Abstract

本发明公开了一种玉米掺混肥配方,每生产2000斤掺混肥,用尿素1100斤、磷酸一铵700斤、氯化钾200公斤、搅拌掺混,配成氮磷钾三要素50%(29:15:6);该配方各肥源之间有很强的连应性,磷酸一铵掺合尿素能形成大分子聚合物,在土壤中逐渐释放养分;尿素掺混酸性磷酸一铵及氯化钾,可延缓脲酶对尿素的分解;酸酸一铵与氯化钾相结合,可在土壤中形成磷酸二氢钾及氯化铵;尿素在土壤中转换成氢氧化铵与磷酸一铵反应,生成磷酸二铵及水,也起到增肥效作用;所以该配方具有肥效高、价格低,针对性强等优点。

Description

一种玉米掺混肥配方
设计领域
本发明涉及测土配方施肥的化肥领域。
背景技术
针对在传统农业生产中,只重用氮肥的不科学施肥现象,我们按照平衡施肥“木桶定律”的原理,研究出一种含有氮磷钾全有的玉米掺混肥配方。
发明内容
本发明的目的在于按照平衡施肥“木桶定律”的原理,配制出一种含有氮磷钾全有的玉米掺混肥配方。
本发明采用如下的技术方案:根据生产需求,选用尿素、磷酸一铵、氯化钾、三种肥源,各肥源特性如下:尿素含氮46.3%;磷酸一铵含氮11%、磷44%;氯化钾含钾60%;该配方各肥源之间有很强的连应性,磷酸一铵掺合尿素能形成大分子聚合物,在土壤中逐渐释放养分;尿素掺混酸性磷酸一铵及氯化钾,可延缓脲酶对尿素的分解;酸酸一铵与氯化钾相结合,可在土壤中形成磷酸二氢钾及氯化铵;尿素在土壤中转换成氢氧化铵与磷酸一铵反应,生成磷酸二铵及水,也起到增肥效作用;所以该配方具有肥效高、价格低,针对性强等优点。
具体实施方式
本发明一种玉米掺混肥配方,每生产2000斤掺混肥,用尿素1100斤、磷酸一铵700斤、氯化钾200公斤、搅拌掺混,配成氮磷钾三要素50%(29:15:6);具体掺混参数看下表:

Claims (1)

1.一种玉米掺混肥配方,其特征在于:每生产2000斤掺混肥,用尿素1100斤、磷酸一铵700斤、氯化钾200公斤、搅拌掺混,配成氮磷钾三要素50%(29:15:6);该配方各肥源之间有很强的连应性,磷酸一铵掺合尿素能形成大分子聚合物,在土壤中逐渐释放养分;尿素掺混酸性磷酸一铵及氯化钾,可延缓脲酶对尿素的分解;酸酸一铵与氯化钾相结合,可在土壤中形成磷酸二氢钾及氯化铵;尿素在土壤中转换成氢氧化铵与磷酸一铵反应,生成磷酸二铵及水,也起到增肥效作用;所以该配方具有肥效高、价格低,针对性强等优点。
