Abstract: To study the effect of planting density on yield and quality of summer water spinach in the idle greenhouse, 4 planting densities, 20 cm×15 cm, 20 cm×10 cm, 15 cm×15 cm, 15 cm×10 cm, were employed in the experiment to investigate the variation of production, yield and quality of water spinach. The results showed that different planting densities had a certain influence on yield and quality of summer water spinach planted in greenhouse. The water spinach at the density of 20 cm×10 cm obtained the highest production and yield, and possessed lower nitrate content and higher soluble protein, Vc, dry matter content which improved the quality. Therefore, the large or small planting density of water spinach can not acquire high production, yield and quality. Only with an appropriate planting density, water spinach can obtain higher production, yield and the best quality at the same time.
