从南非和以色列引进伯尔硬胡桃果核,在云南省文山壮族苗族自治州进行育苗移栽试验。结果表明:伯尔硬胡桃果核经过机械方法打破休眠后,3月中旬播种,15~20天出苗,11月中旬南非野生种源伯尔硬胡桃平均苗高145.7 cm、茎粗2.0 cm;以色列栽培种源伯尔硬胡桃平均苗高116.1 cm、茎粗1.6 cm;南非野生种源伯尔硬胡桃3年生平均树高250.2 cm、茎粗4.2 cm,以色列栽培种源伯尔硬胡桃3年生平均树高213.6 cm、茎粗3.7 cm;苗期或者移栽后,南非野生种源伯尔硬胡桃比以色列栽培种源伯尔硬胡桃生长快,株高及茎粗差异极显著。伯尔硬胡桃引种到云南省文山州种植,在干热河谷地区,表现出生长迅速、抗病虫能力强、适应当地气候环境条件。
Introduced Burr hard nutcracker from South Africa and Israel and conducted seedling transplanting experiments in Wenshan Zhuang and Miao Autonomous Prefecture in Yunnan Province. The results showed that the seeds of Burr hard nut were disrupted by mechanical methods and sowed in mid March and 15-20 days after emergence. In mid November, the average seedling weight and height of Burdock walnut in South Africa were 145.7 cm and 2.0 cm respectively. The average seedling height was 116.1 cm and the stem diameter was 1.6 cm. The 3-year average tree height and the stem diameter were 420.2 cm and 3 cm, respectively. The tree height was 213.6 cm and the stem diameter was 3.7 cm. After the seedling stage or transplanting, the South African wild germinating Barn hardnuts grew faster than the Israeli cultivated Berkshire nuts, with significant differences in plant height and stem diameter. Introduced to Wenshan Prefecture of Yunnan Province, Burr hardy walnut was planted in Wanshan Prefecture of Yunnan Province. It showed rapid growth, strong resistance to pests and diseases, and adaptability to local climatic and environmental conditions.
