Plain weaving 0.8*0.8mm 2-3%UV White Insect Mesh Netting For Crop Cover
How to choose the right mesh
Insect nets are a new type of agricultural cover material. It uses
high-quality polyethylene as raw materials, adds anti-aging,
anti-ultraviolet and other chemical auxiliaries, and is made by
drawing and weaving. It resembles window screening and has the
characteristics of tensile strength, water resistance, heat
resistance, corrosion resistance, non-toxic and tasteless, etc.
Proper storage life of up to 3-5 years.
What are the aspects to consider when choosing an insect protection
network?
Select the appropriate specification. The specifications of the
organic vegetable insecticide net include the width, aperture, wire
diameter, and color. In particular, attention should be paid to the
aperture; if the mesh is large, the desired insect repellent effect
will not be achieved; if the mesh is small, the shading will be
excessive and the growth of the crop will be adversely affected. At
present, the suitable mesh is 20-32 mesh, wire diameter 0.18 mm,
width 1.2-3.6 meters, white. If you need to strengthen the shading
effect, you can use black insect nets. Silver-gray insect nets are
better at avoiding embarrassment.
Points to note when using insect nets:
Soil disinfection and chemical weeding before covering the insect
nets are important supporting measures. Be sure to kill the
bacteria and pests that remain in the soil before covering.
Insect nets should be compacted around the perimeter to prevent
pests from sneaking into spawning. When a small shed is covered and
cultivated, the sheds should be higher than the crops to prevent
the leaves from clinging to the insect nets. The pests lay eggs on
the leaves.
Timely humidification and cooling. At higher temperatures, the
temperature and ground temperature in the network are about 1°C
higher than those outside the network, which has a certain impact
on the production of organic vegetables. Therefore, in the
high-temperature season of July-August, the number of water supply
can be increased and the humidity in the net can be maintained to
increase the temperature and reduce the humidity.
In addition to the advantages of shading nets, the Insect Insect
Prevention Network is the most important feature of its ability to
prevent insects and disease, significantly reduce the amount of
pesticides used, is a key technology for pollution-free vegetables,
is a simple, scientific and effective pest control measures.
