1956年我们进行連作晚稻移栽期试验时,发现不同移栽期,秧齡愈长,移栽愈晚,植株产生不同程度的分枝现象,这种分枝多半是从地上茎节葉腋间着生,由腋芽生长而成,这些分枝並且同样具有抽穗结实的能力。试验时我们所採用連作晚稻品种分秈、粳两组,秈型品种为“晚成”,粳型品种为“背晚”,均係当地选出的農家种;同在5月30日播种,在8/7、8/17、8/27三期分期移栽,秧齡日数为69—79—89天;根據观察,在各期生育过程中,8月7日移栽,僅分蘖节位较高(在9—8节间 In 1956 we conducted continuous cropping of late rice transplanting test found that different transplanting period, the longer the seedling age, transplanted later, the plants produce varying degrees of branching, the branches are mostly from the ground stem leaf axillary intercourse, By the axillary buds grow, these branches and also have the ability to erect. In the experiment, we used the continuous cropping of late rice varieties as indica and japonica, the two indica varieties as late blooming and the japonica cultivar as “dusk and lateness”, all of which were selected by local farmers. On the same day, In the 8/7, 8/17, 8/27 three-stage transplanting, the number of seedling days was 69-79-89 days. According to the observation, during the period of fertility, transplanting was conducted on August 7, only the tiller node was High (between 9-8 knots
