磷、钾肥与 PP333配施对沟叶结缕草活性氧代谢和膜脂过氧化反应的影响
Effects of Combination of Phosphorus,Potassium Fertilizer and Paclobutrazol(PP333)Application on Active Oxygen Metabolism and Membrance Lipid Peroxidation of Zoysiagrass matralla
摘要
Abstract
The study on the effects of combination of phosphorus,potassium fertilizer and paclobutrazol (PP333)application on active oxygen metabolism and membrance lipid peroxidation of (Zoysia matrella)was done using a split-split-block field design.The results showed that it is significantly increased the activities of antioxidant enzymes of SOD,POD and CAT,whereas MDA content obviously decreases,the variation tenden-cy of PMP and LOX activity kept the same with MDA content .as a result,the peroxidation of membrane lipid was reduced,Hence the growth,cold-resistance ability.Morphological indexes of turfgrass density、plant height as well as chlorophyll which improved the leaves colour,were significantly increased.The landscape quality of turfgrass was improved during winter in the end.It was demonstrated that there was positive interac-tion among phosphorus,potassium fertilizer and paclobutrazol(PP333 )application.An optimum formula is proposed based on comprehensive analysis of the indexes,the optimum combination of phosphorus,potassium and paclobutrazol(PP333 ) was obtained,which was P2K3Y2 (P2 O5 :60 kg /hm2 ;K2 O:140 kg /hm2 ;pa-clobutrazol(PP333):250 mg /L).关键词
