Abstract：Taking bacterial bran culture substrate as raw material and choosing 4 cultivation methods as pillow planting，flat planting，trough planting and hole planting，this paper studied the effects of different cultivation methods on physical and chemical properties of organic ecotype soilless culture substrate in desert area；and on watermelon growth，yield and quality．The results showed that after the first crop of watermelon was cultivated，the comprehensive performance of physical and chemical indexes in trough planting was optimal and watermelon yield was the highest．The sugar content in fruit center was 11.26%，but the input cost was also the highest．The one-time input before planting was 157 452.00 yuan · hm-2．The yield of watermelon in plain planting was lower than that in trough planting，but the one-time input cost was the lowest，only 34 920.00 yuan · hm-2．Therefore，when watermelon with high sugar content was choosen and under the condition of increasing bio-organic fertilizer，flat planting could be the preferred cultivation method with low cost for organic ecological soilless cultivation of watermelon in desert areas．
