What you need to know before using insect nets
Insect nets are a new type of material used to prevent vegetable
insects in the field. They can both shave and prevent insects, and
they have a wide range of applications. We need some understanding
of the pest network when we use it. First of all, we have to
understand the coverage period of the insect net. Because of the
holes in the insect-proof nets, there is not much shading, and it
is not necessary to cover them at night in the daytime. It is
better to cover the whole process so that the pests do not have an
opportunity to invade, so as to receive satisfactory results.
Insect-proof net is a new type of cover material, which is made of
polyethylene (PE) as a raw material and is woven and woven to form
a window screen. With high tensile strength, UV resistance, heat
resistance, water resistance, corrosion resistance, aging
resistance and other properties, non-toxic and odorless, the
service life of 3 ~ 5a [1]. In order to study the application
effect of insect nets on small green vegetables, this experiment
was specially conducted. 1 Materials and Methods 1.1 Species of
test materials: Dwarf yellow, sowing volume is 22.5kg/hm2. Insect
nets and control agents: 5% of CPT is produced by the Japan
Petroleum Corporation; 2.5% of deltamethrin EC is imported from
France.
The experimental design pest control test set up five treatments:
(1) 0.45mm (40 mesh) aperture insect nets; (2) 0.6mm (30 mesh)
aperture insect nets; (3) 5% Suppository EC 2000 times; (4) 2.5%
deltamethrin emulsifiable concentrate 2000 times; (5) control.
Repeat 3 times, randomly arranged. The shelter net community was
bent into bamboo sheds, each plot was 7.0m×1.67m, and the ditch
width between the plots was 0.5m.
There is also an insect screen to choose the appropriate aperture
size. We must pay attention to the size of the aperture when
choosing to purchase insect nets. In general, vegetable production
mainly uses 20-32 mesh, which is about 1 to 1.8 meters wide. In
addition, black insect nets can be used. Also understand the
coverage of the insect net. You can use steel bars or bamboo pieces
to be bent into small arches, inserted into the surface of Daejeon,
and then cover the insect nets on the arches. Watering can be
poured directly on the net, and the nets can be uncovered when
harvesting. Fully enclosed coverage.
In addition, horizontal scaffolding can also be used. During the
covering and cultivation process of insect nets, it is best to
apply pollution-free organic fertilizer, select resistant insects,
use biological pesticides, and water sources that are not polluted.
Insect nets should be removed promptly after the end of field use.
Blow dry, wash, roll well. Maximize the service life, reduce the
depreciation cost, and bring more economic benefits
