| In experimental demonstration areas in Mengcha of Mizhi County in Shaanxi Province, against the situa
tion of the growing tensions in short water resources and low rainwater use efficiency， the experiments were conducted to study dynamic soil moisture, temperature and jujube growth under different conserving ways by located test in mountain areas of noethem Shaanxi. The result indicated that the straw and film mulching adjusted soil temperature, and the am-plitude on the temperature difference between straw mulching and CK was -5.5℃~0.25℃, while that between film mulching and CK was 1.32℃~5.17℃. Different soil moisture conserving treatments had higher water efest than CK. B12 (the use of water retaining agent is 120 g/ plant)，J2 (the use of straw is 2 kg/m2) and D (Film mulching) were higher in the process of changes in soil water content with time, while the average soil evaporation was lower than CK by
29.2%，23. 6% and 26. 4%, and the soil moisture was higher than CK by 22%, 25% and 13.5%. They could pro
mote jujube growth and increse jujube yield, and J2 was higher than CK by 37.3% and B12 by 32. 8%. Because the film mulching resulted in higher temperature in friut setting period, the yield was lower. B12, J2 and D increased mois ture conservation, and B12 and J2 also increased jujube yield. |
