Embodiment 1

[0050] A method for cultivating high-quality and high-yield ginkgo biloba for ground leaves in low mountains and hills, the steps are as follows:

[0051] 1. Base Preparation

[0052] Choose a valley alluvial land below 410m above sea level, with a slope of 3°, purple soil, pH 6.5, good drainage, and far away from pollution sources as the garden site; at the beginning of winter, after clearing the weeds and shrubs at the base, carry out site preparation and open drainage ditches; combined with site preparation , 500kg of compound fertilizer mixed with NPK fertilizer per hectare according to the mass ratio of 1:1:1 is used as base fertilizer. 1000 times liquid to control pathogenic microorganisms in soil;

[0053] 2. Seed Nucleus Preparation

[0054] The quality of seed kernels should meet the standard of grade I and above stipulated in GB / T 20397-2006, the variety is "Kaijianghuang No. 1", the purity is 99%, the weight of 100 kernels of seed kernels is 261g, the clarity is 9...

Embodiment 2

[0071] A method for cultivating high-quality and high-yield ginkgo biloba for ground leaves in low mountains and hills, the steps are as follows:

[0072] 1. Base Preparation

[0073] Choose a low hillside land with an altitude of 619m, a slope of 21°, sandy soil or sandy brown soil, pH 5.9, good drainage, and far away from pollution sources as the garden site; at the beginning of winter, after clearing the weeds, shrubs and grasses at the base, carry out site preparation; combined with site preparation, Apply 800kg of compound fertilizer mixed with nitrogen, phosphorus and potassium fertilizers in a mass ratio of 1:1:1 as base fertilizer.

Abstract

The invention discloses a high-quality and high-yield cultivation method for leaf gingko in low-mountain hilly land. The method comprises the following steps of (1) preparing a base; (2) seedling/kernel preparation; (3) cultivation management; (4) crown shape regulation and control; and (5) leaf harvesting. According to actual conditions of site conditions of different afforestation lands, directseeding orchard building is carried out by using seed nuclei in gentle land, 2-3-year-old seedling transplanting orchard building is carried out on a sloping field, and the mode development of a newly-built orchard is promoted year by year from the gentle land to the sloping field; crown shape regulation and control treatment is carried out in time, and at key time nodes of growth of the leaf gingko, a compounded growth regulator and a quick-acting fertilizer are used as auxiliary materials to regulate and control excessive growth of branches, so that the number and quality of leaves are improved, and the purposes of luxuriant leaves, increase of the leaf yield per unit area and increase of the content of effective medicinal components are achieved; and by popularizing and applying the technology in low hilly areas, the purposes of saving the labor amount and the economic cost and effectively improving the fresh leaf yield per unit area and the effective medicinal component content ofthe leaf gingko are achieved.

Description

technical field [0001] The invention relates to the technical field of planting woody medicinal materials, in particular to a cultivation method for high-quality and high-yield ginkgo for ground leaves in low mountains and hills. Background technique [0002] Ginkgo biloba is a deciduous tree of the genus Ginkgo in the Ginkgo family. It is a rare tree species relict from the Mesozoic Era and is known as a "living fossil". Ginkgo biloba is a special product in my country, and it is an economic forest that integrates raw materials such as fruit, medicinal materials, beverages, and wood, as well as environmental beautification and greening. [0003] The current distribution of ginkgo in my country accounts for more than 70% of the global total, and it is the world's largest producer of ginkgo leaf extract. In recent years, domestic ginkgo leaf extraction companies, ginkgo preparation companies and health care product companies are still increasing, and the demand for ginkgo le...
