| 摘 要： | 研究了地膜覆盖棉田和露地棉田杂草的发生规律及化学防除措施。结果表明：不同栽培方式的杂草种类差异不大,地膜覆盖棉田杂草主要发生在5月初-5月上中旬,露地棉田杂草发生高峰期分别在5月20日左右、6月15日和7月中旬左右,地膜覆盖能抑制棉田杂草的发生和生长。地膜覆盖棉田的杂草防除以土壤处理为主,露地棉田采用土壤处理和茎叶处理相结合的方法防除杂草。

| Abstract: | The occurrence regularity and chemical control measures of weeds in film mulching field and open field of cotton were studied.The results showed that there had little difference in weed species with the two cultivation modes.The peak of weeds occurred from the beginning to the early and middle May in film mulching field,and that occurred on May 20,June 15 and middle ten days of July in open field.The film mulching could suppress the weeds germination and growth.The weeds were controlled in film mulching fie... |
