Below by the beneficial effect for testing adjustable orchard anti-wind net illustratively of the invention.This experiment is in high wind
Under weather, the wind speed and wind-warm syndrome of diverse location inside and outside anti-wind net are measured.
1.1 materials and method
The high orchard windproof net devices of high 6m are set up in Ussurian pear garden north side, simulates and improves setting for orchard nature windbreak
Vertical and protection, research anti-wind net is to reducing air speed influence and the insulation effect to pear tree plant.
The wind speed of diverse location and wind-warm syndrome measure inside and outside anti-wind net：Strong wind weather is selected, uses automatic recording instrument for wind speed (mark
Intelligence GM8902, Guangzhou) measure anti-wind net inside and outside diverse location wind speed change and temperature change.Continuous monitoring 2h, remember per 1min
Record a data.
1.2 results and analysis, as shown in Figure 2.
Fig. 2 is the wind speed dynamic change figure of diverse location inside and outside anti-wind net under strong wind weather.As can be seen that outside anti-wind net
Two test point (netting northern 10m, 2m) velocity wind levels are generally higher than net in each point, wherein it is more northern 2m than net slightly higher to net northern 10m wind speed, say
Bright anti-wind net nearby has iris action to wind speed.Same day wind direction is north wind, nets maximum wind velocity at northern 10m and reaches 11.9m/s, equivalent to
6 grades, there is certain destruction to orchard.After anti-wind net obstructs, the wind speed for netting southern each point substantially slows down, and occurs in net at 2m
Maximum wind velocity be 4.5m/s, net Nan10mChu is 4.8m/s, and net Nan20mChu is 7.2m/s, and net Nan40mChu is 8.6m/s, explanation
In the range of 40m, anti-wind net has iris action to strong wind, and weakens with the increase of distance.Wherein, the effect within southern 20m is netted
Fruit is more notable.
It is to study anti-wind net to the action effect of different wind speed, we have chosen the portion of different velocity wind levels in measurement result
Divided data compares, and is shown in Table 1.As can be seen that the outer wind speed of anti-wind net is different, different distance in corresponding anti-wind net
Wind speed variation tendency is different.When netting outer wind speed in 2.5m/s, anti-wind net choke effect and unobvious；When net outer wind speed 4~
During 6m/s, wind speed is respectively less than the outer wind speed of net within 20m in net, illustrates that anti-wind net protection distance now is 20m.When net exogenous wind
When speed is more than 8m/s, wind speed is respectively less than the outer wind speed of net within 40m in barrier, illustrates that the protective range of anti-wind net alreadys exceed sight
Survey scope, choke positive effect.It follows that the outer wind speed of net is bigger, wind speed reduction amplitude is bigger in barrier, and protection effect is brighter
It is aobvious.When windproof net height is 6m, when extraneous wind speed is 8~10m/s, the wind speed in net in the range of 10m is 4~5m/s, in net
Wind speed in the range of 10~20m is 5~6m/s, and the wind speed in net in the range of 20~40m is 7~8m/s.
Wind speed changes inside and outside the anti-wind net of table 1
Wind-warm syndrome change inside and outside anemobiagraph synchronous recording anti-wind net, is shown in Fig. 3.As a result show, it is similar to wind speed change, prevent
Wind net has been obviously improved the temperature levels in net.It is 6.8 DEG C and 7.0 DEG C to net the mean temperature at northern 10m and 2m, and nets south everywhere
Temperature be followed successively by 8.3 DEG C, 8.1 DEG C, 7.8 DEG C and 7.4 DEG C, maximum lift amplitude is up to 1.5 DEG C.This temperature number determined with winter
According to consistent, illustrate under extreme weather, anti-wind net has obvious warming to act on to orchard.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know basic creation
Property concept, then can make other change and modification to these embodiments.So appended claims be intended to be construed to include it is excellent
Select embodiment and fall into having altered and changing for the scope of the invention.
