摘要
于7—9月脐橙果实膨大期,连续达10 d晴天,进行树盘灌水,调查果实体积增长量和株产量。结果表明:灌水处理果实净增量曲线波动较未灌水处理的小,而且曲线高峰与低谷出现的时间和谷值有区别;8月上中旬,灌水处理曲线快速升高,而对照曲线逐步下降;平均株产量灌水处理(17.17 kg)大于对照(12.57 kg)。
Trees were crown irrigated after more than 10 sunny days ,during fruit-development stage（from August to September） ,volume growth and yield were researched.The results showed that irrigation treatments had less fluctuation compared with CK.Furthermore ,curve peak and low ebb were different in appeared and valley value.The curve of irrigation treatments rapidly increased in the first and second ten days of August,and the average yied（ 17.17 kg/plant）was higher than that of CK（ 12.57 kg/plant）.
