摘要
农牧交错区保护性耕作小麦发生杂草30余种,较传统耕作杂草发生密度增高31.8（~42.6%,频度增加13.3（~31.6%。2年生及多年生杂草发生程度已构成灾害。试验采用化学除草在苗期茎叶喷雾用2,4-D丁酯、二甲四氯、护麦、骠马,抑阔宁＋骠马、护麦＋阔莠克、2,4-D丁酯＋骠马除草剂配伍组合收效显著;机械除草用浅旋＋中耕除草收效显著;机械与化学相结合用浅旋＋化学除草收效显著。
There were about 30 species of weed in the protectively cultivated wheat field in transitional areas of farming and pasturing,and the weed density was 31.8%~42.6% higher,the frequency of weed was 13.3%~31.6% higher than the conventional areas,and the weed damage was severe.The weeding experiments were conducted by chemical weeding with 2,4-D butyl ester,MCPA,Humai,Piaoma,the effects of combinations of Yikuoning ＋ Piaoma,Humai ＋ Kuoxiuke and 2,4-D butyl ester ＋ Piaoma,sprayed on the stems and leaves in seedling stage were better;the effect of mechanical weeding by shallow rotation ＋ middle tillage weeding were better;the effect of the combination of mechanical and chemical weeding by shallow rotation ＋ chemical weeding and comprehensive weeding were all better.
