不同防寒技术处理对大花树状月季生理生化指标的影响

为研究不同防寒技术处理的抗寒效果,对南阳地区大花类树状月季设置树体修剪处理、土壤冬灌处理、施用磷钾肥处理、3种方式同时采用的处理、空白处理共5个防寒处理,并对各处理的相关抗寒生理生化指标进行测定。结果表明:各防寒处理其抗寒效果由高到低依次为:3种方式同时采用的处理、施用磷钾肥处理、树体修剪处理、土壤冬灌处理、空白处理。3种方式同时采用的处理其防寒效果与施用磷钾肥处理间差异不显著,但与其它3个处理间差异极显著。3种方式同时采用的处理和施用磷钾肥处理均可有效地保证大花类树状月季安全越冬,适合进行农业技术推广。其他3种独立的防寒处理中,施用磷钾肥处理抗寒效果最佳,其次是树体修剪处理,最后是土壤冬灌处理。

Effects of different cold protection treatments on physiological and biochemical indexes of tree rose with big flowers

In order to study cold protection effect of different cold protection treatments,some related physiological and biochemical indexes of tree rose with big flowers were determined under five cold protection treatments in Nanyang region,including tree pruning,soil irrigation in winter,applying P and K fertilizers,adopting three methods at the same time,and CK.The results showed that based on cold protection effect f~m high to low,the order of five treatments was adopting the three methods at the same time,applying P and K fertilizers,tree pruning,soil irrigation in winter,CK.Cold protection effect of adopting three methods at he same time had no significant differences with that of applying P and K fertilizers,but had significant differences with the other three treatments.Therefore,both adopting three methods at he same time and applying P and K fertilizers could effectively ensure safe wintering of tree rose with large flowers,and they were suitable for agricultural technology promotion.The other three independent cold protection treatments,applying P and K fertilizers had the best effect of cold protection,tree pruning was the second,and soilirrigation in winter had the worst effect.
