处理后的生活污水对柠檬生长及果实的影响

Effects of Reclaimed Water on Growth of Lemon Tree and Its Fruit

利用处理后的生活污水灌溉农作物既能节约用水,又能有效缓解城市用水和农业用水的矛盾.以清洁河水为对照,探讨了灌溉不同量的处理后的生活污水对柠檬生长及果实的影响.结果表明:处理后的生活污水对柠檬树体生长和柠檬产量及品质的影响与对照无显著差异;但灌溉量多的树体生长快,主干和树冠生长迅速,产量较高,果实着色较差,可溶性固形物含量显著减少;果园杂草生长茂盛,生长量大.

Crop irrigation with treated sewage effluent not only conserves water,but also is an effective way to relieve the conflict between the greater requirment of urban water and the increasing consumption of agricultural water using.The reaction of lemon to irrigation of different amount of reclaimed water was evaluated by using Corolado river water as a control.The result showed:compared with the clean river water,the irrigation with reclaimed water had the same effect on growth of lemon tree and its fruit development;lemon trees irrigated with large more amount of water grew fast and gave a higher yield in spite of the poor color fruit,low juice soluble solids and increased weed cover accompanied by high irrigation rate,which were manageable.
