Abstract

The utility model relates to a light reflecting fruit bag which belongs to the technical field of agricultural planting, cultivation and protection. The utility model designs the light reflecting fruit bag which can be used for preventing the day burn disease of young fruits of red globe grape from occurring in a large area in hot weather under strong light irradiation in summer. The light reflecting fruit bag is composed of an outer plastic reflecting film bag and an inner white draining and ventilating paper bag. Through the high-efficiency reflection of the outer bag to direct light, the utility model prevents lots of heat energy from entering the inner bag to burn the young fruits. The utility model provides convenient and feasible cultivating and protecting technique for preventing the day burn disease of fruits from occurring.

Description

A kind of reflective fruit bag

Technical field the utility model is a kind of reflective fruit bag, belongs to the agriculture cultivation technology field.

Background technology is red to be carried, and also claims the red earth (Red Globe), is in recent years at the very fast grape variety of China's plantation development.Present China's red carrying of high-quality of producing, fruit ear just puts the fruit bag from the growth of young phase in cultivation management technology, corrodes to reduce pesticide pollution and damage by disease and insect.And fruit is the pericarp delicacy behind bagging, lovely luster.Now the grape bagging that generally uses is generally white, is the individual layer bagging of being made by hydrophobic and ventilative paper preferably.Sometimes also use coloured double-deck papery bagging for apple or other kind fruit.Finding in the red cultivation management of carrying in recent years, under the high temperature in 6～July of growth of young phase (33 ℃～38 ℃) weather, the sun burn evil was taking place very easily ^[1]Particularly through the fruit ear of grape protected by bagging, the fruit grain of (30～40) % fruit ear sunny slope all has the sun burn evil to take place under the high temperature, causes the red quality of carrying to descend and the underproduction.Day burning area easily takes place northern China at present has at the red anti-day burning technology that adopts in the cultivation management of carrying ^[1]: postpone bagging time as far as possible, all fruit bagging directly do not contact direct light, and fruit ear all can have blade to block before the colouring, if any by direct light-struck fruit ear, overlap the fruit bag at the bottom of mouth must all open, and on bag, add the newspaper parasols, prevent that too high the causing of bag interior temperature from day burning.Since China North China, the Northeast June to July hot weather more, illumination is stronger, though take burning measure in above-mentioned anti-day, because of managerial difference, day burning phenomenon is still serious quite a lot of regional red grape garden in.Be badly in need of seeking a kind of new way to solve a day burning problem.

The summary of the invention the purpose of this utility model is a kind of reflective fruit bag of design.This bagging can prevent effectively that high temperature, intense light irradiation from carrying burning of young fruit fruit grain to red, makes under hot weather that the sunny slope fruit ear can normal growth in the fruit bag.The utility model selects for use plastic refective film to make the outer bag of reflective fruit bag, with hydrophobic papery white grapes bagging be that inner bag is formed double-deck reflective grape bagging.By outer bag reflectance coating direct sunlight is carried out the high efficiency reflection, stop a large amount of heat energy to enter inner bag.Temperature is not higher than the outer temperature of bag in the control bag thereby reach, and prevents that the sun burn evil from taking place.

This reflective fruit bag is made up of inner bag [2] and outer bag [1].Inner bag [2] can be the hydrophobic, air-permeability of an all size fruit bag made of paper (prior art), and outer bag [1] is to adopt plastic refective film partly or entirely to wrap up inner bag and make.Outer bag [1] is than inner bag [2] wide (1～4) cm, and outer bag [1] length can be determined by circumstances.But outer bag side integrated bond, all right discontinuous point bonding [3], sack [4] is left in outer bag of top, and ventilative discharge outlet [5] can be left for two jiaos in outer bag of below, and all the other bases are bonding, also can open by end mouth.Outer bag can be made into pocket-like (Fig. 1), also can be made into umbrella (Fig. 2), can also single face be pasted on the one side (Fig. 3) of pocket-like inner bag.This reflective fruit bag also can be removed inner bag [2] with outer bag [1] and use separately.The main effect of outer bag made from plastic refective film is burning day of prevention fruit young fruit, and therefore the difference by specification can be made into grape bagging, Apple Bags, pears bagging and various fruit or vegetables bagging.The utility model compared with prior art advantage is: the fruit bag is modified into the outer bag of plastic refective film by the hydrophobic, air-permeability paper bag.Strengthened the albedo of fruit bag greatly, made fruit inner bag temperature not be higher than temperature, avoided a large amount of heat energy burning of bringing at summer high temperature weather Xiayang light direct beam to the fruit young fruit to direct light.Prevented the generation of large tracts of land (particularly red proposing) sun burn effectively.When autumn fruit grow up when needing colouring fruit Over-bag (plastic refective film) taken and get final product.Embodiment the utility model preferred forms: inner bag: the 25cm * hydrophobic papery grape bagging of 35cm white, outer bag: 27cm * 35cm plastic refective film bagging, form double-deck reflective fruit bag (also can claim reflective double-deck grape bagging), outer bag is except that leaving sack, and all the other sides adopt discontinuous point bonding.Experimental field being located at year after year, serious area, the despot continent in North China, red grape garden, Qinhuangdao take place in a day burning.Spray the insecticidal and antibacterial medicament before the test routinely.Experimental group is with 600 of reflective double-deck grape baggings; 200 of the white hydrophobic papery grape baggings of control group 25cm * 35cm individual layer, the exposed fruit ear of bagging is 200.2002.6.28～2002.7.15 does a bag inside and outside thermometric to experimental group and control group, photometry is strong, and a situation arises for the term day burning, record temperature, illuminance, day burning fringe incidence.Experimental result sees Table 1: table 1
