| 摘 要： | 通过2种播种方式不同灌水次数处理,发现地膜小麦比露地小麦花后5～41d籽粒鲜重平均高2.3g/千粒,千粒重高2.11g/千粒,籽粒干重日增长量高0.173g/千粒·日。不灌水处理籽粒灌浆过程比灌1水、2水、3水缩短3～4d,比灌4水处理缩短7～8d。花后5～41d,灌浆速率大小顺序为4水>3水>2水>1水>0水。水分胁迫促使小麦籽粒灌浆进程加块,时间缩短,千粒重降低。

| Abstract: | Through comparision of different irrigating number of two kind sowing-seed patterns, results showed:compared with outdoor wheat, from the fifth day to the forty-first day after blooming, fresh weight of plastic mulching wheat could increase 2. 3 g/1000 grains on the average, 1000-kernel weight can increase 2. 11 g/1000 grains, kernel dry weight can increase 0. 173 g/1000 grains. Compared with 1-times irrigation , 2-times irrigation and 3-times irrigation respectively kernel filling period could decrease 3~4 days; compared with 4-times irrigation, it could decrease 7~8 days. From the fifth day to the forty-first after flooming, the filling speed systematic arrangement was 4-times irriga-tion>3-times irrigation>2-times irrigation >l-times irrigation >unirrigation. Water stress can accelerate wheat kernel filling speed,shorten its period and reduce 1000-kernel weight. |
