Description

一种西瓜专用配方肥料配方
技术领域
本发明涉及一种土壤肥料配方，具体的说是一种专用于西瓜的肥料配方。
背景技术
申请人长期致力于江苏省南京市江宁区的土壤肥料工作。江苏省南京市江宁区适合种植西瓜的土壤属于沙壤土，有机质含量：8.478g/kg、碱解氮100.575mg/Kg、速效磷8.356mg/kg、速效钾57.475mg/kg。在这种土地上种植西瓜，在使用常规肥料的情况下，年亩产量约为320kg。
发明内容
本发明的目的是提供一种能改善土壤养分状况，调整化肥施用结构，促进西瓜增产增收的肥料配方，本发明所采用的技术手段是：施用一种肥料配方，其肥料含量为N∶P2O5∶K2O＝4～6∶14～18∶6～8。
此种肥料根据土壤测定结果配比而成，适合当地西瓜生长所需养分。本发明所述的肥料配方的肥料结合整地在西瓜覆膜前一次性底施，可提高西瓜的产量。
具体实施方式
实施例
江苏省南京市江宁区适合种植西瓜的土壤属于沙壤土，有机质含量：
8.478g/kg、碱解氮100.575mg/kg、速效磷8.356mg/kg、速效钾57.475mg/kg。根据当地的土壤测定结果，利用本发明西瓜专用肥料配方，对西瓜所需的大量元素氮、磷、钾及中量元素钙和微量元素铁、硼、锰、钼、锌等进行合理调配施用，从而达到西瓜增产增收。
西瓜专用肥料配方：其中含有三种大量元素氮、磷、钾。N-氮；P2O5-磷；K2O-钾。N：4～6；P2O5：14～18；K2O：6～8。共计组成10种配方组合。它们分别是：
N-P2O5-K2O的配比为：
(1)4:14:6 (2)4:16:6 (3)4:18:6 (4)4:14:8 (5)4:16:8
(6)4:18:8 (7)6:14:6 (8)6:18:6 (9)6:14:8 (10)6:18:8
本发明的适用范围是：
(1)土壤质地：沙壤土。(2)土壤有机质：≥10g/kg。(3)土壤肥力：中等以上。(4)目标产量：4000～5000kg。
本发明的施肥要求是：
(1)在每亩全层施用有机肥(农家肥)2000～3000kg的基础上，把准备好的本发明——西瓜专用肥料配方的肥料一次性底施。
(2)微量元素可根据当地土壤测定结果进行有针对性的施用。通常西瓜对铁、硼、钼、锰、锌等都有需求，但硼、钼最为敏感。当土壤有效硼≤5g/kg或有效钼≤1.5g/kg时，西瓜可能表现缺素症状，此时在西瓜苗期、始花期和盛花期各喷施一次0.2％的硼砂或0.1％的钼酸铵溶液，对西瓜增产有促进作用。
根据多年的实验，本发明的西瓜产量为4000～5000kg比常规亩施45％复合肥30kg的产量3500～3800kg亩增产量为500～1200kg，增产率为18％～25％。
