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.
