补充资料：长效肥
| 长效肥 slow-release fertilizer 溶解度低或养分释放缓慢、肥效持久的一类化学肥料。又称缓效肥。以长效氮肥居多。通常分为：①合成缓溶性有机氮肥。由尿素与甲醛或乙醛等有机物直接反应而成。主要有脲醛肥料，如脲甲醛、脲乙醛和异丁叉二脲等。含氮量31％～35％。②合成缓溶性无机肥。以磷酸镁铵为主，含氮9.02％，磷11.95％，镁15.65％，溶解度很低，在土中主要靠微生物分解。③包膜肥。颗粒表面包有一层半透性或不透性（难溶性）膜状物以减缓养分释放速度。常用的包膜材料有聚乙烯、硫磺、磷酸镁铵、树脂、石蜡和沥青等。如硫磺包膜尿素是较成熟的品种。除上述长效肥外尚有长效磷肥、钾肥、如聚磷酸铵、聚磷酸钾等。长效肥多用作基肥，施一次可满足作物整个生长期需要。施用量过大也不易使作物烧苗、徒长、倒伏。施用品种应视土壤类型和作物种类而定。用于蔬菜和禾谷类作物时应掺混少量速效性化学氮肥。包膜肥用于具有间歇灌溉条件下的水稻效果最佳。 |
