研究探讨了喷施锌肥对空心菜的生长发育及体内含锌量的影响。结果表明 ,喷施0 .0 5%～ 0 .1 %浓度的锌肥能促进空心菜的生长发育 ,具有显著的增产效应 ,施用过量则会得到相反的结果 ;空心菜对锌的吸收与喷施浓度呈极呈著的正相关 ,且随着喷施浓度的增加叶中的锌浓度增加较茎中的快
The effects of spraying Zn fertilizer on the growth and development and the zinc content of The results showed that spraying 0.05-0.1% zinc fertilizer could promote the growth and development of water spinach, and had a significant yield-increasing effect. The over-application of zinc fertilizer would give the opposite result. The zinc absorption and spraying concentration Was a very significant positive correlation, and with the spraying concentration increased in the leaves of zinc concentration increased faster than in the stem
