以长富2号为指示品种,采用连续多年定位试验,研究了集雨保墒措施对黄土旱塬苹果产量与品质的影响。通过对比分析常规果园管理方式(CK)、黑色宽膜覆盖集雨保墒及黑色宽膜覆盖+集雨立体入渗3个处理的产量与果实品质等性状。结果表明,与常规果园管理方式相比,黑色宽膜覆盖+集雨立体入渗处理平均单果质量增加13.2%,单株产量增产17.2%,果实硬度显著降低4.9%;含水量高3.4百分点,可溶性固形物含量、有机酸含量、可滴定酸含量及总糖含量分别提高7.2%、34.1%、182.1%、28.9%。说明在黄土旱塬苹果园采用黑色宽膜覆盖+集雨立体入渗技术能起到较好的土壤蓄水保墒作用,使果实产量与品质增加明显。

[Abstract]
With Changfu 2 as an indicator cultivar, the effects of rainwater harvesting and soil moisture conservation measures on the yield and quality of apples on Loess Plateau were studied through years of continuous positioning observation. The yield and fruit quality of conventional orchard management(CK), black wide-film mulching for rainwater harvesting and black wide-film mulching+three-dimensional infiltration of rain collection were compared and analyzed. The results showed that the average single fruit quality of black wide-film mulching+ three-dimensional infiltration of rain collection treatment increased by 13.2% compared with the control, the yield per plant increased by 17.2% compared with the control, and the fruit hardness was significantly reduced, which was 4.9% lower than the control; Water content was 3.4 % higher than that of the control group. Soluble solid content, organic acid content, titrable acid content and total sugar content were higher by 7.2%, 34.1% and 182.1%, respectively. The results showed that black wide-film mulching+ three-dimensional infiltration of rain collection technology could play a better role in soil water storage and moisture conservation in apple orchards on the Loess plateau, and increase the yield and quality of fruit significantly.
