山东、河南、河北三省小麦氮、磷与锌配合施用田间试验结果：氮、锌配合施用效果好于单施氮和单施锌，其中，以氮肥效果为主，锌肥也有明显效果，氮、锌配合比例以每公顷Ｎ１１２．５－１８７．５公斤，硫酸锌１５－３０公斤最好；磷、锌配合施用效果好于单施磷和单施锌，磷、锌配合比例以每公顷Ｐ２Ｏ５５６．３－１１２．５公斤，硫酸锌１５－３０公斤效果好。氮、磷、锌配合施用盆栽试验结果：以每公顷Ｎ１８７．５公斤、Ｐ２Ｏ５５６．３公斤、硫酸锌６０公斤配合施用产量最高，而氮素利用率以３０公斤硫酸锌为优。综合田间试验结果和盆栽试验结果，北方潮土、砂姜黑土上种植小麦，每公顷面积比较经济合理的氮、磷、锌配合施用比例是：Ｎ１１２．５－１８７．５公斤，Ｐ２Ｏ５５６．３－１１２石公斤，硫酸锌１５－３０公斤。
The results of field experiments showed that nitrogen and zinc were better than single nitrogen and single zinc in the combination application of nitrogen, phosphorus and zinc in Shandong, Henan and Hebei provinces. The main effect of nitrogen fertilizer was zinc fertilizer, and nitrogen, The proportion of zinc is the best in the range of N112.5-187.5 kg per hectare and 15-30 kg of zinc sulfate. The application efficiency of phosphorus and zinc is better than that of single phosphorus and single phosphorus, phosphorus and zinc in the ratio of P2O556 per hectare. 3-112.5 kg, zinc sulfate 15-30 kg good effect. The result of pot experiment with N, P and Zn: The yield of N187.5kg / h, P2O556.3kg / kg and 60kg / h were the highest, while the nitrogen utilization rate was better in 30kg of zinc sulfate. According to the results of field experiment and pot experiment, the proportion of nitrogen, phosphorus and zinc fertilizer applied per hectare is N112.5-187.5 kg and P2O556.3- 112 stone kilograms, 15-30 kilograms of zinc sulfate.
