A gypsum treatment stone as filling material for production of four winged bean fertilizer formula with phosphorus, for most of the production of compound fertilizers in China enterprises are using kaolin as filler, the use of phosphogypsum processing stone as filler, due to strong acid treatment of phosphogypsum, Portland medical stone, can a variety of beneficial trace elements in Maifan stone in water is easily converted into Nengrong sulfate crop absorption, not only improve the efficiency but also than using kaolin as filler material savings of 100 yuan per ton. According to soil testing data, in accordance with the principle of balanced fertilization \law of cask\, according to the proportion of 1:1, the phosphogypsum and stone were mixed at room temperature for 3~5 days and then heap stuffy, according to the design of nutrients, filling 1.2 ~ 1.4 with the compatibility of crushed urea 3.4 ~ 3.6. Ammonium phosphate is 0.9 ~ 1.1, 1.9 ~ 2.1 superphosphate, potassium chloride 2.1 ~ 2.3, mixing granulation. Dry packaging, put on the market for production, the compound fertilizer nitrogen, phosphorus and potassium total nutrients is 37%, three to 17:7:13. Because the formula is scientifically matched on the basis of soil testing, it has strong pertinence. After many years of tests, it has been proved that a bag of compound fertilizer per mu can produce more than 3~5 bags of urea.
【技术实现步骤摘要】
设计领域本专利技术涉及测土配方施肥化肥领域，具体涉及用磷石膏处理麦饭石为填充料，配伍其它肥源，生产四棱豆专用复混肥。
技术介绍
我国大多数生产复混肥企业，大多用白坩土作填充料，现改用磷石膏处理麦饭石为填充料。由于磷石膏酸性极强，处理硅酸盐麦饭石，可使其转化成能溶于水易被作物吸收的硫酸盐，使麦饭石中多种有益微量元素，能被作物吸收利用，从而不仅提高了肥效。而且，还使每生产一吨复混肥料，其成本还能节支100多元。用其填充料，根据测土化验数据，按照平衡施肥“木桶定律”的原理，配伍其它肥源，生产出针对性很强的四棱豆专用复混肥。
技术实现思路
本专利技术用于四棱豆的施肥，达到增收节支的目的。本专利技术采用如下的技术方案：首先，按1:1的比例，把磷石膏与麦饭石进行掺混，在常温下堆闷3～5天，使酸性极强的磷石膏，把硅酸盐麦饭石转化成能溶于水易被作物吸收的硫酸盐。用其填充料1.2～1.4份，配伍粉碎后尿素3.4～3.6份，磷酸一铵0.9～1.1份，过磷酸钙1.9～2.1份，氯化钾2.1～2.3份，掺混造粒。烘干包装，投放市场，用于生产，该复混肥氮、磷、钾总养分为37%，三者比为17:7:13。由于该配方是在测土化验的基础上科学配比而成，具有很强的针对性，经多年多点试验证明，每亩施一袋该复混肥，可比单施3～5袋尿素的产量高。具体实施方案首先，按1:1的比例，把磷石膏与麦饭石进行掺混，在常温下堆闷3～5天，使酸性极强的磷石膏，把硅酸盐麦饭石转化成能溶于水易被作物吸收的硫酸盐。用其130公斤，掺混粉碎后的尿素350公斤，磷酸一铵100公斤，过...
