The Latest Winter Panax notoginseng Planting and Management Techniques, Methods and Tutorial Key Points
Panax notoginseng, also called Tianqi, is a bulk medicinal herb with very common functions. Nowadays many medicinal herbs can be planted in winter, so Panax notoginseng is no exception, and planting Panax notoginseng in winter basically involves no pest problems, so many herb growers also relax their field management of Panax notoginseng. In fact, winter field management of Panax notoginseng is very important. If it is not managed well, then both yield and quality will be very low, so winter planting management must be done well. So how should Panax notoginseng be managed in winter? Now let the editor briefly introduce it to everyone.
1. Cutting back and retaining plants
Many Panax notoginseng growers do not really understand cutting back and retaining plants. In fact, cutting back means that after entering winter, the stems and leaves of Panax notoginseng above the ground should be pruned clean, while retaining plants means scientifically deciding whether to keep or remove Panax notoginseng plants according to their growth and disease conditions. For cutting back, what we need to pay attention to is that it must be pruned clean before the Spring Festival, and the pruned stems and leaves must be taken out of the Panax notoginseng field and disposed of cleanly. Never leave them near the Panax notoginseng field, or burn them and then use them as fertilizer, as this will reduce the yield and quality of Panax notoginseng.
2. Repairing the greenhouse
Repairing the greenhouse is very necessary. As long as it is not a greenhouse just built in winter, it generally needs to be repaired. First, we need to observe whether the greenhouse has leaks, whether the stakes are damaged, and so on. Then, according to the specific conditions of the greenhouse, install new materials where the greenhouse leaks rain, leaks wind, or where the plastic has deteriorated, and then rebuild the broken or collapsed wooden stakes in the field. Ensure the safety, ventilation and warmth retention of the field greenhouse.
3. Orchard cleaning management
Winter orchard cleaning management is a very critical step. We need to clear weeds, withered grass, fallen leaves and pruned stems and leaves from the Panax notoginseng field and destroy them in a centralized way. Then, in order to prevent the spread of pests and diseases in the field, a comprehensive disinfection should be carried out after cleaning the field. Generally, disinfection is carried out about once every half a month, so that pests in the coming year will also be greatly reduced, thereby reducing the difficulty of field operations in the coming year and improving the yield and quality of Panax notoginseng. Disinfection is mainly done by spraying carbendazim, and every part must be sprayed thoroughly.
4. Heat preservation and moisture retention
The weather in winter is relatively cold. Although Panax notoginseng has a certain cold tolerance, heat preservation measures still need to be taken to prevent Panax notoginseng from being damaged by frost, which would affect the yield in the coming year. So at this time, repairing the greenhouse becomes very important. We
only need to close the doors and windows of the greenhouse properly and cover it with a layer of plastic film for heat preservation. In this way, the heat preservation effect is very good. In winter, the soil is relatively dry. Although we need less water in winter, that does not mean no water is needed, so we should water appropriately according to the degree of soil cracking, so as to ensure the seedling emergence rate of Panax notoginseng in the coming year.
5. Scientific topdressing
After cleaning the field and disinfecting it, we should promptly apply a bud-covering fertilizer once, so as to prevent buds and seedlings from frost damage or pest damage. Bud-covering fertilizer is mainly composed of burnt soil and farmyard manure. After fermentation and decomposition, it is evenly scattered in the field, and a layer of dry grass also needs to be covered on top, which can play a role in heat preservation and moisture retention. Finally, around the Spring Festival, we need to apply clear manure water once to enhance soil fertility, which can improve its drought resistance.
