粮食要高速度发展,水稻要大上,杂优挑重担.一九七七年全国杂交水稻3200万亩,增产40亿斤,一九七八年全国杂交水稻面积7000万亩,增产70亿斤,在全国水稻应承担增产任务中均占较大的比重.根据全国杂交水稻面积可发展到一亿亩,要求承担增产任务更重.我省一九七七年杂交水稻243万亩,增产3亿斤左右,占全年增产三分之一左右.一九七八年800万亩,比常规品种增产一至二成,这说明了水稻在粮食增产中居举足轻重的地位,而杂优在水稻生产中是挑重担的,是大幅度提高粮食生产的重要途径.
Grain should be developed at a high speed, rice should be large, and miscellaneous goods should be taken as the burden. In 1977 32 million mu of national hybrid rice was increased by 4 billion kilograms. In 1978, the national hybrid rice area was 70 million mu, an increase of 7 billion kilograms In the country should assume the task of increasing production of the larger share.According to the national hybrid rice area can be developed to 100000000 acres, requires commitment to increase production tasks heavier.In our province in 1977 2430000 acres of hybrid rice, yield 3 Accounting for about one third of the increase in the whole year, and about 800 million mu in 1978, an increase of one to two percent over the conventional varieties, which shows that rice plays a decisive role in increasing grain output, while hybrid rice is used in rice production It is an important way to greatly increase food production.
