以6个设施黄瓜主栽品种为试材,通过遮光处理,对植物的营养生长和生殖生长进行了研究。结果表明:津优30号产量最高,植株根冠比值和C/N比值较高,植株生长健壮;津优2号和津绿3号产量略低于津优30号,根冠比值和C/N比值适中;绿宁3号产量居中,根冠比值和C/N比值较低,营养生长旺盛;北极星和寒月产量最低,根冠比值适中,但C/N比值较低,植株以营养生长为主。综合比较得出:津优30号耐弱光性最好,津优2号和津绿3号耐弱光性较好,绿宁3号耐弱光性居中,寒月和北极星耐弱光性最差。
The main cucumber cultivars in six facilities were used as materials to study the vegetative and reproductive growth of plants. The results showed that the yield of Jinyou 30 was the highest, the ratio of plant root to shoot and the ratio of C / N were higher, and the plant grew robustly. The yield of Jinyou 2 and Jinlu 3 was slightly lower than that of Jinyou 30, the root / shoot ratio and C / N The ratio of root / shoot was moderate, but the ratio of root / shoot was moderate, but the ratio of C / N was lower, and the plant was mainly vegetative growth . The results showed that Jinyou 30 was the best tolerant to weak light, Jinyou 2 and Jinlu 3 were better tolerant to weaker light, and Ninging 3 was weaker than weak light, while Hanyue and Polaris were the least resistant to weak light .
