为研究库尔勒香梨幼果期不同水分处理对商品果率的影响,选取20年龄长势一致的库尔勒香梨树作为试验对象,分成3组,在幼果期分别以常规灌溉水量的60%(RDI-1)、80%(RDI-2)、100%(CK)进行灌溉,统计各组梨树2012—2014年的商品果率并加以分析研究。结果表明:受到水分调控的香梨平均硬度较正常灌溉低,可溶性固形物含量较正常灌溉高,综合商品果率较正常灌溉低,在幼果期以常规灌溉水量80%作为灌水定额的处理,可以节约生育期总用水量的5%,并兼顾商品果率和水分利用效率的要求,可以进行推广应用。
In order to study the effects of different water treatments on the fruit yield of young fruits of Korla pear, the 20-year-old Korla fragrant pear trees were selected as test subjects and divided into three groups. In the young fruit stage, 60% of the conventional irrigation water (RDI -1), 80% (RDI-2) and 100% (CK). The commercial fruit rate of pear trees in each group from 2012 to 2014 was calculated and analyzed. The results showed that the average hardness of pear under water regulation was lower than that of normal irrigation and the content of soluble solid was higher than that of normal irrigation. The fruit yield of integrated commodity was lower than that of normal irrigation. In the young fruit stage, 80% of normal irrigation water was used as irrigation quota, Can save 5% of the total water consumption during the growth period, taking into account the requirements of commodity fruit rate and water use efficiency, and can be popularized and applied.
