太行山区柿树资源丰富,栽培历史悠久,是山区群众一项重要经济收入。但是,由于栽培管理粗放,产量低而不稳。我县有结果树12万株,1982年列为河北省太行山开发研究项目,四年来,通过综合技术管理,取得了明显的增产效果。现将试验研究情况介绍如下: 一、试验区概况及方法 试验基地上庄在磁县山区贾壁乡,位于北纬36°29′,东经114°4′22″,海拨400米。年平均气温12.9℃,最高气温41.4℃,最低气温-19.4℃。无霜期197天,全年日照量2774.34小时,常年降雨量507.67毫米,主要分布在七、八月份。土质为轻壤和中壤,PH值7.5。
Taihang Mountain persimmon resource-rich, cultivation has a long history, is an important mountainous area of economic income. However, due to extensive cultivation and management, the output is low and unstable. There are 120,000 fruit trees in our county. In 1982, it was listed as a research and development project of Taihang Mountain in Hebei Province. In the past four years, it has achieved remarkable yield increase through integrated technical management. The experimental study is introduced as follows: I. Overview and Methods of the Experimental Zone Shangzhuang is located in Jiabi, a mountainous area in Cixian, located at 36 ° 29 ’north latitude and 114 ° 4’22 east longitude with an altitude of 400 meters and an average annual temperature of 12.9 ℃, the highest temperature of 41.4 ℃, the lowest temperature of -19.4 ℃. Frost-free period of 197 days, the annual amount of 2774.34 hours of sunshine, perennial rainfall of 507.67 mm, mainly in July and August. Soil is light and medium soil pH 7.5.
