| 摘 要： | 以高感列当的食用向日葵品种“SH363”为试验材料,采用随机区组试验,研究不同播期、磷肥施用量和化学除草剂对向日葵列当寄生的影响.结果 表明:随着播期推迟,列当寄生程度呈现先升高后降低的趋势,6月14日和6月21日播种,向日葵列当寄生数量明显减少,适时晚播可以减轻向日葵列当的危害;磷肥施用量为337.5 kg/hm2时...

| Abstract: | Taking edible sunflower variety"SH363"with high sensitivity to Orobanche as the experimental material,the effects of different sowing date,application amount of phosphate fertilizer and chemical herbicide on parasitism of sunflower broomrape were studied by random block test.The results showed that,with the delay of sowing date,the parasitic degree of Orobanche increased first and then decreased;the number of parasitoids decreased significantly when sowing on June 14 and June 21;timely and late sowing could reduce the harm of Orobanche;when the application of P fertilizer was 337.5 kg/hm2,the number of parasitism was the least in comparison with other treatments;different doses of 48%Butralin,48%Trifluralin and 72%Dual gold could inhibit the parasitism of Orobanche,and the best effect was72%Dual gold(5400 mL/hm2),which had a good application prospect in reducing the parasitism of Orobanche. |
