| 摘 要： | 通过田间试验在宁夏灵武农场研究了增施钾肥对油葵产量的影响,以期为指导当地农户的合理施肥提供依据。结果表明:与对照比较,N、P处理和N、P、K处理均降低了油葵的空粃率,提高了油葵的千粒重,显著提高油葵的产量。N、P处理和N、P、K处理的产量分别比对照提高了37.2%和73.0%。同常规只施用N、P处理比较,增施钾肥(N、P、K处理)油葵产量提高了26.1%,差异达到显著水平。在当地土壤肥力条件下要进一步提高油葵的产量,增加经济效益,必须改变农民的传统施肥习惯,增施钾肥,平衡施肥。

| Abstract: | A field experiment was carried out in Ningxia Lingwu farmland to study the effect of potassium fertilizer on sunflower yield.The results showed that compared to CK treatment application fertilizer can significantly increase sunflower yield,N,P treatment and N,P,K treatment can decrease sunflower rate of empty husks.N,P treatment and N,P,K treatment sunflower yield were increased 37.2% and 73.0% compared to CK treatment,respectively.Only the balance supply of N,P and K fertilizer can make the sunflower yield... |
