摘要

通过马铃薯田间试验

研究了控释肥对马铃薯生长和土壤酶活性的影响。结果表明

与普通肥料相比

控释肥有利于提高马铃薯的株高、茎粗和叶绿素含量

分别提高5.94%

9.04%

5.55%

且控释肥减量20%仍不影响其促进作用。施用控释肥和普通化肥都可以促进土壤酸性磷酸酶和蔗糖酶活性

但控释肥平均比普通肥料的促进作用分别提高10.2%和14.62%

控释肥显著优于普通肥料;控释肥可促进脲酶活性

平均提高15.7%

而普通肥料会对其产生抑制;控释肥处理会对土壤过氧化氢酶活性造成一定的抑制作用

使其活性平均降低11.13%。与其他控释肥处理相比

控释肥减量20%

对脲酶活性的促进作用减小了9.41%

对酸性磷酸酶的促进作用减小了9.02%

对蔗糖酶的促进作用增加了5.56%

对过氧化氢酶的抑制作用降低了5.2%。

Abstract

Field experiment was conducted to study the effects of controlled-release fertilizer on potato growth and soil enzyme activities.The results indicated that:Compared with ordinary fertilizer

the plant height

stem diameter and chlorophyll were significantly increased by the application of controlled-release fertilizer

which respectively increased by 5.94%

9.04% and 5.55%.Furthermore

when the amount of controlled-release fertilizer was reduced by 20%

there was no significant change on the promotion effect.Both...
