剑麻同步营养肥增效减施技术研究

Study on the Technology of Increasing Efficiency and Reducing Application of Synchronous Nutrient Fertilizer for Sisal

与习惯施肥处理相比,同步营养肥处理剑麻新增叶片量显著增多,产量也提高了4.8%,表明施用剑麻同步营养肥,在化肥用量减少25%的条件下,剑麻新增叶片量明显提高,土壤NH4-N含量显著高于市售缓释肥、习惯施肥处理。

Compared with conventional fertilizer treatment,the amount of new leaves added to sisal is significantly higher in the synchronized nutrient fertilizer treatment,and the yield also increased by 4.8%,which indicated that the application of synchronized nutrient fertilizer to sisal,the amount of sisal leaves increased prominently under the condition of 25%reduction of fertilizer application,and the soil of NH4-Ncontent is notably higher than that of commercially available slow-release fertilizer and the conventional fertilizer treatment.
