Seedling culture and planting method of maidenhair trees

Abstract

The invention discloses a seedling culture and planting method of maidenhair trees. The method comprises the steps of (1) selection and soil preparation of cultivated land, wherein the selected land has the flat terrain and the thick soil layer, and is out of the wind and exposed to the sun and quick lime water, and overrotten farmyard manure and soil conditioner are sprayed and applied to the soil; (2) ridging of the cultivated land; (3) seed selection and germination accelerating, wherein full seeds are selected, put into seed soaking agents to be soaked, and put into a germinating box to conduct germination accelerating; (4) sowing and seedling breeding, wherein the seeds processed by germination accelerating are bred on seedling beds, so that seedlings are bred; (5) transplanting and field planting, wherein the seedlings are put into planting holes, and field planting is completed; (6) field planting management, wherein weeds are removed in time, fertilizer and water are applied to the soil, and insect and disease management is conducted. According to the seedling culture and planting method of the maidenhair trees, bacteria of the seeds can be controlled, introduction of dangerous diseases is avoided, the survival rate of the seedlings is improved, so that the seedlings grow better, and the growth speed of the seedlings is improved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for growing seedlings of ginkgo trees. Background technique [0002] Ginkgo tree, also known as ginkgo tree, grows slowly and has a very long life span. Ginkgo tree has appreciation, economic and medicinal value. Ginkgo biloba is the oldest gymnosperm left over from the Quaternary glacier movement, and it is one of the most precious tree species in the world, so it is regarded as a "living fossil" in the plant kingdom. [0003] At present, 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 seeding is generally used. 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 ho...

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.
