摘要:

探究硅肥对裸燕麦抗倒伏性能及籽粒产量的影响。采用随机区组设计,以抗倒伏品种白燕2号和倒伏敏感品种张莜9号为材料,于2024-2025年在内蒙古自治区乌兰察布市进行大田试验,设置5个硅肥处理,分别为0(CK),30(Si30),60(Si60),90(Si90),120 kg/hm2(Si120),测定分析不同硅肥处理对裸燕麦倒伏率、籽粒产量、茎秆强度和物质成分的影响。结果表明,硅肥极显著影响裸燕麦倒伏率,在Si60处理,白燕2号、张莜9号倒伏率与CK相比2 a间分别平均降低37.53,33.20百分点。2 a间,白燕2号在Si90处理籽粒产量最高,与CK相比平均提高19.06%;张莜9号在Si60处理籽粒产量最高,与CK相比平均提高28.09%。硅肥可改善茎基部第2节形态,与CK相比,分别平均降低裸燕麦茎基部第2节长19.82%,增加茎基部第2节粗18.17%,增加茎基部第2节壁厚41.77%。硅肥可增强裸燕麦茎秆机械强度,与CK相比,裸燕麦茎秆抗折力、茎秆穿刺强度、茎秆压碎强度分别平均增强27.78%,24.39%,16.33%。硅肥极显著影响裸燕麦茎基部第2节纤维素、硅含量,与CK相比,分别平均提高裸燕麦茎基部第2节纤维素含量、硅含量3.63%,11.32%。上述结果表明,针对抗倒伏裸燕麦品种施用硅肥90 kg/hm2可以保证籽粒产量最高且其抗倒伏性能不受影响;倒伏敏感品种施用硅肥60 kg/hm2抗倒伏性能、籽粒产量最高。

Abstract:

To investigate the effects of silicon fertilizer on lodging resistance and grain yield of naked oats,a randomized block design was adopted.Using the lodging-resistant variety Baiyan 2 and the lodging-susceptible variety Zhangyou 9 as materials,a field experiment was conducted in Ulanqab City,Inner Mongolia Autonomous Region,from 2024 to 2025.Five silicon fertilizer treatments were applied:0(CK),30(Si30),60(Si60),90(Si90),and 120 kg/ha(Si120).Measurements and analyses were performed to evaluate the effects of different silicon fertilizer treatments on lodging rate,grain yield,stem strength,and stem material composition of naked oats.The results showed that silicon fertilizer had a highly significant effect on the lodging rate of naked oats,compared with CK,the lodging rates of Baiyan 2 and Zhangyou 9 under the Si60 treatment were reduced by an average of 37.53 and 33.20 percentage points.Over the two-year period,the grain yield of Baiyan 2 peaked under the Si90 treatment,showing an average increase of 19.06% compared to CK;the grain yield of Zhangyou 9 peaked under the Si60 treatment,showing an average increase of 28.09% compared to CK.Silicon fertilizer improved the morphology of the second basal internode.Compared with CK,it significantly reduced the second internode length of naked oats by 19.82%;increased the second internode diameter of naked oats by 18.17%;and increased the second internode wall thickness of naked oats by 41.77%.Silicon fertilizer significantly enhanced the mechanical strength of naked oat stems,compared with CK,the stem breaking resistance,stem puncture strength,and stem crushing strength of naked oats increased significantly by 27.78%,24.39%,and 16.33%.Silicon fertilizer exerted a highly significant effect on the cellulose and silicon content in the second basal internode of naked oats.Compared with CK,it increased the cellulose content and silicon content in the second basal internode by 3.63% and 11.32%.The above results indicate that for lodging-resistant naked oat varieties,applying silicon fertilizer at 90 kg/ha ensures the highest grain yield while maintaining lodging resistance,and for lodging-sensitive varieties,applying silicon fertilizer at 60 kg/ha achieves the highest levels of both lodging resistance and grain yield.

Key words: Naked oats, Silicon fertilizer, Lodging resistance, Grain yield, Lodging rate
