Abstract:
Considering the problems of environment pollution by nitrogen and phosphorus leaching,in order to explore the suitable planting methods of greenhouse tomatoes in winter-spring,effects of different planting methods on root growth,yield,nutrient uptake and spatial distribution of nitrogen and phosphorus nutrients of tomato ‘Langting’ were studied under four planting methods of 1.0 m flat-cultivation,0.5 m ridge-cultivation,1.0 m ridge-cultivation and 1.5 m ridge-cultivation by greenhouse field experiment.The results showed that compared with conventional 1.0 m ridge-cultivation,tomato yield,nitrogen absorption and phosphorus absorption was raised by 10.46%,7.78% and 20.35%,respectively,under 1.5 m ridge-cultivation.At the same time,root length,root length of 0
