| 摘 要： | 本项目的宗旨是通过小区试验、中区表证、大田示范，探讨二系杂交水稻培杂山青的增产优势．四年八造累计示范面积近万亩，加权平均亩产达５２０ ．７ ｋｇ，比对照种亩增产３８．３ ～９５ ．４ ｋｇ，增产率达８ ．１ ～２１．０ ％ ．实践结果表明，培杂山青具有根系发达，穗大粒多，高产优质高抗等优点，可因地制宜扩大面积推广．

| Abstract: | The increase yield Advantage of Pei Za Shan Qing,a bicross hybrid rice variety,was studied by plot experiment,middle stage evidence and set model in normal production.The experiment model ache amount to near a million in four years,the average output per ache up to 520.7 kilogram,it was higher over 38.3-95.4 kilogram than that of contrast variety,the increase rate got 8.1-21%.The resuits show that PeiZaShanQing possessed stronger root system,grater grain,high yield,excellent quality and good resistence to insect and desease.Therfore,this variety can expand culture ache accoding to natual condition. |
