Problems solved by technology

[0002] The existing agricultural fertilizers have the following disadvantages: 1. Long-term use will damage the soil and make it harden; 2. The quality of agricultural products is low. Due to the use of chemical fertilizers and pesticides, the taste and quality of agricultural products are significantly reduced, and the quality is obviously lower than that of green products that only use farmyard manure. ; 3. The nutrition is single, the fertility will decrease after long-term use, the utilization rate is low, and the cost will increase

Abstract

The invention relates to a compound fertilizer containing low and medium concentration nitrogen phosphorus potassium humic acid, relating to the agricultural fertilizer field. The prior agricultural fertilizer has the following disadvantages that (1) when used for a long time, the prior agricultural fertilizer can destroy soil and cause soil hardening; (2) the quality of agricultural products is low, due to the application of chemical fertilizer and pesticide, both taste and quality of agricultural products are decreased significantly and the quality is inferior to that of green products which only adopt farmyard manure; and (3) the prior agricultural fertilizer has single nutrition and causes fertility decline, low utilization rate and higher cost when used for a long time. Through the ammoniation of the humic acid by ammonium carbonate, the compound fertilizer containing low and medium concentration nitrogen phosphorus potassium humic acid is prepared according to the proportion of 8 to 14 portions of nitrogen, 8 to 12 portions of phosphorus, 5 to 8 portions of potassium and 15 to 25 portions of aminated humic acid; moreover, the compound fertilizer has the advantages that the compound fertilizer can improve soil, promote crop growth, reinforce the capabilities of crops for resisting plant diseases and insect pests, lodging and drought and improve the quality of agricultural products.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a compound fertilizer containing low and medium concentrations of nitrogen, phosphorus and potassium humic acid. Background technique [0002] The existing agricultural fertilizers have the following disadvantages: 1. Long-term use will damage the soil and make it harden; 2. The quality of agricultural products is low. Due to the use of chemical fertilizers and pesticides, the taste and quality of agricultural products are significantly reduced, and the quality is obviously lower than that of green products that only use farmyard manure. ; 3, the nutrition is single, the long-term use fertility declines, the utilization rate is low, and the cost is increased. [0003] Weathered coal contains organic matter and various trace elements, among which the content of humic acid is very high, some as high as 60%. Humic acid has a good effect on the transformation of saline-alkali...
