为进一步阐明花生单粒精播增产机理,以花育22为材料,通过田间盆栽模拟试验,研究单粒精播和双粒穴播对花生开花下针期、结荚期和饱果期根际土壤酚酸类物质含量、土壤酶活性及产量的影响。结果表明,单粒精播处理三次取样的根际土壤中均比双粒穴播少了咖啡酸,但饱果期根际土壤相比多了邻苯二甲酸和香草酸。单粒精播根际土壤中对羟基苯甲酸、阿魏酸、苯甲酸和肉桂酸含量均显著低于双粒穴播(P

In order to further explore the mechanism of single-seed sowing for improving yield in peanut (Ara-chis hypogaea L.), effects of single-seed sowing and double-seed sowing on phenolic acid content, soil enzyme activity of peanut rhizosphere soil at the flowering and pegging stage, the pod setting stage, and the pod filling stage were studied by using the method of field potted simulation experiment. The results showed caffeic acid in rhizosphere soil treated by single-seed sowing was less than that treated by double-seed sowing during the three sampling periods, but phthalic acid and vanillic a...
