Method for improving land for cultivating ginkgo saplings

Abstract

The invention provides a method for improving land for cultivating ginkgo saplings and relates to the technical field of nursery stock propagation. The method comprises the following steps of plowing the land to be sowed, evenly scattering a soil improvement agent on the surface of soil which is plowed, wherein 85 kg of the soil improvement agent is scattered for each mu, and then smashing and flattening the soil with a rotary cultivator, wherein sowing can be conducted on the flattened land. The soil improvement agent is formed by mixing and compounding, by weight, 35 parts of carbonized base materials, 15 parts of nano-silica, 16 parts of wormwood, 65 parts of saw powder, 25 parts of bamboo leaves, 6 parts of lysimachia foenum-graecum, 5 parts of honeysuckle, 6 parts of schizonepeta, 4 parts of divaricate saposhnikovia roots, 7 parts of radix sophorae flavescentis, 6 parts of felwort, 3 parts of dandelion and 5 parts of folium isatidis. A preparation method of the soil improvement agent comprises the steps of mixing the raw materials in proportion, pulverizing the raw materials into 150 meshes, and obtaining the soil improvement agent. By means of the method, the germination rate of seeds can be raised, improved soil is loose and breathable, fertilizer conservation capability is great, the growing period can be prolonged, nursery stock roots and stems are high in growth speed, and it is helpful to increase economic benefits of ginkgo sapling cultivation.

Description

technical field [0001] The invention relates to the technical field of nursery stock breeding, in particular to a method for improving land for 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 s...

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
