众所周知,在各种蔬菜植物的生育过程中,都有一定的阶段性,可分为不同的时期,每一时期都有不同的特点,形成不同的器官。我们在栽培上就必须针对每个时期的不同特点以及前后时期的关系,采取相应的措施,满足植株在各个时期的不同要求,才能达到高产优质的目的。因此了解掌握不同蔬菜生育周期的规律,是制定高产优质栽培模式、进行栽培规范化的基础。本文探讨了洋葱整个生长发育过程的变化,进行了生育阶段的划分,拟为制定合理的洋葱栽培和采种技术提供理论依据。
As we all know, in a variety of vegetable plants fertility process, there is a certain stage, can be divided into different periods, each period has different characteristics, the formation of different organs. In cultivating, we must take corresponding measures for different characteristics of each period as well as the relationship between the previous period and the later period to meet the different requirements of plants in different periods in order to achieve high yield and high quality. Therefore, understanding the laws governing the fertility cycle of different vegetables is the basis for formulating high-yield and high-quality cultivation patterns and standardizing cultivation. In this paper, the changes of the whole onion growth and development process were discussed, and the division of the growth stage was carried out. It is intended to provide a theoretical basis for establishing a reasonable onion cultivation and seed collection techniques.
