Broadcast sowing increased the transport amount of nitrogen stored at pre-anthesis in sheaths, and later sowing date decreased the N transport amount stored at pre-anthesis in all vegetative organs, while the N transport rate stored at pre-anthesis showed different trends in different organs.

撒播显著提高了茎和叶鞘中花前氮素运转量，各营养器官的花前积累氮素的运转量随着播期的推迟逐渐降低，而花前积累氮素的运转率则因器官的不同呈现不同规律。

The leaf area index ( LAI) was higher at booting and anthesis stage under the treatment with early sowing date and large sowing quantity in broadcast sowing ( SD1Q3 and SD2Q3). while decreased rapidly after anthesis.

较早播种大播量的撒播（SD1Q3或SD2Q3）小麦在孕穗期及开花期时具有较大的叶面积指数（LAI），但在开花后其LAI却迅速下降。
