本文对采用流化床包膜技术制作的控释复肥进行了玉米盆栽试验,并与普通复肥进行了肥效对比。从玉米的长势变化来看,控释复肥处理的叶绿素值、叶面积、叶数和生长势均比普通复肥有明显优势。植株的平均干重在各施肥处理上均大于普通复肥,而且在施用量减少一半以上的情况下,仍能获得高于普通复肥的生物产量。
In this paper, the fluidized bed coated with the production of controlled-release compound fertilizer corn pot experiments, and compared with the general compound fertilizer efficiency. Changes from the corn growth point of view, the controlled release compound fertilizer treatment of chlorophyll value, leaf area, leaf number and growth potential than ordinary compound fertilizer has obvious advantages. The average dry weight of plants was higher than that of common compound fertilizers in all fertilization treatments, and the biomass yield higher than ordinary compound fertilizers was still obtained when the application amount was reduced by more than half.
