    摘要:

    通過小區(qū)試驗，研究了粉碎,、氨化秸稈以及與無機土壤改良劑（硫酸鈣）混合配施措施對土壤水分及作物產(chǎn)量的影響,。結(jié)果表明,，氨化秸稈利于提高土壤對降水的保蓄能力，顯著增加0~100 cm土層土壤蓄水量,。在夏玉米-冬小麥輪作中,，氨化秸稈提高土壤蓄水能力主要反映在夏玉米苗期和冬小麥抽穗期。粉碎秸稈氨化與硫酸鈣處理的夏玉米,、冬小麥水分利用效率分別較粉碎秸稈覆蓋提高了4.97%,、30.32%，效果顯著。氨化秸稈施入土壤的措施較未氨化秸稈覆蓋還田的措施夏玉米,、冬小麥產(chǎn)量分別提高4.56%~10.00%和6.65%~11.12%,。

    Abstract:

    Field plot experiment was carried out to investigate the effects of the powdered, ammoniated straw and/or blending with inorganic soil amendment (calcium sulfate) on soil moisture and crop yields in summer maize and winter wheat rotation systems. The results showed that the ammoniated straw could improve soil storage ability for precipitation, compared with CK1, and significantly increase the soil water storage (0~100 cm). The ammoniated straw improving soil water storage ability was observed mainly in seedling stage of summer maize and heading stage of winter wheat in the crops rotation spectively. Treatment, the powdered and ammoniated straw blended with calcium sulfate, compared with CK1, could significantly increase ecnomic yield of summer maize, winter wheat by 4.97% and 30.32%, respectively. The ammoniated straw returned to soil,compared with the unammoniated straw mulched soil, could distinctly increase yields of summer maize, winter wheat by 4.56%~10.00% and 6.65%~11.12%. 
