控释复肥在盆栽玉米上的肥效研究

Effects of Controlled-Release Compound Fertilizers on the Growth of Potted Corn

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。

The experiment of controlled-release compound fertilizers' (CRFs) effect on corn growth in pot was studied by comprising with common compound fertilizers (CCFs). The chlorophyll reading, number of leaves, leaf area and growth potential of the corn treated by CRFs were significantly greater as compared to the corn treated by CCFs. The average dry matter weight of the plant for CRFs treatments of any rate was significantly higher than that of the corn treated by CCFs. The CRFs have the obvious advantage promoting the growth of corn. The biomass of the corn for the CRFs treatments was still higher than that of CCFs treatments even though the application rate of CRFs treatments was less than half of that of CCFs treatments.
