在进行花生高产栽培规律研究过程中,为了明确高产花生群体植株外部生育变化与内部生育动态指标与产量的关系,需要进行一些测定工作。对于这方面工作我们以往做的不多,有些做法还存在不少问题,为了便于大家交流经验和共同提高,现把几种简单的生育动态规律的观察测定项目和方法介绍如下。 一、花生开花结实规律的观察及计算 方法通过开花结实规律的观察,进一步掌握高产田花生的开花、受精、结实的动态指标及其对花生产量的影响关系。
In the process of peanut high-yielding cultivation research, in order to clarify the relationship between the external fertility changes and the internal fertility index and yield in high-yield peanut population, some determination needs to be done. We did not do much work on this aspect in the past. There are still some problems in some approaches. In order to facilitate the exchange of experiences and common improvement, several simple observation and measurement items and methods for the development of fertility are introduced below. First, observe and calculate the law of flowering and fruiting of peanut Through the observation of the law of flowering and fruiting, the dynamic indexes of flowering, fertilizing and fruiting in high-yield peanut field and its influence on the yield of peanut were further mastered.
