株行距配置对新冬59生长发育及抗倒伏能力的影响
Effects of plant and row spacing configurations on the growth and development and lodging resistance of Xindong 59
摘要
Abstract
To investigate the effects of plant and row spacing configurations on the growth,development and lodging resistance of the winter wheat variety Xindong 59,a field experiment was conducted using Xindong 59 as the test material.4 row spacing treatments were set:T1(7.5 cm×7.5 cm),T2(10.0 cm×10.0 cm),T3(12.5 cm×12.5 cm),and T4(15.0 cm×15.0 cm,conventional spacing).Morphological indices including plant height,internode length,and internode diameter were measured,and correlation analysis was performed among these indices.The results showed that wheat in the T2 treatment exhibited the maximum values plant height,length of the first basal internode,length from the second basal internode to the top of the spike,diameter of the first basal internode,diameter of the second basal internode,and gravity center height,which were 97.57 cm,5.37 cm,88.30 cm,4.04 mm,4.53 mm,and 45.47 cm,respectively,with significant differences compared with the T4 treatment(P<0.05).No significant difference in the filling degree of the second internode was observed among all treatments(P>0.05).T2 treatment exhibited the highest lodging resistance index of 22.77,and the difference was not statistically significant compared with the T4 treatment(P>0.05).Correlation analysis indicated that the lodging resistance index of wheat was significantly positively correlated with plant height and the length from the second basal internode to the top of the spike(P<0.01).In summary,the suitable plant and row spacing for Xindong 59 was 10.0 cm×10.0 cm,under which the population structure was optimized and the overall lodging resistance was improved.The results provide a reference for scientific planting and high-yielding cultivation of Xindong 59.关键词
