不同模式配置对青贮用米豆复合体产量及玉米抗倒伏性能的影响研究
Study on the Effects of Different Configuration Modes on Yield of Forage Maize-Soybean Complex and Lodging Resistance of Maize
摘要
Abstract
To explore the influence of mode configuration on yield and lodging resistance of forage maize-soybean complex.Using forage maize variety'Jinling 10'and soybean variety'Zhonghuang 38'as the test variety,monoculture of maize as control(CK),three planting modes of ratio of forage maize to soybean was 2∶2(2+2),2∶3(2+3),4∶4(4+4).The agronomic traits of maize,the rind penetration strength,transverse breaking strength and yield of the 3rd,4th and 5th stems were measured at the milk stage.The results showed that the plant height of 4+4 was significantly lower than that of other treatments,and the ear position height coefficient of 4+4 was higher than that of 2+2 and 2+3,but the difference was not significant with CK.The rind penetration strength with the 3rd,4th and 5th in 4+4 mode were sig-nificantly higher than those of other treatments,while it was weakest performance in 2+2 mode.There was no significant difference in fresh yield between and dry weight 2+2 mode and 4+4 mode,both of which were significantly higher than that of CK.The dry weight of 2+2 and 4+4 modes was significantly higher than that of CK.Explanations on the ratio of forage maize to soybean was 4∶4(4+4)mode had higher yield and stronger lodging resistance in population.关键词
