鄂晚3号是近年来推广的一个迟熟偏早的双季晚稻良种。为了探索其增产性能,1975年我们结合教学在三江公社彭鲁大队第五小队种植了1.06亩丰产田,平均亩产741.5斤。在丰产试验中,我们对鄂晚3号和农垦58的某些生育性状进行了系统观察和比较。观察内容和方法是: 秧田期:两个品种各标定有代表性的秧苗20株,观察其出叶进度,每片叶全展后量取叶长叶宽,计算叶面积。 本田期:将秧田定株观察的秧苗,整株拔起,移入大田,按一般生产上的丛栽方式,各栽20丛,每丛夹插一株,平均每丛共栽 E 3 late late in the promotion of late late rice late rice varieties. In order to explore its yield performance, in 1975 we combined teaching in the Sanjiang commune Penru Brigade fifth team planted 1.06 acres of high yield fields, the average yield of 741.5 kg. In the high yield test, we systematically observed and compared some fertility traits of No 3 and No. The contents and methods of observation were as follows: Seedling stage: 20 representative seedlings were screened for each of the two cultivars. The progress of leaf emergence was observed. After each leaf was fully expanded, leaf length and leaf width were taken and the leaf area was calculated. Honda period: seedlings observed seedling plant, the whole plant up, moved into the field, according to the general production of Cong Cong way, the planted 20 plexus, each Cong folder inserted a plant, an average of each Cong Gongzhu
