- The average effect of spraying 30%DT WP in booting date on controlling rice false smut was 89.6%.The method is effective in controlling rice false smut. 应用30%25DT可湿性粉剂在水稻孕穗期喷雾防治稻曲病平均效果达89.;6%25,可作为防治稻曲病的有效措施。
- SAS results indicated false smut of rice analysis mainly influenced the yield of rice by percentage of diseased ears rate, next is the percentage of diseased spikes rate. 用SAS统计软件分析田间数据结果表明稻曲病影响水稻产量的主因素是病穗率,其次是病粒率,病穴率是次要因素。
- Fifteen sugarcane varieties could be divided into 6 groups on the basis of the distance more than 1.0.It resulted most ot tested sugarcane varieties had similar smut resistance. 在类间距离大于1.;0的条件下;可将15个品种聚为6类;进一步明确了各品种抗黑穗病性的相似程度;
- Percentage of diseased hill holerate is the secondary factor.The occurrence extent of false smut of rice mainly depended on the quantity of chlamydospore that over-wintered last year. 根据田块中的厚垣孢子含量推断,影响水稻稻曲病发病程度的主因素可能是上年的厚垣孢子在田间的越冬量。
