为什么要进行栽培密度试验?栽培密度试验主要是研究作物的田间配置方式与群体结构,以提高光能利用率,并协调单位面积穗、粒、重之间的关系,从而取得高额的经济产量.由于新的改良品种不断出现,以及从株型、生产效能等方面的改善,因而使相应增加密度、提高叶面积系数,进一步获得高产成为可能,这“两杂”作物方面更为明显.为此,有必要随同新品种的育成推广,立即进行栽培密度试验.
Why planting density test? Cultivation density test is mainly to study crop field configuration and population structure in order to improve the utilization of light energy, and coordinate the relationship between the panicle, grain and weight per unit area, so as to achieve high economic output Due to the continuous emergence of new improved varieties and the improvements in plant type and production efficiency, it is possible to increase the density, increase the leaf area coefficient and further increase the yield, which is more obvious in the “two hybrid” crops. This, it is necessary with the promotion of new varieties of breeding, planting density test immediately.
