摘要
目前广西水稻免(少)耕生产一些关键环节还处于人工为主的状态,不能适应全程机械化发展的必然趋势。为了探索该区机械化免(少)耕生产模式,本文采用实证分析的方法进行研究。结果表明,相比于传统生产模式,免(少)耕生产模式在保持水土、培肥地力、节本增效、促进生态平衡、减少水域淤积和环境污染等方面具有明显优势。广西目前存在的免耕抛秧因种植环节实现机械化的问题,并不能成为未来的主导模式。以免(少)耕机械插秧、化学灭茬(草)、秸秆还田、休闲期绿色覆盖为主要特点的技术模式可能是未来广西机械化免(少)耕生产的主导模式。广西水稻免(少)耕生产机械尚不成熟,机械研发应以小型、轻便,接地压力小不宜下陷,深泥脚田适应性好的机型为主,并以免(少)耕插秧机为研发重点。
Some key field operations of no（minimum） tillage in Guangxi were operated by manual,which could not adapt to the inevitable trend of agricultural mechanization.With the methods of empirical analysis,the paper aimed at presenting no（minimum）-tillage mode of paddy production in Guangxi.Results showed no（minimum）-tillage modes have more advantages in keeping soil,water and fertilizer,reducing cost and increasing benefit,keeping ecological balance,reducing water siltation and environmental pollution compared with traditional modes.Because it is difficult to achieve planting mechanization,no-tillage seedling-throwing will not be the dominant mode.The mechanized no（minimum）-tillage modes with the characters of no（minimum）-tillage mechanized transplanting,weeding and stubble cleaning by using herbicide,straw chopping and winter crops planting are most likely to be the dominant modes in the future.The machinery RD should be focused on the types of small-size,light-weight,having good performance of farming on the deep mud,of which the no（minimum） tillage transplanter RD is especially important.
