摘要
1988—1990年在我国重要的胡椒产区——海南省万宁县,进行胡椒施用不同配方复合肥的田间试验。结果表明,N:P_2O_5:K_2O为12:6:13加微肥的配方是胡椒专用肥的较佳配方,施用效果柑当或优于N、P、K比为15:15:15的进口复合肥,比当地常规施肥增产20.2%,能节省肥料成本,有显著的经济效益,可在试区大面积推广。
Field experiments on effect of compound fertilizers of different prescription on pepper had been carried out in Wannin county, Hainan province, in 1988—1990. Results showed that the most effective prescription of the compound fertilizers was made up of N, P_2O_5, K_2O and some minor elements, the ratio of the former three compositions was 12:6:13. The effect of this compound fertilizer is equal to or better than the imported compound fertilizer which the ratio of N:P_2O_5:K_2O is 15:15:15. Pepper yield obtained by applying it was 20.2% higher than that obtained by traditional fertilization. It could reduced the cost and had evident economic benefit. So this special compound fertilizer could be applied widespread in the experimental area.
