A kind of mango special bagging that translucency is strong
Technical field
The present invention relates to planting fruit trees technical fields, and in particular to a kind of mango special bagging that translucency is strong.
Background technique
My area belongs to subtropical monsoon climate, and rain, thermal resource are abundant, rain heat same season, since rain, thermal resource are abundant, also band
Carry out pest and disease damage very much, brings biggish harm to mango production, it is total that the loss caused by causing harm every year because of disease pest accounts for fruit
30% or more of yield, does not pay attention to the prevention and treatment of disease pest slightly such as, and some is even caused to lose and be received.Though part can be kept with medical treatment
Yield, but dosage and number are too many, and increase the residual quantity of pesticide.Solve at present this contradictory best approach be exactly into
Row bagging is cultivated.
Mango bagging has the advantages that fruit is encroached in infection, propagation and insect that can prevent germ etc.;Prevent sky
Gas harmful substance and Acid Rain Pollution fruit;Prevent intense light irradiation ultraviolet ray burn fruit surface;It reduces fruit and other materials is mutual
Frictionally damage fruit face;Pesticide spray number is reduced, avoids pesticide from contacting with fruit, reduces persticide residue;For the fruit of breeding time
It is real to build excellent environment, improve coloring, increase pericarp wax, improve the finish and gloss in fruit face.
Currently, the material of mango bagging mainly has white non-woven fabric fruit bag, ventilative plastic film bag, nylon net bag, paper bag etc..Make
With it is most be paper bag.And the kinds such as red ivory, love text, red apple awns need certain illumination to meet color during the growth process
Requirement.In the prior art, general to carry out excision bagging, heavy workload using 10 days or so before receiving.
Summary of the invention
The technical issues of the present invention overcomes in the prior art, bagging translucency is poor, is not able to satisfy mango lighting requirements, mentions
For a kind of mango special bagging that translucency is strong.

Using effect:
1, the mango special bagging of 1~embodiment of embodiment 3 and 1~control group of control group 5 is applied to mango bagging, implements
1~embodiment of example 3, the recyclable continuous use of mango special bagging 3 years of 2~control group of control group 5 it is all intact, it is prolonged
It is durable.The mango bagging of control group 1 only can be used 1 year.
2, the mango special bagging of 1~embodiment of embodiment 3 and 1~control group of control group 5 is given to red ivory mango set
For bag to picking, the long spot rate of mango, rotting rate, disease pest torture rate, color such as the following table 1.
Table 1
As shown in Table 1, the common bagging of 1~embodiment of mango special bagging embodiment 3 of the invention compared to control group 1
The long spot rate of mango, rotting rate, disease pest torture that rate is low, illustrate that mango special bagging of the invention has the anti-evil effect of preferable disease pest
The translucency of fruit, bagging of the invention is better than common paper bag translucency, and without removing bagging in advance, mango is also with color point
It is bright, the gorgeous color of color.1~embodiment of embodiment 3 compared to control group 2 coated with drug layer without containing anti-fog properties resin,
The coated with drug layer of fatty glyceride, p-methyl benzenesulfonic acid, control group 3 does not contain alanine, polyvinyl alcohol, phthalic acid two
Monooctyl ester, coated with drug layer performance of the invention is more stable, good permeability, drug it is inclusion it is good, can consolidate be bonded in chitin
Fibrous layer, insect-pest anti-mold effect are more preferable.Nanometer two of the 1~embodiment of embodiment 3 compared to the mango special bagging of control group 4
Titania coating does not contain molybdenum oxide, the nanometer titanium dioxide coating of 5 mango special bagging of control group without containing polysorbate60 and
N-butanol, after control group 4,5 bagging of control group, mango color and disease pest harm, long spot situation is all poorer than the present invention.The present invention
The translucency of nanometer titanium dioxide coating, fastness, stability, light is improved after nanometer titanium dioxide coating addition molybdenum oxide to urge
Change performance, the improvement of translucency can make mango color more preferable, and photocatalytic is good, and restraining and sterilizing bacteria effect is good.Nano-silica of the present invention
After changing titanium coating addition polysorbate60 and n-butanol, nanometer titanium dioxide coating stability is high, and transparency enhancing is conducive to light
According to the color of mango is good.
Above description is the detailed description for the present invention preferably possible embodiments, but embodiment is not limited to this hair
Bright patent claim, it is all the present invention suggested by technical spirit under completed same changes or modifications change, should all belong to
In the covered the scope of the patents of the present invention.
