Detailed Explanation of the Latest Key Points for Field Management of Panax notoginseng
Panax notoginseng (sanqi) is a very good medicinal herb in China, mainly using its roots for medicine, with various effects such as promoting blood circulation and removing blood stasis, reducing swelling and relieving pain. Although it has a vast wild area, in order to meet market demand, the area of artificial cultivation is now growing larger and larger. When planting Panax notoginseng, field management is very important. So today, the editor brings you the field management techniques for Panax notoginseng cultivation. Let's take a look below!
1. Intertillage and weeding
Weeds have a very large impact on the growth of Panax notoginseng. When planting Panax notoginseng, the first thing we must do well is intertillage and weeding. When weeds are found in the field, they must be pulled out in time to prevent them from robbing Panax notoginseng of nutrients and water for growth. But note that because the roots of Panax notoginseng are distributed relatively shallowly, care must be taken during weeding to prevent damaging the roots. If the roots become exposed, soil should be added in time to ensure root growth. Then do a good job of intertillage to improve soil permeability, enhance the growth ability of Panax notoginseng, and ensure normal growth of Panax notoginseng.
2. Building shade sheds
Panax notoginseng is very sensitive to sunlight, so when planting we must pay attention to doing a good job of building shade sheds. The height of the shade shed should be controlled at about 1.5 m, and curtains or straw and other materials should be covered on top of the shed. In spring and autumn each year, the shading degree can be appropriately reduced, controlling the light transmittance at about 50%. Adjust the light transmittance reasonably as Panax notoginseng grows. For Panax notoginseng plants about 3-4 years old, during the flowering and fruiting period, control the light transmittance to increase the yield of Panax notoginseng, promote root expansion, and enhance the disease resistance of the plants.
3. Water and fertilizer management
During the germination period and flowering period of Panax notoginseng, if there is drought, then water in time to keep the soil moist and promote the growth of Panax notoginseng. However, during rainy seasons and other periods with abundant water, we must also ensure good drainage work, and after rain reduce the soil water content in time to prevent water accumulation from rotting the roots. When Panax notoginseng enters the peak growth period, pay attention to reasonably applying nitrogen fertilizer as a top dressing. According to the growth conditions of Panax notoginseng and the fertility of the soil, reasonably supplement the corresponding fertilizers to meet the nutritional needs of Panax notoginseng and promote its growth.
4. Pest and disease control
Pests and diseases are very harmful to Panax notoginseng. When planting Panax notoginseng, we must fully understand the various common pests and diseases of Panax notoginseng. For example, damping-off disease, root rot disease and various other diseases all cause various different harms to Panax notoginseng. So when planting, we must often observe the growth of Panax notoginseng. Understand the onset symptoms of various pests and diseases, so that when disease occurs we can quickly know the specific situation and then make corresponding control measures. Then there is the need to use medicine reasonably and not blindly, to avoid causing pesticide damage to Panax notoginseng.
The above is a brief introduction to the key points of field management for Panax notoginseng. The management work for Panax notoginseng is very important, so everyone must absolutely not neglect it. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
