摘要

除草剂的频繁使用给人类和动物带来了生态和健康问题。此外,不明智的使用也使一些杂草对除草剂产生了抗性。因此,计划在2019- 2020年拉比期间,在7/3-L Ahmad Pur Sial区Jhang垦殖研究站对小麦进行实地调查,评估多种方法的杂草抑制效果。试验处理包括两个小麦品种(Ujala 2016和Faisalabad 2008)和7种杂草控制方法,即手动除草、有机覆盖、桉树提取物、楝树提取物、氯地那福、溴硝唑+ MCPA和氯地那福+溴硝唑+ MCPA包括控制。试验结果表明,手除草、氯地那福+溴硝腈+ MCPA配施和覆盖显著降低了杂草密度、鲜重和干重。然而,在土壤表面覆盖有机地膜对作物的生长和产量属性影响较大,因此产量最大。

Exploring different weeds management practices in wheat
Frequent utilization of herbicides has caused ecological and health complications for human beings as well as for animals. Moreover, its unwise application also developed resistance in some weed species against the herbicides. Therefore, a field investigation was planned to assess the effect of multi-approached weed suppression in wheat at Reclamation Research Station, 7/3-L Ahmad Pur Sial District Jhang during Rabi 2019-20. Experimental treatment was comprised of two wheat cultivars i.e. Ujala 2016 and Faisalabad 2008 and seven weeds control approaches i.e. hand weeding, organic mulching, eucalyptus extract, neem extract, clodinafop, bromoxynil + MCPA and clodinafop + bromoxynil + MCPA including control. Results of the experiment showed that hand weedings, combined application of clodinafop + bromoxynil + MCPA and mulching significantly reduced the weeds density, fresh and dry weight of weeds. However, covering the soil surface with the organic mulch may have a great impact on the growth and yield-contributing attributes, hence produced maximum grain yield.
