不同施肥水平对绞股蓝生长的影响

[目的]探究不同肥力对绞股蓝生长情况的影响。[方法]采用半控制试验生态学方法,对绞股蓝施以不同浓度水平的肥料。[结果]施肥水平在一定范围内的提高有利于绞股蓝的生长。其中,施有机肥45000 kg/hm2的官田坝2号地的长势最好,不施底肥的地块最差。在相同的施肥条件下,不同品系的生长情况不同。[结论]一定的施肥水平可以加强绞股蓝的生长。

Effects of the Level of Fertilization on the Growth of Gynostemma pentaphyllum (Thumb)Makino

[Objective]The aim was to explore the response of G.pentaphyllum' s growth to soil fertility.[Method] Using the semi-controlled experimental method,different levels of fertilization were applied to G.pentaphyilum.[Result]The increase of the fertility was benefit to the growth of G.pentaphyllum.On the field Guantianba No.2 which was applied fertilizer 45 000 kg/hm2,the growth was the best,while the one without applying basic manure was the worst.Moreover,under the same applying condition,the growth of different breeds was different.[Conclusion] Certain level of fertilization could promote the growth of Gynostemma pentaphyllum(Thunb) Makino.
