Cultivation method of ginkgo trees

Abstract

The invention provides a cultivation method of ginkgo trees, belongs to the field of agriculture, particularly relates to the cultivation method of the ginkgo trees and provides a scientific and reasonable planting method of the ginkgo trees. The cultivation method of the ginkgo trees comprises steps as follows: (1), selection of land for seedling raising: a flat and leeward place which has deep soil layers, loose and fertile soil and good water drainage property, is exposed to the sun and can be conveniently watered and well-drained is selected for seedling raising; (2), germination acceleration and sowing: sowing can be performed immediately after sowing in autumn, and germination acceleration is unnecessary; (3), seedling management: seedlings have a short growth period and stop growing soon, root systems are not strong, and fertilizer application and dressing can promote growth of the seedlings remarkably; (4), cutting of the seedlings: the land with loose soil and good water drainage property is selected, and base fertilizers are sufficiently applied; (5), scion treatment: branches growing for 1-3 years are selected from a superior ginkgo tree growing strongly and cut into cuttings with the length of 10-15 cm, and the lower ends of the cuttings are treated with rooting powder and soaked for 10 seconds.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a cultivation method of ginkgo trees. Background technique [0002] Ginkgo is a deciduous tree of Ginkgoaceae and Ginkgo, also known as ginkgo, gongsun tree, duck foot tree, and cattail leaf fan. Ginkgo biloba is the oldest relict plant among the extant seed plants. All other plants of the same class as it are extinct, known as living fossils. Ginkgo biloba was born hundreds of millions of years ago, and the surviving ginkgo trees are rare and scattered. Old trees over a hundred years old are rare. Variations and varieties include: yellow leaf ginkgo, tower ginkgo, split ginkgo, weeping ginkgo, variegated ginkgo, etc. 26 species. [0003] Ginkgo tree, also known as ginkgo tree, grows slowly and has a very long life span. Under natural conditions, it takes more than 20 years from planting to bearing ginkgo fruit, and it takes 40 years to bear fruit in large quantities. Th...
