Stereoscopic ecological cultivation method of Taxus yunnanensis and walnut

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...

Problems solved by technology

The disease resistance of walnut is strong, and the main cause of harm to its growth is various pests. Finding a reasonable method of pest control is the key factor for the yield of walnut and fruit quality assurance. my country's walnut cultivation area is large, ranking first in the world, but The yield of walnuts has been low and unstable, the quality is uneven, the economic benefits are not high, the existing walnut orchard planting methods and management levels are low, and the pest control methods are unreasonable, which are important reasons for the inability to achieve high efficiency and high yield.
