本文采用回归设计和裂区设计相结合的方法，对油菜早熟品种栽培特性和密氮配置参数的研究表明：在产量构成因子中，每角粒数对产量的直接作用最大，千粒重通过每角粒数对产量的间接作用亦较大，且每角粒数和千粒重有一定的协同效应。栽培上应以较高的每亩有效角果数为基础，通过增加每角粒数提高千粒重来实现油菜增产。提出亩植1．40—1．53万株，施氮素8．4—9．0公斤为早熟品种的适宜密氮配置参数。在此范围内，常规种偏低限，杂交种偏高限。还比较了绵油6号、川油11和锦杂905之间的差异，明确栽培要点，可在实践中应用。
In this paper, a combination of regression design and split-plot design was used to study the cultivation characteristics and nitrogen allocation parameters of early-maturing rapeseed varieties. The results showed that the direct effect of grain yield per particle was the largest, The indirect effect of number on yield is also large, and there is a certain synergistic effect between the number of grains per corner and 1000-grain weight. Cultivation should be based on a higher number of effective per acre pod, by increasing the number of grains per hill to increase 1000-grain weight to achieve rapeseed yield. Proposed mu plant 1.40-1.53 million, nitrogen fertilizer 8.4-9.0 kg of nitrogen for the early maturing varieties of configuration parameters. In this range, the conventional species of low limit, hybrids high limit. Also compared the difference between Mianyou 6, Chuanyou 11 and Jinza 905, and clarified the key points of cultivation, which can be applied in practice.
