山楂的适应能力较强,在我省各地都有分布。近年来在我省承德等地区发展很快,大量植株开始进入结果期,但平均产量甚低,因之,研究总结山楂的丰产栽培技术是当务之急。从1979年开始,我们用昌黎果树研究所和我校6—8年生的山楂树共20株进行了生物学特性观察,为制订正确的栽培措施提供依据。本文报导了山楂的枝叶生长及开花结果习性的观察结果,以供参考。
Hawthorn ability to adapt to strong, all over the province have distribution. In recent years, Chengde and other areas in our province developed rapidly, a large number of plants began to enter the fruiting period, but the average yield is very low, therefore, the study concluded that hawthorn high yield cultivation techniques is a top priority. Since 1979, we have used 20 plants of Changli Fruit Research Institute and Hawthorn Trees of 6-8 years old in our school to observe the biological characteristics and provide the basis for formulating correct cultivation measures. This article reports the results of the observation of the hawthorn’s foliage growth and flowering habits, for reference.
