为指导骏枣生产，提高效益，采用随机区组排列方法，研究了不同灌水量对骏枣幼树生物量差异（地径、株高、侧枝、根系）及结果情况（株产、果形指数、产量）的影响。结果表明：枣树地径生长量明显随灌水量的增加而增加，于6月24日枣头摘心后，基本全年株高生长结束，说明枣树的节间拉长生长较为有限；须根数及长度在8月后增加较多，在数量上以≥2mm根系为主，长度上主根不及须根；在果型指数方面，果实横径的变化量大于纵径的变化量；处理1（380m3）灌水量最小，而产量最高，达17．7t·hm-2，相比处理4（500m3）增产78．8％，节水24％，说明在红枣果实生长发育过程中，应将灌溉量控制在一定的范围。

In order to guide Jun jujube production and improve economic performance ,using random district group arranged method ,the effects of on Jun jujube tree biomass different irrigation volumes (ground diameter , plant height ,lateral branch ,root)and fruiting (yield per plant ,fruit shape index ,yield)were studied .The results showed that growth volume of jujube was obvious increasing with irrigation volume increaseing ,plant height growth was end after June 24 ,internode growth was limited ;the number and length of fibrous root increased after August ,the number of root ≥2 mm mainly ,the length of taproot was less than fibrous root ;in fruit type index aspects ,changes of fruit transversed diameter greater than longitudinal diameter ;irrigation water volume of treatment 1(380 m3 )was minimize ,but yield was the highest for 17 .7 t·hm-2 ,increasing yield was 78 .8%than treatment 4(500 m3 ) ,water saving was 24% .In jujube growth and development ,should control irrigation volume .
