近年来,甜菜的种植已越过黄河,正在南方各省发展。与此同时,各地本着自力更生的精神,积极发展了种子生产。根据1971年在山东省茌平县陶桥大队的试验和对若干生产队的调查情况,我们谈谈新区甜菜采种的有关技术。一、母根贮藏甜菜是二年生作物,生活的第一年主要是营养生长,第二年主要是生殖生长,完成生殖生长必须通过春化和光照两个阶段。春化阶段的关键是温度,即甜菜母根要在0—3℃的低温和一定的湿度、空气条件下,贮藏一个月左右,方能通过春
In recent years, sugar beet cultivation has crossed the Yellow River and is under development in the southern provinces. At the same time, all localities actively developed seed production in the spirit of self-reliance. Based on the tests conducted by the Taoqiao Brigade in Chiping County, Shandong Province, in 1971, and the investigation of several production teams, we talked about the technology for planting beet in the New District. First, the storage of sugar beet roots is a biennial crop, the first year of life is mainly vegetative growth, the second year is mainly reproductive growth, reproductive growth to complete the two stages of vernalization and light. The key of the vernalization stage is the temperature, that is, the beet root must be stored at a low temperature of 0-3 ° C and a certain humidity and air for a month or so before it can pass the spring
