AA级绿色食品花生田除草技术研究

A study on weeding technology of AA level green food peanut field

根据AA级绿色食品特点和农时操作的具体要求,1999—2002年对AA级绿色食品花生田除草技术进行了研究,明确了夏播花生田利用覆盖物和不同地膜防除杂草的效果均较好;春播花生田覆盖黑色地膜和无色增温地膜,除草和增产效果显著。花生收获前15d人工揭除地膜,不影响花生产量并可有效减少残膜污染。

Basing on AA level geen food peanut's feature and the demanding of cultivation management, wee- ding technology of AA level green food peanut were studied from 1999 to 2002. The results showed that the weeding effects of covering with different covers and plastic films without pesticide were well in summer peanut field. The effects of covering black film and increasing temperature film on weeding and increasing yield were marked in spring peanut field. The film pollution could be reduce by artificial collected.
