Problems solved by technology

Pesticides will produce residual toxic residues. In order to increase production, chemical fertilizers will be used excessively. Excessive use of pesticides and chemical fertilizers will lead to damage to the soil aggregate structure, soil compaction, soil acidification, soil weakening, soil poisoning, soil ecological imbalance, and biodiversity loss. destroy

Embodiment 1

[0025] The insecticidal additive for water-soluble fertilizer that can kill root-knot nematode of citrus in the present embodiment 1 is used to kill root-knot nematode of citrus, including the following raw materials in parts by weight: 10 parts of marigold extract; 2 parts of neem root extract Concentration is 100 parts of concentrated molasses element of 51%.

Embodiment 2

[0027] The water-soluble fertilizer insecticidal additive capable of killing citrus root-knot nematode in Example 2 includes the following raw materials in parts by weight: 20 parts of marigold extract; 10 parts of neem root extract; 140 parts of concentrated molasses.

Embodiment 3

[0029] The water-soluble fertilizer insecticidal additive capable of killing citrus root-knot nematode in Example 3 includes the following raw materials in parts by weight: 15 parts of marigold extract; 5 parts of neem root extract; 120 parts of concentrated molasses.

[0030] Among the insecticidal additives for water-soluble fertilizers that can kill root-knot nematodes of citrus root-knot nematodes in the above-mentioned Examples 1 to 3, the marigold extract and the neem root extract can be commercially available or self-made. Concentrated molasses is a commercially available product.

[0031] The method of homemade marigold extract and neem root extract is as follows: put marigold into 3-6 times the amount of water, heat and extract, filter to obtain filtrate and filter residue; then squeeze the filter residue to obtain juice; Mix with squeezed juice to obtain a marigold extract with a mass concentration of 20%-30%; put the dried neem root or fresh neem root into 3-6 times...

Abstract

The invention provides an insecticide additive for a water-soluble fertilizer capable of killing citrus root-knot nematode disease, a water-soluble fertilizer and a preparation and using method thereof. The insecticide additive is prepared from a marigold extracting solution, a neem root extracting solution and concentrated sodium cyclamate. Due to the combination of the marigold extracting solution and the sodium cyclamate, reproduction of fungi can be promoted, and the fungi can restrain root-knot nematode; the neem root extracting solution has the insecticidal action, and due to the combination, root-knot nematodes can be effectively killed. The water-soluble fertilizer comprises the insecticide additive and a water-soluble fertilizer base material. The mass of the insecticide additive accounts for 55-85% the mass of the water-soluble fertilizer. The preferential water-soluble fertilizer base material is prepared from boric acid, zinc sulfate, urea and monopotassium phosphate, the photosynthesis of crops can be accelerated, root development is promoted, flower bud differentiation is performed in advance, fruit retention and fruit expansion are performed, and coloring and sweet addition are achieved. The invention provides a preparation and using method of the water-soluble fertilizer. During usage, annular cavity root irrigation is performed after the water-soluble fertilizer is diluted.

Description

technical field [0001] The invention relates to the technical field of agricultural water-soluble fertilizers, in particular to an insecticidal additive for water-soluble fertilizers capable of killing citrus root-knot nematodes, a water-soluble fertilizer capable of killing citrus root-knot nematodes, and a preparation method and application method thereof. Background technique [0002] Root-knot nematodes harm vegetables, fruits, and food crops. The aboveground part of the damaged plant grows short and slow, with abnormal leaf color, few results, low yield, and even premature death of the plant. In order to kill root-knot nematodes, chemical pesticides need to be applied. Pesticides will produce residual toxic residues. In order to increase production, chemical fertilizers will be used excessively. Excessive use of pesticides and chemical fertilizers will lead to damage to the soil aggregate structure, soil compaction, soil acidification, soil weakening, soil poisoning, s...
