40 Mesh Green Insect Mesh Netting For Prevent Wind Pollination
Insect net coverage form
1. Covering of greenhouses Insect protection nets are directly
covered on large scaffolds and compacted with earth or brick. Leave
the main door uncovered for easy access.
2. Small arch cover covered with bamboo or steel curved arched shed
inserted in Daejeon, the insect net covering the arch, after the
water poured directly on the Internet, until the harvest does not
open the net, the implementation of closed cover.
3. Horizontal Shed Covering A field of 2,000 to 3,500 square meters
is covered with insect nets. This form saves net yarns and net
racks and is easy to operate.
The use of insect nets to cover quick-growing leafy vegetables can
prevent pests without pesticides, thereby greatly reducing
pesticide residues in vegetables. In order to achieve a good pest
control effect, the following technical points should be mastered
when covering insect nets.
1. Select the appropriate insect net. Should use 20-32 mesh, wire
diameter 0.18 mm insect net.
2. The height of the arch shed is higher than the height of the
crop. Otherwise, the leaves of the cabbage are close to the
insect-proof nets. The pests such as the flea beetle outside the
net can still feed on the leaves, or the eggs are produced on the
leaves, thus causing harm.
3. The whole growth period is covered. Insect net can shading, but
shading is not much, do not need to cover the night or cover. When
watering, the water can be poured directly on the insect-proof net,
and there will be no inverted seedling phenomenon. Due to the full
coverage, the soil must be disinfected and chemically weeded before
covering the net to kill pathogens and pests that remain in the
soil, and to cut off the spread of pests and weeds.
4. The perimeter of the insect nets is tightly closed to prevent
insects from sneaking into eggs. To be compacted around the
perimeter, tension between the arches should be tightened with a
compression wire to prevent wind blows.
5. Timely increase in temperature and humidity. When the
temperature is particularly high, increase the number of water
supply, maintain the humidity in the net, and lower the
temperature.
6. We can make big width 26m and so on.
