我省有些水源不足的低洼地区,种植插秧稻往往会遇到雨季推迟的情况而失去栽、管季节,种植早作物又易受涝渍,致使秋粮产量一直低而不稳。针对这个问题,1984年我们进行了麦茬水稻直播栽培技术的研究,结果表明旱直播稻比插秧稻节水、省工一半左右,一般亩产350公斤左右,百亩连片丰产方亩产超过400公斤,最高田块达511.4公斤。麦茬水稻直播,就是在麦收后先浅灭茬而后播种,播前种子要吸足水分并晾干,采取机播或耧播。主要栽培技术如下:
In some low-lying areas in our province where insufficient water resources are available, the planting of transplanting rice often loses its cultivation due to the delay of the rainy season. In the autumn, the planting of early crops is also susceptible to waterlogging, resulting in low and unstable autumn grain output. In response to this problem, we conducted a research on direct seeding cultivation of wheat stubble in 1984. The results showed that drought-sowing direct-sown rice saves water by about half compared with rice transplanting and generally yields about 350 kg per mu. Kg, the highest field of 511.4 kg. Rice stubble broadcast live, that is, after the wheat harvest first shallow stubble and sowing, sowing seeds before sowing enough water and dried to take machine or sowing. The main cultivation techniques are as follows:
