摘要
以‘农青2号’罗汉果为试验材料,在露地进行棚架与篱架密植栽培试验,统计单位面积产果数和各等级果实率,分析果实甜苷Ⅴ、总糖和V–C含量的变化。结果表明:棚架栽培每1 hm2产果数较篱架栽培提高了10.8%,二者差异显著;2种架式特果率、大果率和中果率间的差异均无统计学意义;2种架式每1 hm2产果数随栽培密度的增大而明显增加,但特果率和大果率随栽培密度的增大总体呈下降趋势,架式、密度、架式与密度互作对中果率和外果率的影响无统计学意义,小果率随栽培密度的增大总体呈上升趋势;篱架栽培果实甜苷Ⅴ含量较棚架栽培提高了9.6%,2种架式间差异显著,但2种架式总糖、V–C含量间的差异均无统计学意义;2种架式甜苷Ⅴ、总糖和V–C含量随栽培密度的增大呈先上升后下降的趋势;棚架栽培在行株距2.0 m×2.0 m条件下能获得较好的鲜销品质,篱架在行株距1.5 m×2.5 m条件下的果实加工品质较好。
A kind of Siraitia grosvenorii, Nongqing NO.2, was planted at scaffolding and trellis close planting mode in open field, to investigate its fruit number, fruit rate of various grades, as well as to test the change of mogroside V, gross sugar and vitamin C in fruit at 1 hm^2 area. The results showed that the fruit number at scaffolding mode was increased by 10.8% compared with that of trellis close planting mode, but the differences among the rate of extra big size fruit, big size fruit and middle size fruit were no significance. The fruit number per hm2 at both planting mode was obviously increased with planting density, however, the rate of extra big size fruit and big size fruit were declined with the increase of planting density. There were no impact of trellis form, density and planting mode on the rate of middle size fruit and substandard fruit, while, the rate of small size fruit showed an increased trend with planting density. The content of mogroside V cultured at trellis close planting mode increased by 9.6% compared with that of cultured at scaffolding mode, however, there was no difference in content of V~ and total sugar between the two modes. The content of sweet glycosides V, total sugar and V-C increased firstly, and then decreased with planting density in both modes. Good marketing fresh quality could be acquired at scaffolding mode with the planting space at 2.0 m × 2.0 m, while good processing quality could be gotten at the planting space with 1.5 m × 2.5 m at trellis close planting mode.
