重化肥,轻有机肥;重氮肥,轻磷、钾肥,忽视微肥;重产量,轻质量;施用方法陈旧落后。

2、各种化肥的养分含量是什么?

碳酸氢铵N 17%;二铵N

18% P2O5 46%;硫酸钾K2O

50% ;氯化钾K2O 60% ;尿素N

46% 。

3、硫酸钾型、氯化钾型复合肥的不同用法?

氯敏感作物:烟草、茶叶、马铃薯、甘薯、甜菜、甘蔗、西瓜、草莓、苹果、梨、柑橘;盐碱地、大棚保护地——以上作物和土壤适用硫酸钾型复合肥。

喜氯作物:棉花、水稻、猕猴桃——以上作物及水田适用氯化钾型复合肥。

4、化肥的利用率?

氮肥35% ;磷肥10-20%

;钾肥50-60% 。

5、鉴别真假化肥的方法?

看:包装是否正规、颗粒是否光滑均匀;

摸:摩擦肥料看是否出油、出汗;

溶:残渣越少越好;

烧:冒泡、熔化、燃烧。

6、化肥为何会烧苗?

原因:化肥施用量过大或是种子离根系太近。

原理:施肥增加了土壤水中盐的浓度,或是化肥与根系直接接触,使得根系周围土壤养分浓度过高,本着水分是从低浓度向高浓度方向流的原理,根系中的水分外流到土壤中,使种子或幼苗的根中的水外流,造成烧苗。

7、如何避免烧苗?

种肥隔离或少量多次施肥。
