摘要
选择长江中下游地区主栽的水稻品种12个,通过盆钵试验对比各品种水稻对杂草的抑制效果,评价各品种对杂草的抑草能力,分析水稻生物量与水稻抑草能力间的关系。结果显示水稻对杂草的抑制效果总体上与水稻干物质积累量呈正相关,并初步筛选出在生产上具备推广潜力的抑草水稻品种天协6号和两优华6。
12 common rice varieties were selected to compare the weed resistance of each rice variety by potted plant experiment, and relationship between dry weight of rice and weeds resistance capability was analysed. The results showed that weeds resistance capability and rice dry matter accumulation was positively correlated. Tianxie 6 and Liangyouhua 6 were selected in the actual production.
