摘要
2005～2006年,在玉米丝黑穗病发生较为严重的山西省寿阳县,开展了以覆盖农膜为主,结合抗病品种和杀菌剂处理对玉米丝黑穗病控制效果以及玉米生长和产量影响的初步研究。结果显示,2005年和2006年,覆膜使玉米丝黑穗病的平均发病率分别从15.5%和8.9%降低到6.3%和6.5%,防治效果分别达59.4%和27.0%;使玉米产量分别提高746.2kg/hm2和1 410.0kg/hm2。选种抗丝黑穗病品种能显著降低丝黑穗病的发病率。晋单34号在2005年和2006年较宽诚1号和张玉1号丝黑穗病的发病率分别从17.3%和9.5%降低到4.5%和6.0%。本研究所选用的杀菌剂15%三唑酮、CAM和黑虫双全均未显著降低丝黑穗病的发病率。
Preliminary field trials were conducted to evaluate control effects of plastic film mulching,resistant corn varieties and fungicides on maize head smut disease in dry and semi-dry land conditions,maize growth and maize yield in 2005 and 2006 in Shouyang,Shanxi Province.The results showed that the incidence of maize head smut disease was decreased from 15.5% to 6.3% in 2005,and from 8.9% to 6.5% in 2006,by mulching plastic film.The control efficacy reached 59.4% and 27.0%,and the maize yield was increased by 746.2 kg/hm2 and 1410.0 kg/hm2,respectively.The incidence of maize head smut was decreased significantly by cultivating resistant corn varieties.Head smut Incidence of Jindan-34 was decreased from 17.3% to 4.5% and from 9.5% to 6.0%,respectively in the 2 years compared with Kuancheng-1 and Zhangyu-1.15% triadimefon,CAM and Tebuconazole used in this study could not significantly decrease the incidence of maize head smut.
