Effect of Different Soil Water-Fertilizer Supplying on the Yield and Fruit Quality to Cucumber in Solar Greenhouse

The experiment aimed to find the effect of different soil water-fertilizer application on the yield and fruit quality to the cucumber in solar greenhouse.The experiment had been done in north of Shanxi province in 2006 and 2007.There were six treatments of WhFh,WmFh,WlFh,WhFl,WmFl and WlFl,which had been randomly distributed in the plot which had been insulated by 2m depth of cement wall.The yield,WUE(water use effect),and cucumber quality of VC,NO-3-N,soluble protein and sugar content in different treatment had been analyzed.① NO-3-N content of all samples was lower than 432mg/kg(fresh weight),the cucumber quality in WmFh(soil water content was 75%～90%,fertilizer had been supplied 600kg/hm2 N and 420kg/hm2 P2O5) treatment was better than other treatment with higher soluble sugar,VC and the soluble protein content.② Cucumber yield increased with the water-fertilizer supply increased,WUE positively correlated with the fertilizer quantity and correlated negatively with irrigation mount.The WmFh treatment had got higher yield,WUE and better fruit quality production comparing with other treatments.
