杂交水稻的现状杂交水稻是我国培育成功的一项具有世界领先地位的农业科研成果。杂交水稻大面积应用生产,对提高我国水稻产量起了重要作用。由于杂交水稻具有明显的杂种优势和较广的适应性,经济效益高,因此,杂交水稻在我国发展极为迅速。1973年实现“三系”配套;1974年培育出第一套有生产价值的杂交组合;1975年种植5600余亩;1976年为208万亩;1977年为3200多万亩;1978年为6500多万亩;1979—1981年每年保持在8000 Status of Hybrid Rice Hybrid rice is a successful agricultural research project in the world with a leading position in the world. Large-scale application of hybrid rice production, rice production in China has played an important role. Because hybrid rice has obvious heterosis and broad adaptability, high economic benefits, therefore, hybrid rice is developing very rapidly in our country. In 1973, it achieved the “three lines” facilities. In 1974, the first hybrid production line with productive value was cultivated. In 1975, more than 5,600 acres were planted; in 1976, it was 2,080,000 acres; in 1977, it was more than 32,000 acres; in 1978, it was more than 6,500 Mu; 1979-1981 each year at 8000
