摘　　要：研究不同种植技术和种植密度对吉林省多粒型花生吉花2号主要农艺性状和产量的影响,筛选适宜吉林省生态环境的种植技术和最佳种植密度,完善吉花2号配套高效栽培技术。采用2种种植技术及5个种植密度(1.79×10^(5)、2.02×10^(5)、2.30×10^(5)、2.69×10^(5)、3.23×10^(5)株/hm^(2)),研究特定时期花生光合指标及产量变化。结果显示,吉花2号采用小垄双行种植技术、种植密度为2.02×10^(5)株/hm^(2)时生育期最短,较双粒穴播种植技术生育期提前1~2 d;植株的株高最小,有利于地下部干物质积累;叶面积系数最大,总光合势最大;产量最高(3651.15 kg/hm^(2)),较双粒穴播种植技术增产10.17%。小垄双行种植技术在不同密度下,吉花2号产量都高于双粒穴播种植技术。因此,小垄双行种植技术在生产上应大力推广。Under different planting technologies,we researched the effects of different planting densities and planting technologies on major agronomic characters and yield of Jihua 2 in Jilin Province.We screened the proper planting technology and planting density for ecological environment of Jilin Province and improved the supporting efficient cultivation technology of Jihua 2.Two planting technologies and five planting densities(1.79×10^(5),2.02×10^(5),2.30×10^(5),2.69×10^(5),3.23×10^(5)plants/hm^(2)),we researched the changes of photosynthetic index and yield of peanut.Results showed that treatment of small ridges and double rows and 2.02×10^(5)plants/hm^(2)planting density had the shortest growth period,which was 1-2 d earlier than that of double-grain cave sowing.Besides,the plant was shortest,which was suitable for underground dry matter accumulation,the leaf area index and total photosynthetic potential were the maximum.The yield of treatment was the highest,which was 3651.15 kg/hm^(2),and enhanced by 10.17%compared with that of doublegrain cave sowing.Thus,the production technology of small ridges and double rows should be vigorously promoted.
