“宽行密株”是广东省近年来在水稻种植技术上一项重要改革。去年,我们与红心农科队一起,在晚稻生产中进行了宽行密植的试验考查,取得了可喜的增产效果。现将试验考查结果简介于下:综观六个不同密植规格的对比试验结果,以6×2.5为最好。从产量状况看:4×3亩产405斤,5×3亩产436.7斤,6×2.5亩产467.6斤。6×2.5比4×3增产15.5%,比5×3增产7.04%。 “Broad-line and tight-line” is an important reform in Guangdong’s rice cultivation technology in recent years. Last year, together with the Hongxinnongke Kebei team, we conducted a wide range of experiments on the planting of broad-leaved rice in the production of late rice and achieved encouraging results. Now the test results are summarized below: Looking at the six different close planting specifications of the comparative test results to 6 × 2.5 for the best. From the production situation to see: 4 × 3 mu 405 kg, 5 × 3 mu yield 436.7 kg, 6 × 2.5 mu 467.6 kg. The yield of 6 × 2.5 to 4 × 3 was 15.5%, which was 7.04% higher than that of 5 × 3.
