【摘要】：以當(dāng)?shù)匦←溒贩N新原958為對象,在孕穗期和灌漿期分別進行1、3、5和7 d的淹水處理,并以當(dāng)?shù)爻Ｒ?guī)灌溉處理為對照(CK)在測坑中進行受澇試驗,觀察和分析了澇害對冬小麥生長和產(chǎn)量的影響。結(jié)果表明,孕穗期和灌漿期淹水處理對小麥葉綠素、灌漿速率和產(chǎn)量有一定的抑制作用,且隨著淹水歷時的增加,抑制作用越明顯。與CK相比,孕穗期淹水7 d(wb7)處理的葉綠素顯著降低了16.64%,籽粒灌漿速率降低了95.02%,產(chǎn)量降低29.6%,千粒質(zhì)量降低了6.15%;灌漿期淹水7 d(wg7)處理的產(chǎn)量較CK減產(chǎn)25.9%。孕穗期和灌漿期淹水處理都會造成小麥減產(chǎn),尤其是孕穗期淹水處理。因此,在小麥生產(chǎn)的日常管理中,應(yīng)及時采取排水措施,以免造成小麥減產(chǎn)。
[Abstract]:The local wheat variety Xinyuan 958 was treated with flooding at booting stage and grain filling stage for 1 and 7 days, respectively. The waterlogging test was carried out in the pit with local routine irrigation treatment as control. The effects of waterlogging on the growth and yield of winter wheat were observed and analyzed. The results showed that flooding at booting stage and grain filling stage inhibited wheat chlorophyll, grain filling rate and yield to a certain extent, and the inhibition was more obvious with the increase of flooding duration. Compared with CK, the chlorophyll content, grain filling rate, grain yield and grain weight were significantly decreased by 16.64%, 95.02%, 29.6%, 6.15% and 25.9% respectively. Flooding at booting stage and grain filling stage can cause wheat yield reduction, especially in booting stage. Therefore, in the daily management of wheat production, drainage measures should be taken in time to avoid wheat production reduction.
