Embodiment 1

[0060] In September 2010-December 2013, it was tested in Guilin Forestry Research Institute, Guangxi.

[0061] 1. Seed collection

[0062] Ginkgo seeds must have good maturity and a high embryonic rate, and the seed nucleus should be large rather than small. Generally, the maturity period of ginkgo in Guilin, Guangxi is from late August to mid-September. When the outer skin of ginkgo seeds turns from light yellow to orange-yellow and wrinkled, it is fully mature. Select the mature plants with an embryonic rate of more than 80% and the number of seeds in the range of 400-600 grains / kg as the mother tree for seed collection.

[0063] 2. Seed handling and storage

[0064]After the seeds are harvested, the outer and middle skins should be removed immediately, rinsed repeatedly, and then dried in the sun for 1 to 2 hours. After the seeds have no moisture on the surface, they should be taken back indoors, and the broken fruits and sundries should be removed, and then put into bamb...

Abstract

The invention relates to a ginkgo green seedling cultivating method. The method comprises the following steps of collecting seeds; processing and storing the seeds; accelerating germination; selecting and preparing nursery land; sowing; weeding and loosening soil; shading the sun; performing top application; performing subsoil application; resisting drought; transplanting; transplanting and fixing row spacing of plants; managing green seedlings and the like. Practice proves that massive ginkgo green seedlings and ginkgo saplings for greening are cultivated on a large scale by the method, and an example for cultivating the ginkgo green seedlings and ginkgo green trees for urban construction is made.

Description

technical field [0001] The invention relates to a method for cultivating green ginkgo seedlings, which belongs to the field of agriculture. Background technique [0002] Ginkgo biloba is commonly known as ginkgo tree, gongsun tree, duck palm tree, also known as "living fossil". It is a second-class protected plant in my country. Important tree species for major urban greening. Ginkgo green seedlings refer to the ginkgo seedlings planted on both sides of courtyards, roads and rivers; [0003] In the prior art, there are many problems in cultivating ginkgo green seedlings, and the disease is serious. After sowing in some places, the seedling rate of the whole nursery is less than 30%, and the seedlings are weak. After 2 to 3 years of cultivation, they cannot reach the standard for planting out of the nursery. Unable to meet the needs of afforestation; [0004] Cultivation refers to the process of using seeds or certain tissues of plants to grow whole plants of plants. Cont...
