摘要
杂草丛生是大面积种植甘蔗的严重威胁,在印度热带地区,为了促进机械化,种植甘蔗越来越受欢迎。通过连续两年的田间试验,评估了采用顺序施用和罐式混合施用除草剂(topramezone、tembotrione和halo磺隆甲基)和手工除草等多种杂草管理方法对甘蔗植物植物区系多样性、杂草控制效率和产量的影响。杂草密度最低,杂草生物量、除草效率最高和杂草控制指数观察三个手除草30,种植后60 - 90天(DAP)是与早期萌发后应用赛克津1250 g公顷种植−1在10天后(DAP)紧随其后(神奇动物)后出现的应用topramezone 29.4 +莠去津625 g公顷−1或halosulfuron甲基67.5 +赛克津525 g公顷−1或tembotrione 120 +莠去津625 g公顷−1 65 DAP fb手120 DAP除草。上述处理甘蔗产量最高,且显著优于不除草对照。净收益和效益:成本比也最高,出苗后早期施用metrizin 1250 g ha - 1, 10 DAP fb,出苗后施用topamezone 29.4 +阿特拉津625 g ha - 1或halo磺隆甲基67.5 + metrizin 525 g ha - 1或tembotrione 120 +阿特拉津625 g ha - 1, 65 DAP fb, 120 DAP手动除草。在测试剂量下,Topramezone、tembotrione和halo磺隆甲基对甘蔗品种Co 86032没有任何植物毒性,而Co 86032是热带印度的主要品种。甘蔗种植者可以在单手除草的同时轮作使用这些除草剂,以实现高效和经济的杂草管理。
Management of Diverse Weed Flora in Widely Spaced Sugarcane Plant Crop in Tropical India Through Sequential and Tank Mix Application of Herbicides
Weed infestation is a serious menace in widely spaced sugarcane, which is gaining popularity in tropical India to facilitate mechanization. Field trials were conducted for two consecutive years to assess the effect of various weed management approaches employing sequential and tank mix application of herbicides (topramezone, tembotrione and halosulfuron methyl) and hand weeding on diverse weed flora, weed control efficiency and yield of sugarcane plant crop. Lowest weed density, weed biomass, highest weed control efficiency and weed control index were observed for three hand weeding at 30, 60 and 90 days after planting (DAP) which was on par with early post-emergence application of metribuzin 1250 g ha−1 at 10 days after planting (DAP) followed by (fb) post emergence application of topramezone 29.4 + atrazine 625 g ha−1 or halosulfuron methyl 67.5 + metribuzin 525 g ha−1 or tembotrione 120 + atrazine 625 g ha−1 at 65 DAP fb hand weeding at 120 DAP. Highest cane yield was obtained with aforementioned treatments and they were significantly superior to unweeded control. The net returns and benefit: cost ratio was also highest with early post-emergence application of metribuzin 1250 g ha−1 at 10 DAP fb post emergence application of topramezone 29.4 + atrazine 625 g ha−1 or halosulfuron methyl 67.5 + metribuzin 525 g ha−1 or tembotrione 120 + atrazine 625 g ha−1 at 65 DAP fb hand weeding at 120 DAP. Topramezone, tembotrione and halosulfuron methyl at the tested dose did not record any phytotoxicity to sugarcane variety Co 86032, which is the ruling variety in tropical India. Sugarcane growers can use these herbicides in rotation along with one hand weeding for efficient and economic weed management.
期刊介绍:
The journal Sugar Tech is planned with every aim and objectives to provide a high-profile and updated research publications, comments and reviews on the most innovative, original and rigorous development in agriculture technologies for better crop improvement and production of sugar crops (sugarcane, sugar beet, sweet sorghum, Stevia, palm sugar, etc), sugar processing, bioethanol production, bioenergy, value addition and by-products. Inter-disciplinary studies of fundamental problems on the subjects are also given high priority. Thus, in addition to its full length and short papers on original research, the journal also covers regular feature articles, reviews, comments, scientific correspondence, etc.
