Description

Technical Field

[0001] The invention belongs to the field of plant planting, and particularly relates to a fertilization method for improving the yield of golden chrysanthemum. Background Art

[0002] Chrysanthemum morifolium is an important economic crop, which has attracted wide attention due to its high medicinal and health value. Traditional fertilization usually uses chemical fertilizers, but this method not only meets the needs of crop growth, but also brings a series of problems.

[0003] Traditional fertilizers release nutrients slowly and cannot meet the nutritional needs of golden chrysanthemum at different growth stages. Especially in key growth stages, such as the branching and bud formation stages, insufficient nutrients in the soil may limit plant growth, thus affecting the final yield and flower quality. In addition, conventional fertilization methods can easily lead to nutrient loss, especially in rainy seasons, causing eutrophication of water bodies and affecting the ecological environment. Excessive use of fertilizers may also lead to soil acidification and reduce the long-term production capacity of the soil.

[0004] As a new type of fertilizer, water-soluble organic fertilizer has many advantages and can effectively overcome the defects of traditional fertilization methods. In current agricultural production, there have been some studies on the application of water-soluble fertilizers on other crops, but the application method of water-soluble organic fertilizers for golden chrysanthemum needs further exploration and optimization. Different growth environments, soil conditions and cultivation management measures will affect the growth and fertilizer absorption of golden chrysanthemum. Therefore, studying a method for applying water-soluble organic fertilizers suitable for the growth characteristics of golden chrysanthemum is of great practical significance for increasing its yield, improving quality, reducing production costs and promoting sustainable agricultural development.

[0129] According to the data in Table 1, the golden chrysanthemum planted by the fertilization method defined in the present invention has a certain degree of improvement in plant height, stem thickness, number of leaves, leaf length and leaf width compared with other fertilization methods.

[0130] Comparing Example 1 with Examples 4-5, it can be seen that the amount of water-soluble organic fertilizer used has a significant effect on the agronomic traits of Golden Chrysanthemum, and too high or too low an amount of water-soluble organic fertilizer is not conducive to improving the agronomic traits of Golden Chrysanthemum. Comparing Example 1 with Examples 6-10, it can be seen that the use of other fertilizers in different growth stages of Golden Chrysanthemum can further improve the agronomic traits of Golden Chrysanthemum. Furthermore, the use of water-soluble organic fertilizers in combination with specific fertilizers at different stages can more effectively improve the agronomic traits of Golden Chrysanthemum.

[0131] Comparing Example 1 with Comparative Example 1, it can be seen that the application time of the water-soluble organic fertilizer has a significant effect on the agronomic traits of Goldenrod. Comparing Example 1 with Comparative Examples 2-3, it can be seen that the use of water-soluble organic fertilizers can significantly improve the agronomic traits of Goldenrod compared to traditional fertilizers.

[0132] Test Example 2

[0133] This test example evaluates the economic traits of golden chrysanthemum planted by fertilization methods of Examples 1-10 and Comparative Examples 1-3, and the results are shown in Table 3:

[0134] The quality of golden chrysanthemum is scored according to the standards in Table 2. The quality of golden chrysanthemum is closely related to its economic value. The higher the quality of golden chrysanthemum, the more conducive it is to increasing the output value of golden chrysanthemum.

[0140] According to the data in Table 3, it can be seen that the fertilization method specified in the present invention can not only increase the per-acre yield of golden chrysanthemum, but also improve the quality of golden chrysanthemum, increase its average price, and thus obtain higher economic benefits.

[0141] Comparing Example 3 with Examples 4-5, it can be seen that the amount of water-soluble organic fertilizer has a significant effect on the economic traits of Golden Chrysanthemum, and too high or too low an amount of water-soluble organic fertilizer is not conducive to improving the economic traits of Golden Chrysanthemum. Comparing Example 1 with Examples 6-10, it can be seen that the use of other fertilizers in different growth stages of Golden Chrysanthemum can further improve the economic traits of Golden Chrysanthemum, and further, the use of water-soluble organic fertilizers in combination with specific fertilizers at different stages can more effectively improve the economic traits of Golden Chrysanthemum.

[0142] Comparing Example 1 with Comparative Example 1, it can be seen that the application time of water-soluble organic fertilizer has a significant effect on the economic traits of Goldenrod. Comparing Example 1 with Comparative Examples 2-3, it can be seen that the use of water-soluble organic fertilizer can significantly improve the economic traits of Goldenrod compared to traditional fertilizers.
