关于小麦分蘖的规律,理论上已经明确。本文是在大面积生产实践上,作了一些具体观察,从而加深了对小麦分蘖特性的认识,并在指导生产中发挥了一定作用。自1979年秋播以来,我们在不同年景,不同栽培条件下,结合各种试验,布点观察单株331株。现将资料整理如下: 一、大面积生产上小麦分蘖及成穗特点: 1.分蘖起始时间早,有效分蘖期短。从观察的单株中看出,大部分植株在3叶末4叶初开始分蘖,
On the law of wheat tiller, in theory has been clear. This article made some concrete observations in the practice of large-scale production, thus deepening the understanding of tillering characteristics of wheat and playing a certain role in guiding the production. Since the autumn broadcast in 1979, we have observed 331 strains of plants in different years and under different cultivation conditions in combination with various experiments. The data are now organized as follows: First, large-scale production of wheat tiller and ear characteristics: 1 tillering start time early, effective tillering period is short. Seen from the observed single plant, most plants begin tillering at the beginning of 4 leaves,
