Embodiment 1
[0073] Example 1 Field verification test
[0074] The experiment was carried out in Tianjin, Shandong, and Beijing in spring and autumn of 2018. 4 experimental sites were arranged in each region in spring and autumn, and there were 24 field trials in three regions in two seasons.
[0075] Before radish planting, the planting information survey was conducted on each test plot to obtain the farmers’ past years’ radish output, fertilization amount, and fertilization method, etc., to determine the target yield of radish and the level of soil basic nutrient supply.
[0076] The recommended fertilization method (NE) was used to calculate the yield response and the amount of N, P, and K fertilizer (see Table 5), and the farmers’ habitual fertilization treatment (FP) and soil testing fertilization treatment (ST) were set as controls.
[0077] The area of each plot is guaranteed to be 20-30m 2 , Each treatment is repeated 3 times.
[0078] Specific steps are as follows:
