Abstract

The invention provides a gel base fertilizer special for cold area rice and a preparation method thereof and belongs to the technical field of fertilizers. The gel base fertilizer is prepared from, by weight, 30-90 parts of a nitrogenous fertilizer, 5-25 parts of a phosphatic fertilizer, 1-10 parts of a potash fertilizer, 1-10 parts of a micro element fertilizer, 1-10 parts of citric acid, 1-5 parts of glucose and 1-10 parts of gel powder, and the sum of all the components is 100 parts. According to the gel base fertilizer special for cold area rice and the preparation method thereof, the gel base fertilizer contains total nutritional ingredients required by growth and development in the whole breeding period of rice, utilization efficiency of various nutritional ingredients in raw materials is high, the water gel absorption effect is good, the features that rice roots grow towards fertilizer and actively absorb the nutritional ingredients are utilized, and the rice roots absorb the required nutritional ingredients from gel according to plant growth and yield forming requirements.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a special jelly warehouse fertilizer for rice in cold regions and a preparation method thereof. Background technique [0002] my country's cold regions (Heilongjiang, Liaoning and Jilin) ​​rice areas have become the most important main and dominant rice production areas in my country. With the increase of planting years, the fertility resources of black soil in cold regions in my country have declined sharply, and the amount of fertilizer used in rice regions in cold regions in China has increased. As the amount of fertilizer increases, it in turn accelerates the compaction of paddy soil and the decline of soil quality. According to the characteristics of rice growth and yield formation in cold regions, rice production needs to apply 1 base fertilizer (mainly compound fertilizer and quick-acting nitrogen fertilizer), 2 top dressings (about 5 days after transplanting seedling...
