| 为研究柱花草(Stylosanthes guianensis)浸出液对荔枝(Litchi chinensis)幼苗生长的影响，试验以4种不同浓度的柱花草浸出液根施荔枝幼苗，观测荔枝幼苗生长的情况。结果表明：4种浓度柱花草浸出液对荔枝幼苗生长均有促进作用；柱花草浸出液处理可使荔枝植株增高，叶片数增多，叶面积增大，叶片叶绿素相对含量(SPAD)和全N、全P和全K的含量增加；浓度为25.0 mg/mL的柱花草浸出液处理效果最佳。 |

| The purpose was to study the effects of Stylosanthes guianensis extracts on growth of litchi seedlings. In this experiment, four different concentrations aqueous extracts of Stylosanthes guianensis were used to root application of litchi seedlings and to observe its effect on growth of litchi seedling. The results suggested that the four concentrations aqueous extracts from stylosanthes guianensis promoted growth in litchi. And extracts from stylosanthes guianensis could increase the height of litchi plants, the number and the area of leaves. The content of SPAD, total N, total P and total K were also increased by the extracts from Stylosanthes guianensis. The concentration of extract was 25.0 mg/mL had the best effect on growth of the seedlings. |
