油菜花角期是植株生长发育最旺盛的时期。这时油菜植株内部养分运转,由开花以前的营养生长为中心到开花结角期逐步转到以生殖生长为中心。因此,这时的田间管理应以促进生殖生长为中心,防止植株早衰,保证果皮光合作用正常进行。达到角多粒重、活熟到老。 Rape angle is the most prosperous period of plant growth and development. At this time rape plant internal nutrient operation, from the vegetative growth before flowering as the center to flowering knot gradually transferred to reproductive growth as the center. Therefore, field management at this time should focus on promoting reproductive growth to prevent premature plant decline and ensure the normal photosynthesis of the peel. Reach angle and more weight, live to old.
