摘 要: | 为了评价玉米带耕沟播模式下机械培土对抗倒性状及产量和产量结构的影响。以生产常规模式不培土不化控为对照(T1ck),设生产常规模式不培土化控(T2)、带耕沟播模式不培土不化控(T3)、带耕沟播模式不培土化控(T4)、带耕沟播模式喇叭口期培土1次(T5)和带耕沟播模式抽雄期培土1次(T6),进行大田比较试验,结果表明:带耕沟播喇叭口期培土玉米穗位高度比对照降低16.49cm,茎秆田间抗拉弯强度比对照增加30.72%,室内横折强度比对照增加28.50 %,百粒重增加1.51g,穗粒数增加64.09粒,比对照增产20.09%。带耕沟播喇叭口期机械培土不仅提高玉米茎秆的抗倒能力,同时增加产量。

Hilling of Belt Tillage with Furrow Planting: Effects on Lodging Resistance and Yield of Maize |
| |
Abstract: | The aim is to evaluate the effect of mechanical hilling on the lodging resistance, yield and yield structure of maize under the belt tillage with furrow planting (BTFP).‘Zhengdan658’was used as the material, according to random block arrangement, 6 treatments were set up according to the combination of tillage methods (normal tillage and BTFP) with hilling and chemical control. The ear height, internode character, stem strength and yield performance of different treatments were analyzed. The results showed that compared with the control, the ear height with hilling of BTFP at bell-mouth stage decreased by 16.49 cm, the tensile bending strength increased by 30.72% , the intensity of cross breaks increased by 28.50% , the 100- grain weight increased by 1.51 g, the kernels per ear increased by 64.09 grains, and the yield increased by 20.09% . Therefore, the mechanical hilling of BTFB at bell-mouth stage could not only improve lodging resistance but also increase the yield of maize. |
