摘要
降雨量是影响丰宁满族自治县山杏产量的主导气象因子。降雨量大,则产量高,降雨量小,则产量低。为此,提出了提高山杏产量的几项技术措施。
Rainfall was observed to be the leading meteorological element affecting the yield of Siberian apricot (Prunus sibivica) in Fengning County of Hebei Province. While a sufficient amount of rainfall would result in a bumper crop; an inadequate quantity usually led to a poor harvest. Therefore, some technical measures for a high yield are su ggested.
