Problems solved by technology

[0003] Ginkgo trees grow slowly, have a long lifespan, and are extremely sensitive to the ecological environment. The long-term fertilization method is to spread a certain amount of farm manure or a little cake fertilizer around the trunk on New Year's Eve. Disadvantages such as single, improper fertilization methods and application periods, etc., with the passage of time and the increase of ginkgo yield, the contradiction between the supply and demand of various nutrients in the ginkgo rhizosphere soil has become more and more prominent, and the phenomenon of "big and small years" in ginkgo yield has also intensified. Therefore, How to improve fertilizer nutrients, increase the technical content of ginkgo fertilization technology, and better coordinate ginkgo nutrition have become the top priority for the stable development of ginkgo production

Embodiment

[0019] A method for planting and cultivating ginkgo trees, comprising the following steps: firstly, in the ginkgo planting area, for five consecutive years, in mid-October every year, after the ginkgo is harvested, extensively collect soil samples from the plow layer for laboratory analysis, and touch Clear the nutrient status of phosphorus, potassium, zinc, boron, silicon and other trace elements in the ginkgo production area, so as to grasp the first-hand soil nutrient data, and provide a scientific basis for the development of ginkgo soil testing and formula fertilization.

[0020] According to the types of ginkgo trees, ginkgo trees are divided into two types: fruit-producing type and leaf-picking type. As far as the three nutrients of N, P, and K are concerned, ginkgo trees have different requirements for nutrients in different growth periods. .

[0021] In terms of the overall growth trend of ginkgo trees, divided according to seasons, (1) In spring, due to the large gro...

Embodiment 2

[0029] All the other are the same as Example 1, the difference is that the fertilizer is a powdery structure, wherein the total nutrient (N+P 2 o 5 +K 2 O) ≥ 40%, moisture content ≤ 2%, medium and trace elements (Zn+Mn+Cu+Mo+Fe, etc.) ≥ 1%, PH value between 6-8, put the fertilizer into a bag and bury it until The root of the ginkgo tree, through contact with water, gradually dissolves and is fully absorbed by the root of the ginkgo tree.

Abstract

The invention discloses a method for culturing and planting gingko trees and relates to the technical field of agricultural planting. The method for culturing and planting the gingko trees comprises the following steps: (1) testing the effective contents of high, medium and trace amounts of elements such as nitrogen, phosphorus, zinc, boron, and silicon in the soil in the planting area of the gingko trees; (2) applying a composite fertilizer with a total content of nutrients of greater than or equal to 40% to the gingko trees according to the tree ages of the gingko trees, and adjusting a ratio of N to P to K according to the different ages of the gingko trees; and (3) applying the fertilizer to the gingko trees in April, July and October in every year respectively and determining the fertilizer applying amount according to the diameter of the crown. By virtue of the technical scheme, the inner nutritional ingredients of the gingko trees can be effectively adjusted, so that the yield of the surrounding gingko trees is relatively consistent and tends to the high yield.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for planting ginkgo trees. Background technique [0002] Ginkgo biloba is a deciduous tree belonging to the Ginkgo family and the genus Ginkgo. It is also known as ginkgo, gongsun tree, duck foot tree, and cattail leaf fan. It is the oldest relict plant among the existing seed plants. Ginkgo biloba is one of the most precious tree species in the world. It is regarded as a "living fossil" in the plant world. It has ornamental, economic and medicinal values. Its stems, kernels, outer testa, leaves, etc. have a wide range of uses , especially has good nutritional value and medicinal value to humans. [0003] Ginkgo trees grow slowly, have a long lifespan, and are extremely sensitive to the ecological environment. The long-term fertilization method is to spread a certain amount of farm manure or a little cake fertilizer around the trunk on New Year's Eve. Disadvantag...
