구범자(枸杞子)의 주당(株當) 적정(適正) 줄기수와 번식방법(繁殖方法)을 구명(究明)하고자, 1993~1994년(年)까지 시험(試驗)을 실시(實施)하여 얻은 결과(結果)를 요약(要約)하면 다음과 같다. 1 구기자(拘杞子) 번식방법(繁殖方法)은 종자번식(種子繁殖)에 비해 개화기(開化期)가 15일 빠르고, 건과수량(乾果收量)이 91kg/10a로 30%가 증수(增收)된 지삽(枝揷) 20cm가 가장 좋았다. 2 삽수 굵기는 건과수량(乾果收量)이 227kg/10a로 방임구(放任區)에 비해 28% 증수(增收)된 0.9cm가 좋았다. 3. 주당 적정(適定) 줄기수는 줄기수 5본에서 생육(生育)이 가장 좋았고 100과중도 13.4g으로 가장 무거웠다. 4. 주당(株當) 착과수는 864개로 줄기수 5본에서 증가(增加)되었고 건과수량(乾果收量)도 줄기수 5본에서 104kg/10a로 방임구(放任區)에 비해 16% 증수(增收)되었다.
Experiments were conducted to investigate the proper stem number and the propagation method of Lycium Chinense Mill. from 1993 to 1994.The results obtained were summerized as follows. The most effective propagation method was stem cutting 20cm in which flowering time was 15days earlier and dry fruit weight was 30 percent heavier(91kg/10a) than in seed propagation. The optimal diameter of cutting was 0.9cm of which dry fruit weight was 227kg/10a and 28 percent heavier compared with that of 0.5cm. stem number 5 had the best top growth and the heaviest 100 fruit weight as 13.4g. Fruit number per plant was increased as 864 in stem number 5. Dry fruit yield of stem number 5 was 104kg/10a and 16 percent increased compared with that of control.
