| 摘 要： | 用 95 0 2 1和鲁麦 2 1两个小麦品种进行了灌水和肥料试验 ,每个品种设常规拔花二水、拔孕二水、深施磷拔花二水、深施磷不灌水和不深施磷不灌水共 5个处理。结果表明 :a .深施磷抑制 1 40厘米以下层次的根系发育 ;b .灌拔花两水条件下 ,深施磷对鲁麦 2 1有效果 ,对95 0 2 1的产量没有影响 ,在不灌水条件下 ,深施磷对两个品种均有增产效果 ;c) .拔孕二水与拔花二水相比 ,前者减产。

| Abstract: | Different P fertilization and irrigation treatments were applied to two wheat varieties, 95021 and Lumai 21. The treatments were: Irrigation at feeks stage 7 (stem extension) and feeks stage 10.5 (flowering), Irrigation at feeks stage 7 and feeks stage 10 (booting), Irrigation at feeks stage 7 and feeks stage 10.5 with deep phosphorus application before sowing, no irrigation after seeding with deep phosphorus application, and no irrigation after seeding and no deep P application. The main results were: a. Deep application of phosphorus restricted root development in soil profile 140cm under soil surface; b. With two irrigations at feeks stage 7 and 10.5, deep P application improved yield of Lumai 21 and had no influence on yield of 95021; With no irrigation, deep P application improved the yield of both varieties; c. Irrigation at feeks stage 7 and 10 reduced the yield of both varieties compared with irrigation at feeks stage 7 and 10.5. |
