摘要
在自然基本条件(降雨量、温度、肥力、原生植被等)相对一致的同一试验点,采用不同播种期和先锋种建植人工草地,应用生物统计Tukey方法,对新建人工草场的杂害草控制进行抽样调查.结果表明:在新建人工草地时,采用“播种前整地+人工除草+雨季结束前20 d播种+速生先锋种”的方法与其他方法相比,对于控制新建人工草场的杂害草效果更佳.
Investigation was made to study weed control in grasslands newly established in different seeding times with different pioneer species. The collected datas were analyzed by Tukey statistics. The results showed that among eight different trials,the best weed control was found in the scheme with ＂soil treatment prior seeding＋ hand-removal weeding＋ seeding on the day 20 prior ending of raining season＋ fast growing pioneer species＂.
