环剥植物树干韧皮部的成活探究

Exploration on survival after the plant bough bast was peeled circularly

绿色植物叶进行光合作用制造有机物,通过茎的韧皮部向下运输供给根的需要。通过课外探究将茎的韧皮部环剥一周后,被环剥树枝并不一定死亡。某些树种还会因有机物输送暂时受阻和积累而储存营养,在生殖季节供给果实营养,提高果实质量和产量。这一技术在果园发展应用上具有重要意义。

The organic matters were produced through photosynthesis by the leaves of the green plants and were transported down to meet the need of root through the bast of the stem.However,these plants weren't always been dead after the stem basts were peeled circularl fot a week.Some plants also could accumulate and store up the nutrition due to transportation block.And then these produced organic matters could be suppied to plant fruits in reproduction season.Consequently,it would improve the fruit quality and output.The technology would play a vital role in the development of orchard.
