摘要: 通过爬地和立架2种栽培方式,研究其对2个哈密瓜品种叶片光合速率及果实产量、品质的影响。结果表明: 在植株伸蔓期,爬地栽培低节位叶片光合速率高于立架栽培,而高节位叶片光合速率立架栽培高于爬地栽培;2种栽培方式在不同生育期的叶片光合速率均存在显著差异。随着植株生长,叶片光合速率呈先升后降的趋势,爬地栽培叶片光合速率最大值出现在果实发育初期(授粉后7 d左右),而立架栽培叶片光合速率最大值发生在果实发育中期(授粉后20 d左右);在爬地栽培光合速率达峰值前,其值始终大于立架栽培,但之后立架栽培光合速率则显著高于爬地栽培;相比爬地栽培,立架栽培平均单果重增加163%~277%,果实中心可溶性固形物含量增加178%~309%。可见哈密瓜立架栽培比爬地栽培的产量和果实内在品质均有提高。

Abstract: The experiment on two kinds of cultivation methods was carried out to study the effect of cultivation methods on photosynthetic rate,fruit yield and quality of Cucumis melo var. saccharinus. The results showed that: during the vineextend stage,the photosynthetic rate of leaves located at the lower vine under frame culture was higher than that under groundclimb culture,while,photosynthetic rate of leaves located at the upper vine under frame culture was lower than that under groundclimb culture. Photosynthetic rate changed greatly among the various growth stages. With the growth of plant,photosynthetic rate increased firstly,and then decreased. The peak of photosynthetic rate of groundclimb cultured plant emerged on 7 days after pollination,while photosynthetic rate of frame cultured plant reached maximum on 20 days after pollination. The photosynthetic rate of groundclimb cultured plant was higher than that of frame cultured plant before 7 days after pollination. Afterwards,photosynthetic rate of frame cultured plant was higher than that of groundclimb cultured plant significantly. Compared with groundclimb cultured plant,average fruit weight and soluble solid content of framed cultured plant were increased by 163%-277% and 178%-309% respectively. The framed culture method can improve the yield and quality of Hami melon.
