Embodiment Construction

[0021] This embodiment is carried out in Qilin District, Qujing City, Yunnan Province. The average altitude of the site is about 1900m, the slope is less than 30°, and the soil pH value is between 6.0-7.0. The soil is loose and rich in humus, mainly sandy loam. Soil temperature and moisture sensors, air temperature and humidity sensors, communication facilities and monitoring equipment, as well as corresponding irrigation equipment and humidification equipment are installed in suitable locations. Early-fruiting walnuts with a period of 3 years from seedling planting to flowering and fruiting, and Yunnan yew are selected. Seedlings are used as interplanted varieties.

[0022] First, from December to January of the next year, select walnut seedlings with a seedling height of 60-70cm, a diameter of 1.2-1.5cm, a main root length of 25-30cm, a root diameter of 2.5-3cm, no mechanical damage, and no pests and diseases. 40 plants are planted at a density of 3 × 5m. Before planting, wr...

Abstract

The invention relates to the technical field of tree planting, in particular to an interplanting technique of Taxus yunnanensis and walnuts. The invention aims at providing a stereoscopic ecological cultivation method of the Taxus yunnanensis and the walnuts. Through the reasonable interplanting of the Taxus yunnanensis and the walnuts, in combination with a precise field management technique, walnut trees create a more suitable growth environment for the Taxus yunnanensis and the goals of improving the survival rate and the growth speed of the Taxus yunnanensis are achieved; and by changing the branch shapes of the walnut threes at proper time and regulating the illuminating conditions, the growth of the Taxus yunnanensis is prompted at an early stage and the content of taxol in the Taxus yunnanensis is improved at a harvesting stage; and at the same time, the Taxus yunnanensis can take a reverse supplementing effect to the walnuts through the insect propelling characteristic of the Taxus yunnanensis, the influences caused by injurious insects to the walnuts are reduced and the quality of the walnuts is improved. The Taxus yunnanensis and the walnuts supplement each other and the produced economic benefits per unit land are greatly improved.

Description

technical field [0001] The invention relates to the technical field of tree planting, in particular to the interplanting planting technique of yew and walnut in Yunnan. Background technique [0002] Taxus yunnanensis is an endemic species with Yunnan as the center distribution area. It is mainly distributed in Baoshan City and Tengchong County in western Yunnan, Dali, Zhongdian, Lijiang and Weixi in northwestern Yunnan. It often grows in subtropical mountains at an altitude of 1800-3500 meters, and its habitat is scattered or in blocks in shady slopes, semi-shady Zhongshan, subalpine gentle slopes, valleys, dark coniferous forests on both sides of streams, Zhongshan coniferous and broad-leaved mixed forests, and evergreen broad-leaved forests. Growing like a tree, often becoming an understory tree. Taxus yunnanensis contains paclitaxel, harringtonine and other ingredients, which are effective drugs for treating various cancers; after chemical analysis, the paclitaxel conten...
