Problems solved by technology

[0004] Although crop rotation can prevent the accumulation of harmful substances in the soil and suppress associated diseases, crop rotation is inflexible and difficult to meet the needs of social development
Seed virus detoxification mainly adopts biotechnology measures to remove the virus in the seeds, and obtain virus-free or rarely virus-infected seeds, but the cost of seed production is high, and the re-infection of the virus cannot be avoided
Soil disinfection method refers to spraying a l

Abstract

The invention relates to the technical field of agricultural fertilizers, and in particular relates to a special biological sustained-release fertilizer for tuber crops. The fertilizer comprises the following components in parts by weight: 10-40 parts of compound microbial agent, 50-80 parts of inorganic fertilizer, and 8-10 parts of humic acid. Compared with the prior art, the fertilizer has the advantages that the nutrition proportion is reasonable, and the growing-phase nutrition demand curve of tuber crops can be basically matched with the fertilizer nutrition release curve; the fertilizer contains a high-performance functional strain capable of fixing nitrogen, solubilizing phosphor and solubilizing potassium and an antagonistic strain with a good effect for preventing and controlling soil-borne diseases; the fertilizer utilization can be remarkably improved, environmental pollution can be reduced, and the environment benefit is remarkable; production raw materials of the fertilizer are wide in sources, low in cost and simple in process, and have remarkable economical, social and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for biological slow-release tuber crops. Background technique [0002] Studies have shown that for tuber crops, potassium is the most, nitrogen is the second, and phosphorus is the least. In agricultural production, unreasonable fertilization has a great impact on the yield of tuber crops, especially the partial application of nitrogen fertilizer often results in a substantial reduction in yield. [0003] In recent years, soil-borne diseases of tuber crops have become prominent, mainly including: Fusarium wilt, soft rot, root rot, black root disease, black spot and so on. At present, the main solutions to soil-borne diseases of tuber crops include: reasonable crop rotation, seed detoxification, soil disinfection and fumigation, etc. [0004] Although crop rotation can prevent the accumulation of harmful substances in the soil and suppress a...
