灌溉方法对温室栽培番茄产量及水分利用效率的影响
Effect of different irrigation patterns on yield and water use efficiency of Tomato in Greenhouse
摘要
Abstract
A field plot experiment of tomato was conducted in the greenhouse to study the effect of three irrigation methods ,namely subsurface irrigation ,furrow irrigation ,drip irrigation ,on nutrient uptake ,yield and water use effi-ciency to tomato .Results showed that ,under the same conditions ,the yield of sub irrigation was 1 .9 times to furrow ir-rigation and 1 .2 times to drop irrigation ,drop irrigation was 1 .6 times to furrow irrigation at per cubic meter of water consumed .The soil water suction of drop irrigation was 24 .20 kPa ,subsurface irrigation was 23 .11 kPa ,and furrow irri-gation was 22 .01 kPa .The temperature of soil showed small differences .The nitrogen content of furrow irrigation was higher than drop irrigation and subirrigation .Drip irrigation could promote the absorption of nitrogen in tomato’s nutri-tional organs .The two methods could significant effect water saving and yield improving .Subsurface irrigation and drip irrigation are the ideal irrigation mode in tomato cultivation .关键词
