中文摘要	2004年9月到2005年7月在河西绿洲地区结合田间试验对不同灌溉处理下冬小麦品种繁17的籽粒灌浆特性进行了研究,研究结果表明:小麦籽粒灌浆规律符合"慢-快-慢"的"S"型生长曲线,可以为一元非线性回归方程很好的模拟;水分对籽粒灌浆和粒重有较大的影响,等量不等次的灌水处理(T2、T4、T5)相比,灌水次数愈少小麦灌浆起步时间愈早,达到峰值的时间越快,全生育期只灌2水的处理(T2)达到最大灌浆速率的时间为花后第16天,而灌3水处理(T4、T5)的灌浆速率达到峰值的时间为花后第22天;等次不等量的灌溉处理 (T3、T4、T5)相比,平均灌浆速率随灌溉量的增加而增大,T3灌溉量最大,其平均灌浆速率分别高于T4、T55.39%、6.02%;整个灌浆期平均灌浆速率、灌浆持续天数与产量、千粒重均呈正相关,平均灌浆速率与产量、千粒重的相关系数分别为0.704、0.721,灌浆持续天数与产量、千粒重的相关系数分别为0.568、0.615
英文摘要	Based on field experiments,the grain filling characteristics under different winter condition of winter wheat Fan-17 were studied in Hexi oasis area. The results indicated that the grain filling regulation accorded with "S"growth curve of "slow-fast-slow",which could be simulated by monadic nonlinear regression equations water has great effect on grain filling and grain weight, compared with irrigation treatments of equal quantity-unequal times(T_2 ,T_4 ,T_5) ,the less the irrigating times,the earlier the wheat filling commence,the quicker the filling reach peak value,filling rate of T_2 which irrigated twice in whole growth stage reach peak value after 16 days of anthesis,T_4 ,T_5 which irrigated three times reach filling peak value after 22 days of anthesis;among treatments of equal times-unequal quantity,the average filling rate was increasing with the increase of irrigation quantity, the average filling rate of T_3 which irrigated the most respectively higher 5.39 %, 6. 02 % than T_4, T_5; the average filling rate had positive correlation with yield (0. 704) and weight of 1000 grains(0. 721),and the correlation coefficient of the filling duration days and yield,weight respectively were 0,568,0. 615.
