Example Embodiment

[0038] Example 1:

[0039] A tomato package fertilizer for preventing and controlling root-knot nematodes. The package tomato fertilizer includes alkaline soil conditioner, Paecilomyces lilacinus inoculum and water-soluble fertilizer containing humic acid, alkaline soil conditioner, Paecilomyces lilacinus inoculum, and The mass ratio of humic acid water-soluble fertilizer is 50:3:5. The alkaline soil conditioner is silicon-calcium-potassium-magnesium fertilizer. Silicon-calcium-potassium-magnesium fertilizer contains the following nutrient content by mass percentage: P 2 O 5 -K 2 O5%, SiO 2 20%, CaO 30%, MgO 2%, pH 8-11; Paecilomyces lilacinus spores, calcium, potassium and magnesium fertilizers and mineral source humic acid filter residue, in Paecilomyces lilacinus The number of spores of Paecilomyces lilacinus ≥ 200 million / g, the weight ratio of silicon-calcium-potassium-magnesium fertilizer to mineral source humic acid filter residue is (8-12):1. The nutrient content of the ...

Example Embodiment

[0040] Example 2

[0041] The fertilization method of tomato set fertilizer for preventing and controlling root-knot nematodes described in Example 1. Sprinkle silicon-calcium-potassium-magnesium fertilizer during land preparation and plowing, with a dosage of 75kg per mu, and apply Paecilomyces lilacinus in mixing soil during transplanting. The dosage per mu is 2kg; 30 days after planting, the water-soluble fertilizer containing humic acid is applied by drip irrigation, and the dosage is 7.5L per mu.

Example Embodiment

[0042] Example 3

[0043] The same as the fertilization method described in Example 2, except that:

[0044] Spread silicon-calcium-potassium-magnesium fertilizers during land preparation and plowing, the dosage is 50kg per mu, and when transplanting, apply Paecilomyces lilacinus at a dosage of 3kg per mu; 30 days after planting, drip water-soluble fertilizer containing humic acid, per mu The dosage is 5L.

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...
