樱桃的特性及其早结果早丰产技术的研究

Cherry's Characters and Early Bearing and High Yield Culture Techniques

在良好的栽培条件下,樱桃发枝多,树冠形成快。早期产量与干径有密切关系。幼树短果枝数量多,座果率高;长果枝是主要结果枝,其产量占全树总产量的50.69％.试验园采用选择园地、土壤,挖大穴施足底肥,选用优良品种,搭配授粉树,合理整枝修剪和加强土肥管理等综合措施。栽后第2年平均产量为25.0kg/667m^2,第3年单株平均产量7.7kg,最高为22.5kg,平均产量为275.7kg/667m^2,达到早果丰产目的。

Under the good cultivated conditions,cherry tree is very fast-growing, and the canopy forms quickly. There is a close relationship between the fruit yield and the diameter in the early development stage. For the young tree, there are a lot of spurs on which the fruiting rate is high, and the yield of the long fruit shoots occupies 50.69 per cent of the total output of the tree. Some techniques were made in this study. They are: selecting the soil and location of plots or fields, digging big cavers to apply abundant fertilizer, employing high-quality varieties, disposing pollenizers, giving a reasonable form pruning and strengthening soil-fertilizer management etc. The 2nd year after the tree planting, the average yield of the fruit was 25.0 kg/667 m2. In the 3rd year, the average yield of a single tree was 7.7kg, the highest 22.5 kg, and the average yield of the fruit reached up to 275.7 kg/667 m2. Thus the purpose of early bearing and high yield was achieved.
