我国从日本引进水稻工厂化育秧技术以来,经过试验示范已开始大面积推广。水稻工厂育苗工艺流程中,脱芒机械加工稻种作为一道工序是必不可少的。但是,从开始引进试验到今天的大面积推广,国内无论是有关科研单位还是农业生产管理部门普遍忽视且不安排脱芒机械加工工序,绝大部分工厂化育秧生产点取消了这一生产环节。 Since the introduction of rice plant breeding technology from Japan, our country has started large-scale popularization after trial and demonstration. Rice plant nursery process, pruning machined rice as a process is essential. However, from the beginning of the introduction of tests to the large-scale promotion today, no matter whether the relevant scientific research units or agricultural production management departments generally ignored and did not arrange the process of removing mango machining, the vast majority of factory production sites for raising seedlings have canceled this production link.
