Abstract:
Straw charcoal,perlite and chemical amendment were used as test materials,a pot experiment was conducted to study the effects of three kinds of soil amendments on soil compaction,soil nutrients and crop plant height under different application rates.In order to select the best application ratio of soil amendments to meet multiple objectives.The results showed that the optimal plant height reagent was 6% chemical amendment,and the optimal compaction reagent was 2% perlite.The optimal soil available potassium,available phosphorus,total nitrogen and organic matter were 4% straw charcoal,10% chemical amendment,8% straw charcoal and 2% chemical amendment,respectively.When each reagent was used for different detection indexes,the indicator values were not the same.Under the action of the three modifiers,the changes of the detection index values fluctuates greatly,and the single modifier can′t meet the expected values of multiple indicators.In the follow-up,the effectiveness of different types and ratios of modifiers need to be studied.
