近年来,我省针对不同生态地区发展杂交中稻的主要障碍因素,研究了对策,因地制宜地制定了趋利避害的栽培措施,积极发展杂交中稻,促进了水稻总产量的连年增长。1983年杂交水稻面积达2,062万亩,约占水稻面积的46%。平均亩产960斤。对全省水稻平均亩产跨过800斤起了重要的作用。我省东南部低海拔地区存在着常发性高温天气。1978年严重的高温曾使处于发展初期的杂交水稻受到
In recent years, according to the main obstacles in the development of hybrid mid-rice in different ecological regions, the province has studied the countermeasures, formulated the cultivation measures of avoiding disadvantages and actively developed hybrid mid-rice and promoted the annual growth of total rice output. 1983 hybrid rice area of 2062 acres, accounting for about 46% of the rice area. The average yield of 960 pounds. The average yield of rice across the province over 800 pounds played an important role. Low-altitude southeastern region of our province there is a frequent high-temperature weather. Severe high temperatures in 1978 had affected hybrid rice in its infancy
