摘　　要：为进一步验证不同浓度的红糖及生物发酵菌液对早春马铃薯抗冻、抗病性及产量的影响,设置4个不同浓度的处理,以喷施清水作空白对照,比较不同浓度的红糖与生物发酵菌液对马铃薯抗冻、抗病及产量的影响。试验结果表明,叶面喷施红糖及生物发酵菌液可显著提高马铃薯的抗冻及抗病性;以叶面喷施红糖90倍及生物发酵菌液60倍混合液的抗冻、抗病、增产等综合效果最好。In order to further verify the effects of different concentrations of brown sugar and bio-fermented bacterial liquid on frost resistance,disease resistance and yield of early spring potato,four treatments with different concentrations were set up to compare the effects of different concentrations of brown sugar and bio-fermented bacterial liquid on frost resistance,disease resistance and yield of potato with spraying water as the blank control.The results showed that foliar spraying of brown sugar and bio-fermented bacterial liquid could significantly improve the frost resistance and disease resistance of potato.The comprehensive effect of frost resistance,disease resistance and yield increase was the best when the mixture of brown sugar 90 times and bio-fermented bacterial liquid 60 times was sprayed on the leaves.
