不同产量水平下青稞倒伏相关因素研究
|
摘要
为探明影响青稞倒伏的相关生物学性状。采用大田生产对比法,根据地力水平、管理水平选择代表不同产量水平的10个地块,通过方差分析和相关性分析探讨不同产量水平青稞田的倒伏与株高、节间长度、整株鲜重、植株鲜重、植株干重、根鲜重、根干重的关系。方差分析结果表明倒伏青稞的株高、节1~4、生物量、产量等均表现优势,相关分析结果表明倒伏与节2~4显著相关,青稞每667m~2产量与各因素的相关均不显著。倒伏青稞的株高、节1~4、生物量、产量性状较未倒伏青稞高,青稞是否会发生倒伏与节2~4显著相关,青稞的每667m~2产量与青稞是否倒伏不相关。
This experiment adopted the field production correlation method. 10 plots that represented different levels of production were selected,according to the land level and management level. Using variance analysis and correlation analysis methods,the relationships between highland barley lodging and plant height,septate internodes,fresh weight of barley,fresh weight of over ground part and root system,dry weight of over ground part and root system were discussed. Variance analysis results showed that the plant height,internode 1-internode 4 fresh weight of barley,fresh weight of over ground part and root system,dry weight of over ground part and root system,production of falling highland barley were better than those unlodged. Correlation analysis results showed that lodging was significantly correlated with internode 2,internode 3 and internode 4. Correlation between yield and other factors was not significant.
