蔬菜营养液育苗能加速蔬菜幼苗生长发育过程,提高幼苗质量,有利于早熟丰产。在营养液或基质中适当增加N P要素,能缩短苗龄,促进花芽分化。蕃茄营养液育苗于基质中增施磷肥,能加速幼苗营养生长,促进花芽分化;黄瓜营养液育苗,幼苗的叶片数、叶面积随着营养液中N P浓度的提高而增加,但NH_4—N含量不能过高,否则花芽分化延迟。
Vegetable nutrient solution seedling can accelerate the process of vegetable seedling growth and improve seedling quality, is conducive to early maturity and high yield. Appropriate increase in N P elements in the nutrient solution or matrix can shorten the seedling age and promote flower bud differentiation. The nutrient solution of tomato seedling increased phosphate fertilizer in the matrix, which could accelerate the vegetative growth of seedlings and promote the flower bud differentiation. The number of seedling and leaf area of cucumber nutrient solution increased with the increase of NP concentration in nutrient solution. However, the content of NH_4-N Can not be too high, or delayed flower bud differentiation.
