不同林下七叶一枝花栽培技术研究

为了减少七叶一枝花野生资源的消耗，满足市场需求，节约生产成本，提高林地的利用率，增加林农收入，保护生态环境，选择常绿林地（杉木林地）、阔叶林地（核桃林地）与灌木林地（金银花林地）3种类型的林地，采用湖南本地洪江八面山生产的七叶一枝花种子和根茎切块2种繁殖材料，开展了林下育苗和栽培技术研究。结果表明：选择繁殖材料时，应采用种子繁殖，可减少野生资源的消耗，大量提供种苗，有利于规模化种植；不同繁殖材料采用育苗移栽和直播直栽林下规模种植时，宜采用直播直栽，可节约生产成本，提早投产；3种不同类型林地种植时宜选择阔叶林地，符合七叶一枝花的生态习性和生长发育规律，获得更好的经济效益。

Study on Different Understory Cultivation Techniques of Paris polyphylla Smith

The paper aims to reduce consumption of wild resources of Parispoly phylla Smith, satisfy the market demand, save the production cost, improve the utilization rate of forest land, increase the income of forest, and protect the ecological environment. The author selected three types of forest land, the evergreen forest land (China fir forest), deciduous forest land (nut forest) and shrub land (honey suckle forest.), and used two kinds of seeds and roots slices materials of Paris polyphylla Smith which were produced in Bamian Mountain, Hunan, to carry out the study on forests seedling and cultivation techniques. The results showed that: when using different propagation materials, seed propagation should be adopted, which could reduce the consumption of wild resources and provide a large number of seedlings, this technique was beneficial to largescale planting. When using different breeding materials with seedling transplanting and live straight planting in large-scale understory cultivation, live straight planting was appropriate, it could save the production cost and put into production early. Among the 3 different types of forest land cultivation, the best choice was broadleaved forest land, it could achieve better economic benefit because of conforming with Paris polyphylla Smith ecological habit and its growth and development rule.
