Description

Technical Field

[0001] This invention belongs to the field of agricultural fertilizer technology, specifically relating to a special composition for the prevention and control of cucumber virus diseases and its application. Background Technology

[0002] Cucumber viral diseases are common, characterized by high incidence, rapid spread, and difficulty in complete eradication. The main types include cucumber mosaic virus (CMV) and tobacco mosaic virus (TMV), which are classified into mosaic type, wrinkled type, and yellow flower type, seriously affecting the yield and quality of cucumbers.

[0003] Under the new development concept of green and ecological production, pesticides used for cucumber virus diseases are gradually being replaced by water-soluble fertilizers. Water-soluble fertilizer technology involves applying four types of micronutrients—silicon, molybdenum, zinc, and copper—to the crop roots via a water-soluble solution, allowing the plant to absorb the nutrients and control viral diseases. Currently, water-soluble fertilizer technology is still in its early stages of development, facing three main limitations: first, the composition is limited, with each fertilizer having a single and varied composition, resulting in significant differences in control effectiveness across different regions and varieties; second, the application method is simple, but its effectiveness is limited; and third, when two or more fertilizers are mixed, the lack of scientific formulation increases costs while reducing efficacy.

[0004] Based on this, the present invention develops a water-soluble compound fertilizer composition specifically for the prevention and control of cucumber virus diseases and its application. Summary of the Invention

[0005] The purpose of this invention is to provide a special composition for the prevention and control of cucumber virus diseases.

[0006] Another object of the present invention is to provide an application of the above combination.

[0007] To achieve this objective, the present invention provides the following technical solution: A composition specifically for the prevention and control of cucumber virus diseases, comprising the following components in parts by weight: Seaweed fertilizer 0.3-0.7g, molybdenum amino acid 0.02-0.04g Urea 1-11, Zinc fertilizer 0.5-1.1 100 ml of cleaning water.

[0008] Furthermore, the cucumber virus disease prevention and control composition preferably includes the following components in parts by weight during the initial stage of cucumber virus disease: seaweed fertilizer: zinc fertilizer: molybdenum amino acid: urea: water = 0.5: 0.8: 0.03: 6: 100.

[0009] The seaweed fertilizer is any one of seaweed oligosaccharides, alginic acid, and seaweed polysaccharides, preferably seaweed oligosaccharides, with a dosage ratio of 0.3-0.7; the zinc fertilizer is EDTA-Zn-15 or zinc sulfate, preferably EDTA-Zn-15, with a dosage ratio of 0.5-1.1; the urea is 46% urea, with a dosage ratio of 1-11; it is widely applicable to the prevention and peak periods of cucumber virus diseases. The adjustment ranges for the seaweed fertilizer concentration during the prevention and peak periods, and the initial period, are ±0.2 (0.3 and 0.7 respectively); ±0.3 (0.5 and 1.1 respectively); ±0.01 (0.02 and 0.04 respectively); and ±5 (1 and 11 respectively).

[0010] The above composition is used for the prevention and control of cucumber virus diseases. When applying it: dissolve the seaweed fertilizer in water at 28-32℃ using a ceramic container; dissolve the zinc fertilizer in water at 20-25℃ using a plastic container; dissolve the molybdenum fertilizer in water at 18-22℃ using a ceramic container; dissolve the urea at room temperature using a ceramic or other container; stir each solution thoroughly; then pour the above four solutions into water in sequence and stir thoroughly.

[0011] The composition of this invention is suitable for immediate preparation and application on the same day. When applied in protected areas, it is applied by drip irrigation at a rate of 100 kg per mu (667 square meters). When applied in open fields, it is applied by flood irrigation through a pipe network at a rate of 150 kg per mu (667 square meters). The composition is applied twice, with an interval of 10-15 days between applications.

[0012] Based on the biological characteristics of cucumber, the plant's growth environment, and the requirements for pollution-free, green, and organic agricultural production, this invention, following a systematic study of the occurrence, infection cycle, and control methods of cucumber viral diseases throughout the entire cucumber growth cycle, proposes a novel comprehensive technology for the prevention, attenuation, and dormancy of viral diseases. This technology can be widely applied to the prevention and control of viral diseases in both direct-seeded and grafted cucumber production. The water-soluble compound fertilizer of this invention contains trace element zinc, which binds with enzymes to participate in metabolic activities such as photosynthesis and respiration, thus attenuating viral activity; trace element molybdenum, which participates in protein synthesis and promotes the stability of physiological functions; seaweed oligosaccharides, which stimulate root development, balance vegetative and reproductive growth, control excessive vegetative growth, promote flower bud differentiation, and improve fruit setting rate and quality; and urea, which maintains the plant's nutritional balance and enhances its resistance. Through the synergistic effect of seaweed fertilizer, zinc fertilizer, molybdenum fertilizer, and urea, it can effectively control cucumber viral diseases. By comprehensively and synergistically addressing the root, leaf, and fruit aspects of cucumber, it improves the cucumber's metabolic function, maintains nutritional balance, enhances disease resistance, and timely controls vector insects, effectively preventing cucumber viral diseases. After applying the water-soluble compound fertilizer of the composition of this invention, the yield and output value of cucumbers are significantly increased, with the yield increasing by 18-22% and the output value increasing by 25%. While generating economic benefits, it also effectively protects the ecological environment.

[0013] In summary, the fertilization process of this invention is simple to operate, highly safe, has low labor intensity and low environmental pollution, and is highly efficient, which can fully meet production needs. Detailed Implementation
