摘要/Abstract

摘要： 通过对南北三省十县568户2001年与2007年种植的4个超级稻品种投入与产出调查,比较分析了超级稻生产的经济效益,研究了超级稻品种与生产投入对产出的经济效果影响。结果表明:在其它条件不变的情况下,"沈农606"、"协优9308"、"中浙优1号"3个品种与"II优8006"品种在面积均增加10%的情况下,2001年,前三个品种产量比II优8006品种多增加产量18.5%、17.2%、19.1%,而在2007年,产量多增加15.7%、14.3%和15.6%;在当前水平下,有机肥、钾肥用量的增加对超级稻产量增加具有显著的作用,它们和磷肥在化肥中的比例都提高10%,增加有机肥、钾肥用量比增加磷肥施用量单位面积将多增加产量6.78%和4.95%;氮肥投入水平虽较6a前有明显的改善,但其系数小于零,这说明当前超级稻生产中氮肥仍使用过量,劳动用工投入增加对超级稻产量增加影响不明显。本文对当前超级稻生产投入中应注意的几个问题进行了评述,提出了加快超级稻品种推广、生产集约化、专业化和机械化的对策与建议。

Abstract: After the investigation on the input and output of four varieties of super rice in 2001 and 2007 from 568 households which belonged to ten counties in two southward province and one northward province,this author analyzed the economic benefits of super rice,and studied the effect of input on yield of super rice.The results of the research were showed as follows: as far as the varieties of super rice were concerned,when the rice acreage increased 10 percents,the rice yields would increase 17.2 percents to 19.1 percents;When the effective content of organic fertilizer and potassium fertilizer increased 10 percents,the rice yields would increase 6.78 percents and 4.95 percents.The input of potassium fertilizer had visibly improved in past six years,but the effect of increasing labor input on the increasing yield was not distinct,and so on.So we should pay attention to the input of fertilizer.Finally,this article put forward some suggestions to extend the varieties of super rice and accelerate the intensification and specialization and mechanization of super rice production.
