摘　　要：以张掖市文冠果省级文冠果良种基地进入结果初期的文冠果为研究对象,通过连续3年对基地内生长5年的文冠果单株产量等因子进行了调查,并对2年、3年、4年、5年、6年、7年不同龄级文冠果良种产量进行了测定;同时开展了文冠果种子播种品质的研究。结果表明,进入结果初期的文冠果单株产果1.085 kg,平均单果重32.18 g,果实出种率44.81%,平均单株产种483.88 g,平均单果产种14.42 g。随着文冠果生长年龄的增大,结实量也显著增加。The study took the Xanthoceras sorbifolia of Provincial Xanthoceras sorbifolia Forest Tree Fine Variety Base in Zhangye City as the research object,which were in the early fruiting stage.We investigated the factors for 3 years,such as yield per plant of Xanthoceras sorbifolia growing 5 years in the base,and measured the yield of fine variety with different ages(2 years,3 years,4 years,5 years,6 years,7 years).At the same time,the research on the seed sowing quality of Xanthoceras sorbifolia was carried out.The results showed that the yield per plant of Xanthoceras sorbifolia in the early fruiting stage was 1.085 kg,average weight per fruit was 32.18 g,seed production rate of fruit was 44.81%,and average seed yield per plant was 483.88 g,average seed yield per fruit was 14.42 g.With the increase of the growing age of Xanthoceras sorbifolia,the fruit yield also increased significantly.
