Embodiment 1

[0023] The formulation for reducing the occurrence of root knot nematodes in this embodiment is composed as follows per 1L:

[0024] Trichoderma harzianum spore powder: 30mg

[0025] Maltose: 5g

[0026] Ferrous sulfate: 0.07g

[0027] Magnesium sulfate: 0.8g

[0028] Compound amino acid: 0.5g

[0029] Boric acid: 0.05g

[0030] Ethoxytrisiloxane: 8ml

[0031] Tween 80 with a mass concentration of 98%: 2.0ml

[0032] The balance is water.

[0033] Preparation method: Weigh the components according to the above ratio, first dissolve the Trichoderma harzianum spore powder in water, add Tween 80 with a mass concentration of 98%, and mix the solution uniformly; then combine the solution with ferrous sulfate and magnesium sulfate , Maltose, boric acid, trisiloxane, compound amino acid and water and mix well.

[0034] Trichoderma harzianum spore powder is obtained by inoculating the Trichoderma harzianum strain TH-18 on the spore powder medium, drying it, and pulverizing it. Among them, the Tricho...

Embodiment 2

[0037] The formulation for reducing the occurrence of root knot nematodes in this embodiment is composed as follows per 1L:

[0038] Trichoderma harzianum spore powder: 25mg

[0039] Maltose: 2g

[0040] Ferrous sulfate: 0.05g

[0041] Magnesium sulfate: 0.6g

[0042] Compound amino acid: 0.6g

[0043] Boric acid: 0.04g

[0044] Ethoxytrisiloxane: 8ml

[0045] Tween 80 with a mass concentration of 98%: 1.0ml

[0046] The balance is water.

[0047] The use effect of the preparation of the present invention: in the greenhouse where root-knot nematodes occur, from the melon flowering and fruit setting period, take 200 mL of the preparation, add 10L of clear water and mix evenly, pour it into the melon rhizosphere soil layer, and water 50-100 mL per plant. At the same time irrigate clean water for comparison. After that, watering was performed every 5 days and continuous watering 8 times. Determine the number of root knots, nematode density, and control effect. The effect of reducing root-kn...

Embodiment 3

[0049] The formulation for reducing the occurrence of root knot nematodes in this embodiment is composed as follows per 1L:

[0050] Trichoderma harzianum spore powder: 35mg

[0051] Maltose: 3g

[0052] Ferrous sulfate: 0.06g

[0053] Magnesium sulfate: 0.7g

[0054] Compound amino acid: 0.7g

[0055] Boric acid: 0.06g

[0056] Ethoxytrisiloxane: 8ml

[0057] Tween 80 with a mass concentration of 98%: 1.5ml

[0058] The balance is water.

[0059] The use effect of the preparation of the present invention: In the greenhouse where root-knot nematodes occur, from the flowering and fruit-setting period of cucumbers, take 200 mL of the preparation, add 10L of clear water and mix evenly, and pour it in the cucumber rhizosphere soil layer, and water 50-100 mL per plant. At the same time irrigate clean water for comparison. After that, watering was done every 5d, and watering 6 times continuously. Determine the number of root knots, nematode density, and control effect. The effect of reducing r...

Abstract

The invention relates to a preparation for reducing meloidogyne and a preparation method thereof. Each liter of preparation contains 25 to 35 milligrams of trichoderma harzianum spore powder, 2 to 5 grams of maltose, 0.05 to 0.07 gram of ferrous sulfate, 0.6 to 0.8 gram of magnesium sulfate, 0.6 to 0.7 gram of composite amino acid, 0.04 to 0.06 gram of boric acid, 8 milliliters of ethoxy trisiloxane, 1.0 to 2.0 milliliters of Tween-80, and the balance of water. The preparation is easy to prepare, has the advantages of convenience in use and low cost, and does not have side effect. 40 to 60 percent of root knots of a plant can be remarkably reduced; and after the preparation is used, the resistance of the plant can be remarkably improved, and the consumption of pesticide is reduced. The preparation is suitable for crops such as vegetables, fruit trees, flowers and tea leaves, and is suitable to be popularized and applied in vast rural areas in China.

Description

Technical field [0001] The invention relates to a preparation for reducing the occurrence of root knot nematodes, and also relates to a preparation method of the preparation. Background technique [0002] Meloidogyne spp. is a type of plant pathogen that parasitizes the roots of crops and seriously harms the world's agricultural production. There are more than 3,000 host plants belonging to 114 families, including rice, peanuts, tobacco, tea, fruit trees, vegetables, flowers, medicinal materials, etc. Among them, Solanaceae, Cucurbitaceae, Cruciferae and other plants are particularly affected. Root knot nematode disease mainly damages roots and forms root knots. After the crop roots become ill, the basic functions of the roots are used, and the tissue structure is destroyed, which directly affects the growth of the stems and leaves above the ground, and the leaves are yellowing. At around noon on sunny days, especially in arid climates, the leaves wilt, which looks like insuffic...
