Description
技术领域
该发明涉及一种农用微量元素肥料，涉及氧化锌悬浮剂及其组成成份。
技术背景
随着高品质蔬菜、果品的生产需求，在我国植物保护护领域中，农用微量元素肥料应用越来越广。在我国果树区，缺锌是常见的现象。缺锌症状主要是植物叶片褪绿黄白化，叶片失绿，脉间变黄，出现黄斑花叶，叶形显著变小，常发生小叶丛生，称为“小叶病”、“簇叶病”等。严重影响蔬菜和果树的生长，并影响产品的品质。
在现阶段，我国种植业给蔬菜和果树直接补锌多采用硫酸锌，施用方法一是土壤追肥的方式施用；二是直接叶面喷施硫酸锌。根外追肥方法由于吸收慢、吸收不完全的原因，适用于预防缺锌或缺锌初期使用。硫酸根残留土壤，长久后会使土壤板结。农户发现果树缺锌时，缺锌往往已到比较严重的程度，这时只有进行叶面施用。叶面喷施硫酸锌，可以迅速补锌，但硫酸属酸性无机化学品，而且有效锌含量低，用量大，极易产生药害。因此，需要寻找更高效，吸收快，安全，而且适用于作物叶面吸收的补锌药剂。
氧化锌是一种常用的化工产品，多用于橡胶和涂料行业。氧化锌是一种粉状固体，含锌量高，但直接施用，作物叶片不能吸收。将氧化锌配制成合适的制剂是关键。目前，在我国氧化锌悬浮剂的制剂配制及应用尚无人报道。
发明内容
本发明的目的就是为了克服现有果树补锌技术中速度慢、易产生药害、易产生环境污染或不易吸收等缺点而开发的一种高含量、环保型、易吸收利用率高的氧化锌悬浮剂。悬浮剂是水性化剂型，兼有环保和成本低的特点，是目前农药制剂加工发展的一大趋势。
本发明的目的是由以下技术方案实现的，氧化锌悬浮剂的有效成份是氧化锌，其特征在于该制剂为高浓度黏稠状白色液体。其成份含量以质量百分比计为：
氧化锌原粉：10％-80％
润湿剂：2％-7％
分散剂：3％-10％
防冻剂：2％-6％
消泡剂：0.3％-1.0％
增稠剂：0.1％-0.8％
稀释剂：2.2％-84.6％
其中：
润湿剂可以是壬基酚乙氧基化合物(10EO)、苯乙基酚聚氧乙烯醚缩合物、烷基酚聚氧乙烯醚甲醛缩合物、烷基苯磺酸钠、烷基硫酸钠、烷基磷酸钠、苯乙基酚聚氧乙烯醚硫酸钠及烷基酚聚氧乙烯基硫酸钠之一种。
分散剂可以是萘磺酸钠甲醛缩合物、二烷基奈磺酸钠、苯乙基酚聚氧乙烯醚甲醛缩合物、烷基萘磺酸钠甲醛缩合物、脂肪醇醚丁二酸半酯磺酸钠、壬基酚酯丁二酸半酯磺酸钠、木质素磺酸盐、木质素磺酸钠、木质素磺酸胺、脂肪醇醚磷酸配、壬基酚醚磷酸酯、聚氧乙烯聚氧丙烯嵌段共聚物之一种。
防冻剂可以是乙二醇、丙二醇、丙三醇、聚乙二醇、乙二醇甲烷基醚之一种。
消泡剂可以是有机硅、甲醇、乙醇、异丙醇、仲丁醇、磷酸三丁酯、磷酸三辛酯、磷酸戊辛酯、聚丙二醇及其衍生物、脂肪酸聚氧乙烯酯、油酸之一种。
增稠剂可以是黄原胶、甲基纤维素、羧甲基纤维素羟乙基纤维素、无水丁二酸-苯乙烯共聚物、无水丁二酸-异丁二烯共聚物、之一种。
稀释剂是水。
本发明中由于加入不同成份和不同配比的助剂，使得本发明具有活性组分含量高，环境污染小，分散速度快，分散性能好及热贮性能稳定等优点。在实际应用中，补锌速度快，用药量少，安全性能好。
