1976年我区水稻平均单产434斤,为全省最低产区。此后生产上采取推广杂交稻及其高产栽培技术体系,同时改善生产物质条件,只短短的五,六年间使水稻单产达到全省的先进水平,1982年全区水稻单产813斤,其中杂交稻千斤田近百万亩,平均单产900多斤。1983年徐州市所辖六县杂交稻面积已占稻田总面积的73％,并出现一批杂交稻千斤县,杂交稻在淮北的增产效益是肯定的。但在几年的实践中我们
In 1976 my average yield of rice in the region 434 kg, the province’s lowest producing areas. Since then, the production of hybrid rice and its high-yielding cultivation technology system has been taken into consideration. At the same time, material conditions for production have been improved. Only a short period of five to six years has allowed rice yield to reach the advanced level in the province. In 1982, the yield of paddy rice reached 813 kg, Kiln nearly a million mu, the average yield of 900 kilos. In 1983, the area of hybrid rice in six counties under the jurisdiction of Xuzhou City accounted for 73% of the total area of paddy fields, and a number of cluster hybrid rice appeared in counties. The yield increase of hybrid rice in Huaibei was affirmed. But in a few years of practice we
