不同田间配置方式对花生群体光合特性及产量的影响

摘要

以“农花5号”花生品种为供试材料，在每公顷15万穴、每穴2粒的条件下，设置小垄单行（T1）、大垄双行（T2）、大垄三行（T3）3种处理，研究了田间配置方式对花生群体光合生理参数、产量及产量构成因素的影响。结果表明：在花生群体光合生理参数方面，T2处理的叶面积指数、群体干物质积累量、光合势、群体透光率和群体生长率均高于T1和T3处理；在产量及产量构成因素方面，T2处理的出仁率、百果重和荚果产量亦显著高于T1和T3处理。%Field trial was carried out to study the effects of different field configuration modes on popula-tion photosynthetic physiological parameters and yield of peanut with the variety nonghua 5 under 1 50,000 plants per hectare,3 different field configuration modes were designed as single row on a narrow ridge (TI),double rows on a wide ridge (T2)and triple rows on a wide ridge (T3).The results showed that, in respect of photosynthetic physiological parameters,LAI,population dry matter accumulation,leaf area duration,population transmittance and population growth rate of T2 are higher than those of T1 and T3 . So are the shelling percentage,1 00-pod weight and yield in respect of yield and yield related factors .
