文档介绍：‘金煌’芒果疏果效应研究
摘要以11年‘金煌’芒果树为试验材料,通过人工疏果处理,研究‘金煌’芒疏果处理对单株产量和果实品质的影响。结果表明:结果母枝疏留果3个处理产量最高;不同处理平均单果重大果与小果均无显著差异;结果母枝疏留果1个处理,大果结果数量最多;大果品质优于小果。综合而言,在生产实践上,粗壮的结果母枝留果2个,较瘦弱枝留果1个最为合适。

Abstract The fruit of ‘Jinhuang’mango tree at the age of 11 years old were thinned artificially to observe the effect of thinning on yield and quality of the mango fruit. The results showed that the treatment with 3 fruits on each fruit branch yielded the highest. There were no significant differences in average single fruit weight of big and small fruit in all different treatments. The treatment with 1 fruit on each branch produced the largest number of big fruit. The big fruit had better quality than the smaller one. In summary, it is better to thin the fruit to keep 2 fruits on each sturdy fruit branch and 1 fruit on each weak fruit branch in practice.

作物?济产量和果实品质的形成依赖于其源库互作关系[1-2],调节合适的源库比例是作物高产栽培管理的重要任务之一。在源库关系的研究中,减源疏库及环剥是最常用的研究手段[3]。然而,可能是因为芒果树干易伤流以及叶片大小差异较大,不便于相关研究的开展,芒果源库关系方面的研究报道较少。近年来,海南芒果反季节栽培为把花期尽可能提前,过早采取控制树体营养生长的措施[4],忽视了果树树冠的培养,导致果树营养亏缺、树
