Problems solved by technology

Potatoes have a wide planting area and a large market demand. In the process of planting potatoes, there are many times of topdressing, unreasonable fertilizer components, low fertilizer utilization rate, and long-term application of fertilizers can easily cause soil compaction, and at the same time lead to deterioration of the soil environment, seriously affecting the sustainable development of agriculture in our country

Abstract

The invention discloses a slow-release fertilizer for potatoes. The slow-release fertilizer for potatoes contains the following raw materials in parts by weight: fermented cow dung, charcoal, biogas residues, polypeptide urea, ammonium nitrate, calcium superphosphate, calcium magnesium phosphate, potassium sulfate, potassium nitrate, modified attapulgite, lime powder, vermiculite powder, citric acid, tartaric acid, sodium humate, gibberellins, brassinolide, xylitol residues, sesame shells and artemisia vulgaris powder. The slow-release fertilizer for potatoes disclosed by the invention is applied as a base fertilizer which is durable in fertilizer efficiency, free of topdressing, reasonable in formula and high in utilization ratio. After application, soil can be fertilized, the physical and chemical properties of the soil can be effectively improved, the soil is hard to harden, the output and quality of potatoes are improved, and sustained development of agriculture of China is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a slow-release fertilizer for potatoes. Background technique [0002] Potato, a perennial herb belonging to the family Solanaceae, has edible tubers and is the fourth most important food crop in the world, second only to wheat, rice and corn. Efficacy such as detumescence. Potatoes have a wide planting area and a large market demand. In the process of planting potatoes, there are many times of topdressing, unreasonable fertilizer components, low fertilizer utilization rate, and long-term application of fertilizers can easily cause soil compaction, and at the same time lead to deterioration of the soil environment, seriously affecting sustainable development of agriculture in our country. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a slow-release fertilizer fo...
