Problems solved by technology

Furthermore, the height of the plant is not conducive to the later picking of leaves.
At present, in the cultivation of ginkgo for leaves, it is generally cut off once at a high position when the seedling age is 6 to 7 years, and the height of the stem is 50 to 60 cm. Give full play to the characteristics of the growth of the middle and lower leaves of Ginkgo biloba, while the new shoots are still in the upper part and grow slowly

Embodiment 1

[0029] Yancheng Jiayou Agricultural Technology Co., Ltd. has more than 4,000 mu of ginkgo for leaves. It was planted and raised in 2013. The density of seedlings per mu was 25,000 to 30,000 plants in that year. From 2014 to 2015, the density of seedlings per mu was adjusted to about 4,000 plants. In the winter of 2016, the 100 mu ginkgo field in the planting base of Longgang Town, Yandu District of the company adopted the technology of truncating, leaving 30cm dry after truncating, and using compound fertilizer (15N-15P 2 o 5 -15K 2 O) 100kg. In the spring of 2017, 3 to 4 new branches appeared, and the growth of the year was more than 50cm. In October 2018, 75kg of compound fertilizer and 15kg of phosphate fertilizer were applied to promote growth. In winter, the branches were cut off, and the length of the remaining branches was about 5cm. The content of flavonoids in ginkgo leaves was determined. 1.02%, while the flavonoid content of uncut seedlings in the same period was ...

Abstract

The invention discloses a shrub-like cultivation method of ginkgo biloba. The method specifically comprises steps as follows: (1) planting land preparation; (2) nursery stock cultivation; (3) main stem cutting; (4) germination acceleration; (5) branch cutting; (6) follow-up management. According to the shrub-like cultivation method of ginkgo biloba, the length of the branches is controlled at about 1.5 m, leaf harvesting is facilitated, and the labor intensity is reduced. The content of flavone in newly growing branch leaves is 5% higher than that of branch leaves growing for 5-6 years or longer, the value of the leaf products is high, and the sale income is good. Further, branches obtained after intermediate cutting can be applied as biomass fuel.

Description

technical field [0001] The invention belongs to the field of horticultural cultivation methods, and in particular relates to a ginkgo shrub cultivation method. Background technique [0002] Ginkgo (scientific name: Ginkgo biloba L.) is a deciduous tree of the Ginkgo family and the genus Ginkgo. The initial cultivation of Ginkgo was mainly for greening and ornamental, and later it developed into a dual-purpose fruit and then developed into a cultivation method based on fruit picking. The special value of ginkgo leaves has led to the emergence of a new cultivation method based on picking leaves. The cultivation method of picking leaves is "short, dense, early, and abundant". It is necessary that the ginkgo plants should not grow infinitely high. content is relatively high. For this reason, in order to facilitate leaf picking and improve leaf quality, ginkgo plants need to be dwarfed and cultivated. It is necessary to change the main stem-based growth mode of ginkgo biloba int...
