日前,由知名无水层灌溉专家、高级工程师奕永庆主持的“水稻无水层灌溉”科研项目获得成功。以往传统的水稻栽培方法蓄水层厚,而水稻生长多数时间并不需要这么多水,大量多余的水积留在田间,这不仅不利于水稻根系充分吸收氧气,影响水稻的成长、分蘖,也导致化肥和水的无谓流失,造 Recently, a well-known non-water layer irrigation experts, senior engineer Yi Yongqing hosted the “rice water layer irrigation” scientific research project succeeded. In the past, traditional aquaculture methods had thick aquifers. However, most of the rice growth did not require so much water and a large amount of excess water remained in the fields. This was not only unfavorable to the rice roots’ adequate absorption of oxygen, but also affected rice growth and tillering. Lead to unnecessary loss of fertilizers and water, made
