Study on <i>Panax notoginseng</i> F.H.Chen Cultivation Under Forest

Abstract

To overcome the Panax notoginseng F.H.Chen facility cultivation high cost and the consecutive monoculture problems of cultivated land, to satisfy the market demand, to save the production cost, improve the utilization rate of forest land, increase the income of forest farmers, protect the ecological environment, we has been used Yunnan wenshan Panax notoginseng F.H.Chen high quality seedlings for carring out cultivation technology research under forests, according to plant spacing 25 cm ×30 cm to planting, used randomized block design, repeated three times. We choice the Nut forest and China fir forest that the altitude is above 1000m and forests canopy density pond are 0.8 in shuping township Hongjiang, Gracp forest and Kiwi fruit forest that the altitude is 900m and forest canopy density of 0.6 and 0.5 respectively in tangwan township. The test results in 4 forests showed that cultivation growth of nut forest cultivation of Panax notoginseng F.H.Chen, crown diameter, survival rate, three years raw tuber weight were higher than the other three kinds of forests land, China fir forest is better than that of grape and Kiwi fruit forest, grapes forest is higher than the kiwi fruit forest at crown diameter and survival rate, but high growth and tuber weight below the kiwi fruit forest. when we cultivated Panax notoginseng F.H.Chen for scale cultivation under forests, Research results show that we should preference chioce Nut forest in Nut forest, China fir forest, Gracp forest and Kiwi fruit forest at Panax notoginseng F.H. Chen cultivation. because the nut are broadleaf deciduous tree species, lots of fallen leaves decomposed by decaing, increased the soil humus content that makes more loose fertile soil, better permeability, and damp, cool, more diffuse light and scattered light under forests. It is comformed to Panax notoginseng F.H.Chen ecological habit and the rule of the growth and development, and the Panax notoginseng F.H.Chen liked cloudy, joied the cool shade under forests, avoid direct light, liked oblique or scattered light. The Panax notoginseng F.H.Chen large scale cultivations undergrowth can overcome the facility cultivation cost high, production input more, technology is difficulty disadvantages such as, it’s can save the production cost, improve the utilization efficiency of forest land and increase the income of forest farmers, drive to get rich of local forest farmers, protect the ecological environment, promote the sustainable development of Panax notoginseng F.H.Chen industry.
