摘 要:为了降低劳动强度,减少烟草种植的连作障碍问题,采用田间试验方法,研究了M型宽垄双行区域轮作种植模式对土壤理化性状的影响。结果表明,M型宽垄双行种植能提高土壤含水量22.60%,提高移栽初期土壤温度,团棵期高温时土壤温度比单垄单行降低10.6-2.7℃,可以避免高温障碍;M型宽垄双行增强了土壤酶活性,提高土壤养分含量,对改良土壤能发挥重要作用。Reducing labor intensity and solving continuous cropping obstacles were the purpose of this study.Application effects of M-regional crop rotation on soil physical and chemical properties were studied in tobacco production.The results showed that M-ridge increased soil moisture content by 22.60%.The soil temperature in transplanting period also increased while the temperature decreased by 10.6-2.7 ℃ at resettling growth stage,which was useful to avoid high-temperature obstacle.M-wide double ridge also improved soil enzyme activities and soil nutrient content,which played an important role in soil improvement.
