苹果滴灌灌水定额试验研究

Experimental Study on Application Rate of Apple Drip Irrigation

本文介绍了苹果需水量的测定方法以及试验结果,分析了陇东旱塬区苹果各生育期的耗水规律,推算出了苹果树在降水保证率50 % 时幼龄树和盛果期树的灌水次数及每次的灌水定额,对推广应用滴灌技术,提高苹果产量和品质,节约用水,促进苹果生产具有实际意义。

This paper introduces a measuring method of apple water requirement and an experimental result, analyses the rules of water consumption for each growing period of apple in the tableland areas of Longdong. Irrigation times and irrigation norms of little flourishing trees under the ensuring of 50% precipitation, those have practice values to popularize drip irrigation, to increase yields and qualities, and to save water.
