椪柑树势直立,树冠直径偏小,枝条细弱,如何使它在偏酸性、肥力中等的山地速生,形成早投产、丰产的强壮树冠,这是椪柑栽培的重要技术环节。为此,我们对30株椪柑进行了速生栽培试验。在幼苗定植三年后,树冠平均高度已达2.1米左右,直径达1.3米左右,预计今年可每株结果10～15公斤,比对照的结果提早二年,树冠高度、直径增一倍多。其具体做法是: 1.幼树薄肥勤施。一至三年生的幼树,在二月下旬至八月上、中旬,每月施一次稀薄的腐熟人粪尿,在春、夏、秋梢萌发前,
Squash tree erect, crown diameter is small, thin branches, how to make it in the acidic, fertility and moderate mountain fast-growing, the formation of early production, high yield of strong crown, which is an important technical aspect of Citrus cultivation. For this reason, we carried out the fast-growing experiment on 30 Citrus grandis. Three years after the seedlings are planted, the average height of the canopy has reached about 2.1 meters and the diameter is about 1.3 meters. It is estimated that 10-15 kilograms per plant will be produced this year, two years earlier than the control. The height and diameter of the canopy more than doubled. The specific practices are: 1. Young trees thin fertilizer Qin Shi. Young saplings of one to three years old will apply a thin amount of decomposed human excrement once a month in late February to mid August and mid August. Before spring, summer or autumn shoots germinate,
