【摘要】 针对目前林农复合经营中应用的宽窄行配置模式,研究其对水稻产量及其品质的影响。结果表明:杨稻间作前3年对稻穗生物量、产量、谷草比、蛋白质、直链淀粉含量的影响不显著,对千粒重、单穗重、穗长等指标有显著影响。间作5年将使得水稻的千粒重有所降低,蛋白质、直链淀粉含量则有所增加。不同配置模式对水稻产量的影响与杨树的树龄有很大的关系,为减少遮荫对树冠的影响,应当多采用宽行配置模式。更多还原

【Abstract】 Effects of poplar-crop agroforestry patterns on rice yield and quality were analyzed.The results indicated that the poplar-crop agroforestry patterns had no significant effects on the rice ear biomass,yield,ratio of yield to biomass,protein content and amylose content within three years,while the patterns affected the 1000 grains weight,one ear weight and ear length significantly.The 1000 grains weight was reduced,but protein content and amylose content were improved,in the 5th year of poplar-crop management.The effects on yield among different patterns were related to the age of the poplar plantations,and the wider-narrow pattern should be applied in order to reduce the influence of tree’s over-shading.更多还原
