摘  要:
对灌溉定额为1 7501、9702、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。

摘  要:
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 expanding 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.
