经15年试验,比较了以宜昌橙6个不同选系作砧木,对哈姆林甜橙树体生长、果实产量及品质的影响。结果表明,树冠最高大的是以1号选系作砧者,最矮小的是以6号选系作砧者,其树冠体积分别为枳砧对照的31.8％和4.7％;单位树冠体积产量以6号选系为砧者最高,而单株产量和单位树冠投影面积产量则以1号选系为砧者最高;不同选系宜昌橙砧对哈姆林甜橙果实大小、果皮厚薄也有明显影响。认为宜昌橙1号选系为此较有希望的矮化砧木,6号选系宜作超密植栽培的砧木材料。
After 15 years of experiment, the effects of six different selection lines of Yichang orange on rootstock growth, fruit yield and quality were compared. The results showed that the crown with the highest crown was selected as rootstock by No.1, and the shortest was rootstock with No. 6 as the rootstock. The crown volume of crown was 31.8% and 4.7% of the control. No. 6 was the highest, and the output per plant and canopy crown was the highest among those with No. 1 selection. Different selection of Yichang orange anvil had a significant effect on the fruit size and peel thickness of Hamlin . Yichang orange No. 1 selection system for this more promising dwarfing rootstock, No. 6 election should be suitable for ultra-dense cultivation of rootstock material.
