摘　　要：用7个早籼品种在屯溪、芜湖、安庆、合肥各分四期播种.其中,4月6、16、26日播种的早籼出糙率、精米率和整米率变化小;6月26日或7月6日播种的加工品质有显著改善.结果表明,影响早籼加工品质的主要气候因素是灌浆成熟期的温度.The milling quality of 7 early indica rice cultivars grown in Tengxi,Wuhu, Anqing and Hefei were investigated in 1988. The brown rice,milled rice and whole rice yield sowing on April 6, 16, 26 were slightlychanged, and sowing on June 26 or July 6 greatly improved. The pathand stepwise regression analysis indicated that the temperature duringgrain ripening was the major climatic factor affecting the milling qua-lity.
