Nutritional type water-retention and soil-loosening compound fertilizer and preparation method thereof

Abstract

The invention discloses nutritional type water-retention and soil-loosening compound fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer. The nutritional typewater-retention and soil-loosening compound fertilizer is prepared from the following raw materials in parts by weight: 20-30 parts of cow dung, 5-10 parts of sawdust, 5-10 parts of straw, 0.1-0.3 part of EM beneficial microorganisms, 5-10 parts of wormcast, 10-20 parts of shell powder, 0.05-0.1 part of polyaspartic acid, 3-5 parts of superphosphate, 15-20 parts of potassium chloride and 15-20 parts of urea. By adding the polyaspartic acid, the slow release effect of the polyaspartic acid is utilized, softening of the shell powder is accelerated in the using process of the fertilizer, the fertilizer efficiency wrapped inside the fertilizer is released conveniently and supplied to plants for growing durably and rapidly, the activity of humic acid in the fermentation fertilizer is improvedthrough the polyaspartic acid, the fertilizer can be combined with metal ions in water, nutritional elements are conveyed to crops advantageously, nitrogen, phosphorus, potassium and trace elements are enriched to supplied to the plants, thus the fertilizer is better utilized by the plants, the yield of the crops is increased, the quality of the crops is improved, the soil quality can be improved,and absorption and growth of the plants are facilitated.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutrient-type water-retaining loose soil compound fertilizer and a preparation method thereof. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production. [0003] Due to the increase in the input of chemical fertilizers and the use of a large number of chemical fertilizers and pesticides, the problem of food supply has been solved and the production of food has been increased. However, the use of large amounts of chemical fertilizers has brought about great environmental problems. The utilization rate of fertilizers has decreased, soil compaction, and water retention capacity have decreased. , soil erosion, and further aggravate the deterioration of the soil physical and chemic...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of nutritive water-retaining loose soil compound fertilizer and preparation method thereof, in order to solve the existing compound fertilizer that proposes in the above-mentioned background technology in the process of using, although fertilizer is bigger, but plant growth The absorbed nutrients are limited, and the nutrients of a large amount of fertilizers are lost with the infiltration of water, which cannot promote the growth of plants for a long time. In the general compound fertilizer production process, clay or bentonite is mostly used as a binder, and the effect is not great when the amount is small. If it is too large, the content of active ingredients will be reduced, and it will not be easily dissolved when applied to the soil, which will affect the release of fertilizers. It is not very useful to the soil, and it is not convenient for the repair of the soil itself.
