河北省张家口坝下地区是春谷重点产区,其河川区生产条件优厚,土质肥沃,常因倒伏多秕谷减产而影响春谷发展。我们于1975—1981年研究了春谷高产栽培技术,亩产逐年提高并基本稳定在1,000—1,100斤。总结了亩产千斤春谷的生理指标和高产技术,经生产鉴定,证明有显著增产效果和经济效益。 Zhangjiakou area under the dam in Hebei Province is the key producing areas of Spring Valley, its favorable production conditions in the River District, fertile soil, often due to the lodging of more Hutui production and affect the development of Spring Valley. We studied Spring Valley high-yielding cultivation techniques from 1975 to 1981, and the yield per mu was gradually increased and basically stabilized at 1,000-1,100 kg. Summarized the physiological indicators of high yield per mu yield Spring Valley and high-yielding technology, identified by the production, proved a significant increase in production efficiency and economic benefits.
