通过引进优良枣品种沾化冬枣、梨枣、骏枣,并以湖南省良种鸡蛋枣作对照研究,结果表明,在生长方面,3个枣品种均弱于鸡蛋枣;在结果方面,3个品种早果性和早期丰产性均优于鸡蛋枣,其中冬枣表现早果性好,梨枣、骏枣早期产量较高,沾化冬枣早期产量较低,但果实品质最优,果实病害最轻;梨枣在各个性能上均优于鸡蛋枣;骏枣单果是3个引进品种中最大的,果实品质尚可.

Study on Three Varieties Introduction of Jujube

'Zhanhua Dongzao' jujube,pear jujube,jun jujube were introducted into Hunan province.Through comparative study of them and local jidan jujube,the results showed that all the three varieties were weaker than jidan jujube on the face of growth,but all of them were earlier and had higher output in early stages than jidan jujube on the face of fruiting.In them,the premature birth date of 'Zhanhua Dongzao' jujube was earliest,but pear jujube and jun jujube had higher output in early stages.'Zhanhua Dongzao' jujube had lower output in early stages,but the quality of fruit was best and the diseases of fruit were lightest.Pear jujube was better than jidan jujube on all the faces reseached.The fruits of jun jujube were biggest in the varieties introducted,and the quality of fruit was passable.
