Rhizoma polygonati planting method and application of same in plantation of polygonatum multiflorum

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, more specifically, to a method for planting Polygonatum polyflora and its application in planting Polygonatum multiflora. Background technique [0002] Polygonatum is a plant of the genus Polygonatum, with transverse rhizomes, cylindrical, and enlarged nodules. Leaves whorl, sessile. Medicinal plants. Among them, Polygonatum multiflora is distributed in Anhui, Henan, Guizhou, Hubei, Guangdong, Hunan and other places in China. It grows in areas with an altitude of 500-2100 meters. It is generally born in shrubs, under forests and in the shade of hillsides. It is a perennial herb. , rhizome hypertrophy, usually beaded or nodular, rarely nearly cylindrical, 1-4 cm in diameter, 50-200 cm high, usually with 5-30 leaves. The flowering period is from May to June, and the fruiting period is from August to October. [0003] Rhizoma Polygonatum is used for both medicine and food. It is a prec...

Problems solved by technology

[0006] Rhizome propagation and planting is a common planting method, but the existing rhizome propagation and planting technology is relatively extensive, and there is a lack of scientific technical solutions for key factors such as soil, basal fertilizer, treatment of plant rhizomes, and field management after planting.

The existing extensive planting technology is an important factor affecting the property of Polygonatum, low yield, low disease resistance, and unstable overall planting effect
