摘要:
为更好地了解并掌握香榧Torreyagrandis'Merrillii'林下鼠茅Vulpiamyuros的覆植技术，本文以丽水市松阳县象溪镇香榧基地为实验基地，对鼠茅的生长特性、生长规律进行观察，并对不同播种时间（2021年11月10日和2022年3月5日）和覆土处理（不覆土、扫帚扫垄面覆土、扫帚扫垄面加铁锹拍压覆土）对鼠茅种子发芽及杂草萌生数量的影响进行研究。结果表明，鼠茅生长期为3~6个月，生长所需平均温度在11~24℃；春播鼠茅样地中的杂草萌生数量比秋播的多，二者呈极显著差异（P＜0.01）；除秋播不覆土处理外，播种后，春播和秋播鼠茅种子的发芽率在50.8%~53.4%，其中春播鼠茅的发芽率比秋播的发芽率略高；鼠茅播种后的覆土措施以扫帚扫垄面覆土处理为宜。综合认为，鼠茅的播种时间以秋天（10—11月）为宜。
Abstract:
On November 9th 2021 and March 5th 2022, seeds of Vulpia myuros were sowed with different soil cover under 7-year Torreya grandis‘Merrillii’ stand in Songyang, Zhejiang province. Observation was carried out on seed germination, growth and weed growth. The result demonstrated that the growing period of V. myuros was from March to June, and the average temperature required for growth was from 11 to 24°C. There were more weeds in sample plots sowed in spring than that in autumn, with extremely evident significance (P＜0.01). Germination rate of V. myuros sowed in spring was slightly higher than in autumn. The best treatment for soil cover was natural cover with soil after sowing.
