小麦-花生套作对花生光合色素、生长性状和产量的影响

Effects of the Peanut Relay-cropped Wheat on Photosynthetic Pigments,Growth Traits and Yield of Peanut

通过田间试验,以单作花生(MC)为对照,观测分析了麦田套作(RC)对花生光合色素、生长性状和产量的影响。结果表明:与单作花生相比,套作花生苗期和饱果期光合色素含量高,盛花期延迟,花期较长,日开花数少;主茎高、第一对侧枝长及侧枝数均比单作小或少,但结果枝数和果针数多于单作,荚果产量低于单作;根茎叶生物产量低,饱果数、百果数及百仁重小,秕果数多。

Effect of relay-cropped peanut with wheat（RC）on photosynthetic pigments,growth traits and yield of peanut were studied by comparing RC with mono-cropped peanut（MC） in the field.The main results were described as follow： Photosynthetic pigments contents of RC were higher at seedling and podding stage,full-bloom stage delayed,florescence was prolonged,flower number of each day was smaller.Main stem height,first pair of lateral branches length and lateral branch number were smaller and less,but fructified branches number and pod aciculas number were larger,pod yields were lower.Biology yields of roots,stems and leaves were lower,full pod number,One hundred pods weight and One hundred seeds weight were smaller,blighted pod number was larger than MC.
