| Abstract: |
| 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. |
