植株调整是蔬菜生产过程中的重要技术措施,通过对植株进行整枝、打杈、摘心、疏叶、支架、绑蔓、疏花疏果、保花保果等机械和物理措施来调整植株生长发育时间、空间定位,调整株型和枝、叶、果的分布,改善蔬菜群体的通风透光条件,截获更多的光能、二氧化碳和氧气,提高光合效率,平衡生殖生长和营养生长的关系,调节生物学产量和产品器官的关系,延长生长期和产品收获期,以达到蔬菜高产、优质、高效的栽培目的。1.番茄整枝番茄主茎长到一定叶数后,每个叶腋间都可生出侧芽(枝),以后侧枝上每个叶腋间又可生出二级侧 Plant adjustment is an important technical measure in the process of vegetable production. Plant growth and development can be adjusted by mechanical and physical measures such as pruning, twigs, topping, leaf loosening, scaffolding, entanglement, thinning, flower preservation and fruit preservation Time and space orientation, adjust the plant type and branch, leaf, fruit distribution, improve the ventilation of vegetables, light conditions, intercept more light energy, carbon dioxide and oxygen, improve photosynthetic efficiency, balance the relationship between reproductive growth and vegetative growth, regulation Biological yield and the relationship between products and organs, to extend the growth period and product harvest period, in order to achieve high yield of vegetables, high quality and efficient cultivation purposes. 1. Tomato pruning tomato main stem to a certain number of leaves, each leaf axillary buds can be generated (branches), and later on each side of the axillary axils can produce secondary side
