番茄的枝叶生长与开花结实,二者既矛盾又统一。一般来说,早熟的自封顶类型,因花果出现较早,果实在发育过程中需要较多的养分,因而生殖生长对营养生长的抑制作用较大。在栽培过程中,如果管理不当,往往会出现生长前期营养物质大量流向花果,枝叶生长受到强烈抑制,出现“坠秧”早衰现象。由于植株早衰,无足够的同化物质供给果实膨大,因此果实表现个小量少,且出现一些豆大的不膨大“僵果”。这种现象出现后,虽然有少量“坠秧”会提前着色,但早期产量,尤其是总产量受到严重影响。因此,要使番茄既早熟又高 Tomato growth and flowering branches and leaves strong, both contradictory and unified. In general, the precocious self-captive type, due to early emergence of flower and fruit, the fruit needs more nutrients in the development process, so reproductive growth inhibition of vegetative growth. In the cultivation process, if not properly managed, tend to appear before the growth of nutrients flow to a large number of flowers, foliage growth was strongly inhibited, there “falling seedling” premature decline phenomenon. Due to premature aging of plants, there is not enough supply of assimilation material to enlarge the fruit, so the performance of a small number of fruit, and some large non-blooming “stiff fruit.” After this phenomenon appears, although a small amount of “seedlings” will be colored in advance, the early output, especially the total output, has been severely affected. Therefore, to make tomatoes both early and high
