چکیده انگلیسی
The implementation of rotational tillage with straw mulching during a fallow period seems to be an effective management strategy to help store water for spring-sown crop. A site-specific field study was conducted according to rainfall conditions to determine the effect of rotational tillage on soil water regime, water use efficiency and grain yield in semi-arid region on the loess plateau of China. Six tillage practices were tested: NT/ST rotation (no-tillage was applied in the first year and rotated with sub-soiling in the second year), ST/CT rotation (sub-soiling was applied in the first year and rotated with conventional tillage in the second year), CT/NT rotation (conventional tillage was applied in the first year and rotated with no-tillage in the second year), NT (no-tillage was applied every year), ST (sub-soiling was applied every year), CT(conventional tillage was applied every year). The results showed that the rotational tillage increase average SWS (soil water at sowing) by 5.2â¯mm in dry years, 0.8â¯mm in normal years, and 13.2â¯mm in humid years when compared to CT. Soil water depletion was consistent with rainfall totals, and the lowest depletion value recorded in the NT/ST and followed by NT treatment. The grain yield was positively related with rainfall, and average grain yields for three rainfall conditions were ranked as NT/STâ¯>â¯CT/NTâ¯>â¯ST/CTâ¯>â¯STâ¯>â¯NTâ¯=â¯CT, while the soil water use efficiency (WUE) was ranked in the order of NT/ST,â>CT/NTâ¯>â¯ST, ST/CTâ¯>â¯NTâ¯>â¯CT. Grain yields of rotational tillage NT/ST, ST/CT and CT/NT are higher than the yield of NT by 6.5%-12.0%, higher than the yield of ST by 1.7%-7.0%, and 7.6%-13.2% higher than CT, respectively. Hence, rotational tillage could improve soil water storage, thus significantly increasing crop grain yield and water use efficiency. The method could have important applications in semi-arid areas.
