通过盆栽试验,研究了坡缕石包衣肥的增产及缓释效应.结果表明:施用坡缕石包衣的磷酸二铵225 kg·hm~(-2)后,油菜有效结角数和经济产量分别较对照提高了2.27 %和255.33 %;油菜后复种小麦,施用坡缕石包衣肥300 kg·hm~(-2)后,小麦生物产量比对照增加了57.67 %.在油菜生育后期,施用坡缕石包衣肥后油菜叶绿素、蛋白质、可溶性糖含量均较对照高,丙二醛含量较对照低,说明施用坡缕石包衣肥可提高生育后期油菜的抗衰老性和抗逆性,缓释效果较好.

The yield-increasing and slowly releasing effects of palygorskite coated fertilizer were investigated with pot experiment. The result showed that application of diammonium phosphate coated with paly-gorskite at 225 kg · hm~)(-2),the effective siliquae and yield of rape (Brussica napus) increased by 2. 27 % and 255. 33 % respectively compared with control. The biomass of wheat which planted after rape increased by 57. 67 % when compared with control at 300 kg ·hm~(-2). The content of chlorophyll, protein and soluble sugar in rape at latter growth stage were higher than that of the control, while MDA content was lower. It is suggested that palygorskite coated fertilizer shows good anti-aging and adverse-resistance characteristics, it also has certain slow release property on diammonium phosphate.
