Abstract

The invention relates to the technical field of fruit industry, in particular to a branch net covering technology for preventing diseases and insect pests of a fruit tree. The adopted net bag is a cylindrical net bag with the diameter of 0.3 to 1.5m; the net bag is made of plastic nylon net with the density of 50 to 80 meshes; the net bag is moderate in hardness; according to the length of fruit tree branches, the net bag with the length of 0.3 to 5m is selected and is used for covering fruit branches together with fruits on the fruit branches; when the operation of net covering is performed, the tips of the branches are downwards covered, and small lateral branches are straightened in the net bag; after the branche are covered, two ends of the net bag are tied and sealed by using ropes. The branch net covering technology disclosed by the invention can be used for preventing all diseases and insect pests, mainly used for preventing fruit flies, is suitable for all fruit trees such as cherry, peach, grape and banana and can be also used for preventing the condition that fruits rot as fruit flies spawn on the fruits; the branch net covering technology has the advantages of convenience and simpleness in use, remarkable preventing effect, no environmental pollution and no food pollution.

Description

A kind of branch cover network technology preventing fruit tree diseases and pests

Technical field

The present invention relates to fruit industry technical field, particularly relate to a kind of branch cover network technology preventing fruit tree diseases and pests.

Background technology

In recent years, the harm of fruit bat to fruit is increasing, traditional therapeutic scheme is sprayed insecticide to fruit tree and to fruit bagging, carries out spray medicine result for the treatment of thoroughly, and give fruit bagging to fruit tree, engineering is larger, cost is higher, and sack is airtight, stuffy, produce illumination deficiency to fruit, fruit color degree and particle size grow poor; In addition, bagging fruit easily causes mould to rot, and bagging easily causes shedding phenomenon opportunity too early; For cherry tree, ovum generally produces subcutaneous at cherry fruit by fruit bat before and after cherry expands, and along with the maturation gradually of cherry, ovum starts to suck pulp, causes cherry to rot rapidly; Report that the larva of fruit bat is high protein although have, most people is the large cherry including drosophila larvae beyond affordability still; And cherry is once infection has had fruit bat, its reproduction speed is rapid: generally have worm's ovum or larva from discovery cherry fruit, the fruit of full wafer cherry orchard all will be infected by fruit bat at about 3 days; And infected cherry fruit became again and all rots in one week, lose huge to orchard worker, particularly middle-late ripening variety, No kernels or seeds are gathered, as in a year of scarcity especially.If all cherry trees are not all sprayed insecticide, the infection again of fruit bat can be very rapid; Now cherry is also not suitable for spraying insecticide to the picking season, and medicament residue is to healthy unsuitable; Although orchard worker also takes the method for the method and greenhouse gardening cherry of plucking cherry in advance to avoid loss in recent years, cherry is plucked under underdone state, and its mouthfeel and sugariness are all very poor, also thoroughly cannot solve the harm of fruit bat; And greenhouse gardening, significantly increase planting cost, and the growth of manual intervention fruit tree, cause the various situation such as fruit sweetness, granularity undesirable; If booth meets with the extreme disasters weather such as tempest, booth is very easily torn and is damaged, and causes immeasurable loss.There are trend in advance the breeding of fruit bat in recent years and the time of generation fruit evil, and fruit bat endangers this problem and thoroughly do not solve, and will produce destructive impact to fruit industry such as large cherry.

Summary of the invention

Object of the present invention just there is provided a kind of branch cover network technology preventing fruit tree diseases and pests, by carrying out the process of local sleeve net to the fruit branch with fruit, the infection of fruit bat can be stoped rapidly, effective minimizing to be laid eggs the underproduction caused in fruit because of fruit bat, reduce pesticide pollution, safe and effective, be applicable to the multiple fruit trees such as cherry, peach, grape, banana.

The technical solution adopted for the present invention to solve the technical problems is: a kind of branch cover network technology preventing fruit tree diseases and pests, employing mesh bag diameter is the tubular mesh bag of 0.3-1.5m, mesh bag material is plasticity nylon wire, and the density of nylon wire is 50-80 order, and mesh bag is neither too hard, nor too soft; According to the length of fruit tree, select length to be 0.3-5m mesh bag, entangle fruit branch together with the fruit entirety on fruit branch, during cover net, toward trapping net from the tip of a branch of branch, little side shoot will be made in order in mesh bag; After cover net, the two ends rope tying of mesh bag is tamping; It is suitable that mesh bag size is selected: mesh bag diameter is too little, affects fruit tree ventilation and penetrating light, and daylight is easily burnt cherry and leaf; Mesh bag diameter is too large, and when blowing, mesh bag easily rubs cherry and leaf, waste material.

Further, the mesh bag of mesh bag diameter 0.3-0.4m is enclosed within the withe bar of uniaxial extension; The mesh bag that mesh bag diameter is greater than 0.4m is enclosed within the branch with little side shoot; The mesh bag that mesh bag diameter is greater than more than 1m is enclosed within the larger branch of little tree head or is enclosed within the more branch of side shoot.

Use the cover net time, according to cherry morning, noon and afternoon ripe kind, expand at cherry fruit and overlap net the best the last week.

The invention has the beneficial effects as follows, a kind of branch cover network technology preventing fruit tree diseases and pests, can prevent various damage by disease and insect, mainly prevent fruit bat; Be applicable to the multiple fruit trees such as cherry, peach, grape, banana, simple and easy to use, preventive effect is remarkable, non-environmental-pollution, without food pollution, prevents the fruit bat fruit caused of laying eggs on fruit to rot, saves the number of times of spraying insecticide, decrease labour intensity.

Embodiment

Prevent a branch cover network technology for fruit tree diseases and pests, employing mesh bag diameter is the tubular mesh bag of 0.35m, and mesh bag material is plasticity nylon wire, and the density of net is 60 orders, and mesh bag is neither too hard, nor too soft, does not make because mesh bag is too soft net wall touch fruit, affects preventive effect; Also not because mesh bag is too hard, cause to operating difficulties during fruit tree cover net; According to the length of fruit tree, select length to be 0.5m mesh bag, fruit branch is entangled together with the fruit entirety on fruit branch; During cover net, toward trapping net from the tip of a branch of branch, little side shoot will be made in order in mesh bag; After cover net, the two ends rope tying of mesh bag is tamping; It is suitable that mesh bag size is selected: mesh bag diameter is too little, affects fruit tree ventilation and penetrating light, and daylight is easily burnt cherry and leaf; Mesh bag diameter is too large, and when blowing, mesh bag easily rubs cherry and leaf, waste material.

Further, mesh bag diameter is the withe bar that the mesh bag of 0.3-0.4m is enclosed within uniaxial extension; The mesh bag that mesh bag diameter is greater than 0.4m is enclosed within the branch with little side shoot; The mesh bag that diameter is greater than more than 1m is enclosed within the larger branch of little tree head or is enclosed within the more branch of side shoot.

Above-mentioned detailed description of carrying out with reference to the branch cover network technology of embodiment to prevention fruit tree diseases and pests; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under general plotting of the present invention and amendment, should belong within protection scope of the present invention.
