Anti Insect Net Bags Price For Agricultural Greenhouse In Malaysia
What should I pay attention to when using insect nets after high temperature shacks:
In the summer heat season, there are many pests, crops such as vegetables in the greenhouse and large arch sheds, and 40 mesh insect nets should be installed for all vents. Especially in order to improve the insect-proof effect, you must pay attention to the following three points after the high temperature shack:
First, cover the insect net immediately after the high temperature shack. At this time, it is still a period of various pests. Before the planting, the sputum residue should be removed from the solar greenhouse. After high temperature suffocation, sterilization, disinfection, and insecticide, immediately cover the insect net to obtain the insect proof effect.
|Characteristics of insect protection net|
|Vegetables covered with insect nets, basically can be exempt from cabbage insects, small cabbage moth, cabbage night moth, twill night moth, yellow crocus jumping beetle, ape leaf insect, aphid and other pests.According to the test, the pest control network for cabbage, diamondback moth, cowpea moth, American spot latent fly control effect is 94--97%, for aphids control effect is 90%.|
|Adjust temperature, soil temperature and humidity||Test shows that the hot July and August, in 25 eyes white insect nets, morning and evening temperatures and open flat, and sunny noon 1 degrees Celsius lower than the open field, early spring 3-4 months, insect nets cover relative higher than outdoor air temperature 1-2 degrees Celsius, 5 cm ground temperature is higher than outdoor 0.5 1 degrees Celsius, can effectively prevent the frost, insect nets room when the rain can reduce indoor rainfall, sunshine can decrease network indoor evaporation.|
|Cover the light||Shading strong light: summer light intensity is large, strong light will inhibit the vegetative growth of vegetable crops, especially leafy vegetables, and insect mesh can play a certain role in shading and strong light direct, 20-22 mesh silver gray insect mesh generally shading rate in 20-25%.|
Secondly, if the high temperature is not covered in time after the shed, the insect net should be installed in the middle of the vegetable cultivation. When installing the insect net, the pests hidden in the shed must be cleaned up in order to obtain a good effect of covering the insect nets and preventing insects.
For example, 2,500 tomatoes are planted in a protected area of 1 mu, assuming mild occurrence of whitefly, with an average of only 10 heads per plant, 25,000 in the whole field, 98% being killed after spraying, and 2% remaining. It is 500 heads. Not to mention that the 500 heads continue to multiply and increase rapidly, that is, they do not breed. With these 500 viruses, the virus can be caused by hundreds or even thousands of tomatoes in the greenhouse. However, as a vegetable farmer's investigation of the insects in the shed, 2,500 tomato plants in 1 mu of sheds contain 500 cigarettes, which are difficult to be found by vegetable growers.
Therefore, the best prevention and treatment method is: when covering the insect-proof net, it is necessary to cooperate with the use of aerosol smoke, and smoke the whitefly, whitefly, mites, etc. in the shed, so that the smoke is completely clean and should be Smoked twice in 10 days. Thus, covering the insect net can achieve a good insect effect.
In addition, the production of green and organic vegetables, it is best to cover the insect nets during the whole growth period of vegetable cultivation. Because the insect net has less shading, it does not need to be exposed after the front cover or the front open back cover or the sun cover is open at night. It is suitable for the mouthwash of vegetables in various periods. In order to receive satisfactory insect control effects, pests are not given the opportunity to invade.
