Abstract: This article gives a systematic study of the propagating law of Rattus norvegicus family. The result shows:that Rattus norvegicus can propagate all the year; for each adult female the average pregnancy times are as many as 9.96 each year,and each time an average of 6.94 baby Rattus norvegicus are borne;the surviving rate for the young in autumn is the highest(64.6%), and the lowest in winter(32.5%), with sharply difference during the four seasons.(F=4.199,P<0.05)The peak pregnancy rate is in March to September,and it is obvious positively correlated with the average temprature and rainfall.(rtemprature=0.783,p<0.01,rtainfall=0.921,P<0.01) It also has some relationship with such factors as plant changing,crops riping and the number of natural enemies.
摘要: 对褐家鼠种群繁殖规律的研究结果表明:该鼠可全年繁殖,每只成雌一年妊娠9.96次,每胎产仔6.94只,其幼鼠相对存活率秋季最高(64.6%),冬季最低(32.5%),各季节间的差异具有显著性(F=4,199,P<0.05)。妊娠率高峰在3~9月份,与平均气温?降水量呈高度正相关(r气温=0.783P<0.01,r降水=0.921P<0.01),与植物变更?作物成熟?天故多少等因素也有一定关系。
