Abstract
This experiment was carried out to investigate the effect of seeding date on the growth and yield of Cynanchum wilfordii. Hemsley emergence date was May 16 with seeding on March 20 and was June 4 with seeding on April 30, and required days to emergence was shortened as seeding date was delayed. Vine length was longer about 5cm with seeding on March 30 than that of seeding on march 20 and no. of leaves was small about 5 to 16 as seeding date was delayed. Root length was longer about 0. 9cm to 1. 8cm as seeding date was delayed than that of seeding on March 20, but no. of roots had no differences among seeding dates. Yield of root was more increased 18% with seeding on March 30, 10% with seeding on April 10 and April 20 than 207kg/10a with seeding on March 20. As the results of regression analysis, the optimum seeding date of Cynanchum wilfordii Hemsley was considered April 6 in plain area of central inland.
중부(中部) 내륙지방(內陸地方)에서 백하수오(白何首烏)의 파종적기(播種適期)를 구명(究明)하고자 충북지방재래종(忠北地方在來種)을 공시(供試)하여 10a당(當) 퇴비(堆肥) 1,000kg, N - P - K=8 - 4 - 4kg을 전량(全量) 기비(基肥)로 시용(施用)하고 파종기(播種期)는 3월(月) 20일(日)부터 10일(日) 간격으로 4월(月) 30일(日)까지 5회(回)에 걸쳐 파종(播種)하여 시험(試驗)을 하였던 결과(結果)를 요약(要約)하면 다음과 같다. 1. 출아(出芽)는 3월(月) 20일(日) 파종시(播種時) 5월(月) 16일(日)로 57일(日)이 소요(所要)되었으나 4월(月) 30일(日) 파종(播種)은 6월(月) 35일(日) 소요(所要)되어 파종(播種)이 늦어질수록 출아(出芽) 일수(日數)가 단축(短縮)되었다. 2. 만장(蔓長)은 3월(月) 20일(日) 파종(播種) 236cm에 비(比)하여 3월(月) 30일(日) 파종(播種)은 5cm 길었으나 엽수(葉數)는 3월(月) 20일(日)의 79매(枚)보다 파종(播種)이 늦어질수록
