微润灌溉对日光温室番茄生长及水分利用效率的影响
Effects of the tomato growth and water use efficiency in sunlight greenhouse by moistube-irrigation
摘要
Abstract
A comparative test between moistube-irrigation and drip irrigation was conducted to study the effect of the tomato growth and water use efficiency in sunlight greenhouse by the new irrigation method of moistube-irrigation .The re-sulted showed that:The dynamic change of soil moisture by drip irrigation was more than the moistube-irrigation,the maximal amplitude of variation of drip irrigation has reached 60 .9%,but the soil moisture by the moistube-irrigation was basically maintained about 20%.Up to the end of growing season,the plant height and stem diameter by the moistube-irrigation was higher than drip irrigation 6 .36%and 3 .1 1%respectively,so the moistube-irrigation was more favor to plant growth .Meanwhile the daily variation of the tomato photosynthetic rate by two treatments was similar to bimodal curve,the leaf transpiration rate and daily change of the stomatal conductance was shown a single peak curve .The crop yield of drip irrigation was 98 654 .45 kg·hm-2 and for moistube-irrigation was 99 142 .25 kg·hm-2 .For the water use efficiency,drip irrigation and moistube-irrigation was 53 .33 kg·m-3 and 60 .42 kg·m-3 respectively,so whether the yield or the water use efficiency,the moistube-irrigation was total better than the drip irrigation theatment .Under these two irrigation methods,the water consumption rules were rather,but the water consumption by the drip irrigation was big-ger than the moistube-irrigation .关键词
