The invention provides a method for preparing urea ammonium phosphate mixed with potassium rich alkali lime soil potato formula fertilizer, the fertilizer innovation is based on the characteristics of potassium rich alkali lime soil, selection of urea, monoammonium phosphate, two kinds of fertilizer, using ammonium phosphate and urea to improve efficiency the company shall, with fertilizer, reduce the amount of fertilizer, fertilizer production is an advanced way to implement zero growth; two is the price low, with the addition of ammonium phosphate synthase with 50% urea nitrogen and phosphorus fertilizer is two yuan, the price is only the equivalent of 38% two yuan phosphorus nitrate compound fertilizer price is three; high efficiency, according to many field experiments in phosphorus and nitrogen conditions, formula fertilizer mixed with ammonium phosphate and urea than with urea fertilizer per mu yield of sweet potato 7.8% ~ 8.9% with diammonium phosphate doped; four is in production in the promotion of high efficiency, low price The sweet potato formula fertilizer, which is strong, can increase the income for the farmers to build up a well-off society and open up a new space.
【技术实现步骤摘要】
一种用磷酸一铵掺混尿素配制富钾偏碱石灰性土壤甘薯配方肥
本专利技术属配方施肥领域,特别是一种用磷酸一铵掺混尿素配制富钾偏碱石灰性土壤甘薯配方肥。
技术介绍
我们面对在农业生产中出现的“无论水地旱地,一味追求硝酸磷肥;不管土壤酸碱,一直迷信磷酸二铵;不按作物需肥规律,长年单施氮肥;不看化肥特性,碳酸氢铵与钙镁磷肥连年混用”的不科学施肥现象,造成农作物产量长年徘徊不前的被动局面;按照国家农技推广中心,改“配方施肥”为施“配方肥”的推广意见,根据河南省大都是石灰性土壤,急需施用磷酸一铵这种新型酸性肥料的实情,及时较早的开展了磷酸一铵掺混尿素配制富钾偏碱石灰性土壤的甘薯配方肥的研究。
技术实现思路
综上所述,为了克服现有技术问题的不足,根据石灰性土壤富钾偏碱的土壤特性,按照“地力分级法”,研究一种用磷酸一铵掺混尿素配制富钾偏碱石灰性土壤甘薯配方肥。本专利技术的创新点是根据富钾偏碱石灰性土壤的特性,选用磷酸一铵、尿素两种肥源,利用磷酸一铵与尿素之间提高肥效的连应性,配制配方肥,减少施肥量,是落实化肥产量零增长的先进途径;二是价格低,用磷酸一铵掺合尿素配成50%的氮、磷二元配方肥 ...
