品种区域试验(简称区试),是鉴定新品种的特征特性,确定其最适宜的推广区域,探索新品种优化栽培技术的重要手段。尤其是地(市)县级的区试,以确定适宜本地推广的优良品种,摸索高产栽培技术为目的,直接为农业生产服务,其实用目的较强。注意以下几点,对搞好品种区试不无益处。 1.不要将种性差别太大的品种放在同一试验中。同种作物的不同品种,其栽培季节、生育期、抗性、耐肥性等都有一定差异。区试一般根据其性状的差异,分成若干个组来进行。例如,水稻可分 Regional trials of varieties (referred to as zone test), is to identify the characteristics of new varieties to determine the most appropriate promotion of the region, to explore new varieties of optimized cultivation techniques an important means. In particular, prefectural (city) district level test, in order to identify suitable for local promotion of fine varieties, to explore high-yielding cultivation techniques for the purpose of serving agricultural production directly, in fact, with strong purpose. Pay attention to the following points, to do a good job of variety test is not without benefit. 1. Do not put too much species diversity on the same test. Different varieties of the same crops, the cultivation season, growth period, resistance, resistance and so there are some differences. Regional tests are generally based on the differences in their traits, divided into several groups to carry out. For example, rice can be divided
