Abstract:: In order to explore the coupling effect of water and fertilizer under the condition of compound organic fertilizer in the arid desert area of Ningxia,early maturing musk melon was used as test materials,the eco-friendly water and fertilizer supply model combining water and fertilizer integration technology and bio-organic fertilizer combined with fertilizer application was put forward.The yield and quality of melon were studied by different irrigation quota,compound fertilizer and bio-organic fertilizer application.The regression model of single factor and two-factor interaction on yield and quality of melon was established.The results showed that the effect of yield (Ym) was the order of compound fertilizer (F)>water(W)>bio-organic fertilizer(O),the contribution of quality(Qm) was bio-organic fertilizer(O)>water(W)>compound fertilizer(F),the interaction effect of two factors on yield was WF>WO>FO,and the effect of quality(Qm) was WF>WO>FO.Through the comprehensive analysis of single factor and two-factor coupling,the ecological environment-friendly fertilization model of melon irrigation and compound fertilizer combined with bio-organic fertilizer was obtained when the yield of melon was above 42 000 kg·hm-2 in Ningxia arid desert area.The amount of fertilizer was 1 591.0-1 659.3 m3·hm-2,the dosage of compound fertilizer was 580.7-593.0 kg·hm-2,and the amount of bio-organic fertilizer was 182.5-257.4 kg·hm-2.
