为了探索发挥我省高寒阴湿地区土壤基础肥力较好,水分较多的优势,研究克服在温度较低条件下主要粮食作物丰产栽培技术及其在本区的效应和实用价值,为农业生产提供丰产栽培技术组合,1989～1990年在康乐县八松乡开展了主要粮食作物丰产栽培技术效应的研究工作。一、试验地基本情况试验设在康乐县八松乡,海拔2300米,年平均气温4.9℃,≥0℃积温2461.7℃,≥10℃积温1469.9℃,无霜期120天,年降水量650毫米。试验地土壤为黑土,而且平整肥力均匀。历年春小麦试验前茬为蚕豆,蚕豆、马铃薯试验前茬为小麦。据播前试验
In order to explore the advantages of better soil base fertility and more water in the cold and humid areas of our province, this paper studied the effects and practical value of high-yielding cultivation techniques of main grain crops under low temperature and their effects in the area and provided suggestions for agricultural production High-yielding cultivation techniques, from 1989 to 1990 in Balesong Township, Kangle County, carried out research on the technical effects of high-yield cultivation of major grain crops. First, the basic conditions of the experiment The test is located in Balesong Township, Kangle County, with an altitude of 2300 meters and an average annual temperature of 4.9 ℃. The accumulated temperature of ≥0 ℃ is 2461.7 ℃, the accumulated temperature of ≥10 ℃ is 1469.9 ℃, the frost-free period is 120 days and the annual rainfall is 650 mm. Soil test for the black soil, and even the formation of fertility. Past wheat spring wheat test for the Vicia faba, broad beans, potato test before the wheat crop. According to pre-broadcast test
