[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 tillage methods on the yield and quality of wheat. [Method] Three kinds of tillage positioning experiments were conducted on wheat for two consecutive years from 2007 to 2008 and from 2008 to 2009. The three tillage methods are CK: shallow tillage (less tillage) operation mode, tillage depth 12 cm, tillage harrow 1 tillage 1 tillage tillage 20 cm tillage after tillage shallow tillage Less plowing): farming depth 12 ~ 14 cm. [Result] The effects of different tillage methods on wheat yield differed in different years. Appropriate deep tillage was conducive to reducing soil bulk density, improving soil physical properties, improving soil water storage and soil conservation characteristics and increasing wheat emergence rate and drought resistance. For the special drought period of early prophase, deep plowing of 20 cm is a key measure to achieve high yield of wheat. [Conclusion] The suitable tillage method for the stubble soil in Huaibei was found, which provided theoretical and practical basis for high yield and good quality of medium gluten wheat under the condition of mechanical sowing.
