不同转红光棚膜对黄瓜生长、产量及品质的影响

Effects of Different Red Light Greenhouse Films on Growth, Yield and Quality of Cucumber

为了验证新型棚膜在生产应用中的效果,本试验以黄瓜品种‘津优35号’为试材,研究加入红色母粒的涂覆型消雾无滴转红光棚膜的透光性及对黄瓜植株生长、产量和品质的影响。结果表明:不同种类转光剂对日光温室光环境、黄瓜生长发育均有显著影响。与对照及其他棚膜相比,添加转光剂KMN-2试验膜的透过光谱中红橙光比例显著提高,能够明显促进黄瓜植株生长发育,提高产量,明显增加果实可溶性糖、维生素C (Vc)、游离氨基酸和可溶性蛋白含量。综上,红色膜中加入适宜转光剂能够促进黄瓜植株生长,进而增加产量,改善品质。

In order to verify the effect of the new shed film in production and application, this experiment used the cucumber variety’Jinyou No.35’ as the test material to study the light transmittance of the coated anti-fog-free red shed film with red masterbatch and effects on the growth, yield and quality of cucumber plants. The results showed that different kinds of light-transfer agents had significant effects on the light environment of cucumber and the growth and development of cucumber. Compared with the control and other shed films, the ratio of red orange light in the transmission spectrum of the added light conversion agent KMN-2 test film was significantly improved, which could significantly promote the growth and development of cucumber plants, increase the yield, and significantly increase the soluble sugar and vitamin of Vc, free amino acid and soluble protein content. In summary, the addition of a suitable light conversion agent to the red film can promote the growth of cucumber plants, thereby increasing yield and improving quality.
