摘要: 为给大麦高产节水栽培技术提供理论依据,以‘甘啤4号’为供试材料,在大田条件下分析了全膜覆土穴播、垄作沟灌及平作条播栽培模式对大麦农田土壤温度、产量的影响。结果表明,出苗至拔节期土壤温度全膜穴播>垄作沟灌>平作条播,全膜穴播处理土壤温度显著高于平作条播。拔节后,土壤温度表现为垄作沟灌处理土壤温度均高于同层全膜覆土穴播和平作条播处理,大麦垄作沟灌栽培可以增加表层0 cm和5 cm处的土壤温度;全膜穴播栽培可以增加清晨5 cm以下土层土壤温度,并且降低土层5 cm以下温度变化。全膜穴播处理产量较平作条播和垄作沟灌分别高出10.9%和15.31%。

Abstract: In order to provide theoretical basis for water-saving production and high yield of barely, three cultivation management modes including over film-mulched soil cultivation, controlled traffic tillage with ridge irrigation and conventional drilling were conducted to investigate their dynamics change of soil temperature, yield of barely under field conditions. The results showed that from emergence to jointing stage, soil temperature was over film- mulched soil cultivation > controlled traffic tillage with ridge irrigation > conventional drilling, and soil temperature of over film-mulched soil cultivation was significantly higher than that of conventional drilling. After jointing stage, soil temperature of controlled traffic tillage with ridge irrigation was the highest in the different layers, and this mode could increase temperature at 0 cm and 5 cm of the soil. Over film-mulched soil cultivation could increase soil temperature of 5 cm below in the morning and reduce the temperature change of 5 cm below of the soil. Yield of over film-mulched soil cultivation increased by 10.9% and 15.31% compared with the other two cultivation modes.
