Embodiment 1

[0025] Utilizing the mountainous area, using point hole planting, the eucalyptus is planted according to the row spacing of 350cm×350cm, and the yew is planted according to the row spacing of 80cm×80cm. The height of the eucalyptus seedlings used is greater than 100cm, and the height of the yew seedlings is greater than 50cm. After observation, 2 years after planting, the daily average shading intensity provided by eucalyptus to yew was 46% in the early and late growth stages, and in the vigorous growth period, the daily average shading intensity provided by eucalyptus to yew was 68%; The relative air humidity is 20% higher than that outside the forest, and the soil moisture content is 8.0% higher than that in the non-stereoscopic planting area. The number of branches of yew is increased by 65%, the yield of eucalyptus is equal to that of pure eucalyptus forest, the yield of yew is 80% of that of pure planting area, the content of paclitaxel is 90% higher than that of pure plan...

Abstract

The invention discloses a method for three-dimensionally ecologically cultivating eucalypts and taxus chinensis var. mairei. An ecological three-dimensional composite medicinal material community is established according to the bioecological characteristics of high growth velocity, need in sunlight and deep root system of the eucalypts, the bioecological characteristics of low growth velocity, shade tolerance and shallow root system of the taxus chinensis var. mairei and the characteristic that the eucalypts provide a shading environment for the taxus chinensis var. mairei, and the taxol content of the taxus chinensis var. mairei is increased. The method greatly increases the yield per unit and the utilization rate of land because aboveground and underground nutrient spaces can be fully utilized, maintains the ecological sustainability, maximally develops social benefits and provides a novel mode for the construction of commercial forests in China.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and relates to a three-dimensional ecological cultivation method of eucalyptus and yew. Background technique [0002] Eucalyptus is a plant of the Myrtaceae (Myrtaceae) genus Eucalyptus. It is naturally distributed in the Australian mainland and the islands east of the Wallace line. Because of its strong resistance to stress, drought resistance, wide adaptability, fast growth and high yield, etc., It has become one of the world's three major afforestation tree species. As an exotic fast-growing species, eucalyptus has developed rapidly in tropical and subtropical regions, especially in southern my country in recent years. Our country's forest coverage rate is low, but the demand for wood is relatively large. In the future, fast-growing forests represented by eucalyptus will still be developed as greening or timber forests. However, there are large gaps between eucalyptus forest...
