摘要
为缓解马铃薯生产过程中出现的前茬药害对其生长发育和产量的影响,选用5种缓解药剂对前茬有药害的土壤进行处理。结果表明:处理3(药害清+赤霉素920)和处理5(解毒灵+赤霉素920)有一定的缓解效果,马铃薯植株的生长性状与未喷施任何除草剂土壤的对照差异不明显,属正常生长发育,其产量也属正常,商品薯率达到80%以上,可在生产实践中推广应用。
To relieve the problem about the phytotoxicity from previous crop seriously affected the growth,development and yield of potato,five antidotes were chosen to treat the soil contained phytotoxicity from previous crop.The results showed that the treatment 3（Yaohaiqing and Gibberellin 920） and the treatment 5（Jieduling and Gibberellin 920） had some curing effects.Compared with the control soil which was not sprayed herbicide,the difference of growth traits of potato plants was not obvious.Its growth and development was normal,so was the yield.Its marketable tuber rate reached above 80 percent and it could be extended and applied in the production practice.
