Abstract

The invention relates to a novel compound fertilizer and a preparation method thereof. The novel compound fertilizer is prepared from, by weight, 10-15 parts of ammonium phosphate, 8-12 parts of phosphorus nitrate, 2-6 parts of TBHQ, 3-5 parts of potassium nitrate, 3-5 parts of monopotassium phosphate, 20-25 parts of urea, 3-5 parts of monopotassium phosphate, 2-5 parts of diammonium phosphate, 20-25 parts of rape seed cakes, 10-20 parts of tea seed cakes, 10-20 parts of chicken manure and 3-8 parts of fermentation powder. The novel compound fertilizer is easy in material acquisition, low in cost, sufficient, rich in nutrition component, less prone to causing soil acidification and basification and effective in alleviation of soil problems, absorption capacity of crops is improved, growth acceleration and yield increase are realized, and freeness of caking, easiness in decomposition and absorption, high oxidation resistance, stability improvement and long retention time are realized.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a novel compound fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers are referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods contain one or several nutrient elements needed for the growth of crops. They are also called inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, and compound fertilizers. With the development of modern agriculture, the use of chemical fertilizers has increased year by year. With the increase of chemical fertilizers, the soil has gradually become more acidic and alkaline, and the effect of clumping is obvious. When it comes, it will greatly accelerate the loss of nutrients. Contents of the invention [0003] The objective of the present invention is to provide a kind of novel compound fertilizer and p...
