摘要:

摘要：【目的】探究3种颜色地膜覆盖对四川盆地秋季黄瓜的影响。【方法】设置4个处理，透明膜（T1）、黑色膜（T2）和银灰色膜（T3）及不覆盖（CK），分析了3种颜色薄膜对四川盆地秋季土壤温度、黄瓜生长及产量的影响。【结果】在秋季弱光条件下，与CK相比，地膜覆盖均增加了土壤不同深度的根区温度，在5、10 cm和15 cm的深度下，T1、T2处理和T3处理的平均根区温度分别比露地高0.8～0.9℃，0.5～0.6℃和0.2～0.6℃。与CK相比，T1、T2处理和T3处理的黄瓜株高分别增加了6.9%、8.7%和15.3%，单株果实数分别增加了20.6%、20.6%和8.8%，小区总产量分别增加了19.25%、7.18%和16.24%。说明3种颜色地膜覆盖均可以增加土壤温度、促进黄瓜生长，进而提高黄瓜产量，但3种地膜间均无显著差异。【结论】3种不同颜色地膜覆盖黄瓜的产量之间无显著差异，但均能提高四川盆地弱光区秋季黄瓜的产量。

Abstract:

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.
