| 摘 要： | 试验于１９９２年１０月至１９９４年６月在江苏农学院作物水分测坑进行，采用人工模拟方法，将地下水埋深分别控制在５０，９０，１３０，１７０ｃｍ，比较不同地下水埋深对小麦生长发育和产量的影响。研究表明：地下水埋深为１３０ｃｍ的小麦产量最高，其次为９０ｃｍ和１７０ｃｍ，５０ｃｍ的产量最低，从产量构成看，产量差异主要表现在每穗粒数和粒重两个方面；花后干物质生产以１３０ｃｍ最高，根系活力也以１３０ｃｍ最强。

| Abstract: | Modelling experiment from elongation stage to maturity of wheat with 4 underground waterlevels i.e. 50, 90,1 30 and 170cm, at Crop Water Plot of Jiangsu Agricultural College during October of1992 to June of 1994 indicated that 130cm was optical in terms of grain yield resulting from the greatest accu-mulated dry matter amount after anthesis and strongest root activity. The grain number per ear and grainwelght among treatrnents were significantly different. |
