摘　　要：为研究连作对花生生长发育的负面影响,对连作花生生长发育过程中的农艺性状、植株营养、叶绿素含量、净光合速率、干物质重等重要性状调查以及测产,结果表明,农艺性状、植株营养指标、叶绿素含量、净光合速率、干物质重以及产量随着连作年限的增加而减少,表现为表现为正茬>连作2年>连作3年>连作4年>连作6年和连作10年,连作6年和连作10年相近。因此,连作对花生生长发育有明显的抑制作用,连作年限越长抑制作用越大,在连作多年抑制作用达到一定程度后不再增强。For the negative effect of continuous growth of peanut continuous cropping during the cropping on the growth and development of peanut, on the development of Agronomy. plant nutrient , chlorophyll content, net photosynthetic rate, dry matter weight survey important traits and yield , results show agronomic traits, plant nutrition level, chlorophyll content, net photosynthetic rate, dry matter weightand yield decreased with the increase of continuous cropping years. ,demonstrated in 2 years of continuous cropping rotation 〉 re- planted 3 years 〉 replanted 4 years 〉 6 years of continuous cropping and continuous cropping for 10 years, 6 years of continuous cropping and continuous cropping 10 years close . Therefore, continuous cropping on pea- nut growth was inhibited, continuous cropping years longer the greater the inhibition, inhibition in continuous cropping years after reaching certain level？ no longer enhanced.
