瓜类是属薄叶植物。其叶部组织比其它蔬菜类的叶子组织疏松,气孔较大,细胞壁薄,叶面多毛,而且它的生理过程中同化率强,蒸腾也强,其细胞液浓,渗透值很高,吸水力也强。其根多且浅,分布在20公分土层中。当666药剂与瓜类的叶面或其它部分接触时,极易渗透入组织中去,所产生的相互作用,极为旺盛。在植株没有足够的物质来源供应时,就加速了它的新陈代谢作用,产生植株的萎蔫与局部细胞
Melons are thin leafy plants. Its leaf tissue is more loose than the leaf tissue of other vegetables, large stomata, thin cell walls, follicular follicles, and its assimilation rate in the physiological process is strong, transpiration is strong, the cell density, high permeability, water absorption Strong. The root is more and shallow, distributed in 20 cm soil layer. When the 666 agent and melon foliage or other parts of the contact easily penetrate into the tissue, the resulting interaction is extremely strong. When plants are not supplied with adequate sources, their metabolism is accelerated, resulting in wilting of the plants and local cells
