- 摘要:
- 以3%甲维氟铃脲乳油(A1)、20%毒死蜱微囊悬浮剂(A2)和10%阿维除虫脲乳油(A3)为供试药剂,分别采用方差分析和同异分析方法,对上述3种药剂3种剂量即500倍液(B1)、1 000倍液(B2)和1 500倍液(B3)和清水(CK)对李树桃蛀螟的防治效果(好果率)和综合效益(好果率、好果产量、收入和净增纯收益)进行了分析和评价,以期为李树桃蛀螟防治的科学、合理用药提供参考。结果表明:仅从防治效果、成本考虑,以A2B2(喷施20%毒死蜱微囊悬浮剂1 000倍液2次)为宜,好果率达到96.00%;从好果率、好果产量、收入和净增纯收益等综合效益考虑,则以A1B1(喷施3%甲维氟铃脲乳油500倍液2次)效果最好,4 个指标分别达到98.00%、17 640.0 kg?hm-2、70 560.0元?hm-2和6 675.0元?hm-2。
- Abstract:
- The pesticides 3% Jiawei fluoride bell urea cream (A1),20% Chlorpyrifos millirod suspending agent (A2) and 10% Avi deinsectization urea cream (A3) were used as the test fungicides.By using analysis of variance and similarity-difference analysis methods,the control effect (healthy fruit rate) and comprehensive benefits (healthy fruit rate,healthy fruit yield,income and net income) of the above three kinds of agents and three doses,namely 500 times liquid (B1),1 000 times liquid (B2),and 1 500 times liquid (B3) and water (CK) on Dichocrocis puncticralis Guenee for plum tree were analyzed and evaluatedin order to provide reference for the application of pesticides in the field.The results showed that if only considering the control effect and cost,A2B2 (spraying 20% chlorpyrifos millirod suspending agent 1 000 times liquid twice) would be advisable,the healthy fruit rate reached 96.00%;but if considering the comprehensive benefits such as healthy fruit rate,healthy fruit yield,income and net incomes,A1B1 (spraying 3% Jiawei fluoride bell urea 500 times liquid twice) would be better,its four indexes were 98.00%,17 640 kg?hm-2,70 560 RMB?hm-2and 6 675 RMB?hm-2 respectively.
