Long-acting compound fertilizer and preparation process thereof

Abstract

The invention provides a long-acting compound fertilizer and a preparation process thereof. The fertilizer is composed of the following chemical fertilizer raw materials: 8% of fulvic acid, 0.7% of magnesium sulfate, 0.7% of ferrous sulfate, 1.2% of zinc sulfate, 1.5% of ammonium sulfate, 0.5% of manganese sulfate, 0.5% of ammonium molybdate, 1.5% of borax, 5% of calcium superphosphate, 20% of polypeptide urea and 20% of potassium sulfate. The invention has the advantages that the fertilizer has the effects of adjusting the too high or too low pH value of soil, resisting salts and alkalis, improving hardened soil, promoting crop growth, improving crop disease resistance, resisting lodging, resisting continuous cropping, resisting plant diseases and insect pests, resisting freezing damage,protecting soil moisture loss, enhancing drought resistance, improving crop yield, improving quality of crops, vegetables and melons and fruits, improving original quality and original flavor of vegetables and melons and fruits, and leading to a long preservation period.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and in particular relates to a long-acting compound fertilizer and a preparation process thereof. Background technique [0002] Compound fertilizer is a compound fertilizer obtained by mixing several chemical fertilizer raw materials together and stirring them to make them fully mixed. There are many types of compound fertilizers on the market, but these compound fertilizers cannot effectively improve the soil compaction caused by a single fertilizer for a long time, cannot effectively adjust the pH of the soil, and cannot improve the production and product quality of crops. It has brought great losses to the harvest of agriculture, and caused certain harm to people's health. For example: the national patent "a long-acting full-element compound fertilizer" (Patent No. 93114588.0) is like this. Modern people's environmental awareness has been enhanced, and the awareness of ad...
