稀土微肥对油茶植株生理指标及产果量的影响

Effects of rare-earth micro-fertilizer on plant physiological indexes and yield of Camellia oleifera Abel.

以油茶为试验材料,研究了稀土微肥对植物体叶绿素含量、可溶性蛋白质含量、核糖核酸酶的活性、光合速率、植株生长和产量的影响。结果表明,施用适量稀土微肥可以促进油茶春梢生长和叶面积增加,提高2年生叶片叶绿素、可溶性蛋白质含量,抑制核糖核酸酶的活性,增强光合速率,延缓3年生叶片的衰老,从而提高油茶的坐果率和单株产量。

The influences of rareearth microfertilizer on leaf photosynthetic rate,the content of chlorophyll(chl) and proteins,the activity of RNase,plant growth and yield in Camellia oleifera Abel.were tested.The results showed that the application of suitable rareearth microfertilizer would increase the content of chl and proteins in biennial leaf,inhibite the activity of RNase and improve photo synthetic rate,the percentage of fertile fruit and yield of Camellia oleifera Abel.
