摘要
为了探索潍坊地区‘大和长芋’山药的种植技术,研究了不同的播种日期和种植密度对‘大和长芋’产量的影响。采用随机区组排列,播期设置4月21日、4月27日、5月3日、5月9日、5月15日5个水平,667 m^2种植密度设置4 002、5 336、6 667、8 004、9 338株共5个水平。结果表明：播期、种植密度对‘大和长芋’的产量均有显著影响。在播期的5个处理中,‘大和长芋’产量最高的是4月21日、4月27日;在种植密度的5个处理中,667 m^2种植8 004、9338株的产量最高。建议在潍坊地区‘大和长芋’山药最适宜播期为4月下旬,667 m^2种植密度控制在8 004-9 338株。
In order to provide scientific basis for planting technology of‘Daiwa Long＇yams in the Weifang,the effects of different seeding time and planting density on yield of‘Daiwa Long＇yams were studied. Randomized block arrangement was used,sowing date was setted five levels（April 21,April 27,May 3,May 9 and May 15） and planting density on 667 m^2 was also setted five levels（4 002,5 336,6 667,8 004,9 338 plants）. The results showed that the yield of‘Daiwa Long＇yams was significantly affected by sowing date and planting density. When planting in April 21 and April 27,planting density on667 m^2 were 8 004,9 338 plants,the yield was the highest respectively. In Weifang,the most suitable seeding time of‘Daiwa Long＇yams was in late April,the best planting density on 667 m^2 was between 8 004 to 9 338 plants.
