Fertilizer synergism additive and its manufacturing and using method

Abstract

The present invention is one kind of chemical fertilizer synergizing additive, which is brilliant yellow mixture powder of 2, 4-dinitrophenol (sodium) 0.1-60 wt%, alpha-naphthylacetic acid or sodium alpha-naphthylacetate 0.1 -40 wt%, indolacetic acid or sodium indolacetate 0.1-30 wt%, and dodecyl benzene sulfonic acid or sodium dodecyl benzene sulfonate 0.1-10 wt%. It is added into composite fertilizer in the amount of 0.01-10 wt%, and the mixture is pelletized. It can raise the utilization rate of chemical fertilizer, reduce use amount of chemical fertilizer, reach obvious yield increasing effect, reduce environmental pollution and lower agricultural production cost.

Description

[0001] Field [0002] The invention belongs to chemical fertilizer synergistic additives, in particular to a chemical fertilizer synergistic additive and its manufacturing and application methods. technical background [0003] With the growth of world population, the development of industry and the continuous expansion of urban scale, a large amount of arable land is occupied, which reduces the area of ​​arable land year by year. In order to meet people's demand for food and agricultural by-products, it is necessary to increase food production, and the application of chemical fertilizers is to increase efficient means of food production. At present, traditional chemical fertilizers such as: nitrate nitrogen fertilizer, ammonium nitrogen fertilizer, amide nitrogen fertilizer, cyanamide nitrogen fertilizer, etc., all have a certain effect on increasing production. Due to the fast volatility and low utilization rate of this kind of chemical fertilizer, if you want to increase pro...
