三只羊岩溶峰丛洼地桃树优质高产栽培技术研究

在广西三只羊岩溶峰丛洼地进行幼龄期桃树作物套种、施肥以及疏果等栽培技术的对比试验。结果表明,套种黄豆能明显促进桃树基茎和主枝直径的增长,套种玉米则抑制桃树基茎和主枝直径的增长;混施猪粪水和磷肥的桃树其果实品质明显优于混施羊粪和磷肥以及牛粪和磷肥的桃树的果实;同时,中等疏果强度,即保留枝条上桃果间距14~18cm,可获最大种植效益,桃果重量增加50.3%,桃树的产值提高52.9%。

Study on high yield of quality fruits of peach growing in karst peak-cluster depression area

The experiments including interplanting with soybean and maize, fertilizing with waste of pigs,goats and scalpers,fruit thinning at different scales were carried out in a karst peak-cluster depression area. The resuits revealed that trees interplanted with soybean developed better with bigger stems and bigger branches than that of non-interplanted trees, but trees interplanted with maize developed not well with smaller stems and smaller branches than non-interplanted trees ; trees fed with waste of pigs could more effectively bear high quality fruits than those fed with waste of goats or cows. As for prunning, the results showed that medium strength pruning,which kept the fruits 14-18 cm apart on the branch, obtained the highest economic benefit.
