Abstract
本发明公开了一种稳定性复合(混)肥添加剂，各组分重量配比为苯基磷酰二胺∶2-氯-6-三氯甲基吡啶∶石蜡∶柠檬酸铵∶沸石粉＝2∶0.5～3∶2～5∶0.5～1∶4～8。本添加剂可以对稳定性复合(混)肥料的肥效期进行调整，明显提高氮磷钾的利用率，满足多种作物的需肥要求。
Description
技术领域
本发明涉及一种添加剂，尤其涉及一种稳定性复合(混)肥添加剂。
背景技术
2010年我国的化肥使用量在1亿吨以上，居世界第一，但是当年化肥的利用率仅为30％-35％，其中氮肥利用率30％-35％，磷肥10％-20％，钾肥40％-50％，远低于发达国家水平(50％-60％)。2010年我国氮肥损失量的经济价值在600亿-800亿。损失掉的氮肥对地下水体、表面水体及大气环境的不良影响日益严重。由于氮素在土壤中的转化速度过快，磷素和钾素很快被土壤固定，作物不能长时间吸收，还需要给作物后期多次追肥。提高化肥的利用率已成当务之急。为了解决肥料利用率低、肥效期短的的问题，国内外先后研究出了脲甲醛类缓释肥、稳定性肥料、包膜类控释肥及相关或者衍生产品。包膜肥料和脲甲醛类肥料由于生产工艺复杂，成本高，包膜材料不易降解，甲醛类有机溶剂易污染等缺点，目前推广缓慢，只在草坪、花卉上使用较多。稳定性肥料由于生产成本低、工艺简单、效果好、环境优良等优点，发展潜力巨大。美国、德国、日本等农业发达国家应用较多。但是国外目前使用的抑制剂均是单一的抑制剂，只能控制酰胺态氮转化到硝态氮过程中的部分过程，并未达到理想状态。
发明内容
本发明所要解决的技术问题是提供一种稳定性复合(混)肥添加剂，其可以对稳定性复合(混)肥料的肥效期进行调整，明显提高氮磷钾的利用率，满足多种作物的需肥要求。
为了解决上述技术问题，本发明采取以下技术方案：
一种稳定性复合(混)肥添加剂，其特征在于各组分重量配比为苯基磷酰二胺∶2-氯-6-三氯甲基吡啶∶石蜡∶柠檬酸铵∶沸石粉＝2∶0.5～3∶2～5∶0.5～1∶4～8。
上述各组分重量配比可以优化为苯基磷酰二胺∶2-氯-6-三氯甲基吡啶∶石蜡∶柠檬酸铵∶沸石粉＝2∶2∶3∶0.6∶6。
本发明采用两种抑制剂复合使用，可以控制酰胺态氮转化到硝态氮的整个过程，并通过使用量控制效果，解决了单一抑制剂的弊端。提高化肥利用率10％～15％，对氮磷钾利用率均有明显的效果；延长肥效期，最长可达150天，并在90～150天内可调控，满足作物整个生长期养分需求；减少农田硝酸盐淋溶和径流损失60％以上，降低氮氧化物排放65％以上，减少作物中硝酸盐积累量70％以上；真正实现一次性施肥，免追肥，节省劳动力。本产品的加工工艺简洁，主要设备为粉碎机，操作简单，同时对外界环境没有影响。嫁接到复合(混)肥生产线对现有的生产设备不需要进行大的改动，生产成本低廉。
具体实施方式
以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例一：
取五种原料苯基磷酰二胺(2公斤)、2-氯-6-三氯甲基吡啶(0.5公斤)、石蜡(2公斤)、柠檬酸铵(0.5公斤)、沸石粉(4公斤)投入到粉碎机中进行碎粉，细度为200目，采用具有内衬膜的包装袋进行填装即可。
实施例二：
取五种原料苯基磷酰二胺(2公斤)、2-氯-6-三氯甲基吡啶(3公斤)、石蜡(5公斤)、柠檬酸铵(1公斤)、沸石粉(8公斤)投入到粉碎机中进行碎粉，细度为200目，采用具有内衬膜的包装袋进行填装即可。
实施例三：
取五种原料苯基磷酰二胺(2公斤)、2-氯-6-三氯甲基吡啶(2公斤)、石蜡(3公斤)、柠檬酸铵(0.6公斤)、沸石粉(6公斤)投入到粉碎机中进行碎粉，细度为200目，采用具有内衬膜的包装袋进行填装即可。
实施例四：大田连续试验
在江苏水稻田进行连续五年试验，分别测定水稻田的微生物活性、有机质含量、土壤容重等指标，与没有使用添加剂的农民田地对照，没有出现异常。
实施例五：
在湖南、山东、江苏、甘肃、吉林等地试验点布置试验，与当地常规施肥作对比，分别提高肥料利用率11.7％、12.3％、14.9％、10.2％、13.7％。一次性作为底肥施入后，不再追肥，可以满足作物当季生长的养分需要，其中江苏水稻的生长期在150天左右，山东玉米早熟品种生长期在90天，通过调节添加剂的使用量，均可以达到肥效期。
实施例六：本品与其他常用的添加剂使用效果对照
