| 中文摘要: |
| 为了解玉米秸秆还田下耕作方式与增施有机肥对小麦茎秆抗倒特性的调节作用，在前期定位试验的基础上，于2014-2015和2015-2016小麦生长季，选用百农207为材料，分析玉米秸秆全量粉碎还田条件下，不同耕作方式（深耕、浅耕、免耕）与增施有机肥相结合后小麦茎秆主要物理特性、抗倒性及产量的变化。结果表明，增施有机肥后小麦灌浆中后期的茎秆重心高度降低，茎秆鲜重、基部第二节间的茎壁粗度及茎壁厚度增加，抗折力增强，倒伏指数降低，抗倒性提高。两个年度的数据显示，小麦茎秆抗倒性均以深耕+有机肥处理效果最好，浅耕+有机肥处理次之；同时，深耕+有机肥处理（2014-2015）与浅耕+有机肥处理（2015-2016）产量较高。 |

| Lodging is one of the important constraints to high yield and stable production of wheat. This study investigated the effect of different tillage and application of organic fertilizer under corn straw returning into field on culm lodging resistance of wheat to provide a theoretical basis for high yield wheat production at the basis of pre-positioning test. Bainong 207 was used as material in 2014-2015 and 2015-2016.Six treatments,such as deep tillage(DT),shallow tillage(ST),no-tillage(NT),deep tillage and application of organic fertilizer(DTF),shallow tillage and application of organic fertilizer(STF),and no-tillage or application of organic fertilizer(NTF),were conducted to investigate the main physical morphological characteristics,lodging resistance characteristics of wheat culm and wheat yield. The results showed that application of organic fertilizer could increase the lodging resistance of wheat culm. The lodging resistance of wheat culm was different at different stages. The main reasons for the lodging resistance increase of wheat were that the application of organic fertilizer increased breaking resistance of internodes,decreased the gravity center height,and increased the fresh weight of stem,internode diameter and culm wall thickness of the second internode of the culm. Lodging resistance under the treatment of DTF was better than the others,followed by STF. At the same time,the yield was relatively high under DTF(2014-2015) and STF(2015-2016). |
