Abstract

The invention discloses a harmless management method for diseases, insects and weeds at a tea tree seedling stage of an organic tea garden and belongs to the technical field of tea leaf ecological production. The method specifically comprises four steps of manually weeding, covering light reflecting weeding films, hanging yellow sticky boards and releasing preying acarus. The method is adopted for production management, chemical herbicides need not to be applied for weeding at the seedling stage of the organic tea garden, chemical pesticides are not used for insect prevention, the labor cost of weeding at the seedling stage can be greatly reduced, no pesticide residue exist, environment pollution does not exist, and the production of organic tea is really realized.

Description

The innoxious management method of the sick Chinese caterpillar fungus of a kind of organic tea garden tea tree Seedling Stage
Technical field
The present invention relates to the innoxious management method of the sick Chinese caterpillar fungus of a kind of organic tea garden tea tree Seedling Stage, belong to Tea Production technical field.
Background technology
Organic farming is a kind of production system of fertilizer, agricultural chemicals, growth regulator and additive for farm animal feed that completely need not or substantially need not be manually synthetic.Production process adopts as much as possible organic waste beyond shift of crops, crops straw, feces of livestock and poultry, legume, green manure, farm and the method for biological pest control to keep soil productivity and arability in maximum feasible region, supplies with a kind of agricultural of crop alimentary prevention and elimination of disease and pests and weeds.Organic farming is more and more subject to people's favor.
Organic tea is a kind of tealeaves that carries out production and processing according to the method for organic farming.In its production process, do not use the material productions such as any artificial synthetic chemical fertilizer, agricultural chemicals, plant growth regulator, chemical food additives completely, and meet IFOAM (LFOAM) standard, through organic (natural) food tissue of awaring a certificate, issue certificate.Organic tea is a kind of tealeaves of pollution-free, pure natural.The organic food of first outlet of awaring a certificate of organic tea Ye Shi China.
Along with raising and the concern to food security of people's living standard, people increase gradually to the consumption figure of " natural, safety, health care " organic tea.But the input existing in juvenile stage tea tree management process in organic tea garden construction is at present many, and output is few, caused harm by disease Chinese caterpillar fungus, poky problem, the organic tea garden management method in young age that therefore need to develop that a set of section emulates the advanced.
Summary of the invention
The object 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 existing in juvenile stage tea tree management process, output is few, endangered by 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 organic tea garden tea tree Seedling Stage, comprises artificial weeding, covers weeding reflective membrane, hangs Yellow sticky trap, discharges 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 weeding reflective membrane, its method is to start to cover weeding reflective membrane apart from tea tree seedling 10-15cm place, and along tea ridge direction laid in parallel, tea tree both sides all cover 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 in tea place, to hang the yellow plate with insect sticker, and quantity is every 666.7 m 2hang 20-30 piece, suspension height, for exceeding tea shoot 20-30 cm, is changed once for 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 tea leaf two spotted spider mite reaches blinds when more than 5, discharges Predatory Mites in field, and release density is every square metre of 10-20 head.The method discharging 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 object of tealeaves organic production;
(2) cover weeding reflective membrane and can stop weed growth, reduce every year tea place weeding 2-3 time, save a large amount of costs of labor; Avoid striving water with young plant in 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 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 reaches the object of protection tea tree.
Adopt the present invention to carry out production management to children's organic tea garden in age; can accelerate 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 tealeaves organic production, save labour turnover, produce significant ecology and economic benefit.
