使用磷酸二氢铵化肥后效果不理想是怎么回事?
来源:http://www.jnjrh.com 日期:2019-10-29 发布人:admin
  很多多农民伯伯都特别的疑惑,为什么多年运用磷酸二氢铵,肥效性压根就不明显,也想不通为什么会呈现这种状况,下面氨基磺酸厂家--金日和给大家细致的引见一下吧!
  Many farmers and uncles are particularly puzzled about why the fertilizer efficiency of ammonium dihydrogen phosphate has not been obvious for many years, and they can't figure out why it will present such a situation. Let's give a detailed introduction to jinrihe, the manufacturer of sulfamic acid.
  使用磷酸二氢铵化肥后效果不理想是怎么回事?
  What's wrong with the effect of ammonium dihydrogen phosphate fertilizer?
  1、施用磷酸二氢铵后肥效并不理想,这是为什么呢?
  1. The fertilizer effect of ammonium dihydrogen phosphate is not ideal. Why?
  磷酸二氢铵是一种低氮高磷的二元复合肥料。在缺磷的土壤上,不论种什么作物,di一年都能够取得明显的增产效果。这是由于施肥对路,处理了作物需磷而土壤缺磷的主要矛盾。假如连年只施磷酸二氢铵,又不补充含氮的肥料,效果就不好了。这是由于土壤缺磷的旧矛盾处理了,而氮素缺乏就成了影响作物产量进步的新矛盾。
氨基磺酸
  Ammonium dihydrogen phosphate is a binary compound fertilizer with low nitrogen and high phosphorus. No matter what kind of crops are planted in the soil lacking phosphorus, di can increase production significantly in one year. This is due to the right way of fertilization, which deals with the main contradiction between crop phosphorus demand and soil phosphorus deficiency. If only ammonium dihydrogen phosphate is applied year after year, and the fertilizer containing nitrogen is not supplemented, the effect will not be good. This is due to the treatment of the old contradiction of soil phosphorus deficiency, and the lack of nitrogen has become a new contradiction affecting crop yield progress.
  2、为什么连年施用磷酸二氢铵肥效就不好了呢?
  2. Why is the fertilizer effect of ammonium dihydrogen phosphate not good?
  磷肥与氮肥不同,磷酸二氢铵施入土壤中只会产生磷的化学固定,降低肥效,而不像氮肥那样,有挥发、淋失和反硝化唆氮等损失,所以磷肥的实践应用率很高,这与氮肥应用率很低截然不同。所以长期施用磷酸二氢铵,土壤中速效磷的含量会进步很快。
  Different from nitrogen fertilizer, ammonium dihydrogen phosphate can only produce chemical fixation of phosphorus in the soil and reduce fertilizer efficiency. Unlike nitrogen fertilizer, there are losses such as volatilization, leaching and denitrification abetting nitrogen. Therefore, the practical application rate of phosphorus fertilizer is very high, which is quite different from that of nitrogen fertilizer. Therefore, long-term application of ammonium dihydrogen phosphate, the content of available phosphorus in soil will improve rapidly.
  合理施用磷酸二氢铵就必需依据土壤中速效磷含质变化的状况,及时调整施肥配方,配施磷钾肥,才契合均衡施肥的准绳,充沛发挥它的增产作用。
  The rational application of ammonium dihydrogen phosphate must be based on the change of available phosphorus content in the soil, timely adjust the fertilization formula, with the application of phosphorus and potassium fertilizer, in order to meet the criteria of balanced fertilization and give full play to its role in increasing production.
  3、农民应该如何合理施用磷酸二氢铵呢?
  3. How should farmers reasonably apply ammonium dihydrogen phosphate?
  一方面要正确认识磷酸二氢铵不是的肥料,磷酸二氢铵是一种低氮高磷的复合肥,用在缺磷的土壤上,不论种什么作物都有效。另一方面也应晓得磷肥不能替代氮肥,不要遗忘作物需求各种营养,长期用磷酸二氢铵做基肥,土壤必然会缺氮缺钾,所以一定要配施单质氮肥和钾肥,这样才干作到均衡施肥,作物单产才会进一步进步。
  On the one hand, it is necessary to correctly understand that ammonium dihydrogen phosphate is not a universal fertilizer. Ammonium dihydrogen phosphate is a kind of compound fertilizer with low nitrogen and high phosphorus, which can be used in the soil without phosphorus, no matter what crops are planted. On the other hand, we should also know that phosphorus can not replace nitrogen fertilizer, and don't forget that crops need all kinds of nutrients. If we use ammonium dihydrogen phosphate as the base fertilizer for a long time, the soil will inevitably lack of nitrogen and potassium, so we must apply simple nitrogen fertilizer and potassium fertilizer, so that we can achieve balanced fertilization and further progress in crop yield.
