水稻种植,在我国具有悠久的历史,稻作种植的面积、产量均居世界第一。在水稻的不同生长期,进行有促有控的水、肥培管技术,对水稻高产稳产起着明显的作用。现代灌溉技术,突破了传统的水层管理,实现了节水高产、优质、高效的控制灌溉技术,以节约灌溉,降低农本,减少能量的消耗,增加植株能量的积累,达到最高的灌溉水生产效率。 1 控制灌溉的特点 水稻的各个生育期不同,对水分的需要有不同的敏感度,必须采取适时、适量的水分供应,才能调整水稻生态的条件和
Rice cultivation has a long history in our country, the area planted with rice and the output rank first in the world. In different growth stages of rice, water and fertilizer control techniques have been developed, which play a significant role in the high and stable yield of rice. Modern irrigation technology, breaking the traditional management of the water layer to achieve a high water-saving, high-quality and efficient control of irrigation technology to save irrigation, reduce agricultural costs, reduce energy consumption, increase plant energy accumulation, to achieve the highest irrigation water Productivity. 1 Control of Irrigation Features Rice has different growth periods and different sensitivities to the needs of water. It is necessary to take appropriate and timely water supply to adjust rice ecological conditions and
