- 摘要:
- 在钾素含量丰富的黄河谷地大白菜田，研究了在氮、磷施肥量相同的条件下增施不同量钾对大白菜生长发育及产量的影响。结果表明：在钾素含量丰富的碱性土壤中，增施钾肥可相应提高大白菜长势，并能明显提高大白菜的产量，但其增产效能随着施肥量的增加明显降低。
- Abstract:
- In potassium rich area of Chinese cabbage fields in the Yellow River valley，the effect of applying different amounts of potash fertilization on the growth and yield of Chinese cabbage were studied in the same condition of nitrogen and phosphorus level.The results showed that within a certain range of applying potash fertilizer could improve the growth and yield of Chinese cabbage in alkaline soil rich in potassium，but its production efficiency increased with the fertilizer supply significantly decreased.
