| 中文摘要: |
| 对灌溉定额为1 750、1 970、2 190、2 380 m3/hm2的矮化密植红枣滴灌试验研究表明：红枣果实膨大中后期土壤积盐明显，且主要集中在0～30 cm范围内，1 750 m3/hm2灌溉定额在红枣生育期使土壤积盐，2 380 m3/hm2灌溉定额洗盐效果明显；红枣生育期需水有两个峰值阶段，第一峰值阶段为初果期，第二峰值阶段为果实膨大中后期～成熟初期，且第二峰值大于第一峰值；红枣叶片日净光合速率有两个峰值，分别为中午13∶00和下午18∶30左右，且第一个峰值比第二个峰值大；2 190 m3/hm2的灌溉定额红枣产量最高。 |

| Field drip irrigation for dwarfing culture condensed planting red jujube experiment with 1 750, 1 970, 2 190 and 2 380 m3/hm2 irrigation quotas indicated that soil salt content accumulated significantly at mid and late fruit expanding stage and mainly in 0～30 cm soil vertical profile, 1 750 m3/hm2 irrigation quota caused soil salt accumulation for but other treatments leached soil salt; Red jujube had two ET peak values during growth period, with the first at initial fruit stage and the second at late fruit expa
nding to early mature stage; Photosynthesis rate had two peak values at 13∶00 PM and 18∶30 PM; The irrigation quota of 2 190 m3/hm2 were optimizational for red jujube yield. |
