Tomato package fertilizer for prevention and control of root-knot nematode and fertilizing method thereof

Abstract

The invention relates to a tomato package fertilizer for prevention and control of root-knot nematode. The tomato package fertilizer includes an alkaline soil conditioner, a paecilomyces lilacinus agent and a humic acid-containing water-soluble fertilizer; the soil conditioner silicon-calcium-potassium-magnesium fertilizer is evenly broadcasted during soil tillage; the paecilomyces lilacinus agentis applied during transplanting; the humic acid-containing water-soluble fertilizer is applied after fixed planting. The package fertilizer is in synergtic mutual promotion, increases the preventioneffect from different views, also improves acidified soil, satisfies the nutrition of the whole growth period of tomato, has no pesticide application, is combined with tomato fertilization and root-knot nematode generation laws, is performed with pure fertilizers, achieves the integrated efficacy of drugs and fertilizers, and is suitable for the whole growth process of the tomato; and in addition,the package fertilizer has the advantages of safety, environmental protection and more prominent continuous application effect, and is of great promotion value in prevention and control of root-knotnematode.

Description

technical field [0001] The invention relates to a tomato set fertilizer for preventing and controlling root-knot nematodes and a fertilization method, belonging to the technical field of agricultural production fertilizers. Background technique [0002] In recent years, with the widespread use of greenhouses, the occurrence of root-knot nematodes has also increased, especially in tomato and other solanaceous fruits. If the control is not in place in time, it will cause a decline in yield and quality, and even plant death. [0003] At present, in the control of root-knot nematodes, chemical control is the main method. The measures include soil fumigation before planting, spraying of pesticide particles when soil is plowed, hole application at planting, and watering with water in the middle of crops and other measures. In terms of soil fumigation, highly toxic pesticides such as chloropicrin and metabam are mainly used. Although the defense effect is outstanding, they are high...

Problems solved by technology

[0010] The technical problems to be solved in the present invention: (1) highly toxic fumigants are used in large quantities, and the soil is easily acidified; (2) highly toxic pesticides can generally only kill the adults of root-knot nematodes, and the effect on the eggs of root-knot nematodes is not high , not only the cost is high but also seriously damages the ecological environment, causing serious safety hazards in the quality of agricultural products, and the control effect is poor; while low-toxic, pollution-free biological pesticides are expensive and slow in effect, and some farmers think that pesticides that cannot be effective immediately after use It is not a good pesticide, but it is a waste of manpower and material resources; (3) the use of chemical agents for years, the resistance is getting worse, and the number of control times is increasing; (4) the control of microbial agents is slow to take effect, and the problem of large insect population density cannot be solved
