杂交水稻是我国继水稻矮化育种以后又一项处于世界领先地位的农业科研成果。近年来我县的生产实践充分表明,大力推广杂交水稻起到显著的增产效果。1982—1987年,全县推广面积27.46万亩,平均亩产334.3公斤,与常规稻平均亩产216.7公斤相比,平均亩增117.6公斤,增产54%,6年累计增产稻谷达32293吨。我县推广杂交水稻多年,虽然取得了一定的成效和不少的成功经验,但是发展速度还很慢,全县的种植面积也不大,种植面积较多的
Hybrid rice is one of the most advanced agricultural research achievements in the world after the dwarf breeding in China. In recent years, our county’s production practice has fully demonstrated that promoting hybrid rice has played a significant yield-increasing effect. From 1982 to 1987, the county had an area of 274,600 mu and an average yield of 334.3 kilograms per mu. Compared with the average per mu of 216.7 kilograms of conventional rice, the average acreage increased 117.6 kilos and an increase of 54%. The cumulative increase of paddy production in the past six years reached 32,293 tons. Although we have achieved some success and many successful experiences in popularizing hybrid rice for many years in our county, the development speed is still very slow. There is not much planted area and planting area in our county
