试验于1981年开始进行,供试品种为荸荠种杨梅,试材为一年生嫁接苗,进行4种不同栽培措施处理。通过8年试验表明,对杨梅幼树采取挖大栽植穴,增施基肥,之后每年进行一二次适量施肥,及时扩大栽植穴,同时采用三主枝为主的分层形树形,结合夏季修剪拉大主枝与辅养枝角度等措施,防止树冠上强下弱,使幼树栽植第3年结果株率即达52.0％,之后产量逐年上升,第5年平均株产达17.18kg,第8年高达37.88kg,栽植后累计平均株产分别比其它两个处理和对照树提高71.1％、4.1倍和88.6倍,经济效益明显;而生产上常用的栽培方法(即对照),幼树栽植后第7年结果株率才达到36.7％,第8年平均株产仅0.97kg。
The experiment began in 1981, the test varieties were water chestnut Bayberry, the test material was annual grafted seedlings, carried out 4 different cultivation measures. After eight years of experiments, it was shown that the arborvitae seedlings were dug and planted with planting holes to increase the base fertilizer, and once or twice a year, fertilization was carried out to expand the planting hole in time. At the same time, the three-branch- Pruning the main branch and the pruning branch pruning angle and other measures to prevent the crown on the strong weak, the young tree planting results in the third year rate of 52.0% of the plant, after the production increased year by year, the average annual production of the fifth year up to 17.18kg, In the 8th year, it reached 37.88kg, the accumulated average yield after planting was 71.1%, 4.1 times and 88.6 times higher than that of the other two treatments and control trees, respectively. The economic benefits were obvious. The common cultivation methods (ie, control) In the 7th year after planting, the result rate was 36.7%, and the average yield in the 8th year was only 0.97kg.
