摘要
针对冀西北坝上芸豆主产区,对不同水肥条件下芸豆的耗水量及产量进行了研究,为芸豆高产高效生产技术集成提供理论依据。研究结果表明,在鼓粒期及时灌水,可以促进子粒灌浆,达到增加产量的目的;与追肥相比,施用基肥平均增产38.0%,初花期追肥比鼓粒期追肥增产15.1%;基肥-鼓粒期灌水处理的水分利用效率最高,为7.2kg/(hm^2·mm)。
In the northwest of Hebei province, the effects of water and fertilizer conditions on water consumption and yield were studied, in order to provide theoretical basis for the common bean production. The results showed that irrigation in the seed filling stage could increase the yield. The average yield with base fertilizer treatment was 38.0% higher than that of the dressing fertilizer treatments. The yield of dressing fertilizer in the initial flowering stage was 15.1% higher than that in the seed filling stage. The water use efficiency of the base fertilizer and irrigation in the seed filling stage was the highest with 7.2kg/（hm^2·mm）.
