Abstract：The grain filling characteristics of winter-wheat in 5 tillage patterns were studied using the cultivar Kenong 9204 in wheat-maize double cropping system of North China Plain .The result indicated that the tillage patterns effected 1 000-weight remarkably .The grain filling law of winter-wheat was consistent with the logistic function in different tillage patterns ,and the tillage patterns effected the grain filling parameters .The maximum grain filling rate and the fastest-period filling rate were the most important factors to grain weight .The filling dates and filling rate in no-tillage with maize-stalk crushed for mulching and no-tillage with whole maize-stalk mulch were less than those in other three tillage patterns ,the difference being significant at 0.05 level compared with the “plow-tillage with maize-stalk crushed and returned to field” .
