大豆新品种皖豆24的试验示范与推广

Trial Demonstration and Extension of the New Soybean Variety Wandou 24

[目的]为大豆新品种皖豆24的推广栽培提供理论依据。[方法]以大豆新品种皖豆24为试验对象，将多项实用大豆栽培技术组装配套应用于皖豆24的试验示范与推广中。[结果]在2006年的生产示范试验中，怀远龙亢农场的皖豆24的平均产量为2904．0kg/hm^2，比对照品种徐豆9号增产6．5％，最高单产达3507．0kg/hm^2；风台东风湖农场的皖豆24的平均产量为2737．5kg/hm^2，比对照品种徐豆9号增产7．7％，最高单产达3699．0kg/hm^2。皖豆24的适播期为6月上中旬。苗期每公顷用50％抗蚜威可湿性粉剂90～120g或10％吡虫啉可湿性粉剂150～300g兑水450～750k喷雾防治蚜虫。鼓粒期每公顷用20％氰戊菊酯乳油300—600ml喷雾防治豆荚螟和大豆食心虫。[结论]在安徽省皖北地区推广种植皖豆24能切实促进农民增产增收。

[Objective] The research aimed to supply theoretical foundation for the extensive cultivation of the new soybean variety Wandou 24. [Method] With the new soybean variety Wandou 24 as tested object,many practical cultivation technologies of soybean were assembled,rrkatched and applied in the trial demonstration and extension of Wandou 24. [ Result ] In the productive demonstration experiment perfomaed in 2006, the mean yield of Wandou 24 in Longkang farm of Huaiyuan was 2 904.0 kg/hm^2 and increased by 6.5% in comparison with the control variety Xudou 9, its highest single yield was up to 3 507.0 kg/hm^2; the mean yield of Wandou 24 in Dongfenghu farm of Fengtai was 2 737.5 kg/hm^2 and increased by 7.7% in comparison with the control variety Xudou 9,its highest single yield was up to 3 699.0 kg/hm^2 .The suitable sowing date of Wandou 24 was in early and middle Jun.The aphids oc- curred in seedling stage could be controlled by spraying 90 - 120 g 50% pirimicarb WP or 150 - 300 g 10% imidaclopfid WP diluted with 450 - 750 kg water per hectare. The Etiella zinckenella and Leguminivora glycinvoralla occurred in seed- filling stage could be controlled by spraying 300- 600 ml 20% fenvalerate EC per hectare. [ Conclusion] The extension and planting of Wandon 24 in the north of Anhui Province could increase the soybean yield and the income of farmers practically.
