龙陵县滇重楼林下栽培试验

Understory Paridis polyphylla Cultivation Test in Longling

对滇重楼进行林下仿野生栽培实验。结果表明,潮湿且肥沃疏松的砂壤土和壤土、遮荫度为60%～70%的阔叶树林下是重楼丰产的基础条件;种子繁殖时,对种子采用高锰酸钾、赤霉素浸种或草木灰拌种处理,能保证第一年有较高的出芽率;根茎繁殖时,选择种苗根茎为10～20 g的可以降低成本并提高重楼产量;以农家肥和沼液为主,复合肥和各种微量元素肥料为辅的科学合理施肥方法能保证重楼有较高的产量。

Understory imitated wild cultivation experiment of Paridis polyphylla was carried out. The re- sults showed that the moist, fertile and loose sandy loam and broadleaf understory with shade degrees of 60% to 70% were the basic condition for high yield of Paridis polyphylla. During seed propagation peri- od, soaking seeds with permanganate, gibberellin or dressing seeds with plant ash, could ensure high budding rate in the first year; during rhizome reproduction period, selecting seedling rhizomes of 10 -20g could reduce costs and increase yield of Paridis polyphylla. Taking scientific and rational fertilization method of farmyard manure and biogas slurry as priority, fertilizer and various trace elements fertilizer as supplement could guarantee a higher yield of Paridis polyphylla.
