摘要
试验共设地面覆盖秸秆、覆盖地膜、覆盖秸秆+地膜以及对照四个处理,采用随机区组设计。研究了不同地面覆盖对日光温室黄瓜生产及水分利用效率的影响,以期为日光温室黄瓜生产筛选最佳覆盖模式,为发展节水型生态农业提供理论依据和技术支持。结果表明:①地面覆盖能有效促进植株与瓜条生长发育,提高正常瓜比例,其中以覆盖秸秆+地膜效果最好;②地面覆盖的黄瓜产量显著高于对照,覆盖秸秆+地膜在提高早期产量与总产量的效果最好,覆盖地膜在提高早期产量上优于覆盖秸秆,但后期产量远低于覆盖秸秆处理,总产量低于覆盖秸秆处理;③地面覆盖可有效改善瓜条品质,增加黄瓜的干物质含量、可溶性糖含量、维生素C含量、可溶性蛋白质含量及游离氨基酸总量,且以覆盖秸秆+地膜效果最好;④覆盖秸秆、覆盖地膜与覆盖秸秆+地膜的水分利用效率极显著高于对照,分别较对照提高74.2%、112.5%与102.3%,覆盖地膜与覆盖秸秆+地膜的水分利用效率显著高于覆盖秸秆处理。
Randomized plot design was used among soil surface mulching treatments, such as wheat straw mulching, plastic film mulching, wheat straw and plastic film mulching and no mulching in this experiment. The effects of soil surface mulching on cucumber production and water use efficiency were studied to choose a better mulching model and supplying theoretical basis and technique support for water-saving agriculture. The results showed that： ① Three soil surface mulching treatments significantly promoted cucumber growth and enhanced normal fruit ratio, furthermore, wheat straw and plastic film mulching made better effects than the other two treatments; ② The yields of all mulching treatments were much higher than that of control. Wheat straw and plastic film mulching gave the highest early yield and total yield. Plastic film mulching increased early yield higher, but much lower yield at late stage than that of wheat straw mulching, so that made total yield lower than wheat straw mulching;③ Soil surface mulching significantly increased the content of dry matter, soluble sugar, vitamin C, soluble protein and total dissociative amino acid, and improvement effects of wheat straw and plastic film mulching were much better than that of wheat straw mulching and plastic film mulching; ④ Water use efficiencies of soil surface mulching treatments were much higher than that of control, and were respectively 74.2%, 112. 5% and 102. 3% higher than control in order of wheat straw mulching, plastic film mulching and wheat straw and plastic film mulching. Moreover, the values of water use efficiency of plastic film mulching and wheat straw and plastic film mulching were significantly higher than that of wheat straw mulching.
