Kazi ya Chandarua Kinga dhidi ya Wadudu

Mitego ya kuzuia wadudu ni kama skrini ya dirisha, yenye nguvu ya juu ya mkazo, kizuia-ultraviolet, joto, maji, kutu, kuzeeka na mali nyinginezo, zisizo na sumu na zisizo na ladha, maisha ya huduma kwa ujumla ni miaka 4-6, hadi miaka 10. Haina tu faida za wavu wa jua, lakini pia inashinda mapungufu ya wavu wa jua, ambayo inastahili kukuza kwa nguvu.

Utendaji wa chandarua dhidi ya wadudu

1. Frost-ushahidi

Miti ya matunda katika hatua ya matunda machanga na hatua ya kukomaa kwa matunda huwa katika msimu wa kuganda na mwanzo wa msimu wa joto la chini, ambayo inaweza kuathiriwa na uharibifu wa theluji, na kusababisha majeraha ya baridi au majeraha ya kuganda. Maombi ya chandarua cha kuzuia wadudu kufunika sio tu kunasaidia kuongeza halijoto na unyevunyevu kwenye chandarua, lakini pia huzuia kujeruhiwa kwa theluji kwenye uso wa matunda kwa kutenga chandarua dhidi ya wadudu. Ina athari ya wazi sana katika kuzuia jeraha la theluji katika hatua ya matunda ya loquat na jeraha la baridi katika hatua ya matunda ya machungwa kukomaa.

Chandarua cha kuzuia wadudu

2. Kuzuia Magonjwa na wadudu

Baada ya kufunika bustani na vitalu kwa chandarua cha kuzuia wadudu, kutokea na njia za maambukizi ya wadudu wa matunda kama vile aphids, psylla, armyworm wanaonyonya matunda, wadudu walao nyama na nzi wa matunda huzuiwa, ili kufikia lengo la kudhibiti wadudu hawa, hasa wadudu wa aphid, Psylla na wadudu wengine, na kuzuia na kudhibiti ugonjwa wa joka wa machungwa. na kupunguza ugonjwa. Kuenea kwa magonjwa kama vile matunda ya pitaya na nzi wa matunda ya blueberry kuna jukumu muhimu.

3. Kuzuia kushuka kwa matunda

Fruit ripening period is a rainstorm weather in summer. If anti insect netting is used to cover the fruit, it will reduce the fruit drop caused by rainstorm during fruit ripening period, especially in the rainy years of Pitaya fruit, blueberry and bayberry fruit ripening period, which has more obvious effect on reducing fruit drop.

4. Kuboresha Joto na Mwangaza

Covering anti insect netting can reduce light intensity, adjust soil temperature and air temperature and humidity, reduce precipitation in net room, reduce water evaporation in net room, and reduce transpiration of leaves. After covering anti insect netting, the relative humidity of air was higher than that of the control, and the humidity was the highest in rainy days, but the difference was the smallest and the increase was the lowest. With the increase of relative humidity in the net chamber, the transpiration of fruit trees like citrus leaves can be reduced. Water affects fruit quality development through precipitation and air relative humidity, which is more conducive to fruit growth and development, and fruit quality is good.
