中文摘要:
      旨在探讨耕作方式对山西旱塬区土壤水分、高粱产量及水分利用效率的影响,为旱作高粱高产栽培提供理论依据。采用田间试验,设置传统耕作、免耕、秋旋耕、秋深松、秋深耕+旋耕和春深耕+旋耕6 种耕作模式,研究不同处理对土壤水分、高粱产量及水分利用效率的影响。随着生育期的推进,播前土壤蓄水量和耗水量均以秋深耕+旋耕模式最高。与传统耕作和免耕模式相比,秋深耕+旋耕模式显著提高高粱产量,增产幅度分别47%和36.7%;显著提高水分利用效率,增加幅度分别达36.8%和25.5%;显著增加千粒重,增加幅度分别达16.5%和14.0%;显著增加枝梗数,增加幅度分别达22.2%和28.2%;显著增长高粱穗长,增长幅度分别达19.0%和21.2%。秋深耕+旋耕模式是本试验条件下的最优耕作模式,可作为山西旱塬区高粱生产适宜的耕作模式。
英文摘要:
      The study is to explore the effects of tillage methods on soil moisture, sorghum yield and water use efficiency in arid area of Shanxi Province, and provide reference for high-yield cultivation of dry sorghum. A field experiment was conducted, and six tillage modes were set up, including traditional tillage, no-tillage, autumn rotary tillage, autumn deep loosening, autumn deep tillage +rotary tillage and spring deep tillage + rotary tillage. With the advance of the growth period, soil water storage content and water consumption content before sowing was the highest under autumn deep tillage +rotary tillage. Compared with the traditional tillage and no- tillage mode, the mode of autumn deep tillage + rotary tillage significantly increased the yield of sorghum, and the yield increased by 47% and 36.7%, respectively, the water use efficiency was significantly increased by 36.8% and 25.5%, respectively, the 1000-grain weight was obviously increased with a rate of 16.5% and 14.0%, respectively, the number of branches was increased with a rate of 22.2% and 28.2%, respectively, and the spike length of sorghum was improved by a rate of 19.0% and 21.2%, respectively. The autumn deep tillage +rotary tillage mode is the best tillage mode under the experimental condition, and it could be used as a suitable tillage mode for sorghum production in dryland plateau of Shanxi Province.
