| 欧李作为我国特有的野生植物资源，以其突出的抗性，较高的食用价值、观赏价值、生态价值和经济价值备受关注。本研究针对榆林地区干旱少雨、土壤瘠薄等实际问题，引入“农大5号”欧李和“京欧1号”欧李，通过对不同栽植密度下欧李植株存活率、株高、冠幅、分枝数、叶片长度、叶片宽度的调查，观测欧李在榆林地区种植的表现情况，为促进欧李产业的健康发展提供技术支撑。结果表明（1）欧李在榆林地区可越冬存活，平茬后可萌发出当年生新枝6-8枝。“京欧1号”欧李在株、行距为0.5m×0.7m时存活率最高，为54.76% “农大5号”欧李在株、行距为0.8m×1 m时存活率最高，为82.14%。（2）“农大5号”欧李的株型（株高40.74-53.46cm，冠幅40.15-46.19cm）与“京欧1号”欧李的株型（株高26.67-35.22cm，冠幅26.80-30.67cm）相比较大，且种植密度越大，“农大5号”欧李的株高越高。种植密度对2个欧李品种叶片的长度、宽度、当年新生枝条数量无显著影响。（3）“京欧1号”欧李叶片宽度及长宽比显著高于“农大5号”欧李的叶片。“京欧1号”欧李叶片长度与宽度呈现等速生长。 |
| 英文摘要: |
| Cerasus humilis a, a wild plant with high edible, ornamental, economic and ecological values, is mainly found in China. Yulin is located in the arid and semi-arid area of northwest China, where the climate is arid and the land is barren. To explore whether Cerasus humilis can be grown in Yulin, the study introduced two varieties of Cerasus humilis to Yulin such as the " Nongda No. 5" and the " Jingou no.1 ". Growth features of the plant, including survival rate, plant height, crown width, branch number, leaf length, leaf width, was investigated in different planting densities. The results showed that (1) Cerasus humilis could survive over winter in Yulin region and sprouted 6-8 new branches after reaped. The survival rate of "Jingou no.1" was 54.76% when the plant and row spacing were 0.5m×0.7m, and that of "Nongda No.5" was 82.14% when the plant and row spacing were 0.8m×1 m. (2) The plant type of "Nongda No. 5" (height 40.74-53.46cm, crown width 40.15-46.19cm) was larger than that of "Jingou No.1" (height 26.67-35.22cm, crown width 26.80-30.67cm), and the plant height of "Nongda No. 5" was higher with higher planting density. The planting density had no significant effect on the length and width of leaves and the number of new branches. (3) The leaf width and length-width ratio of "Jingou 1" were significantly higher than that of "Nongda 5". The leaf length and width of "Jingou no. 1" prunus plumage grew at the same rate. "Nongda no. 5" Prunus plumage plants spend more energy on leaf length growth. |
