The Selection Of Insect - Proof Netting Anit Insect Netting Need To
Pay Attention To Several Problems
At present, many vegetable farmers use 30 mesh, while some
vegetable farmers use 60 mesh.In the meantime, the color that the
insect-proof net that vegetable farmer USES also has black, coffee,
white, argent, blue a few kinds, so choose what kind of
insect-proof net to suit?
First of all, according to the pest to be prevented reasonable
selection of pest control network.For example, in autumn, many
pests begin to move into the shed, especially some moth and
butterfly pests. Because of the large size of these pests,
vegetable farmers can use a relatively small number of insect nets,
such as 30-60 mesh insect nets.However, for those with more weeds
and more whiteflies outside the shelter, the smaller size of the
whiteflies should be considered to prevent them from entering the
holes of the insect control net. It is suggested that vegetable
farmers should use a dense insect control net, such as 40-60
purpose.
Secondly, according to the different needs to choose different
colors of the pest control net.Since the thistle has a strong
tendency to blue, the use of blue insect net is easy to attract the
thistle outside the shed to the surroundings of the greenhouse.
Once the coverage of insect net is not strict, a large number of
thistle will enter the shed and cause harm.And use white
insect-proof net, won't produce this kind of phenomenon inside
large canopy, and cooperate with sunshade net when use, with
choosing white advisable.A silver-gray insect control net also has
a better repellent effect on aphids, black insect control net
shading effect is significant, winter, overcast days is not
suitable for use.You can choose according to the actual use needs.
General spring and autumn season and summer, the temperature is
lower, the light is weaker, it is appropriate to choose white
insect net;Summer in order to take into account shading, cooling,
it is appropriate to choose black or silver gray insect net;In the
area where aphids and viral diseases occur seriously, in order to
drive away aphids and prevent viral diseases, silver grey insect
control nets should be selected.
Again, the selection of insect - proof net, but also pay attention
to check whether the insect - proof net is complete.Some vegetable
farmers reflect many just bought the existence of insect mesh hole
phenomenon, so remind vegetable farmers in the purchase of insect
mesh should be launched, check whether the existence of insect mesh
hole phenomenon.Nevertheless we suggest to be used alone when,
should choose coffee, silvery gray, and when cooperating with
sunshade net use, choice silvery gray, white had better, mesh
chooses 40-60 mesh commonly
