欧李是我区的一种野生果树,人工栽培尚属首例。本文以人工栽培的3年生欧李为试材,调查了株丛内不同类型枝条的生长量、粗度、成花数、座果率和单枝产量。结果表明:欧李不同类型枝条生长结果差异很大,以基生枝生长结果最佳,是欧李株丛的主要结果枝。提出了欧李的丰产形态指标为。欧李以带状栽植的方式为好,每带3行,带内密度1.0×1.5m,带间距离2.0m;每株丛结果枝数15个,其中基生枝11～12个,2年生枝3～4个;基生枝粗度0.40cm 以上,1级枝粗度0.25cm 以上;每年选留和培养新的基生枝12～15个作为更新枝。
Ou Li is a wild fruit tree in our district, and is the first case of artificial cultivation. In this paper, cultivated three-year-old European plum was used as test material to investigate the growth, coarseness, flower number, fruit set rate and single-branch yield of different types of branches in the plant. The results showed that the results of the growth of the different types of branches are very different, with the best result of the primary branch growth, which is the main branch of the European branch. Proposed the high yield of European plum form index. Oolong is planted in tapes as well, with 3 lines in each zone. The in-band density is 1.0 × 1.5m and the distance between bands is 2.0m. The number of branches per plant is 15, of which 11 to 12 are primary branches and 2 years are branches 3 to 4; basal branches of 0.40cm or more in diameter, a branch of the thickness of more than 0.25cm; annual selection and training of new basal branches 12 to 15 as a replacement branch.
