摘要
1990年,对湖南省12个县,780农户水稻品种入户率的调查指出,品种入户率的地域差异,平原地区最高,边远山区最低;杂交组合入户率高于常规稻品种。一个品种推广的使用周期,一般为8~10年。还对提高品种入户率提出了如下建议:大力选育高产、优质、多抗的新品种,严格进行品种区域试验与审定工作,加强宣传示范推广,做到边试验示范,边繁殖种子,建立健全种子繁育基地和增设供种网点,保证及时优惠供种。
We investigated the family introduction percentage of rice varieties (the FIP) for 780 fami-lies in 12 counties over Hunan Province in 1990,and studied thecorresponding extention wayhow to increase the FIP.The result showed that there was a difference of the FIP among investi-gated regions,of which the FIP was highest in plain regions,and lowest in far mountai(?)egion-s.The FIP was higher in hybrid rice than in commonrice.In general,the extention period of avariety was as long as 8—10 years.As for the corresponding extention way of the FIP,we alsosuggested as follows:1) trying to sellect new varieties with high yielding,multiple resistanceand high quality;2) making the appreciation and regional test of new varieties;3) setting upbases of seed production and sites of seed supply;4) making experimental examples of highyielding of new variety.
