| 摘 要： | 目的]探讨中草药靓果安对库尔勒香梨叶片叶绿素含量、果实糖度及腐烂病防治效果的影响。方法]采用全树喷施不同杀菌剂的方法,测定叶片叶绿素含量、果实糖度以及田间调查腐烂病防效。结果]不同方位叶片中的叶绿素SPAD值差异不显著;2.6%靓果安AS、10%苯醚甲环唑WG、80%乙蒜油OL(除绿树神医AS外)叶绿素SPAD值均较CK增加,且差异显著,但不同处理间叶绿素含量差异不显著。单一杀菌剂与对照的果实糖度无显著差异,最高增加0.586%,而靓果安+杀菌剂的2个处理与CK存在极显著差异,最低增加0.897%。腐烂病的防治效果为40.90%~62.68%。结论]靓果安可有效增加叶片中叶绿素和果实总糖含量,提高树体对腐烂病防病抗病能力,改善果实品质,其中以靓果安+杀菌剂混用效果最佳,适用于梨园大面积的应用。

Effects of Liangguoan AS on Chlorophyll Content,Fruit Sugar Content and Rot Disease control Effect of Korla Fragrant Pear |
| |
| Abstract: | Objective] To study effects of Liangguoan AS which is an Chinese herbal fungicide on chlorophyll content,fruit sugar content and rot disease control effect of Korla fragrant pear.Method]After spraying the whole tree, leaf chlorophyll content and fruit sugar content were determinated and control effect of rot disease was surveyed.Result] There was no significant difference of chlorophyll SPAD value in different direction of leaf.Except peroxyacetic acid AS, the chlorophyll SPAD value of 2.6% Liang Guo-an AS, 10% Difenoconazole WG, 80%Ethylicinr OL were both higher than CK significantly.Fruit sugar content had no significant difference between the test of single fungicide and CK, the highest value added was 0.586%, but Liangguoan composed of the other fungicide had extreme significant difference compared with CK,the lowest value added was 0.897%.The control effect of valsa canker between 40.90% and 62.68%.Conclusion] 2.6%Liangguoan can increase chlorophyll content of leaf,total sugar content, improve the quality of fruit, enhance the ability of fighting canker effectively, which had more effective if composed of the other fungicide.It can be widely used in pear production. |
