摘要
[目的]研究不同耕作方式对小麦产量和品质的影响。[方法]2007～2008、2008～2009年连续2年对小麦进行3种耕作方式定位试验。3种耕作方式分别为CK:浅旋耕(少耕)作业模式,耕深12 cm,耕后耙;1耕(松耕)1耙:耕深20 cm,耕后旋耕;浅旋耕(少耕):耕深12～14 cm。[结果]不同耕作方式对小麦产量的影响在不同年份间有所差异;适当深耕,有利于降低土壤容重,改良土壤物理性状,改善土壤蓄水保墒特性,提高小麦出苗率及抗旱能力。对于前期持续干旱的特殊年份,深耕20 cm的耕作方式是实现小麦高产的一项关键措施。[结论]寻找到淮北旱茬土壤适宜的耕作方式,为机播条件下中筋小麦优质高产栽培提供理论及实践依据。
[Objective]The research aimed to study the effects of different farming methods on growth,yield and characters of wheat.[Method] The continuous 2 years location tests in 2007 - 2008 and 2008 - 2009 for 3 farming methods were made,CK（minimal tillage,tilling depth 12 cm,harrowing after tillage）,one tillage-one harrowing（tilling depth 20 cm,rotary tillage after tillage） and minimal tillage（tilling depth 12 - 14 cm）.[Result]The effects of different farming methods on wheat yield were difference in different years.The appropriate deeply tillage was favorable to reduce soil bulk density,improve soil physical properties,modify soil the properties of holding water and preserving soil moisture, develop wheat emergence rate and the seedling drought-resistant ability.The depth 20 cm was the key measures of achieving wheat high yield in special drought year with continual dry in earlier stage.[Conclusion]The study finds the suitalbe drought soil farming methods in Huaibei Area,can provide the theoretical and practical basis for high quality and high yield cultivated of medium - strength wheat under mechanical sowing condition.
