复合肥知识乐动电动老虎机

1.便宜和贵的内容是一样的吗?不一样的是，名牌的含量充足，而且每个的含量都只高不低，严格执行国家标准。有些厂家缺少的内容多达3-15个。按每个含量每吨50元左右计算，5个相差250元，均价每袋15元左右。2.许多肥料价格低廉，使用后效果良好。为什么?现在大多数厂家增加氮含量，降低钾含量，甚至没有。例如:15-15-15,45%含量制成20-10-5,35%含量使用后，幼苗强壮，后期可以脱育，但最终产量不会增加。

3.为什么廉价化肥的效果比名牌化肥好?碳酸氢铵当天生效，肥效期15天;氯化铵3天起效，肥效期25天，后期脱肥。尿素7天有效，肥效期45天。复混肥十天有效，肥效期90天。4.便宜就是贵，贵就是便宜，你说呢?一袋便宜的化肥每亩100斤，100元/亩。名牌肥料每亩70斤，90元/亩，真正省钱的好肥料。 5. Why do you feel that the output has not improved after using the famous brand fertilizer? The principle of nutrient return is that as much food as you harvest, you can absorb as much nutrients from the soil, and return as much as good chemical fertilizers. 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.复混肥和复合肥有什么区别吗?复合肥:高塔造粒、酸造粒、喷雾造粒，利用率提高60%。复合肥:滚筒造粒、圆盘造粒，利用率降低40%。9.9号和4号元素硫是怎么回事?三种主要元素是氮、磷和钾。按照现行国标，中间元素有4个以上，内容可以标注。硫含量为7%，是作物生长的四种必需元素。也就是说，农民花同样多的钱去买氮、磷、钾这三种元素，他们还买了硫这四种元素，这是负担得起的。 10. What is the difference between controlled release fertilizer and compound fertilizer? Controlled-release fertilizer is also a compound fertilizer. 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.
