在盆景生长季节及休眠季节,56%磷化铝粉剂“8g/m3×24h”与“6g/m3×36h”两种处理的杀虫效果均较理想;生长季节试验的58种盆景中发现10种有明显药害,但常见的出口盆景品种基本无药害;休眠季节有药害品种占试验品种总数的16%。两种处理在两种季节的PH3浓度均维持在φ(PH3)=750×10-6以上。磷化铝片剂由于药害较大,不宜进行出口盆景熏蒸灭虫。
In the bonsai growth season and dormancy season, the insecticidal effects of 56% aluminum phosphide powder “8g / m3 × 24h” and “6g / m3 × 36h” were all ideal. Among the 58 bonsai growing season trials, 10 Species obvious phytotoxicity, but the common export bonsai varieties basically no phytotoxicity; dormancy season, medicinal species accounted for 16% of the total varieties tested. The PH3 concentrations of both treatments were maintained at φ (PH3) = 750 × 10-6 in both seasons. Aluminum phosphide tablets due to greater injury, should not be exported fumigation fumigation of bonsai pests.
