Problems solved by technology

[0005] Some problems will inevitably be encountered in the process of ginkgo industrialization: due to the large output of ginkgo leaves, a large amount of nutrients will be lost, resulting in the interruption of nutrient cycle and the decline of soil fertility, and the productivity cannot be maintained. Very large tree species must rely on artificial nutrition to increase the economic output of ginkgo leaves, otherwise they will not be able to sustainably develop
[0006] At present, although domestic and foreign studies on ginkgo fertilization technology and mineral nutrition have achieved certain results, most of them stay on the impact of fertilization on ginkgo growth indicators, and there is not enough research on the impact on ginkgo leaf quality, especially on the flavonoid content. Only a few people have studied

Embodiment 1

[0033] 1. Fertilize according to the following formula:

[0034]

[0035] 2. Fertilize according to the following steps:

[0036] 1) On March 29, 2007, a ditch was dug around the ginkgo tree with a depth of 15cm and a width of 20cm. Each takes 1 / 3 of the total amount of nitrogen, phosphorus and potassium fertilizers in the above formula, spreads them evenly in the small ditch, and then covers them with ditch soil;

[0037] 2) On May 20, 2007, the second root fertilization was performed according to the same fertilization amount and fertilization method on March 20;

[0038] 3) On May 27, each solution was prepared according to the concentration of magnesium, zinc, and molybdenum, and the three equal amounts were mixed and sprayed on the leaves of Ginkgo biloba with a sprayer;

[0039] 4) On June 12, fertilize the leaves again with the same amount of magnesium, zinc and molybdenum solutions as described on May 27;

[0040] 5) On June 27, apply the same amount of magnesium...

Abstract

The invention relates to a ginkgo fertilizer and a fertilizing method thereof, which can obviously improve the root system activity, the single leaf area, the chlorophyll concentration, the photosynthetic rate and the leaf yield of a ginkgo. The ginkgo fertilizer comprises foliar fertilizer, wherein the foliar fertilizer comprises Mg, Zn and Mo, the mass ratio of which is 0-3.0:0.10-0.50:0.05-0.20. As an improvement, the ginkgo fertilizer also comprises root fertilizer, wherein the root fertilizer comprises N, P and K the mass ratio of which is 1.6-6.4:0-3.2:1.6-3.2. The fertilizing method ofthe ginkgo fertilizer comprises the following steps: respectively preparing the Mg, the Zn and the Mo in the foliar fertilizer into a solution with the concentration of 0-3.0 percent, a solution withthe concentration of 0.10-0.50 percent and a solution with the concentration of 0.05-0.20 percent; and applying same doses of the three solutions with equal content to the leaf surfaces total three times since the end of May, wherein the fertilizing interval is 15 days. The leaf surface fertilizing method is matched with the public known root fertilizer fertilizing method.

Description

technical field [0001] The invention relates to a ginkgo fertilizer and a fertilization method thereof, belonging to the technical field of economic forest cultivation and fertilization. Background technique [0002] Ginkgo biloba (Ginkgo biloba.L.), also known as ginkgo, duck foot tree or Gongsun tree, is a single species of plant. It has lived on the earth for 170 million years. It has the reputation of "living fossil" and is a unique relic plant in China. . It integrates food, material, landscape, ecological protection, medicine and health care, and is a precious economic tree species. [0003] Ginkgo is full of treasures. Although the medicinal and health benefits of ginkgo were recognized very late, ginkgo medicines and health products have been favored since the 1980s. Studies have shown that its medicinal ingredients are mainly flavonoids and lactones, and these two active ingredients are mainly concentrated in the leaves. In addition, the leaves also contain 17 ki...
