[Method] The effects of different previous crops and bag colors on the growth and development, yield and quality of tomato were investigated under the condition of substrate bag culture. [Result] The plant growth of tomato cultivated in bag was close to that of the tomato growing in soil. Under the condition of substrate bag culture, the yield of tomato was increased by as high as 4%, the irrigation water was saved by 39.6%, the fertilizer for drip irrigation was saved by 77.5%, the vitamin C content and the flavor of tomato were improved, and the content of nitrate in tomato was reduced compared with soil cultivation. [Conclusion] Substrate bag culture of tomato could achieve better economic benefits.展开更多
