Effects of Hanging Different Materials on the Back Wall of Sunlight Greenhouse on Growth Characteristics and Quality of Gherkins ( Carica papaya )
摘要
Abstract
[ Objective ] In order to study the effects of hanging different materials on the back wall on growth characteristics and quality of gherkins, and provide a reference for its high yield and good quality cultivation. [ Method] This experiment designed two treatments of hanging black film and reflective screen on the black wall in the greenhouse, and took blank wall as control. Two treatments and control were arranged randomly with 3 repeated- [Result] At different growth stages, plant height, stem diameter at bottom, chlorophyll content, leaves'dynamic state of hanging reflective screen and black film treatments were better than those of control t but their overall difference was not significant. Plant height of hanging black film treatment was very significantly higher than that of hanging reflective screen treatment and control, but there was no significant difference between hanging reflective screen and control. No matter which area in the greenhouse, single melon weight of hanging reflective screen treatment was always significantly higher than that of hanging black film treatment and control, and hanging reflective screen and black film increased vertical and lateral diameter of fruits. After hanging reflective screen and black film, soluble solids content; total sugar content, total acid content and vitamin C content of gherkins fruit increased, especially total sugar content and vitamin C content. Thereinto, total sugar content of hanging black film was very significantly higher than that of hanging reflective screen, and hanging reflective screen was very significantly higher than that of control. Vitamin C content of hanging black film treatment was very significantly higher than that of hanging reflective screen treatment and control, but there was no significant difference between hanging reflective screen and control. [ Conclusion ] Hanging reflective screen and black film has no significant effects on growth indices of gherkins, but has significant influences on its quality. Hanging black film increases indoor temperature, reflective screen increases indoor light, so the fruit quality in the area is better than the blank wall, so it provides a reference for improving quality of gherkins.关键词
