Problems solved by technology

Due to the high medicinal value of Evodia rutaecarpa, driven by profit, its wild resources are very few. Most of the existing Evodia rutaecarpa is cultivated. Low quality, poor quality, low content of active ingredients, no economic benefits, Evodia rutaecarpa resources are becoming increasingly depleted

Embodiment 1

[0016] The small trees of Evodia rutaecarpa with a row spacing of 3×4 meters and 1.5 years after planting are topped near the ground to promote branching, control their dwarfing, and make the first-level branches gradually become main branches; Topping forms secondary branches, and finally topping forms tertiary branches; pruning secondary and tertiary branches, cutting off dense branches, overlapping branches, downward branches, diseased and insect branches, etc.; through continuous pruning and management , It takes 3.5 years to make the whole plant form a tree type with short trunk and low crown, outer circle and inner hollow, wide crown, ventilation and light transmission, tree height of 1.43 meters, and crown coverage of 12.1 square meters.

Embodiment 2

[0018] The small trees of Evodia rutaecarpa with a row spacing of 3×4 meters and 1.3 years after planting are topped near the ground to promote branching, control their dwarfing, and make the first-level branches gradually become main branches; Topping forms secondary branches, and finally topping forms tertiary branches; pruning secondary and tertiary branches, cutting off dense branches, overlapping branches, downward branches, diseased and insect branches, etc.; through continuous pruning and management , It takes 3.6 years to make the whole plant form a tree type with short trunk and low crown, outer circle and inner hollow, wide crown, ventilation and light transmission, tree height of 1.39 meters, and crown coverage of 11.3 square meters.

Embodiment 3

[0020] The small trees of Evodia rutaecarpa with a row spacing of 3×4 meters and 1.9 years after planting are topped near the ground to promote branching, control their dwarfing, and make the first-level branches gradually become main branches; Topping forms secondary branches, and finally topping forms tertiary branches; pruning secondary and tertiary branches, cutting off dense branches, overlapping branches, downward branches, diseased and insect branches, etc.; through continuous pruning and management , It takes 3.9 years to make the whole plant form a tree type with short trunk and low crown, outer circle and inner hollow, wide crown, ventilation and light transmission, tree height of 1.49 meters, and crown coverage of 13.1 square meters.

Abstract

The invention discloses a three-grade branch pruning technology of fructus evodiae. The three-grade branch pruning technology comprises the following steps: carrying out tip pruning on branches near the ground of fructus evodiae young trees with the plant spacing of 3*4m and planted for 1-2 years; controlling the branches to be dwarfed so that primary braches are gradually divided into stem branches; carrying out tip pruning on the stem branches after autumn or spring to form secondary branches; finally, carrying out tip pruning to form tertiary branches; pruning the secondary branches and the tertiary branches; pruning dense branches, overlapped branches, downward branches, insect branches and the like; and continuously pruning and managing and enabling whole plants to form tree shapes which have short stems and low crowns, circular outsides and hollow insides and wide tree crowns, are ventilated and transparent, and have the tree heights controlled to be lower than 1.5m and the tree crown coverage of being more than 10 square meters within 3-4 years. According to the three-grade branch pruning technology, the fructus evodiae can be subjected to three grades of branch pruning so that the quality and yield of cultivation of the fructus evodiae are effectively improved and the labor cost is reduced; the germplasm resources of the fructus evodiae are effectively protected; the three-grade branch pruning technology has remarkable social and economic benefits and has a wide application prospect.

Description

technical field [0001] The invention relates to a new agronomic technique of Evodia rutaecarpa, in particular to a three-stage branch pruning technique of Evodia rutaecarpa. Background technique [0002] Evodia (scientific name Tetradium ruticarpum , formerly known as Euodia ruticarpa ), aliases Wuyu, tea pepper, lacquer pepper, smelly pepper tree, Zuolichunyouzi, rice pepper, etc., small trees or shrubs, 3-5 meters high, dark purple-red twigs, gray-yellow with the buds Or red rust-colored fluff, or sparse short hair. Evodia rutaecarpa mainly grows in sparse forests or shrubs in mountainous areas from flat to 1500 meters above sea level, and is more common in sunny slopes. After soaking and drying its fruit, it becomes the traditional Chinese medicine Evodia rutaecarpa, referred to as Evodia rutaecarpa. It is a bitter stomachic agent and analgesic. It is also used as an anthelmintic. [0003] Evodia rutaecarpa is recorded in the 2010 edition of "Chinese Pharmacopoeia". ...
