摘要
为提高山旱地日光节能温室辣椒生产过程中对水分和肥料的利用效率,采用膜下滴灌施肥、露地滴灌施肥技术,以地面灌溉施肥为对照,考察了辣椒产量、经济效益、水分及肥料的利用率、辣椒的生物学性状、抗病性以及不同灌溉方式对山旱地日光节能温室中土壤含水量、土壤温度、湿度等各项指标的影响。结果表明:滴灌施肥较地面灌溉施肥增产16.6%~28.9%,增收每667 m2500.7~959.2元,节水13.5%~28.1%,节肥28.4%,单株结果数增加8.9~11.8个,发病率降低11.6%~16.6%,土壤含水量提高1.2%~3.49%,地温提高3.2℃以上,湿度控制在50%~70%。滴灌施肥较地面灌溉施肥具有增产增收节本增效的功能。
To improve utilization efficiency of water and fertilizer by pepper planted in energy saving greenhouse in dry mountain area,drip irrigation with fertilizer in under-film and open conditions were tested,and conventional irrigation with fertilizer was used as a check.The items investigated included pepper yield,economic efficiency,utilization efficiency of water and fertilizer,pepper biological character,disease resistance,soil water content.soil temperature and air moisture.The results were:yield increased ...
