Summer Use Of Greenhouse Anti Insect Net To Pay Attention To Cooling
Effective pest control, high number of greenhouse insect pest control network of the effect is better, summer mosquito disease more, the use of greenhouse insect control network of farmers are more, summer use of greenhouse insect control network to pay attention to cooling, this section small make up for you to introduce the use of greenhouse insect control network in summer to pay attention to cooling.
In order to prevent viral diseases, 60 mesh is installed in the upper and lower air vents of the greenhouse, which can completely stop the pests such as whitefly outside the shed, avoid the viruses and other pathogens outside the shed brought by the pests, and reduce the incidence of vegetables.But this is caused great effect for greenhouse ventilation cooling, even using sun-shade net cool, because of the relative air circulation, temperature is high, the highest temperature is maintained at 35 ℃, those above.
So, vegetable farmers in the installation of 60 mesh insect control net, how should be cool? First of all, for the establishment of 60 mesh insect control net of the greenhouse, vegetable farmers can no longer set the wind shield.Vegetable farmers in the past set up the windscreen, are to avoid the cold wind outside the shed into the greenhouse, to prevent the tomato fruit growing in the shed appear brush skin.
But now the use of high-density insect protection net, insect protection net will form a certain block on the cold air outside the shed, slow down the cold air into the greenhouse of the speed, so that cold air in the process of entering the greenhouse preheating, can also avoid cold air chapped tomato skin.In addition, in the installation of high density insect net in the shed, the wind shield will affect the air flow in the shed, so that the greenhouse ventilation cooling effect is reduced.Therefore, the vegetable farmers should shed the wind.
Secondly, the greenhouse will be placed under the wind to open the maximum.Now the straw curtain on the greenhouse has been removed, the vent at the top of the greenhouse can be opened to the maximum, that is, the vent film can be directly supported to the southern edge of the rear slope of the greenhouse, so as to increase the vent, it can accelerate the exhaust of hot air in the shed.For the air outlet at the front of the greenhouse, the vegetable farmers can directly support the film to the pressure film steel wire at the front of the greenhouse, and increase the amount of cold air into the greenhouse by increasing the vent, so as to accelerate the air flow and reduce the temperature of the greenhouse
