目前,油菜正进入蕾薹期。油菜的蕾薹期是油菜早发稳长达到根强、秆壮、枝多,为争取角多、粒多、粒重奠定基础的关键时期,也是油菜吸收氮、钾养分最多的时期。此阶段氮、磷、钾营养供应充足与否,对单株有效分枝数和角果数有重要的影响。这个时期田间管理工作的重点就是促进油菜春发稳长,协调营养生产和生殖生长,争取枝多、角多、粒多、减轻病虫的危害。 At present, rape is entering the budding period. The rapeseed rapeseed period is the key period when the rapeseed grows steadily and reaches the root strong, stalks and branches, and lays the foundation for getting more horn, grain and grain weight. It is also the period when the rape absorbs nitrogen and potassium nutrients most. This stage of nitrogen, phosphorus and potassium nutrient supply sufficient or not, the effective number of branches per plant and fruit number has a significant impact. During this period, the key point of field management is to promote the stable growth of rape spring and harmonize the nutrition production and reproductive growth, strive for more branches, more corners and more grains, and reduce the harm of pests and diseases.
