摘　　要：研究典型大、小滴头流量对红枣果实纵横径、体积、叶绿素、叶一气温差、坐果率的影响，结果表明：成熟收获时，q=3．75L／h的大滴头流量处理的红枣纵径、横径、体积均大于q=2．00m的小滴头流量处理；小滴头流量q=2．00L/h的处理红枣叶片叶绿素含量均值比大滴头流量q=3．75L／h的处理高4．2％．说明用小滴头流量的滴灌管进行灌溉能够增加叶片的叶绿素含量．但经单因素方差分析得知2个处理差异并不显著：各处理灌水前。叶一气温差均值在1．75—2．10℃之间变化，浮动不大，且大滴头流量q=3．75肌的处理累积叶一气温差较小，说明该处理累积的受旱程度较轻；大滴头流量q=3．75L／h处理坐果率比小滴头流量q=2．00L/h的处理大20．4％。说明大滴头流量q=3．75L/h的灌水处理更有利于提高红枣的坐果率。且经单因素方差分析得知，2个处理差异显著。The effect of typical big,small water dropper flow on fruit vertical and horizontal diameter,volume,the chlorophyll and leaf-air temperature difference,fruit-set rate of red jujube were studied.The results showed that in the mature harvest time,longitudinal diameter,transverse diameter and volume of q=3.75 L/h of large water dropper flow treatment of red jujube were greater than q=2.00 L/h water dropper flow treatment.Leaf chlorophyll mean content of water dropper flow q=2.00 L/h in red jujube was higher than the big water dropper flow q=3.75 L/h treatment for 4.2%,which illustrated with small water dropper flow could increase the chlorophyll content of leaves,but by the single factor analysis of variance to learn that two treatments difference had no significance.Before the irrigation,leaf-air temperature difference was between 1.75~2.10℃,floating was not big,and accumulation of leaf-air temperature of largewater dropper flow q=3.75 L/h treatment was smaller,which illustrated the treatment had less victim.Fruit setting rate of big water dropper flow q=3.75 L/h treatment was higher than small water dropper flow q=2.00 L/h treatment for 20.4%,which illustrated big water dropper flow q=3.75 L/h treatment was more beneficial to improve the fruit setting rate of red jujube,and the single factor analysis of variance of the two treatments had significant difference.
