Alkaline organic fertilizer and production method thereof

Abstract

The invention relates to an alkaline organic fertilizer prepared from humic acid, manioc vinasse, magnesium oxide and plant ash, and a production method thereof, belonging to the technical field of production of organic fertilizers. The alkaline organic fertilizer comprises 1 part of humic acid of which the organic content is 70-80%, and 0.5-2 parts of 30-50% plant ash of which the pH value is 10-11.5; or 1 part of humic acid, 0.5-0.8 part of manioc vinasse, 0.1-0.3 part of magnesium oxide and 0.8-1.2 parts of plant ash. The production method comprises the following steps: (1) respectively taking humic acid, manioc vinasse, magnesium oxide and plant ash according to parts by weight, and evenly mixing in a mixer to obtain a powder alkaline organic fertilizer; and (2) sending the mixture of humic acid, manioc vinasse, magnesium oxide and plant ash which are proportionally and evenly mixed, into a roller granulator, and granulating to obtain the granular organic fertilizer. The invention has the advantages of scientific and reasonable material proportioning, and simple technique; and the alkaline organic fertilizer can be independently applied, or applied after being mixed with a compound fertilizer, and can effectively inhibit and prevent soil acidification.

Description

1. Technical field [0001] The invention relates to an alkaline organic fertilizer and a production method thereof, belonging to the technical field of organic fertilizer production. 2. Background technology [0002] Due to the widespread use of chemical fertilizers in agricultural production, the amount of farmyard manure and organic fertilizers is less and less, followed by problems such as soil acidification and compaction caused by long-term use of chemical fertilizers in large quantities. Soil acidification not only seriously affects crops. The absorption of soil nutrients will reduce the utilization rate of fertilizers, and will cause nutritional imbalance of crops, cause various physiological diseases, and directly affect the yield and quality of agricultural products. At present, the main way to control soil acidification is to use acidic soil amendments (soil conditioners) for improvement. Acidic soil amendments are strongly alkaline substances and cannot be mixed wi...

[0002] Due to the widespread use of chemical fertilizers in agricultural production, the amount of farmyard manure and organic fertilizers is less and less, followed by problems such as soil acidification and compaction caused by long-term use of chemical fertilizers in large quantities. Soil acidification not only seriously affects crops. The absorption of soil nutrients will reduce the utilization rate of fertilizers, and will cause nutritional imbalance of crops, cause various physiological diseases, and directly affect the yield and quality of agricultural products

At present, the main way to control soil acidification is to use acidic soil amendments (soil conditioners) for improvement. Acidic soil amendments are strongly alkaline substances and cannot be mixed with fertilizers. Therefore, farmers’ acidified soil improvement will increase the input cost. , and increased labor
