| 摘 要： | 本试验研究了活化剂对玉米各生育时期土壤有效磷含量和玉米产量的影响,得出以下结果:施用活化剂能有效减缓土壤有效磷下降的趋势,提高玉米产量,其中以活化剂H2(450 kg/hm2)效果最好,其次为柠檬酸铵(15 kg/hm2)和腐植酸(150 kg/hm2),分别比对照(处理3)增产9.32%、5.99%和4.99%。活化剂主要通过增大千粒重和穗粒数来增加玉米产量。相关分析得出,玉米产量与抽穗期土壤有效磷含量的相关性最大,应掌握好抽穗期合理施肥。

| Abstract: | Effects of phosphorus activator(PA) on amount of Olsen-P and corn yield in black soil were studied in order to conduct fertilizing rationally.The results showed that PA could slow the trend of decreasing of Olsen-P in black soil and enhance corn yield.H2(450 kg/hm2) was the best PA which enhanced corn yield 9.32% more than CK.Following was citrate(15 kg/hm2) and HA(150 kg/hm2),which enhanced corn yield 5.99% and 4.99% more than CK,separately.PA could enhance corn yield mainly through increasing 1000-seed we... |
