摘  要：
在实地调研湖南省6县(市、区)186户稻农的基础上,采用通径分析方法对超级杂交稻"种三产四"丰产工程增产增收效果进行了评价。结果表明,湖南省"种三产四"的5种种植模式增产增收效果明显,其中以一季晚超和中超模式单产增幅最大,隆回中稻的纯收入水平最高;增加纯收入的主攻方向是提高单产和降低费用,降低费用的重点核心区是减少机械费和肥料费,非核心区则是减少雇工费和机械费。

摘  要：
Based on a survey of 186 rice farmers in 6 counties(districts, cities) of Hunan, the study evaluated the effects of super hybrid rice "Planting Three to Produce Four" high yielding project on increasing yield and income. The results showed that five planting modes of Hunan "Planting Three to Produce Four" increased the yield and income significantly, in which yields of single-season super late rice mode and super medium rice mode increased the most, and the net income in Longhui medium rice was of the highest level. The main direction to increase the net income is to improve yields and reduce costs. The core area of reducing the cost is to reduce machinery costs and fertilizer costs, while the non-core area is to reduce labor costs and machinery costs.
