| 中文摘要: |
| 于2002~2004年在青海省乐都县的典型干旱山区进行温室辣椒集水节灌试验。试验结果表明,要使山旱地温棚产量大幅度提高,补充水量在根系范围内田间最大持水量的60%~80%之间经济效益最佳;同时灌溉方式以人为控制根系双侧大小沟交替进行灌溉具有显著的增产效果;补充水分关键时期应在初花后10 d开始的生殖生长集中期内。 |
| 英文摘要: |
| The experiment was conducted in Ledou County,Qinghai Province to study the effects of water-saving irrigation with catchment water on capsicum in greenhouse on mountainous dryland.The results indicated: when the soil moisture in the range of roots was kept within 60%~80% of field capacity by supplementary irrigation,the yields and benefits of capsicum in greenhouse were the best;the optimal irrigation style was the irrigation through large and small ditches alternatively;the key time of supplementary irrigation was the procreation stage after 10 d of flowering. |
