辽宁是我国栗树栽培的北缘,现有栗树1500万株。但是种类混杂,劣多优少,产量低,结果晚,品质差。为尽快解决这个问题,引种外地优良品种是节省时间、易见成效的措施。为此,我们于1972年从山东引入处署红(原产浙江,是宜兴、长兴、广德等地广泛栽培的早熟品种,1964年引入山东)。几年来,经过各地试栽,表现适应性较强,早实丰产,是个比较好的品种。现将引种结果报告如下。一、品种主要特征处署红树姿开张,树冠半圆形,1年生枝灰绿色,阳面红褐色,枝软易下垂(为本品种的突出特征)。叶片大,光泽不明显。刺苞短 Liaoning is the northern edge of Chinese chestnut cultivation, the existing 15 million chestnut trees. However, the types of mixed, poor and more excellent, low yield, the results of late, poor quality. As soon as possible to solve this problem, the introduction of foreign fine varieties is time-saving, easy to see results. To this end, we introduced the Department of Red Depot from Shandong in 1972 (native to Zhejiang, Yixing, Changxing, Guangde and other widely cultivated precocious varieties, introduced in 1964 in Shandong). Over the past few years, after all over the trial planting, performance adaptability, early fruiting, is a better breed. The introduction of the results reported below. First, the main characteristics of the species Deployed mangrove position opened, the crown semicircular, 1 year old branches gray-green, reddish brown, soft branches easy to sag (the outstanding features of this species).
