摘要

甜椒育苗期使用80目紗網保護可有效防止經由蚜蟲携帶傳播的病毒。田間蚜蟲數量在本試驗甜椒生長期以二月中旬逹高峰。銀色塑膠布對蚜蟲忌避效果在甜椒生長初期最佳，隨植株的發育其忌避效果隨之減弱。銀色塑膠布覆蓋處理區施用0.75%濃度的夏油乳劑及友村796乳劑對股病率分別降低43.5%及35.9%，無覆蓋處理區施用0.75%濃度的夏油乳劑及友村796乳劑對發病率分別降低43.6%及38.5%。銀色塑膠布覆蓋與油劑處理的交感效應無顯著的差異。銀色塑膠布的覆蓋及施用油劑對産量、植株鮮重、結果數均有顯著的效果。

Raising seedling stage of sweet pepper covered with 80 mesh nylon is effectively for prevention virus diseases which carry through aphid. In the field experiments, the amount of aphid reached maximum at mod February. It appears that in the early growth period of sweet pepper, the best. effectiveness of aphid, shading by reflective white plastic cloth. And the influence decreased due to the plant developed gradually. Spraying of 0.75% summer oil and orchex 796 oil reagents in the field condition could be prevented the virus infection to 43.5% and 35.9%, respectively under plastic cloth covered area. At the same time, it shows 43.6% and 38.5% individually on the area without plastic cloth (control). There is no significant interaction between cover of reflective white plastic cloth and oil reagents. on the other hand, apply of oil reagents and cover of white plastic cloth could be increased the growth yield and fruit setting.
