Seedling growing planting method of maidenhair trees

Abstract

The invention discloses a seedling growing planting method of maidenhair trees, and belongs to the field of planting. The method particularly comprises the following steps of 1, seed collection; 2, seed soaking; 3, bud forcing treatment; 4, sowing and seedling growing; 5, finished healthy and strong seedling cultivation; 6, transplanting planting; 7, management after planting. All the steps are reasonable in matching, cultivated finished healthy and strong seedlings are good in physique and high in resistance, can still normally survive in seriously salinated soil and is good in nutrition absorption and conversion property, the utilization rate of fertilizer can be increased, the problems that in the prior art, the fertilizer applying amount is too large, and soil is hardened are gradually relieved, and planting improvement of the maidenhair trees returns to sound development. Flavonoid compounds in the finally cultivated maidenhair trees are large in content, and high economic value is achieved.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for growing seedlings of ginkgo trees. Background technique [0002] Ginkgo is a deciduous tree belonging to Ginkgoaceae, Ginkgo genus, gymnosperm, also known as ginkgo tree, Gongsun tree and so on. Ginkgo biloba appeared 270 million years ago. It is the oldest relict tree species left after the Quaternary glacial movement, known as the "living fossil". Ginkgo biloba has extremely high economic value, medicinal value and garden application value. For example, ginkgo leaves and seeds are rich in specific active ingredients such as flavonoids and terpenoid lactones, which have the effects of regulating immunity, preventing senile dementia and diabetes. The propagation methods of Ginkgo mainly include methods such as sowing propagation, tillering propagation, cutting propagation and grafting propagation. Among them, seed propagation is the most widely used, and field ...

Problems solved by technology

Because the seed coat of ginkgo seeds is thick, it usually needs to be treated before sowing to increase the germination rate. Currently, methods such as sand storage, water immersion, and hormone treatment are often used. Although they can achieve certain effects, they still cannot achieve the desired effect. level of expectations

In addition, most of the existing planting methods are to promote the growth of ginkgo trees by applying a large amount of fertilizers, but there is no improvement for the plants themselves. Long-term application of fertilizers will lead to a decline in soil fertility, and the problems of hardening and salinization are becoming more and more serious. However, the ginkgo tree itself has poor performance such as salt-alkali resistance, which will eventually seriously affect the development of the ginkgo tree and reduce its quality, which has caused a vicious circle.
