以甜椒品种“布兰妮”为试材,研究了三层甜椒专用棚膜与3种五层共挤棚膜对温室内光环境,甜椒长势、光合特性、产量和果实品质等的影响。结果表明:五层共挤多功能膜在透光率方面高于三层甜椒专用膜,但三层甜椒专用膜在植株长势、产量以及果实品质方面均高于五层共挤多功能膜。说明三层甜椒专用膜更适合北方温室甜椒栽培。 With the sweet pepper variety “Britney” as the test material, the effects of three layers of sweet pepper special greenhouse film and three kinds of five layers coextruded film on the light environment, the growth of sweet pepper, photosynthetic characteristics, yield and fruit quality And so on. The results showed that the five-layer co-extruded multi-functional film was higher than the three-layer peppers special film in the light transmittance, but the three-layer peppers special film was higher than the five-layer co-extruded multifunctional film in plant growth, yield and fruit quality . Three layers of pepper special film is more suitable for greenhouse cultivation of green peppers in the North.
