本试验用20个早籼品种观察了移栽对生育的影响,并用其中4个品种通过多种移栽方式、不同播量不同叶龄期移栽、剪根移栽和去叶移栽等处理,研究了水稻从营养生长向生殖生长转换的变化规律,结果发现移栽能加速出叶进程,延缓生育转换时间,每移栽一次,幼穗分化大致延迟一个叶龄期,总叶数多一张左右,而抽穗时间略有提前。并且发现产量—移栽期曲线为一单峰曲线,其高峰因播量不同有很大差异。本文提出了移栽效应的概念,证明了移栽效应在水稻中的普遍性和品种间的特异性。文中对移栽效应的原理作了分析和讨论,并联系生产上经常出现的早穗、小穗和迟抽头、翘稻头等问题以及解决这些问题的途径,也作了简要的讨论。
In this experiment, 20 early indica cultivars were used to observe the effects of transplanting on reproductive development. Four kinds of cultivars were transplanted with different transplanting methods at different leaf seeding ages, The results showed that transplanting could accelerate the leaf process and delay the transfer time. After transplanting, the differentiation of young spikes was delayed by about one leaf period and the total number of leaves was one Zhang around, while the heading time slightly ahead. And found that yield - transplanting curve as a single peak curve, the peak due to different sowing are very different. In this paper, the concept of transplanting effect is put forward to prove the universality of transplanting effect in rice and the specificity among cultivars. In this paper, the principle of transplanting is analyzed and discussed, and the problems of early spike, spikelet, late-twitching, tilting head and so on, and the ways to solve these problems are also discussed in connection with production.
