农业科学技术是发展农业生产和提高产量及其经济效益的关键因素.近几年来,随着农村商品化生产进一步发展,经济效益问题已被提到很高的位置,因此,就要求农业科研要面向经济,讲究经济效益,使能收到少投入、多产出的技术经济效果.近年来我省的杂交稻在闽西北的建阳、三明等地区种植面积大而且稳定,而在南部地区种植面积却有所下降,其原因虽是多方面的,其中与一些地区认为杂交稻增产幅度不大,多花工本,增产不增收,经济效益差有关.为了促进杂交稻进一步发展,我们对杂交稻的增产及其经济效果进行了调查研究和分析,以期探索其增产和经济效益的潜力.
Agricultural science and technology are the key factors for developing agricultural production and increasing yield and economic benefits.In recent years, with the further development of commercial production in rural areas, the economic benefits have been raised to a very high level, and therefore, agricultural research Oriented economy, pay attention to economic benefits, enabling to receive less input, more output of technical and economic effects.In recent years, hybrid rice in the province of Jianyang, Sanming and other areas in northwestern China planted large and stable, and planted in the southern region Area has declined, although its causes are many, including some areas that increase yield of hybrid rice is not big, spend more, increase production does not increase income, poor economic benefits.To promote the further development of hybrid rice, hybrid rice The increase of production and its economic effects were investigated and analyzed in order to explore its potential for increasing production and economic benefits.
