摘要
对隔沟交替灌溉在秋甘蓝、青花菜和大白菜上的应用效果进行了初步研究。结果表明:隔沟交替灌溉与传统灌溉相比,甘蓝、青花菜和大白菜的产量降低均不显著,但灌溉水生产效率分别提高33.5%、25.4%和62.0%,灌溉水生产效益分别增加43、28和51元.m-3,平均单株根干质量分别增加60.0%、34.1%和58.3%。
The effects of alternate-furrow irrigation were carried out in cabbage,broccoli and Chinese cabbage cultivation.The results showed that with new irrigation method,the yield didn't change obviously.For cabbage,broccoli and Chinese cabbage with new irrigation method,the irrigation water productivity increased by 33.5%,25.4%and 62.0%respectively;the dry weight of plant root increased by 60.0%,34.1%and 58.3%respectively;the economic efficiency of irrigation water increased by 43,28 and 51 Yuan·m^-3 respectively.
