3.2试验区域的划分 将试验区按照下表划分为 20个试验小区, 每个试验小区 '的面积为 40m2, 每个试验 小区按标记组别分别施用上述表 4中所述的药剂。 试验区情况见表 5。 表 5
3.3施药当天天气状况
施药当日少云, 平均气温 29.9Ό , 相对湿度 72%, 无降水过程, 施药后 2-10天, 以多云天气为主, 其中 2天有降水过程, 总降雨量 46.9mm, 气温 29.8-31.1 °C, 相对湿 度 66-72%。 试验地为红壤土, pH5.8左右。
3.4施药方法

4、 药效计算方法
分别于药后 15天、 30天各调查一次杂草株数, 药后 30天加测杂草鲜重。药效计算 公式如下:
, β 对照区杂萆株数(或鲜重) 一处理区杂草株数 (或鲜重) 1 Λη 欢果 ( ) = ^~^^^¾¥杂草株数 (或鲜重) x 100
并用邓肯氏新复极差( DM T )法分析差异显著性。
5、 结果 每天对试验区内的杂草进行定点观察, 药后 4-5天有的杂草心叶开始失绿, 6-7天 停止生长, 之后开始萎蔫、 枯黄直至死亡, 施药后致杂草枯死为 7-20天。 药后 15天、 30天后杂草防除情况见下表 6-8。 下表 6-8中, 药剂 1表示 80%草甘膦胆碱水溶性粒剂 600克 /公顷, 药剂 2表示 80%草甘膦胆碱水溶性粒剂 1200克 /公顷, 药剂 3表示 80%草 甘膦胆碱水溶性粒剂 1800克 /公顷, 药剂 4表示 80%草甘膦胆碱水溶性粒剂 2000克 /公 顷, 药剂 5表示 74.7%草甘膦铵盐可溶性粒剂 2241克 /公顷。 表 6对杂草株数防除效果(%)—施药后 15天
表 8对杂草鲜重防除效果(%)—施药后 30天
用邓肯氏新复极差(DMRT )法进行统计分析防效的差异显著性。 从试验结果看, 本 发明 80%草甘膦胆碱水溶性粒剂对马唐、 牛筋草、 胜红蓟、 龙葵、 旱稗等杂草比较敏 感, 随着用药剂量的增加, 对杂草的防除效果提高。
对药后 30天的株数总防效进行分析可知, 低剂量与中剂量、 高剂量防效之间两两 比较差异极显著; 对药后 30天的鲜重总防效进行分析可知, 低剂量、 中剂量、 高剂量 防效之间两两比较差异极显著。
三、按照上述二中所述方法,对上述实施例 2-1至 2-11和 3-1至 3-10的制剂进行药效研 究, 有效成分用量均为 2000克 /公顷, 具体如下表 9: 表 9对杂草株数防除效果(%)—施药后 30天
从上述数据可以看出, 各个制剂按照有效成分 2000克 /公顷用量可以有效防除田间 各类杂草。 本发明通过助剂的选择, 所得的水溶性粒剂药物效果优异。
