| Abstract: Cucumber is one of the main varieties of cultivation in Sichuan basin. The annual average solar radiation is less than 1500 MJ/m2, which lower than cucumber's requirement for light, therefore, the growth and development of cucumbers may be inhibited when grown under low light conditions in fall. Many studies have shown that plastic film mulching can improve the light energy utilization efficiency of plants, and increased yield of them. 【Objective】In order to explore the effect of three color film mulching on cucumber growth and yield in fall in the Sichuan Basin. 【Method】In this study, 4 treatments were established comparing the use of three color plastic films including transparent film (T1), black film (T2), and silver-black film (T3), to Not mulched (CK). 【Result】In low light conditions in fall, the film mulching increased the root zone temperature at different depths of the soil compared with the bare soil. The average root zone temperature of T1, T2 and T3 increased by 0.8～0.9℃, 0.5～0.6℃ and 0.2～0.6℃, respectively, at the soil depth of 5 cm, 10 cm and 15 cm. Compared with the CK, the plant height of cucumber of T1, T2 and T3 increased by 6.9%, 8.7% and 15.3%, respectively. The number of fruits per plant was increased by 20.6%, 20.6% and 8.8%, respectively. The plot total yield of cucumber was increased by 19.25%, 7.18% and 16.24% respectively. Therefore, the three color plastic film mulching can increase soil temperature and promote cucumber growth, thereby increasing cucumber yield. However, there is no significant difference among the three color plastic film. 【Conclusion】The film mulching is useful to improve the yield of cucumber, but there was no difference between the three tested color plastic film mulches during fall in a poor light region. |
