前茬作物及栽培袋颜色对袋培西红柿的影响

摘要

[目的]为袋培技术在设施蔬菜生产中的进一步发展提供理论依据.[方法]对基质袋培条件下,不同前茬作物和不同栽培袋颜色对西红柿生长发育、产量及品质进行了研究.[结果]基质袋培的西红柿植株的营养生长接近在土壤栽培的西红柿.基质袋培的西红柿产量比土壤栽培的最高增产4％,同时基质袋培比土壤栽培节水39.6％,节约追肥量77.5％.基质袋培的西红柿维生素C含量、风味明显好于土壤栽培的西红柿,同时降低果实中的硝酸盐含量.[结论]基质袋培西红柿可取得更好的经济效益.%[Objective] This study aimed to provide a theoretical basis for the further development of bag culture in production of facility vegetables.[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.
