摘要
1990—1991两年的百万亩杂稻高产试验、示范工程,共完成面积232.2万亩,平均亩产529.6公斤,总产较常年增加13.92万吨,创历史最高水平,其经济效益显著。采取的主要技术措施是:选用优良组合,培育壮秧,高质量栽插,加强肥水管理,及时防治病虫害等。
2.32 millions mu hybrid rice for high yield was demonstrated out in 1990. 1991. The average yield achieved 529.6 kg per mu and the total output increases by 0.14 million tons more than that of ordinary year. It was the highest yield and significant economic benefit in history in this region. The main technical measures were applying hybrid rica combination with high yield capacity, fostering healthy seedling, transplanting according to high specifications, fertilizing and irrigating adequately and controlling deseases and pests in time.
