冀东平原设施辣椒水肥一体化技术应用效果研究

水肥一体化滴灌技术是提高设施蔬菜水分利用率的有效途径之一。通过设置2个不同施肥量处理,对滴灌施肥与畦灌冲肥作了比较。试验结果表明:设施辣椒采用水肥一体化滴灌技术具有较好的节水节肥效果,能够提高辣椒产量,改善辣椒品质,同时提高水分利用率。水肥一体化滴灌技术可节肥2 265 kg/hm2,节肥率40.3%;节水5 670 m3/hm2,节水率60.0%;增产6 435 kg/hm2,增产率达7.2%,为今后水肥一体化滴灌技术在设施辣椒上的推广应用提供一定的理论基础和技术支持。

Application and Research on Technology of Drip Irrigation and Fertilization Integration Adopted to Facilities Chilies on Jidong Plain

The technology of drip irrigation and fertilization integration is one of effective ways to improve the water utilization efficiency of facilities vegetables.Two different fertilizer processing was set up to compare the drip fertigation and flooding fertilization.The results showed that newly adopted technique of drip irrigation and fertilization integration had a good effect on saving water and fertilizer,ensuring the high yield,improving the quality of chilies and meanwhile increasing water-saving efficie...
