Summary of the invention
The purpose of this invention is to provide the innoxious management method of the sick Chinese caterpillar fungus of a kind of organic tea garden tea tree Seedling Stage, many to solve the input existed in juvenile stage tea tree management process, output is few, endangered by the disease Chinese caterpillar fungus, poky problem.
The technical solution adopted in the present invention is:
The innoxious management method of the sick Chinese caterpillar fungus of a kind of organic tea garden tea tree Seedling Stage, comprise artificial weeding, cover the weeding reflective membrane, hang Yellow sticky trap, discharge 4 steps of Predatory Mites, realizes the innoxious management of the sick Chinese caterpillar fungus of organic tea garden tea tree Seedling Stage.Specific as follows:
(1) artificial weeding, its method is the method that adopts the instruments such as hoe, reaping hook, mower that weed in tea garden is rooted out or cut off, and is controlled at below 2cm to the height of major general weeds.The time of artificial weeding is the 2-3 month in early spring, and weeds start to complete artificial weeding before growth.Must not use or spray any weed killer herbicide or chemical agent carries out weeding.
(2) cover the weeding reflective membrane, its method is to start to cover the weeding reflective membrane at distance tea tree seedling 10-15cm place, and along tea ridge direction laid in parallel, the tea tree both sides all cover the weeding reflective membrane, the soil of leaving a blank that only retains tea tree root both sides 20-30cm, for rich water quality management.
Wherein, weeding reflective membrane used is the double-deck starch composite membrane of a kind of degradable, and bottom is black, not light-permeable; Upper strata is silvery white, can anti-apparent sun light.Ventilative, but waterproof.
(3) hang Yellow sticky trap, its method is to hang the yellow plate with insect sticker in tea place, and quantity is every 666.7 m
2hang the 20-30 piece, suspension height, for exceeding tea shoot 20-30 cm, is changed once in 3 months.
Wherein, specification length and width 20 – 40 cm of Yellow sticky trap used all can.Can be with the infochemical that can lure the insects such as tea tree smaller green leaf hopper, thrips, tea caterpillar, tea geometrid, Aleurocanthus spiniferus, prodenia litura on yellow plate.
(4) discharge Predatory Mites, its method is that the generation quantity the tea leaf two spotted spider mite reaches 5 of blinds when above, discharges Predatory Mites in field, and discharging density is every square metre of 10-20 head.The method discharged is that packed suspension is thrown in.The kind of Predatory Mites used is amblyseius cucumeris oudeman.
The invention has the beneficial effects as follows:
(1) can guarantee not use any chemical pesticide, preserve the ecological environment, reach the purpose of tealeaves organic production;
(2) cover the weeding reflective membrane and can stop weed growth, annual minimizing tea place weeding 2-3 time, save a large amount of costs of labor; Avoid striving water with young plant in the weed growth process and strive fertilizer, affect growth of tea plant.Can improve surface temperature, guarantee the aerial growth temperature of young plant at low temperature season, can make the young plant growth rate improve 15-30%, growth time extends 20-40 days, promotes growth of tea plant simultaneously.Reflective membrane can reflex to sunshine on tea tree, improves light complete utilization effect, the Pests of Tea-Plants such as all right repellent aphid, aleyrodid.
(3) utilization of Yellow sticky trap and Predatory Mites, can effectively control Pests of Tea-Plants by the method for physics and biological control, makes young plant not caused harm by taking food of insect, thereby reach the purpose of protection tea tree.
Adopt the present invention to carry out production management to children's organic tea garden in age; can accelerate the young plant growth rate; effectively avoid young plant to be subject to the serious harm of disease Chinese caterpillar fungus; do not use chemical pesticide; preserve the ecological environment; realize the tealeaves organic production, save labour turnover, produce significant ecology and economic benefit.
Embodiment
Be below specific embodiments of the invention, further illustrate the present invention, but the present invention be not limited only to this.
embodiment 1
The innoxious management method of the sick Chinese caterpillar fungus of a kind of organic tea garden tea tree Seedling Stage, used higher than the terrace-type tea place, hillside more than 800 meters at height above sea level.By 4 step and methods such as artificial weeding, covering weeding reflective membrane, suspension Yellow sticky trap, release Predatory Mites, realize the innoxious management of the sick Chinese caterpillar fungus of organic tea garden tea tree Seedling Stage.Specific as follows:
(1) artificial weeding, its method is to adopt hoe to root out the withered and yellow weeds in tea place, makes young plant on every side without weeds.The time of artificial weeding is late Febuary-early March in early spring, and weeds start to complete artificial weeding before growth.Do not use or spray any weed killer herbicide or chemical agent carries out weeding.
(2) cover the weeding reflective membrane, its method is to start to cover the weeding reflective membrane at distance tea tree seedling 10cm place, and along tea ridge direction laid in parallel, the tea tree both sides all cover the weeding reflective membrane, the soil of leaving a blank that only retains tea tree root both sides 20cm, for rich water quality management.Weeding reflective membrane used is the double-deck starch composite membrane of a kind of degradable, and bottom is black, not light-permeable; Upper strata is silvery white, can anti-apparent sun light.Ventilative, but waterproof.
(3) hang Yellow sticky trap, its method is to hang the yellow plate with insect sticker in tea place, by row, hangs, and every 10 meters distances, hangs 1,666.7 m
2the quantity hung is about 30, and suspension height, for exceeding tea shoot 20 cm, is changed once in 3 months.The specification of Yellow sticky trap used is 30 cm * 30 cm.On yellow plate with the infochemical that can lure the insects such as tea tree smaller green leaf hopper, thrips, tea caterpillar, tea geometrid, Aleurocanthus spiniferus, prodenia litura.
(4) discharge Predatory Mites, its method is that the generation quantity the tea leaf two spotted spider mite reaches 5 of blinds when above, discharges Predatory Mites in field, and discharging density is 10 every square metre.The method discharged is that packed suspension is thrown in.The kind of Predatory Mites used is amblyseius cucumeris oudeman.
(5) result: this method has effectively been controlled the quantity of insect and two spotted spider mite, and the control effect of insect is 89.5%, and the control effect of two spotted spider mite is 85.3%; Also effectively controlled the growth of weeds, the control effect of weeds is 97.0%.
