Résumé
The main objective of the effect of cultivation methods and irrigation quota for watermelon of arid region physiological characteristics,quality and yield,the research was conducted in Yield of Watermelon in Gravel-mulched Field Model in the Xiangshan Township of Zhongwei City in Ningxia.Choosing Jincheng No.5 as the test material,using direct seeding,self-rooted and grafted seedlings cultivation techniques,setting different irrigation quota,3 treatments were set as direct seeding(0 m3/667m2 ;6 m3/667m2 ;12 m3/667m2),grafted seedlings(0 m3/667m2 ;6 m3/667m2 ;12 m3/667m2)and the grafting(0 m3/667m2 ;6 m3/667m2 ;12 m3/667m2),comparative analysis of different cultivation methods and irrigation quota changes under the pressure of sand melon physiological characters,yield and quality and other performance indicators,selected arid sand melon cultivation methods suitable for the pressure and irrigation quota,the main results are as follows:1,Under the same irrigation quota and different cultivation methods,the grafted seedlings cultivation mode can make the Watermelon in Gravel-mulched Field early maturity and growth status,photosynthesis and yield were significantly higher than other cultivation methods.The comprehensive quality of direct seeding was higher than that of grafted seedlings,the effect was not significant,and the yield and water production efficiency were significantly lower than those of grafted seedlings.Taking into account the quality,yield and market factors,the grafted seedlings were suitable for cultivation methods.2,Under the same irrigation method,the growth and development status,photosynthesis and yield of the high irrigation quota were higher than those of the low irrigation quota.Although the irrigation water production efficiency of the low irrigation quota was higher than that of the high irrigation quota,the comprehensive quality was excellent in the high irrigation quota,but the effect is not significant,and the yield and the efficiency of group water production is less than the high irrigation quota ;comprehensive consideration,the 12 m3/667m2 is the suitable irrigation quota under the test conditions
