目的缩短云南多叶蓼种子萌发时间，提高种子出苗率，最终建立实用的多叶蓼种子播种方法。方法研究温度、播种时间、覆盖土壤深度、地膜等因素对云南多叶松种子出苗的影响。结果18-20℃低温处理3-4个月后，在0-10℃低温处理2-4个月后，可于4月出籽。种子出苗的最佳播种期为4月前。土壤深度宜在1 cm左右。在苗床上覆盖黑色塑料薄膜是提高出苗率的较好方法。结论以上结果为云南多叶松的育苗技术提供了依据。
OBJECTIVE To shorten the duration of seed germinating, improve seed emergence and eventurally to establish a practical method for seeding of Paris polyphylla var. yunnanensis seed. METHOD To study the effect of some factors (temperature, sowing time, covering-soil depth, plastic film ) on seed emergence of P. polyphylla var. yunnanensis. RESULT The most suitable temperature for embryonic post-maturity and seed germinating is 18-20 degrees C. Paris seed could emerge in April when it was transfer to a low temperature 0-10 degrees C for 2-4 months after being treated under 18-20 degrees C for 3-4 months. For seed emergence, the best sowing time was before April. The suitable soil depth was about 1 cm. It is a better way to cover the seedling bed with black plastic film for improving the emergence percentage. CONCLUSION Above results provide seedling techniques of P. polyphylla var. yunnanensis.
