1.廉价和昂贵的内容是一样的吗?不一样,着名品牌的内容就足够了,每个内容只有高,不低,国家标准严格实施。一些制造商缺乏3-15的内容。基于每吨大约50元的每吨,差异为250元,平均价格为每袋约15元。2.许多肥料价格低廉,使用后表现良好。为什么?现在大多数制造商增加了氮含量并降低了钾含量,甚至没有。例如:15-15-15,45%含量为20-10-5,使用35%含量后,幼苗将强大,可以在后期延长,但最终产量不会增加。

3.为什么廉价肥料的影响比品牌肥料更好?碳酸氢铵在同一天生效,肥料效应为15天;氯化铵在三天内生效,肥料效应为25天,并在后期延迟。尿素在七天内有效,肥料效应期为45天。复方肥料在十天内有效,肥料效应期为90天。4.Cheap很贵,昂贵很便宜,你说什么?一袋廉价的化肥是每亩100斤,100元/亩。品牌肥料为70斤,每亩70元,90元/亩,良好的肥料,真正节省了钱。5.为什么在使用着名品牌肥料后,输出尚未改善?营养返回的原则是,尽可能多的食物收获,您可以吸收土壤中的营养素,并返回好化学肥料。 That is to say, after three consecutive years of inferior chemical fertilizers, the chemical fertilizers will be recovered immediately. , Good chemical fertilizer for three consecutive years, even if there is no chemical fertilizer for one year, the output will not be low. 6. Why some small factories have passed the chemical fertilizer test, but the prices are different from those of large factories? Now the functional departments only test N, P, and K. Many small factories can just do the superficial articles; the famous brand factories also need to add various medium and trace elements, about 300 yuan per ton, to meet the needs of high crop yields. 7. is there any difference between potassium sulfate type and potassium sulfate? Potassium sulfate type is produced by dechlorination of potassium chloride in the compound fertilizer production process. It is produced according to potassium sulfate, and the chloride ion is about 3-5%. Potassium sulfate compound fertilizer is produced by pure potassium sulfate, and the chloride ion is less than 3 , Suitable for various crops.

8.复合肥料和复合肥是否存在差异?复合肥料:它是高塔造粒,酸造粒,喷雾造粒,利用率高60%。复合肥:滚筒造粒,圆盘造粒,利用率降低40%。9.九和四元素硫磺怎么了?三个主要元素是氮,磷和钾。根据目前的国家标准,有四个以上的中间元素,可以标记内容。含有7%的硫,是作物生长的四个基本要素。也就是说,农民花了相同数量的钱购买氮,磷和钾的三个要素,他们还购买了硫磺的四个要素,这是价格实惠的。10.控释肥料和复合肥料之间有什么区别?控释肥也是复合肥料。 The first generation is resin or sulfur-coated controlled-release; the second generation is that the intelligent controlled-release factor is directly added to the fertilizer. The fertilizer validity period can reach 120 days, and the utilization rate can reach 70.
