Embodiment 1

[0024] Example 1, mix humic acid (provided by Xinjiang Shuanglong Humic Acid Co., Ltd.), urea (commercially available, urea containing N ≥ 46%), and potassium dihydrogen phosphate (commercially available) in a weight ratio of 2:1:1 , made into humic acid fertilizer powder. When applying, first add water to a smaller container to dissolve the humic acid fertilizer powder initially, then transfer the initially dissolved powder solution to a larger container and add water for secondary dissolution to ensure complete dissolution, and then apply drip irrigation to the roots Apply during the growth period of apples, the fertilization cycle is once a month, and the amount and method of each fertilization are consistent. In this example, application began in mid-April 2012, and then applied once every other month, for a total of 6 applications. The total usage is equivalent to: humic acid 70.3g / tree, N54.1g / tree, K 2 O40.0g / tree, P 2 o 5 61.2g / tree.

Embodiment 2

[0030] Example 2, mix humic acid (provided by Xinjiang Shuanglong Humic Acid Co., Ltd.), urea (commercially available, urea containing N ≥ 46%), and potassium dihydrogen phosphate (commercially available) in a weight ratio of 2.5:1:1.5 , made into humic acid fertilizer powder. When applying, first add water to a smaller container to dissolve the humic acid fertilizer powder initially, then transfer the initially dissolved powder solution to a larger container and add water for secondary dissolution to ensure complete dissolution, and then apply drip irrigation to the roots Apply during the growth period of apples, the fertilization cycle is once a month, and the amount and method of each fertilization are consistent. In this example, the application started in mid-April 2012, and was applied every other month thereafter, for a total of 6 applications. The total usage is equivalent to: humic acid 88.0g / tree, N59.6g / tree, K 2 O60.0g / tree, P 2 o 5 97.7g / tree.

Embodiment 3

[0031] Example 3, mix humic acid (provided by Xinjiang Shuanglong Humic Acid Co., Ltd.), urea (commercially available, urea containing N ≥ 46%), and potassium dihydrogen phosphate (commercially available) in a weight ratio of 1.5:0.5:1 , made into humic acid fertilizer powder. When applying, first add water to a smaller container to dissolve the humic acid fertilizer powder initially, then transfer the initially dissolved powder solution to a larger container and add water for secondary dissolution to ensure complete dissolution, and then apply drip irrigation to the roots Apply during the growth period of apples, the fertilization cycle is once a month, and the amount and method of each fertilization are consistent. In this example, application began in mid-April 2012, and then applied once every other month, for a total of 6 applications. The total usage is equivalent to: humic acid 52.8g / tree, N27.1g / tree, K 2 O40.0g / tree, P 2 o 5 61.2g / tree.

Abstract

A humic acid fertilizer preparation and a method for controlling apple tree rot diseases thereof. The humic acid fertilizer preparation is solid water-soluble powder formed by mixing humic acid and fertilizers. The method for controlling apple tree rot diseases by using the humic acid fertilizer preparation comprises: firstly dissolving the humic acid fertilizer preparation in water, and then applying the solution to roots of fruit trees by drip irrigation. According to the invention, humic acid is mixed with fertilizers to prepare the humic acid fertilizer preparation, and a drip irrigation mode is adopted for apple tree application in the growth period; the nutrition is enhanced; the absorption and utilization of nutrients by fruit trees are improved; the preparation enables fruit trees to grow healthily and strongly, enhances the tree vigor, and effectively reduces the incidence of apple tree rot diseases.

Description

technical field [0001] The invention belongs to the technical field of fertilizers for preventing and controlling fruit trees, and relates to a humic acid fertilizer preparation, and also relates to a method for using the fertilizer preparation to prevent and control apple tree rot. Background technique [0002] Humic acid, also known as humic acid (HA for short), is a mixture of a group of amorphous acidic substances with aromatic structures and similar properties, including black humic acid, fulvic acid and brown humic acid. It is often used as an abbreviation for humic acid substances. It was first discovered by the Germans in 1786. So far, the research and utilization of humic acid has a history of more than 200 years (Wang Zhonghe et al. Application of humic acid in fruit production [J]. Northwest Horticulture, 2010 (08): 38- 40). The development and application of humic acid in my country began in 1953, and it was used as a fertilizer in agricultural production. Aft...
