摘  要：
设置高、中、低3个灌溉水平和高密度、中密度、中低密度、低密度4种密度处理,研究灌水量和群体密度对籽瓜产量和生理参数的影响。结果表明,灌水量和群体密度对籽瓜产量、干物质积累及10粒长、宽均影响显著。高密度条件下籽瓜产量为3 093.27kg·hm-2,高于其他密度处理;中等灌水量籽瓜产量为3 154.58kg·hm-2,高于高、低灌水量。不同处理条件下籽瓜干物质积累均符合Logistic曲线。高密度下籽瓜最高叶面积指数、群体总光合势高于其他密度。不同灌水量籽瓜各生理参数变化规律不同。

摘  要：
An experiment was carried out to research influences of population density and irrigation quantity on physiological parameters and yield of seed-watermelon.Three treatments of irrigation were designed as high,middle and low,and four treatments of population density as high,middle,low and lower.The results showed that both population density and irrigation quantity had significant influence on yield,dry matter,grain length,and grain width.Yield of high density was 3 093.27 kg·hm-2,higher than the others,and yield of middle irrigation quantity was the highest,3 154.58 kg·hm-2,compared with high and low irrigation.Dry matter accumulation of all was fitted by Logistic models.Under the condition of high density LAI,population leaf area duration,photosynthetic productivity was higher than the other density.The trends of each physiological parameter varied with different irrigation quantity.
