浩浩巴引种试验研究

INTRODUCTION TRIAL OF JOJOBA(Simmondsia chinensis Link)

从1984年超,在湖南进行浩浩巴多点引种裁培试验。结果表明,在江永试验点上,植株能够正常生长发育。5年生浩浩巴已连续3年开花结果,产量逐年增加,并培育出了第2代实生植株。种子的含油率达到54.3%,为国内外的中上水平。引种获得成功,可适度推广发展。衡阳以北地区。因零下低温频繁而造成冻害,影响到浩浩巴的正常生长发育,不宜盲目进行引种。实践证明,年均温、1月均温,活动积温、极端低温和光照条件,是浩浩巴引种栽培成败的主要限制因子。

Introduction and cultivation trials of the jojoba were conducted on several sites of Hunan from 1984. The results indicate as follows: On the Jiangyong trial site, plant can grow and develop normally. The 5-yearold plants blossom and bear fruit in 3 consecutive years, increasing yield year after year. The seedling plant of the second generation has been raised. The seed oil content accounts for 54.3%, attaining the upper-middle level at home and abroad. Therefore, the introduction, which may be extended moderately, is successful. To the north of Hengyang, however, the jojoba cannot be introduced blindly because it does not grow and develop normally owing to the freeze injury caused by the frequent low temperatures (below 0℃). Facts have proved that annual mean temperature, January mean temperature, extreme low temperature and the sunlight condition are the main limiting factors affecting the introduction of the joioba.
