控释肥料在很多试验中都被证明是可以有效的提高作物产量。本试验通过在具体的条件下,在低肥力水平的土壤上种植菠菜,并分别施用控释复合肥、普通复合肥、控释尿素和普通尿素,测定和分析菠菜的长势。研究表明在此条件下施用控释复合肥并不能有效的提高作物的产量,施用控释尿素在较高的水平时,可提高作物产量。
Controlled release fertilizers have proven to be effective in increasing crop yield in many experiments. In this experiment, spinach was planted on soil with low fertility level under specific conditions, and controlled release compound fertilizer, common compound fertilizer, controlled release urea and ordinary urea were respectively applied to determine and analyze the growth of spinach. Studies have shown that application of controlled-release fertilizer under these conditions does not effectively increase crop yields. Application of controlled-release urea at higher levels can increase crop yields.
