Growth characteristics of direct seeding rape in spring and after spring

(agricultural Wealth net) after the direct seeding rape entered the spring stage, like the transplanted rape, the vegetative growth accelerated, and from the vegetative growth before spring to the vegetative growth and reproductive growth at the bud bolting stage and the reproductive growth at the flowering stage, the vegetative growth basically stopped at the end of flowering stage. After the full flowering stage of direct seeding rape, the root activity decreased gradually, and the photosynthetic advantage of leaves was gradually replaced by the thickening pod layer. 40% of the rapeseed yield comes from the photosynthesis of the horned shell. In production, cultivation measures should be taken to improve the light conditions of the horn layer, so as to form large pods in the middle and upper part of the horn layer.
