Embodiment 1

[0020] A cutting method of ginkgo, comprising the following steps:

[0021] (1) Seed collection strips: between late May and mid-June, when the new shoots of Ginkgo biloba are semi-lignified, the seed strips are collected;

[0022] (2) Seed bar treatment: put the seed bar into clear water to moisturize, keep 2 leaves for each seed bar, limit the length of each seed bar to 2cm, and the distance between the upper cut and the buds of the seed bar is 0.6 cm, the base of the notch is in the shape of a flat cut, and the lower notch is in the shape of a horseshoe. Bundle the seed strips, 50 seed strips per bundle, soak the lower end of each bundle of seed strips in the GGR solution for 2 hours, and take them out for later use;

[0023] (3) cutting bed preparation: make cutting bed in sunny place, the length of cutting bed is 4m, width is 2m, and depth is 45cm, spread 30cm thick river sand on the bed surface of cutting bed, pour water thoroughly after levelling, use Spray the river s...

Abstract

The invention provides a cuttage method for gingkoes. The cuttage method includes the following steps: 1, collecting seed branches, wherein from the late May to the mid-June, the seed branches are collected when newly-grown branches of the gingkoes are half lignified; 2, processing the seed branches, wherein the seed branches are placed into fresh water for moisture preserving, two or three leaves of each seed branch are kept, the length of each seed branch is limited to range from 10 cm to 16 cm, the distance between upper sheared wounds and buds of the seed branches ranges from 0.6 cm to 1 cm, the seed branches are bound, the lower ends of the seed branches in each bundle are soaked into a rooting powder solution for two hours, and the seed branches are taken out for preparing; 3, preparing a cuttage bed, wherein the cuttage bed is made in a field exposed to the sun, river sand with the thickness 30 cm is laid on the bed surface of the cuttage bed, leveled and then thoroughly watered, the river sand is sprayed with disinfectant while the river sand is overturned, the cuttage bed is covered with a plastic film for nine days, the plastic film is removed at the time four days before the cuttage bed is used, and the river sand is overturned, ventilated, aired and then leveled; 4, carrying out cuttage. By means of the cuttage method, grafted seedlings are high in survival rate, the seedling growing cost is reduced, and the market requirement can be met.

Description

technical field [0001] The invention relates to a cutting method of ginkgo. Background technique [0002] Ginkgo biloba is a rare tree species left over from the Mesozoic Era. Ginkgo biloba is a large deciduous tree with a diameter at breast height of up to 4 meters. The bark of young trees is nearly smooth and light gray. short spurs. Born in natural forests at an altitude of 500-1000 meters, acidic (pH 5-5.5) yellow soil, and well-drained areas, it often grows vigorously with coniferous and broad-leaved tree species such as cedar, torreya, and blue fruit trees. [0003] Ginkgo is a positive tree, and it likes moderately moist and well-drained deep loam, and is suitable for growing in subtropical monsoon regions with superior water and heat conditions. It can grow well in acidic soil (pH4.5) and calcareous soil (pH8.0), but neutral or slightly acidic soil is the most suitable, and it is not tolerant of waterlogging, and it is more drought-tolerant, only in too dry places ...
