Ginkgo leaf picking garden management method

Abstract

The invention discloses a ginkgo leaf picking garden management method. The method is characterized by comprising the following steps of planting, wherein ginkgo seedlings are planted according to thewide row spacing of 0.5 m and the narrow row spacing of 0.3 m after soil preparation, and the row spacing is 0.5 m; tip pruning, wherein all branches of 8-10 cm or above along the ground are cut by apruner after 1-2-year planting; branch fixing, wherein the upper parts of the old branches are pruned each year and the 3-4 young branches of the base parts of the old branches are remained after 2-year tip pruning; pruning, wherein the lateral branches with the narrow row spacing are pruned, and meanwhile the telome and the terminal buds are pruned; and sprout tiller cultivation, wherein the trunks are cut down along the ground after 12-15-year planting, the cross sections are covered with weeds or straws, sprout tillers are promoted, and 3-5 robust sprout tiller seedlings are remained. Thesprout tiller seedlings continue to be repeatedly operated according to the ginkgo leaf picking garden management method with the steps (1)-(5). According to the method, the planting density can be increased, the yield and quality of ginkgo leaves can be improved, the ginkgo planting and labor costs are reduced, the field planting benefits are improved, the income increase of farmers is facilitated, and the ecological environment can be protected.

Description

technical field [0001] The invention relates to the technical field of tree planting, and more specifically relates to a management method for a ginkgo leaf-picking nursery. Background technique [0002] Ginkgo biloba (Gingko biloba L.) is a rare and precious tree species unique to my country, commonly known as living fossils, pandas in the plant kingdom, and is a plant of the genus Ginkgo in the family Ginkgoceae. It accounts for about 70% of the world's total output. Ginkgo biloba mainly contains flavonoids and terpene lactones, which have the functions of dilating blood vessels, improving cerebral circulation, inhibiting platelet activating factor, anti-oxidation, anti-virus, anti-bacterial and anti-inflammatory, enhancing memory and cognitive ability, anti-aging and preventing heart and brain Vascular diseases and other pharmacological effects. [0003] The content of ginkgo flavonoids in ginkgo leaves decreases with the growth years, so most of the leaves used in produ...

AI Technical Summary

Problems solved by technology

In the production of ginkgo leaves, the masses only pick the leaves and do not take care of them. The disorder of harvesting year after year has caused the farmers' interests to be not guaranteed, the ecological environment is destroyed, the planting management technology is backward, the product quality is unstable, the planting scale has been lingering, and the market competitiveness is lacking. , scale and low degree of industrialization
