不同滴灌灌水器对日光温室小西瓜生长、耗水和产量的影响

Impact of Different Drip Irrigation Emitters on Growth,Evaportranspiration and Yield of Solar Greenhouse Watermelon

以"红小帅"西瓜为试材,在重力滴灌条件下,以张力计控制灌溉起点,研究了保定华宇园林滴灌管、耐特菲姆片式滴头滴灌带和北京绿源片式滴头滴灌带3种不同的滴灌灌水器对温室小西瓜生长、耗水和产量的影响。结果表明:耐特菲姆片式滴头滴灌带处理的小西瓜耗水强度高于其它处理,产量以耐特菲姆片式滴头滴灌带处理最高,分别比北京绿源片式滴头滴灌带和保定华宇园林滴灌管增产8.48%、11.08%。因此,综合耗水量、产量等因素,耐特菲姆片式滴头滴灌带是日光温室栽培小西瓜比较适宜的滴灌灌水器。

Taking ‘Xiaohongshuai＇watermelon as material,impact of three different drip irrigation emitters on growth,evaportranspiration and yield of watermelon that grown in solar greenhouse was studied under gravity drip irrigation controlled by tension meters.The results showed that evaportranspiration of watermelon in drip line of Netafim with sheet-type emitter was higher than other treatments.Yield of watermelon in drip line of Netafim with sheet-type emitter ranked was the highest that was 8.48%,11.08% higher than that in drip line of Beijinglyuyuan with sheet-type emitter and drip tube of Baodinghuayu.So,drip line of Netafim with sheet-type emitter was the comparatively better drip irrigation emitter of watermelon grown in solar greenhouse.
