Abstract: [Objective] In order to explore the conservation tillage measures of jujube production in arid regions and promote the red jujube industry efficient,green,sustainable development in Southern Xinjiang.[Method]The soil water content from 0-100 cm soil layers in jujube orchard was evaluated and the yield of jujube and water use efficiency were analyzed by setting different conservation tillage methods.[Result] (1) The average soil water content with the treatment of tillage straw mulching (TS) reached 16.55 ;,which was 4.93;,1.97; and 7.34; higher than those of rotary tillage straw mulching (RS),no-till straw mulching (NS) and no-till bare land (NB) respectively.(2) In the whole growth period,soil water content of 0 to 100 soil profiles showed an overall increasing trend after the initial decrease.Tillage straw mulching (TS) obviously improved the soil water content of 60-100 cm soil profiles.(3) The yield and water use efficiency of the straw mulching (TS) were the highest,which were 10,500 kg/hm2 and 21.67 kg/hm2,respectively,compared with RS,NS,NB processing production,they were increased by 1,650 kg/hm2,3,000 kg/hm2,3,150 kg/hm2,and water use efficiency was increased by 4.33 kg/(mm · hm2),7.94 kg/(mm · hm2) and 8.07 kg/(mm · hm2).[Conclusion] A preliminary exploration of protection tillage straw mulching cultivation measures is more conducive to the implementation of jujube in extreme arid area.

摘要： [目的]研究适合干旱地区枣园生产的保护性耕作措施,促进南疆红枣产业高效、绿色、可持续发展.[方法]设置不同的保护性耕作措施,对枣园0～100 cm土层土壤含水量,分析红枣的产量以及水分利用效率.[结果](1)翻耕秸秆覆盖(TS)处理的平均土壤含水量达到16.55;,比旋耕秸秆覆盖(RS)、免耕秸秆覆盖(NS)、免耕裸地(NB)处理分别高了4.93;、1.97;、7.34;.(2)在枣树萌芽期、开花期、坐果期、成熟期,0～100 cm土层剖面的土壤含水量总体呈现“减少-增加-减少”的变化趋势,其中翻耕秸秆覆盖能有效提高60～100 cm土层的土壤含水量.(3)翻耕秸秆覆盖(TS)处理的红枣产量和水分利用效率最高,分别为10 500kg/hm2和21.67 kg/(mm·hm2),分别比RS、NS、NB处理产量增加了1 650、3 000和3 150 kg/hm2,水分利用效率增加了4.33、7.94和、8.07 kg/(mm· hm2).[结论]翻耕秸秆覆盖的保护性耕作措施,更有利于在极端干旱地区的枣园实施.
