Embodiment 1
[0069] Embodiment 1 field verification test
[0070] Field experiments showed that using this method to fertilize Chinese cabbage was recommended, reducing the amount of nitrogen and phosphorus fertilizers, appropriately increasing the amount of potassium fertilizer, ensuring or increasing the yield of cabbage, and reducing the nitrate content of cabbage.
[0071] The tests were carried out in Zhangziying Town, Weishanzhuang Town, Daxing District, Beijing, and the experimental base of the Institute of Agricultural Sciences, Shunyi District. Before planting cabbage, formulate a survey table to investigate the planting information of each experimental plot, obtain the yield of cabbage under the conditions of farmers' customary fertilization, and the specific type, amount and method of fertilization, determine the target yield of cabbage in the plot, and calculate the yield of the plot. The nitrogen, phosphorus and potassium yield response of cabbage planting makes recommendation...
