1营养生长与生殖生长农作物生长即包括营养体生长和生殖体生长。农作物营养器官根、茎、叶的生长称为营养生长。作物生殖器官花、果实、种子的生长称为生殖生长。营养生长和生殖生长以花芽分化为界限,把生长过程大致分为两段。花芽分化之前属于营养生长,之后则属于生殖生长期。但营养生长和生殖生长的划分并不是绝对的,因为作物从营养生长过渡到生殖生长之前,均有一段营养生长与生殖生长并进的阶段。
1 vegetative and reproductive growth of crop growth that includes vegetative and genital growth. Vegetative vegetative organs root, stem and leaf growth known as vegetative growth. Crops reproductive organs flower, fruit, seed growth is called reproductive growth. Vegetative and reproductive growth to flower bud differentiation as the boundaries, the growth process is broadly divided into two sections. Before flower bud differentiation is vegetative growth, then belong to reproductive growth period. However, the division of vegetative and reproductive growth is not absolute, since there is a period of vegetative and reproductive growth before crop transition from vegetative growth to reproductive growth.
