| 摘 要： | 改性膨润土载体玉米专用复混肥是由膨润土分别与尿素、硫酸铵、磷酸一氨、氯化钾等按一定的比例混合，经过特殊的生产工艺制成。三年的田间试验表明，改性膨润土载体玉米专用复混肥具有显著的增产效果，比施用普通肥料增产6．9％；改性膨润土载体玉米专用复混肥利用率51．1％，等养分量普通肥料利用率35．6％。施用改性膨润土载体玉米专用复混肥比等养分量普通肥料利用率提高15．5％。

| Abstract: | The corn's special complex and mixed fertilizer treating modified-bentonite as carrier is made by mixing bentonite with urea, ammonium sulfate, one ammonium phosphate, potassium chloride and so on, and through a special production technological process. The result of three year's experiment in the field makes it clear that the corn's special complex and mixed fertilizer treating modified-bentonite as carrier has more remarkable effect on increasing production, and increase the production 6.9% than the general fertilizer. The utilization ratio of the corn's special complex and mixed fertilizer treating modified-bentonite as carrier is 51.1 %, but the utilization ratio of the equal nutrient general fertilizer is 35.6%. So the utilization ratio of the corn's special complex and mixed fertilizer treating modified-bentonite as carrier is raised 15.5% than the equal nutrient general fertilizer. |
