摘要
采用配方施肥与常规施肥方法结合大区试验对花生植株生长状况、产量、经济效益及土壤养分含量进行研究。结果表明,多营养元素配方施肥对促进植株生长效果明显,能明显提高花生产量,增加花生经济效益。目前条件下,以每hm2施肥量N 127.2kg、P2O560.2kg、K2O 90.0kg为宜。
The effects of balanced fertilization and conventional fertilization on peanut growth, output, profit and contents of soil nutrients were studied through field trial. The study indicated that the balanced fertilizing treatment can obviously promote the stem growth and increase both the output and the profit. Under current production condition, the optimum amount of the balanced fertilization should be N 127.2 kg/hm2 ; P205 60.2 kg/hm2 , and K20 90.0 kg/hm2.
