摘要

[Objective]The paper was to study the effects of different plant densities on growth,yield and quality of mini-watermelon under soilless cultivation.[Method]Five planting densities were designed under double row planting with one main vine and one lateral vein in soilless cultivation,including 5.25×10^4,3.90×10^4,3.15×10^4,2.70×10^4 and 2.25×10^4 plants/hm^2.[Conclusion]Under the planting density of 3.15×10^4 plants/hm^2,the yield of mini-watermelon was the highest of 58.719 t/hm^2;the yield of plot was the highest of 260.97 kg;the central sugar content was the highest of 13.20%;the earliest date of harvest was June 1,ranking second;the fruit setting rate was 108.9%;the single fruit weight was 1.72 kg;and the malformed fruit rate was 0.48%.[Conclusion]Under soilless cultivation,3.15×10^4 plants/hm^2 is the best planting density.
