Macadimia nut cultivation insect pest green prevention and control method

Abstract

The invention discloses a macadimia nut cultivation insect pest green prevention and control method. The method comprises the following steps: whitewashing trunks of macadimia nut trees with a specially-made whitewashing agent to prevent longicorn insect pests and termite insect pests, wherein the trunk and the root of the macadimia nut trees can be effectively prevented from being damaged by thelongicorn insect pests and the termite insect pests without chemical pesticide, and the dosage of chemical pesticide is greatly reduced; thinning out macadimia nut branches, wherein air convection canbe increased, the light transmittance is better, insect pests can be effectively reduced, and meanwhile spreading of various diseases can be effectively controlled; installing solar insecticidal lamps for insect killing, wherein physical insect killing can be achieved, the use amount of chemical pesticide is greatly reduced, and environmental protection is achieved; and spraying lime to the ground of the macadimia nut tree planting land from May to August to kill insects and bacteria, wherein the insect killing and bacterium removing effects are remarkable, the use amount of chemical pesticide can be greatly reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pest control of macadamia nut trees, in particular to a green pest control method for macadamia nut cultivation. Background technique [0002] Macadamia is a high-end economic crop in the tropics and subtropics. It has a dense canopy, shallow root system, and is not wind-resistant. It is suitable for planting on hills or flat land below an altitude of 1200m. It requires deep soil and good drainage. Irrigation conditions are available when there is water shortage in the dry season. The highest temperature in summer Generally, it does not exceed 35°C, and the highest temperature in winter is not lower than 15°C. Macadamia nuts are rich in nutrients, with an oil content of 70%-79%, rich in unsaturated fatty acids, rich in protein, calcium, phosphorus, iron, vitamin B1, vitamin B2 and 8 kinds of amino acids necessary for the human body. At the same time, the monounsaturated fatty acid in macadamia nut oil ca...

Problems solved by technology

[0003] At present, the control of macadamia nut diseases and insect pests mainly relies on chemical pesticides, which have the following disadvantages: 1) Long-term irrational application of chemical pesticides has seriously damaged the ecological environment of orchards; 2) The resistance of pests has increased year by year, resulting in an increase in the use of chemical pesticides; 3 ) Increase the cost of pesticides and labor costs for applying pesticides, and increase production costs; 4) The quality of macadamia nuts is reduced, and pesticide residues are too high

[0004] The use of insecticidal lights to control macadamia tree diseases and insect pests does not have the problems of serious chemical pesticide pollution and large chemical pesticide residues, but there are still the following problems: At present, the macadamia tree in Guangxi has not yet reached the goal of contiguous planting. There are many block plantings. When planting small blocks, using insecticidal lamps to kill and control macadamia tree diseases and insect pests will have great disadvantages. Since the use of solar insecticides is the best for large-scale continuous use, if small blocks are not planted, Install insecticidal lights in the planting area to prevent and control macadamia tree diseases and insect pests. The surrounding pests will be affected by the insecticidal lights and will gather in the small planting area. At this time, the pest density in the small planting area will increase geometrically, and the pest density will be higher. Big damage is more serious, and insecticidal lamps cannot completely kill insect pests, which will lead to poor effect of using insecticidal lamps to control macadamia tree diseases and insect pests
