| 摘 要： | 着重探讨了南方不同生态类型圩区农田埋设塑料暗管对小麦地上部分矿质营养吸收、干物质累积和分配、产量及品质的影响。试验结果表明：农田埋设塑料暗管排水能显著提高麦株地上部分对Ｎ、Ｐ,Ｋ矿质营养元素的吸收,促进小麦各生育期尤其是拔节孕穗期地上部分干物质累积,小麦增产幅度达到２０．３％￣５３．３％,并能提高籽粒蛋白质和氨基酸含量,改善小麦籽粒的品质。 |
| 关 键 词： | 塑料暗管 养分 干物质产量 小麦 暗管排降 肥料 |

| Abstract: | The effects of PVC subdrainage on the mineral nutrient uptake,dry matter accumulation as well as distribution,yield and quality of winter wheat in different ecological polder areas of Nanjing are discussed.The results show that field PVC subdrainage could significantly increase the uptake of N.P.K elements and facilitate dry matter accumulation during all growth and development stages especially the jointing and booting stage,the grain yield increment ranging from 20.3% to 53.5%.Moreover,PVC subdrainage could also improve grain quality through increasing the contents of protein and amino acids. |
| Keywords: | PVC subdrains nutrients dry matter yield quality winter wheat |
