铁丰18号大豆育成于辽宁铁岭,不但在辽宁已成为主栽品种,而且从1974年以来经全国各地广泛试种(北京、河北、甘肃、宁夏、新疆、四川)也都表现增产,具有广泛的适应性,较高的经济效益和较强的抗病能力。近几年,又在科研部门及各地区试种,系统观察了在不同栽培环境下的生态表现,为研究铁丰18号在全国各地的生态规律提供了丰富资料。本文根据这些试验数据,研究了铁丰18号在全国各地不同地理纬度和不同海拔高度上栽培的生态模式,为铁丰18号易地种植提供依据。
Tiefeng 18 soybean was bred in Tieling, Liaoning Province. It has become a major cultivated species in Liaoning Province and has also been extensively planted (Beijing, Hebei, Gansu, Ningxia, Xinjiang and Sichuan) since 1974, Adaptability, high economic efficiency and strong resistance to disease. In recent years, scientific research departments and various regions have also been experimentally tried to systematically observe the ecological performance under different cultivation environments, providing abundant information for studying the ecological rules of Tiefeng No. 18 throughout the country. Based on these experimental data, this paper studied the ecological model of Tiefeng 18 cultivated at different geographical latitudes and altitudes across the country, and provided the basis for the ex situ cultivation of Tiefeng 18.
