摘要: 以太行山山前平原冬小麦为研究对象,在中国科学院栾城农业生态试验站,用筒栽模拟试验,研究了土壤表层和深层不同施肥供水组合对冬小麦根系分布、地上部生理特性及产量的影响。结果表明:与传统表层施肥+表层供水(CK)相比,①整层施肥+整层供水组合处理(T3)和整层施肥+表层供水组合处理(T1)的土壤上层(0~90 cm)根系生物量都没有显著变化,深层(90~10 cm)根系生物量分别增加了97.3%,7.0%,产量分别增加了46.0%,27.0%,生长后期,冬小麦旗叶净光合速率(Pn)、蒸腾速率(Tr)和水分利用效率(WUE)显著提高;②表层施肥+整层供水组合处理(T2)的土壤上层(0~90 cm)根系生物量减少了18.8%,深层(90~10 cm)没有显著变化,旗叶Pn、Tr、WUE及产量没有显著差异。

Abstract: Pot experiment was conducted at Luancheng Agro-Eco-Experimental station,Chinese Academy of Sciences(CAS),to study the effects of fertilization and water supply to different layers of soil on physiological traits,root distribution and yield of winter wheat in the piedmont of Taihang Mountain.The results showed that,compared with traditional fertilization applied to top soil layer and irrigation in surface soil(CK),the treatments with fertilization and water applied to the whole soil profile(T3)and fertilizing to the whole soil profile and water applied to the top soil layer(T1),root biomass of winter wheat in top soil layers(0-90 cm)had no significant difference,but root biomass in deep soil layers(90-150 cm)significantly increased by 97.3 % and 57.0 %,respectively.For treatment with fertilization applied to top soil layer and water applied to the whole soil profile(T2),compared with CK,root biomass in top soil layers(0-90cm)decreased by 18.8 %,whereas root biomass in deep soil layers(90-150 cm)was similar.Photosynthesis(Pn),transpiration(Tr)and water use efficiency(WUE)of flag leaf and grain yield of winter wheat for T2 had no significant difference with CK.But Pn,Tr,WUE of flag leaf of winter wheat for T3 and T1,at the later growing stage,were improved significantly.Grain yield of T3 and T1 substantially increased by 46.0 % and 27.0 % compared with CK,respectively.
