| 摘 要： | 研究在全周期胶园宽行间作豆薯和大豆的产量、品质和土壤速效养分的影响。结果表明,与单作相比,间作大豆产量显著降低40%(p0.05),间作豆薯产量略低但差异不显著(p0.05)。总体上,单作和间作处理豆薯和大豆不同位置的可溶性糖、淀粉、粗蛋白和粗脂肪的含量没有显著差异(p0.05),但间作提高了间作带中间区域豆薯的粗脂肪含量。单作豆薯和大豆平均土壤铵态氮、硝态氮均显著高于间作处理的不同位置(p0.05);单作豆薯和大豆土壤速效钾含量高于间作处理且显著高于单作小区两侧(p0.05);而单作豆薯和大豆土壤速效磷则低于间作处理,其中单作豆薯显著低于间作豆薯小区中间区域(p0.05)。综上所述,豆薯比大豆更适合间作于全周期胶园,间作对作物的品质总体上没有影响,但对降低土壤无机氮含量较明显。

| Abstract: | The yield, quality and soil rapidly available nutrient of yam bean and soybean intercropped in the wide row of rubber plantation with paired row planting system were investigated in current study. Results showed that, compared to monocultural treatment, the yield of intercropped soybean was significantly reduced by 40%(p<0.05). The yield of intercropped yam bean was lower than the monocultural treatment but there was no significant difference(p<0.05). Totally, the concentration of soluble sugar, starch, crude protein and oil in different sites in intercropped yam beam and soybean didn''t differ to those in monocultural treatments(p>0.05). But intercropping increased oil content of yam beam in the central area of the intercropped treatment. Average soil ammonium nitrogen and nitrate nitrogen in the two monocultral treatments were significantly higher than those in different sites in the intercropped treatments(p<0.05). The content of rapidly available potassium in the two monocultural treatments were higher than in the intercropped treatments, and all significantly higher in outboard sides of the intercropping plots(p>0.05). Contrarily, the content of rapidly available phosphorus in the two monocultural treatment were lower than in the intercropped treatments. Only the content of rapidly available phosphorus in the middle area of intercropping yam beam was significantly higher than that in the monocultural yam beam(p<0.05). Conclusively, yam bean was more suitable than soybean to be intercropped in the rubber plantation. There was no evident effect of intercropping on crop quality. But soil inorganic nitrogen was decreased by intercropping. |
