济宁稻区实行稻麦连作,对提高全区复种指数,增加粮食总产量起了重要作用。但是,多数麦茬稻的单产仍徘徊在600～700斤的中产水平,经济效益较低,增产潜力没有得到充分发挥。为此,我们于1982～1984年在济宁市郊区喻屯乡进行了万亩水稻中产变高产开发试验。三年来,麦茬稻的产量和经济效益逐年提高,1982年开发面积17,000亩,单产859.3斤,较开发前三年的平均单产566斤增产51.8％。1983年虽然年降水量仅有449.6毫

The implementation of rice-wheat continuous cropping in Jining Rice Area played an important role in improving the area’s multiple cropping index and increasing grain output. However, the majority of wheat stubble rice yields still hovering at a middle level of 600-700 jin, with low economic benefits and insufficient stimulation potential. To this end, we conducted in 1982 ~ 1984 in Jining suburbs Yutun Township million mu of rice yield middle high yield development test. In the past three years, the output and economic benefits of stubble rice have been increasing year by year. In 1982, the area under development was 17,000 mu with a yield of 859.3 kilograms, an average yield of 566 kilos and an increase of 51.8% over the previous three years of development. Although the annual precipitation in 1983 was only 449.6 millimeters
