Problems solved by technology

[0004] At present, the cultivation and planting of leaf ginkgo orchards are mainly seeds, cuttings and transplanting to build gardens. The planting density is 300-600 plants / mu, and the leaf production period of ginkgo is 6-8 years. The content of ginkgo leaves after that cannot meet its quality requirements.
The ginkgo leaves produced by traditional ginkgo cultivation for leaves cannot meet the growing demand for ginkgo leaves. Therefore, the application and promotion of high-quality and high-yield cultivation methods for ginkgo leaves are of great importance to the yield, quality requirements and economic benefits of ginkgo leaves. practical significance

Embodiment 1

[0024] A high-quality and high-yield leaf ginkgo cultivation method, the steps are as follows:

[0025] (1) Site preparation: select loam or sandy loam with deep soil layer, fertile and loose soil, and good drainage and irrigation conditions as the garden site. After the land is thawed in the spring of the planting year, use decomposed farmyard manure as the base fertilizer, the application rate is 3000kg / mu, plow the land 40cm deep, level the land, make a high bed with a width of 1.2m, a height of 10cm, and a ditch width of 30cm, and water it thoroughly. sowing.

[0026] (2) Seed treatment: 15 days before sowing, put the seeds in a container, stir continuously and add water until the seeds are covered by 8cm, rinse off the shriveled seeds, soak the seeds to soften the seed coat, and 75% of the seeds absorb water and swell after cracking fish out.

[0027] (3) Sowing: In March to April, the quality standard is 450 grains / kg ginkgo seeds are evenly sown on the high bed with a...

Abstract

The invention relates to the field of agricultural product plantation and specifically discloses a cultivation method for high-quality and high-yield leaf-oriented ginkgo. The method comprises the steps including land selection and preparation, seed processing, sowing, thinning, field management and harvesting. The method disclosed by the invention is characterized in that complicated processes of traditional seed cultivation and cutting seedling transplantation are reduced through direct sowing, and duration for first-time leaf production of the leaf-oriented ginkgo is shortened; through the periodic thinning, continuous growth and soil fertility supply of ginkgo trees are ensured, thinned seedlings can be re-transplanted for orchard establishment, land used for cultivation of ginkgo seedlings is reduced, and a land use rate is increased; and through rational close planting, the acre yield of the leaf-oriented ginkgo is increased, leaf production years of the ginkgo are prolonged, quality of ginkgo leaves is ensured, high economic benefits are obtained, and the method is applicable to promotion and plantation in Hubei Province.

Description

technical field [0001] The invention relates to the field of planting agricultural products, in particular to a method for cultivating high-quality and high-yield ginkgo for leaves. Background technique [0002] Ginkgo biloba (Ginkgobiloba L), also known as ginkgo tree and Gongsun tree, is one of the oldest relict plants in the existing seed plants in my country, and is called "living fossil". Ginkgo biloba is the dried leaf of Ginkgo biloba, which has the effects of promoting blood circulation and removing blood stasis, dredging collaterals and relieving pain, astringing the lungs and relieving asthma, and reducing turbidity and fat. According to analysis, Ginkgo leaves contain more than 60 chemical components such as flavonoids, biflavones, and mushrooms. The main extracts of ginkgo flavonoids and ginkgo lactone are good medicines for treating cardiovascular and cerebrovascular diseases and anti-platelet activating factors. [0003] With the continuous deepening of the un...
