春小麦是我省粮食作物之一,其生理特点是生长期短,吸肥早,吸肥快,针对其生理特点进行合理施肥,确定施肥时期及用量等已有过不少报道。特别是对氮肥的施用时期及用量研究资料更多;但对氮、磷、钾三要素的配合使用,以及三要素间的比例搭配对春小麦的生长发育和产量影响方面的资料较少。为了找出适合我省自然地理环境和土壤条件下春小麦生长发育和高产的氮磷钾最佳配比于1981、1982年布置了盆栽试验。 Spring wheat is one of the grain crops in our province. Its physiological characteristics are short growth period, early absorption of fat, fast absorption of fat, rational fertilization according to its physiological characteristics, determination of fertilization period and dosage, etc. There have been many reports. In particular, there are more data on the application period and amount of nitrogen fertilizer. However, there are few data on the combination of three elements of nitrogen, phosphorus and potassium and the proportion of three elements on the growth and yield of spring wheat. In order to find out the optimal ratio of NPK for the growth and development of spring wheat and the yield of spring wheat suitable for the natural geographical environment and soil conditions of our province, the pot experiment was arranged in 1981 and 1982.
