InactiveCN106508382APlanting stable yieldGratifyingPlant cultivationCultivating equipmentsSugarRhizome
The invention provides a rhizoma polygonati planting method and application of same in plantation of polygonatum multiflorum. The method comprises the steps of selecting land and preparing soil, conducting treatment of the roots of rhizoma polygonati, planting, conducting water and fertilizer management in the later period, weeding and conducting pests management, and harvesting. The method changes the technical status quo of extensive plantation of rhizoma polygonati in the prior art, and provides a scientific, integrated and systematic technical scheme to the soil, base fertilizer, plant and root treatment in the planting process, the field management after the planting and other crucial factors. According to the polygonatum multiflorum planted by applying the method, the Rhizoma polygonati seedling can grow to the height of 120cm, the Rhizoma polygonati yield per mu increases by more than 4 times, and even as high as 10 times. As being tested, the Rhizoma polygonati planted by applying the method has a good drug property and a good anti-disease capability, a sugar content attaining more than 10 and even reaching as high as 12 with a good quality which far surpasses the sugar content standard of Rhizoma polygonati stipulated in Dictionary of Chinese Medicine. The method is suitable for large scale promotion and plantation, thus achieving the stable yield and high yield effect of Rhizoma polygonati plantation.
