研究日照对宝石山上4种蕨类植物生长的影响 

【方法】以宝石山上常见的4种蕨类植物为观测实验材料。以实地观测法在四个梯度照度下，探讨光照对4种蕨类植物生长情况的影响。 

【结果】在照度500lux的环境蕨类植物能生长但是植株都比较弱小；在照度1500lux的环境蕨类植物能较好的生长，说明蕨类植物的耐阴性比较强；在照度3000lux的环境蕨类植物长势最好，这是人工种植最理想的环境；在照度20000lux的环境太强的光照对蕨类植物生长造成了困扰。

【结论】研究结果给蕨类植物在人工培育和城市绿化提供了参考。 

【 Objective 】 To study the effects of sunshine on the growth of 4 ferns in Baoshi Mountain. 【 Methods 】 Four common ferns in Baoshi Mountain were used as observation materials. Field observation method was used to investigate the influence of light on the growth of four species of ferns under four illumination gradients [results] ferns could grow but plants were weak in the environment of 500lux of illumination. Ferns can grow better in the environment of 1500lux, indicating that ferns have strong negative tolerance. Ferns grow best in 3000lux environment, which is the most ideal environment for artificial cultivation; Too strong light in 20000lux environment caused trouble to the growth of ferns. 【 Conclusion 】 The results of this study provide a reference for artificial cultivation of ferns and urban greening.
