随着油菜生产的发展,产量要求愈来愈高,油菜倒伏问题也日益突出,现己成为发展高产油菜栽培中一个严重障碍因子。为了解决这一问题,我们对倒伏油菜的各种表现进行了分析,并于1978—1982年先后进行了大田和盆栽试验。试验设不同栽培方式(移栽与直播)、不同播期(早播与晚播)、蹲苗与不蹲苗以及不同苗势(大苗、疯长苗、大壮苗、弱小苗)、不同施肥方法、不同密度等处理,从中考察不同栽培条件与生长发育和倒伏的关系,以图进一步研究增强油菜抗倒能力的途径与措施。
With the development of rapeseed production, the production requirements are getting higher and higher. The problem of rape lodging is also increasingly prominent. Now it has become a serious obstacle in the development of high-yield rape cultivation. In order to solve this problem, we analyzed the various manifestations of rapeseed and conducted field and pot experiment successively in 1978-1982. The experiment set different cultivation methods (transplanting and direct seeding), different sowing dates (early sowing and late sowing), squatting and non-squatting seedling and different seedling emergence (big seedling, crazy seedling, big strong seedling and weak seedling), different fertilization methods Density and other treatments, the relationship between the different cultivation conditions and growth, development and lodging was investigated in order to further study ways and measures to enhance the lodging resistance of rapeseed.
