摘要：

在喷施钙基复合多聚体后细胞壁表面和胞间层都填满了试剂,可以显著改变猕猴桃越冬性能。猕猴桃枝条剪口及伤口不结冰、不冻融,减少了交替冻融创伤,田间发病率不超过2.18%,预防效果不低于84.5%。在复合多聚体中添加Cu(OH)2预防效果更好,喷施1次的发病率和预防效果分别为1.34%、90.5%,喷施2次的发病率和预防效果分别为0.96%、93.1%。感病植株喷施添加Cu(OH)2的钙基复合多聚体3个月后的净光合速率、气孔导度、蒸腾速率和总叶绿素含量分别比喷施1个月上升48.1%、57.3%、24.8%、69.9%,胞间CO2浓度降低16.0%。出现白色菌脓时可以喷施添加Cu(OH)2的钙基复合多聚体治疗,治愈率不低于87.5%。

Abstract:

The cell wall surface and intercellular layer were filled with reagents after spraying calcium based composite polymer, which could significantly change the overwintering performance of kiwifruit. The cut and wound of kiwifruit branch were not frozen and thawed, which reduced the alternate freeze-thaw injury,with the field incidence did not exceed 2.18%, and the prevention effect was not less than 84.5%. The field control effect was better when Cu (OH) 2 was added to the composite polymer. The incidence and prevention effect of kiwifruit sprayed with calcium based composite polymer adding Cu (OH) 2once were 1.34% and 90.5%, respectively, while incidence and prevention effect of kiwifruit sprayed with calcium based composite polymer adding Cu (OH)2 twice were 0.96% and 93.1%, respectively. The net photosynthetic rate, stomatal conductance, transpiration rate and total chlorophyll content of the susceptible kiwifruit plants after spraying calcium based composite polymer adding Cu (OH)2 for 3 months were 48.1%, 57.3%, 24.8% and 69.9% higher than those after spraying for 1 month, respectively. The intercellular CO2 concentration was reduced by 16.0%. When there was white bacterial pus, calcium based composite polymer adding Cu (OH)2 could be sprayed for treatment, with the cure rate not less than 87.5%.
