摘要
在位于典型大陆性极端干旱气候类型的农一师十三团试验田研究了同一种耕作方式下,秸秆覆盖处理(TS)、不覆盖处理(TB)和地膜覆盖处理(TF)对土壤水分及红枣产量的影响。结果表明:(1)同一种耕作模式下,秸秆覆盖处理的土壤水分含量显著的高于不覆盖处理和地膜覆盖处理,该种覆盖方式下土壤水分利用效率较高,具有较好的保墒作用;(2)秸秆覆盖处理的枣吊数目显著的高于不覆盖处理和地面覆盖处理,而不覆盖处理和地面覆盖处理间差异不显著,表明秸秆覆盖有利于提高枣吊数;(3)秸秆覆盖处理的枣果产量显著高于翻耕不覆盖处理和地面覆盖处理,且该处理下的果品品质也优于其他两个处理。
In the typical continental extreme arid climate area of 13th Regiment in First Agricultural Division, a field experiment was conducted with different mulching of straw mulch （＇IS） , no cover treatment （TB） and plastic film mulching treatment （TF） under ro- tary tillage, the effects on soil moisture and yield of red dates were studied. The results show that ： （ 1 ） With the same tillage method, the soil water content in straw mulching treatment was significantly higher than those of both the no cover and plastic film mulching treatments, the straw mulching treatment was higher in preserving soil moisture and water use efficiency compared with other treat- ments. （2） The jujube number of straw mulching treatment was significantly higher than those of no covering and plastic film mulching treatments, and no significant difference was observed between the no covering and plastic film mulching treatments, this indicated that the straw mulching could improve the jujube number. （3） The straw mulching treatment had higher jujube fruit yield and higher fruit quality when compared with those of no covering and plastic film mulehing treatments.
