近几年我所在甜菜种肥分层机播与机械覆膜穴播技术上进行了多年的试验、示范和推广工作,对甜菜确保全苗起了很大作用。但在一些技术新引进区使用该项技术时还存在一些问题,为此,现将有关技术关键再次介绍,供作参考,避免生产中造成不应有的损失。 In recent years, we have beet seed layering and mechanical laminating machine broadcast technology for many years on the pilot, demonstration and promotion of sugar beet to play a significant role in the whole seedlings. However, there are still some problems in using this technology in some new technology introduction areas. For this reason, the key technical issues are introduced again for reference and avoid undue losses in production.
