摘要

通过盆栽油菜试验，研究了控释肥残膜对土壤某些物理性质及油菜生长效应的影响。研究表明，向盆栽油菜中添加控释肥残膜后，土壤容重降低，孔隙度明显增加，土壤比重变化不大；在一定范围内，油菜叶片中叶绿素含量、叶片数及生物量都随土壤中控释肥残膜含量的增加明显提高，并且由于残膜的施用，油菜还原型Vc含量也有明显的提高，CRFRC2处理的还原型Vc含量高于其他处理；控释复合肥由于养分控释时间较长，在对油菜生长效应的影响上，与普通复合肥相比无明显差异；控释肥残膜在一定含量范围内对土壤和作物是有益的。

Abstract

Effects of Controlled Release Fertilizers residual coating(CRFRC) on soil physical property and growth of cole were studied in potted cole experiment.The results indicated that the soil bulk density decreased

the total porosity increased obviously

and the specific gravity changed little with Controlled Released Fertilizers residual coating.Controlled Released Fertilizers residual coating had effect on the growth of cole.The contents of chlorophyll

number of leaves

leaf area and growth potential of the cole had been increased obviously with the added of residual coating content.Besides

the reductive Vc content of cole had been increased by Controlled Released Fertilizers residual coating and the reductive Vc content of CRFRC2 treatment was higher than other treatments.In addition

Controlled Release Fertilizers and common compound fertilizers had no differences in the growth of cole because the release time of CRFS was a little longer.As a result

Controlled Released Fertilizers residual coating was beneficial to soil and plants if it was controlled in appropriate extension.
