摘　　要：选用高产大花生品系农大 81 8,研究起垄覆膜种植喷施硕丰安对花生生长的调控作用。结果表明 ,盛花期施用硕丰安可抑制植株旺长 ,降低植株高度 ,提高饱果期植株冠层光截获率 ,提高主茎顶叶的光合速率(Pn)、光吸收率、叶绿素含量以及玉米素核苷 (ZR)含量和硝酸还原酶 (NR)活性 ,降低叶斑病的发病率 ,荚果产量达 5 95 3 .9kg/hm2 ,比对照处理增产 3 6.4 %。The effect of Shuofengan on the peanut growth was investigated with a high-yield line Nongda 818 under the plastic-film-covered cultivation in field. The result showed that peanut plant height was reduced, the light capture efficiency of plant canopy was improved, and the photosynthetic rate, light absorption coefficient, chlorophl content, nitrate reductase activity and zeatin riboside content were increased after Shuofengan applicated in the full-blooming stage. Shuofengan could reduce peanut leafspot incidence, and it promoted Nongda 818 to give a yield of 5 953.9kg/hm 2 which outyielded the control treatment by 36.4%.
