将农业科学技术“物化”成产品以及实现作物生产轻简化和机械化是破解农技推广“最后一公里”难题的重要手段。以重庆市江津区的主要作物水稻作为研究对象,对水稻配方肥及其与机插秧技术的集成应用效果进行综合评价。结果表明:“配方肥+机插秧”农户和“配方肥”农户分别比对照户增产28.4%和22.6%、增收196元/亩和77元/亩,同时减少了农户施肥的不合理变异。因此,通过对测土配方施肥技术“物化”来简化技术推广,并与机插秧技术的有效结合是小农户经营条件下西南稻区实现大面积高产高效的重要抓手。
The “science and technology” of agricultural science and technology into products as well as the realization of light crop production and mechanization is the key to solving the “last mile” of agricultural technology promotion. Taking the main crop rice in Jiangjin District of Chongqing Municipality as the research object, the integrated evaluation of the application effect of rice formula fertilizer and its technology of machine-transplanting rice seedling was comprehensively evaluated. The results showed that the yield of “formula fertilizer + machine transplanting seedling” and “formula fertilizer” farmers increased by 28.4% and 22.6% respectively compared with that of the control households, with an increase of 196 yuan / mu and 77 yuan / mu, respectively, while reducing the farmers’ fertilization Reasonable variation. Therefore, simplifying the technology popularization through the technology of soil testing and formula fertilization “physicochemical ” and the effective combination with machine transplanting techniques is an important starting point to realize large area, high yield and high efficiency in the southwest rice area under the operating conditions of small farmers.
