Effects Of Different Water And Fertilizer Treatment On Growth And Fruit Quality Of LingWu Long Jujube

Using Zizyphus jujube Mill.cv.Lingwu changzao as experimental material, the experiment with two factor randomized block design to set the irrigation amount was825m3/hm2(A1),1110m3/hm2(A2),1380m3/hm2(A3) three levels, fertilization of180kg/hm2(B1),240kg/hm2(B2),300kg/hm2(B3) three levels, a total of9treatment combinations.Determination of Zizyphus jujube Mill.cv.Lingwu changzao growth index (jujube hanging length, jujube hanging diametern, jujube hanging leaf number,leaf area leaf dry weight) and fruit quality, in different conditions, different irrigation water and fertilizer treatments on growth and fruit quality of Zizyphus jujube Mill.cv.Lingwu changzao. In order to determine the influence, drip irrigation and fertilization amount. The results show that:1.Irrigation, fertilization of300kg/hm213801380m3/m2in leaf area, leaf fresh weight, leaf dry weight net growth is more;irrigation, fertilization of180kg/hm1110m3/hm2processing(jujube hanging length, jujube hanging diametern, jujube hanging leaf number growth is relatively high; Zizyphus jujube Mill.cv.Lingwu changzao leaf on average14.22%of total potassium content is adequate, the total phosphorus content of0.73%for total nitrogen content1.76%, short, irrigation, fertilization of240kg/hm21110m3/hm2with the nitrogen content is the highest leaf thickness.2.The content of chlorophyll of Zizyphus jujube Mill.cv.Lingwu changzao was of S typecurve changes with time, in addition towater transpiration rate,leafutilization efficiencyand photochemical quenching coefficient of variation rough between each treatment significantly.differences mother photosynth eticindexes are notsignificant The transpiration rateof irrigation,fertilization treatment240kg/hm21110m3/hm2net reduce theamount is maximum,the water use efficiency and photochemical quenching coefficient maximum coarse net growth.3.Irrigation, fertilization of180kg/hm21380m3/hm2treatment of Zizyphus jujube Mill.cv.Lingwu changzao is a maximum of8.1%; Zizyphus jujube Mill.cv.Lingwu changzao fruit transverse and longitudinal irrigation moderate size; irrigation,fertilization of240kg/hm21110m3/hm2treatment yields the highest27.5kg/strain; irrigation, fertilization1110m3/hm2the amount of240kg/hm2processing, fruit soluble solids content was the highest; irrigation amount1380m3/hm2, fertilization of180kg/hm2treated fruit sugar content, vitamin C content is the highest, the lowest sugar acid ratio.To sum up, the irrigation1110m3/hm2,240kg/hm2, fertilization and irrigation, fertilization1380m3/hm2,180kg/hm2treatment can Promote Zizyphus jujube Mill.cv.Lingwu changzao growth, improve fruit quality, and can be popularized in production.
