以“津优303”黄瓜为试材,研究了补光对冬春茬温室黄瓜植株长势及产量品质的影响。结果表明:补光条件下黄瓜植株株高、茎粗、单瓜重均有所提高,每667m2产量较对照提高12.5%,净增产值8.4%,并明显提高了黄瓜的品质;尤其遇到连续阴天时,补光栽培表现出较强抗病增产能力。 The effects of supplemental light on cucumber plant growth and yield and quality in winter and spring greenhouse were studied using “Jinyou 303” cucumber as test material. The results showed that the plant height, stem diameter and single melon weight of cucumber increased under the condition of light supplementation. The yield per 667m2 was 12.5% ​​higher than that of the control and the net yield was 8.4%, and the cucumber quality was obviously improved. Especially, Cloudy days, fill light cultivation showed a strong disease-resistant and yield-producing ability.
