Technical Field

The invention belongs to the technical field of gingko planting, and particularly relates to a method for improving the yield of gingko leaves.

Background

Ginkgo biloba (Ginkgo biloba L), also known as Ginkgo tree, is a plant in the genus of Ginkgoaceae, is a wiggerian that survives on earth in glacier, and is called "activating stone".

With the increasing population of the world, the production of crops by using limited land resources is a difficult task, and how to improve the yield of ginkgo leaves faces a huge challenge.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the technical problems, the invention provides a method for improving the yield of ginkgo leaves.

The technical scheme is as follows: in order to achieve the purpose of the invention, the technical scheme adopted by the invention is as follows:

a method for increasing the yield of ginkgo leaves comprises the following steps:

(1) selecting flat ground or gentle slope ground as seedling ground;

(2) the number of plants is 20-100/m²Transplanting the ginkgo seedlings at the density;

(3) during the growth period of the gingkoes, different management methods are adopted according to different seasons;

(4) the base fertilizer is a slow-acting organic fertilizer, and is matched with a nitrogen-phosphorus compound fertilizer, and the spring fertilizer is topdressed twice.

Preferably, the method comprises the following steps:

in the step (1), a section with flat terrain, good drainage, deep and fertile soil, and convenient irrigation and traffic is selected as a seedling land.

In the step (1), the gradient of the gentle slope land is less than 3 degrees.

In the step (1), the soil quality of the seedling field is sandy loam or loam.

In the step (2), the ginkgo seedlings are 2-year-old ginkgo seedlings.

In the step (3), different management methods are adopted according to different seasons, and the method comprises the following steps:

the soil is loosened in spring to improve the ground temperature, in summer and rainy season, the soil is loosened in time, the soil ponding is dissipated, the ground temperature is reduced, and the soil is loosened in autumn to eliminate overwintering pests and weeds.

In the step (4), the slow-acting organic fertilizer is selected from a group consisting of a miscellaneous fertilizer, a green manure, an animal manure, a human and livestock manure or a cake fertilizer.

In the step (4), the spring fertilizer is quick-acting nitrogen fertilizer and phosphate fertilizer.

In the step (4), the spring fertilizer additional application is selected from 3 months and 5-6 months.

Has the advantages that: compared with the prior art, the invention has the following advantages:

(1) the method is convenient to operate, simple and feasible, and suitable for popularization in production.

(2) Compared with the existing ginkgo planting density, the ginkgo leaf flavonoid ingredient of the ginkgo leaf slices with the increased planting density is slightly reduced, but the plants with the increased planting area are higher, the growth state is better, and the dry fresh weight of leaves, the leaf area and the number of leaves of a single plant are obviously increased. The overall yield is significantly improved.

(3) The method can improve the utilization rate of the land in unit area and save land resources.
