烟草轻简高效栽培技术研究 ——Ⅳ.M型宽垄双行种植模式对土壤理化性状的影响

Study on Simplified and Labor Saving Cultivation of Tobacco——Ⅳ. Effects of M-regional crop rotation on soil physical and chemical properties

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。

Abstract: 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.
