为研究坡缕石包衣肥的缓释效应及机理,以春小麦为指示作物,进行盆栽试验。结果表明,坡缕石包衣磷酸二铵有利于肥料缓释,使春小麦千粒重、经济系数、经济产量和生物产量均有不同程度增加,并能有效促进春小麦体内生化物质的转化,达到延缓衰老的作用。坡缕石可作为肥料的新型缓释包衣材料在生产中得以应用。
In order to study the sustained-release effect and mechanism of palygorskite coated fertilizer, the spring wheat as the indicator crop was potted experiment. The results showed that the palygorskite coated with diammonium phosphate was beneficial to the slow release of fertilizer, the thousand kernel weight, economic coefficient, economic yield and biological yield of spring wheat increased to some extent, and could effectively promote the transformation of biochemical substances in spring wheat, effect. Palygorskite can be used as a new type of sustained-release coating fertilizer in production.
