丘陵旱地小麦完全依靠天然降水,如何合理施肥,充分发挥肥效,以肥调水,便成为夺取小麦高产的重要问题。为探索旱农条件下施用氮磷化肥配合的肥效及其经济效益,我们于1982—1983年在伊川县白沙公社范村大队科研站进行小麦氮磷化肥配比及最佳经济施用量的试验。
Hilly dryland wheat relies entirely on natural precipitation, how to apply fertilizers reasonably, give full play to the effect of fertilizers, and adjust the water with fertilizer to become an important issue to seize the high yield of wheat. In order to explore the fertilizer efficiency and its economic benefits of nitrogen and phosphorus fertilizers application under dry and agricultural conditions, we conducted experiments on the ratio of nitrogen and phosphorus fertilizers and the optimal economic application of wheat nitrogen and phosphorus fertilizers at the research station of Fancun Brigade, Baisha commune, Yichuan County from 1982 to 1983.
