Rapid seedling method for maidenhair trees

Abstract

The invention provides a rapid seedling method for maidenhair trees, and relates to the technical field of nursery stock breeding. The method includes the following steps of: (1) soil improvement: turning over a land to be sown, and evenly applying a soil improvement agent to the surface of soil after turning over, wherein the amount of the soil improvement agent is 85 Kg per mu, a rotary cultivator can be used to smash and level the soil, and the leveled land can be used to sow; (2) seed germination accelerating: selecting seeds during early and middle of February, and putting the selected seeds into an insulating germination accelerating box to accelerate germination, wherein the seeds can be used to sow when the length of the radicle is identical to that of a seed stone; (3) sowing: completing sowing before spring equinox and sowing 2.5 ten thousand stains of seedlings per mu; and (4) management after sowing: keeping a seedbed wet before seedlings come up out from the ground, and managing the seedlings by adoption of the conventional method after seedling hardening. According to the rapid seedling method for the maidenhair trees, the sprouting rate of the seeds can be improved, the improved soil is loose and breathable, and the fertilizer maintenance ability is high; the growing period is prolonged, the growing speeds of roots and stems of the seedlings are fast, and the rapid seedling method for the maidenhair trees can improve the economic benefits of maidenhair seedling.

Description

technical field [0001] The invention relates to the technical field of nursery stock breeding, in particular to a method for rapidly growing ginkgo seedlings. Background technique [0002] Ginkgo biloba is a unique and precious tree species in my country, which is used for seed, leaf and wood. Ginkgo seed kernels are rich in nutrition and can be used both as medicine and food. Since ancient times, they have been the first-class dried fruit for health preservation and longevity, ranking fourth in the production of dried fruits in my country. Ginkgo wood is excellent, known as "silver wood", it is an ideal wood for making handicrafts, moulds, musical instruments and furniture, and its price is relatively high. The ginkgo timber forest 25 years after afforestation can reach 10 cubic meters per mu. Ginkgo is a light-loving tree species with strong drought resistance, but it is not tolerant to waterlogging and wind. Therefore, when choosing a cultivation site, you should choos...

Problems solved by technology

Conventional invisible seedling raising methods are common methods of sowing and seedling raising. After the ginkgo seeds are stored, they can be sown after completing the post-ripening stage before sowing. They can be sown without germination. This sowing method is relatively simple and easy to master. However, the emergence is late and irregular, the growth period of seedlings is short, and the yield and quality are slightly poor
