摘要
开展温室越冬茬番茄水肥一体化栽培模式与传统灌溉栽培模式对比试验。结果表明,水肥一体化栽培模式最高可节约灌溉水33.17%,节约用工26.22%,同时可减轻病虫害的发生;在水肥一体化栽培模式中减少传统习惯施肥用量1/3的情况下,产量增加6.77%,在减半的情况下产量呈现下降趋势。
A comparative experiment was carried out between the integrated cultivation mode of water and fertilizer and the traditional irrigation cultivation mode.The results showed that the integrated cultivation mode of water and fertilizer could save 33.17%of irrigation water and 26.22%of labor,and reduce the occurrence of diseases and pests at the same time.In the integrated cultivation mode of water and fertilizer,the yield increased by 6.77%in the case of reducing traditional customary fertilization amount by 1/3,the yield showed a downward trend under the halving.
