumn, winter and spring are the overwintering dormancy period for ginseng, and field management during this stage is an important production step that cannot be ignored. The main tasks are cold protection and moisture conservation, and the key management points are: sealing the beds in autumn, allowing snow cover in winter, and digging drainage ditches in spring.
Applying cold-protection soil in autumn to seal the beds mainly means sealing the bed surface, bed sides and bed ends tightly. This not only keeps the bed soil loose, but also prevents damage from slow thawing and frost. For ginseng newly planted that year, in combination with clearing the drainage ditches, scoop the soil removed from the ditches and the soil from the work paths onto the ginseng beds, covering them with 15-20cm; the bed sides must be pressed firmly and the bed ends wrapped well. After clearing field weeds from previously planted land, water thoroughly, and after disinfecting the soil, evenly cover the bed surface with leaves or rice straw or corn stalks to 3-5cm, then seal with overwintering soil to 8-10cm. This not only prevents freezing and drought, but also prevents rain and snow in autumn, winter and spring from forming a hard crust on the original topsoil of the ginseng beds, and can also protect sun-facing slopes and wind-exposed ginseng land from damage caused by slow thawing and frost.
Snow is a treasure for ginseng, but improper use can also be harmful. Before the ground freezes in early winter, because temperatures are unstable, snow accumulation cannot persist, so snowmelt water must be prevented from harming ginseng. Especially for newly planted and autumn-sown land, snow on the bed surface should be pushed off promptly after snowfall. After the ground freezes, let snow accumulate naturally; if snowfall is light, add snow manually by scooping snow from the work paths and around the beds onto the bed surface, so that the snow on the bed surface reaches a thickness of about 15cm, achieving cold protection and moisture conservation.
In early spring, the accumulated snow begins to melt, and because temperatures are unstable, alternating freezing and thawing often occurs. To avoid snowmelt water harming ginseng, the snow on the bed surface should be pushed off promptly. Around Qingming, drainage ditches should be cleared and dug promptly to prevent peach blossom floodwater from pooling and damaging the beds or overflowing over the beds and soaking the ginseng. If ginseng is soaked by peach blossom floodwater, the buds and roots rot easily, and in severe cases the ginseng dies. After clearing debris from the bed surface and ditches, keep the ginseng land clean and the water flowing freely to reduce sclerotial diseases of ginseng.
