湖南超级杂交稻“种三产四”丰产工程经济评价初探（英文）

Economic Evaluation on "Planting Three to Produce Four" High-yielding Project of Super Hybrid-rice in Hunan

该文在收集湖南6县（市、区）2007~2014年相关资料并于2014年实地调研186户农户的基础上,开展了超级杂交稻＂种三产四＂丰产工程经济评价。结果表明,湖南＂种三产四＂5种种植模式增产增收效果明显,其中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,降低费用的重点是减少机械费和请工费。

The research conducted investigation and survey on 186 farm households in 2014 and carried out economic evaluation on ＂planting three to produce four＂ highyielding project of super hybrid rice. The results showed that the project of ＂planting three to produce four＂ performed significantly in terms of increasing yields and incomes. For example, per unit area yield of one-season late hybrid rice and middleseason hybrid rice proved the highest, and net income from middle-season rice in Longhui was the highest. It is obvious that to increase per unit yield is key for improving net incomes and to reduce machine fees and worker fees is crucial for decreasing fees.
