摘要
用多菌灵15%+福美双15%可湿性粉剂配制1.00~10.00g/L10个不同浓度系列,对九重葛插穗进行3h浸泡处理后扦插试验。结果表明,各处理中最佳的插穗平均生根数、根长、根直径、叶片数、新枝数、新枝长分别为34.2片、25.28mm、1.16mm、39条、3.8条、141.6mm。最高成活率达到100%,所测生长指标与对照组的差异极显著(P〈0.01)。处理剂量在1.00~2.50g/L,插穗生根数、成活率、根长、根径、新叶数、新枝数和新枝长均与处理剂量的关系呈二次曲线模型(R^2〉0.94)。结果分析显示,最佳处理的理论剂量为1.82g/L。
The experiment in Cuttage of Bougainvillea spectabilis Willd was conducted with the treatment of 15 % Carbendazim + 15 % Thirarn WP with the different concentrations from 1.00 g/L to 10.00 g/L for 3 h.The results showed that the optimal evenness of ten treatments was roots of cutting, 34. 2; root length, 25.28 mm; root diameter, 1.16 mm; new leaf of every cutting, 39; new branch, 3.8; new branch length, 141.6 mm and the highest cuttage survival rotes were 100 %. The difference were significant between the treatment and control groups( P 〈 0.01). The relationship met the Quadratic model between rooting, survival rate, root length, root diameter, new leaf of every cutting, new branch, new branch length and dose-uslng during the treatment concentrations from 1.00 g/L to 2.50 g/L(R^2 〉 0.94).The analysis of test results indicated that the optimal treatment concentration for B. spectabilis Willd was 1.82 g/L.
