| Abstract: | The effects of water-fertilizer coupling on jujube yield and fruit quality under drip irrigation with plastic film were studied by filed test in Akesu area.With the means of mathematic statistic for fruit tree trial,the mathematical model for jujube yield and its main affecting factors water and fertilizer was established,which was as y=-12 670.96+40.54I+19.33F-0.034 9I2-0.008 93F2-0.000 043I·F.The results showed that under drip irrigation with plastic film the relationships between jujube yield and the irrigation norm or fertilizer were quadratic parabola.Appropriate water and fertilizer supply could improve the effect of increasing jujube yield,and the coupling effect of water and fertilizer was cooperation.But when water and fertilizer supply was excessive,the jujube yield decreased,and the coupling effect of water and fertilizer was antagonism.The effect of water-fertilizer coupling on fruit quality was not significant.When jujube yield per hectare reach the top,the best pattern was 579.7 m3/hm2 of irrigation and 1 081.2 kg/hm2 of fertilizer,which included N 254.29 kg/hm2,P2O5 190.64 kg/hm2,K2O 81.04 kg/hm2. |
