Abstract
In order to clarify the rational regulation of different water conditions and phosphorus supplied,a rain-proof pool culture experiment,including two water levels,i.e.,moderate soil water content(75%),water stress(55%),and three fertilizing levels,i.e.,P1(75 kg/hm2),P2(150 kg/hm2),P3(225 kg/hm2)was conducted.The results showed that the decreasing range of SOD、POD、CAT and arising range of MDA in P2 treament under W1 were lower than the other two after anthesis.The activities of SOD、POD、CAT increased and the content of MDA decreased with the increase of phosphorus.Therefore moderate phosphorus supplied under W1 and increasing phosphorus supplied under W2 could improve protective enzyme,increase leaf area index、chlorophyll content,and photosynthetic rate,delay the senescence,incease the yield.Though W2P2 achieved the highest yield,compared with W1P2,it had no siganificant difference.It was concluded that the treatment W1P2 was the better combination of water and fertilizer.
