Problems solved by technology

[0003] The common insect pests of macadamia nuts are root-knot nematodes. Root-knot nematodes are very harmful to macadamia nuts. Poor sensitivity, many chemical agents are not effective in killing root-knot nematodes, and cannot effectively control root-knot nematodes

Embodiment 1

[0023] A method for preventing and treating root-knot nematodes of macadamia nuts, comprising the following steps:

[0024] (1) Planting site treatment: Before transplanting the macadamia tree, apply 1.8% abamectin EC 1000 times solution to the transplanting site, the application rate is 260kg / mu; after transplanting, water the roots and apply 42% chlorpyrifos EC 2000 times liquid spray root irrigation, application rate is 200ml / plant;

[0025] (2) Crop rotation: rotate evasive plants at 10-15cm around each planting hole; evasive plants refer to shallots or garlic; the sowing time of evasive plants is early spring; specifically, green onions were planted around the planting holes last spring, and green onions were planted around the planting holes this spring. Plant garlic around the planting hole, and plant green onions around the planting hole next spring, and so on; the planting density of the avoiding plants can be the normal planting density of onion and garlic;

Embodiment 2

[0030] A method for preventing and treating root-knot nematodes of macadamia nuts, comprising the following steps:

[0031] (1) Planting site treatment: Before transplanting the macadamia tree, apply 1.8% abamectin EC 1500 times solution to the transplanting site, the application rate is 280kg / mu; after transplanting, water the roots and apply 42% chlorpyrifos EC 2500 times liquid spray root irrigation, application rate is 300ml / plant;

[0032] (2) Crop rotation: rotate evasive plants at 10-15cm around each planting hole; evasive plants refer to shallots or garlic; the sowing time of evasive plants is early spring; specifically, green onions were planted around the planting holes last spring, and green onions were planted around the planting holes this spring. Plant garlic around the planting hole, and plant green onions around the planting hole next spring, and so on; the planting density of the avoiding plants can be the normal planting density of onion and garlic;

Embodiment 3

[0037] A method for preventing and treating root-knot nematodes of macadamia nuts, comprising the following steps:

[0038] (1) Planting site treatment: Before transplanting the macadamia tree, apply 1.8% abamectin EC 1200 times solution to the transplanting site, the application rate is 270kg / mu; after transplanting, water the roots and apply 42% chlorpyrifos EC 2200 times liquid spray root irrigation, application rate is 250ml / plant;

[0039] (2) Crop rotation: rotate evasive plants at 10-15cm around each planting hole; evasive plants refer to shallots or garlic; the sowing time of evasive plants is early spring; specifically, green onions were planted around the planting holes last spring, and green onions were planted around the planting holes this spring. Plant garlic around the planting hole, and plant green onions around the planting hole next spring, and so on; the planting density of the avoiding plants can be the normal planting density of onion and garlic;

Abstract

The invention relates to a macadimia nut root-knot nematode prevention and treatment method. The proportion of soil root-knot nematode accounting for the total number of animals in a soil ecological system is very small, under the continuous cropping condition, the number of the soil root-knot nematode can be increased in an explosive manner, the root-knot nematode frequently occurs in the macadimia nut planting process, the nervous system of the root-knot nematode is not developed, the sensitiveness to chemical agents is poor, and the pesticide effect of most chemical agents for killing the root-knot nematode is poor. By means of the method, a method of combining crop rotation of avoiding plants, biochemical prevention and treatment and traditional Chinese medicine prevention and treatment is adopted to prevent and treat the root-knot nematode, the prevention and treatment effect of the root-knot nematode is extremely good, and the actual production requirement can be met; a traditional Chinese medicine root-knot nematode insect-resist agent is composed of folium artemisiae argyi, camphor tree leaves and sargentodoxae caulis, the root-knot nematode prevention and treatment effect is good, the pesticide effect is lasting, and the actual production requirement can be met; and field management is enhanced, watering and fertilization are conducted in due time, and phosphorus and potassium fertilizers are additionally applied, so that the disease resistance of macadimia nuts can be improved, and the root-knot nematode prevention and treatment effect is better.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for preventing and treating macadamia root-knot nematode. Background technique [0002] Macadamia nut alias: Queensland chestnut, macadamia walnut, macadamia nut, Queensland fruit, is a tree nut native to Australia. Macadamia nuts are evergreen trees and dicotyledonous plants. The crown is tall, with 3 to 4 leaves in whorls, lanceolate, leathery, smooth, with spiny serrations on the edges. Racemes axillary, beige flowers, spherical fruit, leathery, hard endocarp, beige to light brown kernels. It is suitable for growing in mild, humid and windy areas. Among the many dried fruits in the world, macadamia nuts have the highest economic value and have always enjoyed the reputation of "the king of dried fruits". The kernel of macadamia nuts is rich in nutrition (milky white), the exocarp is turquoise, the endocarp is hard and brown, the weight of a single fru...
