摘要
为了筛选出适合余姚地区种植的优良茭白品种,于2023年对7个茭白品种(系)的农艺性状、经济性状、熟期和抗病性等方面进行了比较试验,试验结果表明,从整个生育期来看,浙农7号锈病和胡麻斑病发病最轻,耐高温孕茭性好,其秋茭产茭时间最早(9月1日),分蘖性能优,有效苗最多,茭形好,秋茭每667 m^(2)产量和效益分别比对照品种本地八月茭高17.5%和24.6%,是综合性优良、产量高、效益好的一个新品(系),可以作为本地早熟品种种植。引进的几个品种(系)中,回山茭植株高大,出茭率高,产茭期与对照本地八月茭接近,抗病性中等,每667 m^(2)产量比对照本地八月茭高22.4%,667 m^(2)效益比对照本地八月茭高22.4%,适合在本地推广种植。
In order to select excellent varieties of Zizania latifolia suitable for planting in Yuyao area,we conducted comparative experiments on the agronomic traits,economic traits,maturity period,and disease resistance of seven Zizania latifolia varieties(lines)in 2023.The results showed that from the entire growth period,Zhenong 7 had the least incidence of rust and sesame spot disease,good heat resistance and good fertility,and the earliest production time of autumn Zizania latifolia(September 1st).It had excellent tillering performance,the most effective seedlings,and good shape.The 667 m^(2) yield and benefits of autumn Zizania latifolia were 17.5%and 24.6%higher than those of the control August Zizania latifolia,respectively.It is a new variety(line)with excellent comprehensiveness,high yield,and good benefits,and can be planted as a local early maturing variety.Among the several introduced varieties(strains),Huishan Zizania latifolia had tall plants,high yield rate,similar production period to the control August Zizania latifolia,and moderate disease resistance.The 667 m^(2) yield was 22.4%higher than that of the control August Zizania latifolia,and the 667 m^(2) benefit was 22.4%higher than that of the control August Zizania latifolia,making it suitable for local promotion and planting.
