【摘要】 利用全周期胶园落叶期间作矮生四季豆,分析其生长和产量相关因子表现,为胶园落叶期蔬菜间作提供依据.结果表明,全周期胶园林下间作矮生四季豆的平均产量为5 593.24 kg·hm^-2,间作位置距离橡胶树愈近,产量愈低,产量高低顺序为M10>CK>W7>E7>E4>W4.间作区M10的产量为8 247.56 kg·hm^-2,与裸地对照(8 046.64 kg·hm^-2)无显著差异.间作区矮生四季豆植株生物量表现为W4最低,CK最高,M10、W7、E7和E4之间无显著差异.矮生四季豆植株叶面积和叶片SPAD的表现与产量表现一致,M10植株测定值均高于间作区其它位置.相关性分析结果表明,全周期胶园林下间作矮生四季豆的新鲜豆荚产量与抽蔓期SPAD值,苗期和结荚期的叶面积,植株生物量呈极显著的正相关.因此,全周期胶园落叶期间作矮生四季豆可通过提高叶片SPAD值,叶面积和植株生物量的途径来提高其豆荚产量.更多还原

【Abstract】 To improve the economic benefit of rubber plantation, intercropping system was introduced by planting dwarf yam bean in paired row. Leaf area, SPAD value and yield performance of dwarf yam bean were recorded to evaluate the system.The results showed that the average yield of dwarf yam bean intercropped rubber tree was 5 593.24 kg·hm^-2. M10 produced the highest pod yield(8 247.56 kg·hm^-2), followed by CK(8 046.64 kg·hm^-2), W7, E7, E4 and W4. CK produced the highest biomass while W4 produced the lowest. There were no significant difference among M10, W7, E7, and E4 on biomass. The leaf area and leaf SPAD of M10 were significantly higher than the control and other positions of the intercropping area. Pod yield was significantly positively correlated with plant biomass, vine SPAD value, leaf area at seedling stage and pod setting stage. Therefore, dwarf green bean is a likely candidate as an intercrop in rubber plantation with paired row planting system over wintering period. It is possible to increase the pod yield of intercropped dwarf yam bean by increasing leaf SPAD value, leaf area and plant biomass.更多还原
