| 摘 要： | 利用正交试验设计,研究了直播栽培的播种期、密度和氮肥用量3个栽培因子对甘蓝型双低高油油菜‘浙油18’植株的主要经济性状和产量的影响.结果表明,播种期对‘浙油18’的株高、一次有效分枝数、单株有效角果数、每角果实粒数和千粒重有显著影响；种植密度对一次有效分枝数、单株有效角果数和每角果实粒数有显著影响；氮肥用量对有效分枝部位,三因子对其他经济性状影响不显著.根据极差和F测验,三因子对‘浙油18’产量影响依次为播种期＞定植密度＞氮肥用量.随着氮肥用量增加,产量先增后减,差异不显著.提早播种、适当增加密度,产量显著提高.

| Abstract: | Effects of three cultural factors including seeding time,plant density and application amount of nitrogen on main traits and yield of direct-seeding rapeseed Zheyou-18 were studied using orthogonal test.The results showed that seeding time significantly affected the height,the number of primary affective branches,the total pods per plant,the grains per pod and the kilo-grain weight.Plant density significantly affected the number of primary affective branches,the total pods per plant and the grains per pod.M... |
