摘要
试验以丰花1号为材料,研究了控释肥对花生产量及干物质积累的影响。结果表明:施用控释肥有利于保持较高的叶面积系数和净光合速率,促进茎叶和荚果的干物质积累,增加了单株结果数和饱果数,提高了百果重和百仁重,从而增加了花生产量。本试验条件下,每666.7m2施控释肥25 kg,增产效果最好,增产率达23.1%。
The field experiment was conducted to research the effects of controlled - release fertilizer on yield and dry matter accumulation of peanut variety Fenghua 1. The results showed that the application of controlled - release fertilizer was benefit to keeping higher leaf area index and net photosynthetic rate, promoted the dry matter accumulation of stem, leaves and pods, and increased the pod number of single plant, full - pod number, 100 - pod weight and 100 - kernel weight, thereby the peanut yield increased. Under the conditions of this experiment, the application of 25 kg of controlled - release fertilizer per 666.7m2 had the best effect on increasing peanut yield with the increasing rate as 23.06%.
