摘　　要：为建立湖南省稻-油、稻-稻-油轮作制高效施肥技术体系,2007～2009年对湖南省水稻、油菜主产区开展了当地习惯施肥调查。调查表明,湖南省稻-油、稻-稻-油轮作制施肥上存在:施肥结构不合理,氮磷钾比例不协调;有机肥用量偏低,秸秆还田和有机肥施用技术需要提高;农民施肥盲目性和随意性大,缺少必要的施肥技术规程等问题。建议调整施肥结构,合理控制氮肥用量,适量增加磷钾肥用量;增加有机肥的投入,推广有机无机肥配合施用技术;加强土肥监测,尽快制定合理的施肥技术规程。To establish technique system of high efficient fertilization for Rice-Rapeseed and Double Rice-Rapeseed rotation system in Hunan Province,the fertilization convention in the maim areas of rice and rapeseed production was investigated from 2007 to 2009.The results showed that the main problems exiting in fertilization for Rice-Rapeseed and Double Rice-Rapeseed rotation system in Hunan Province are as follows： the irrational fertilization structure and uncoordinated proportion of N,P and K,low dosage of organic fertilizer and backward fertilizing technique,blindness and randomness in fertilization of farmers,lack of necessary technical regulations for fertilization,etc..Therefore,some suggestions were proposed,which are as follows： it should revise the fertilization structure,reasonably control the nitrogen fertilizer rate and increase fertilizer rate of P and K and organic fertilizer,popularize the technology of applying combination of organic fertilizer and inorganic fertilizer,strengthen monitoring of fertilizer in soil,develop reasonable technical regulations for fertilization as soon as possible,etc..
