ʻupena pale-insecte like me ka puka aniani, me ka ikaika tensile kiʻekiʻe, ka pale ʻana o UV, ke kūpaʻa wela, ka pale ʻana i ka wai, ka pale ʻana i ka corrosion, ke kū ʻana o ka wā kahiko a me nā waiwai ʻē aʻe, ʻaʻohe mea ʻawaʻawa a me ka ʻono ʻole, ʻo ke ola o ka lawelawe ma ke ʻano he 4-6 mau makahiki, a hiki i 10 mau makahiki.ʻAʻole wale ia nā mea maikaʻi o ka uhi ʻana i nā ʻupena, akā ua lanakila pū nō hoʻi i nā hemahema o nā ʻupena pale, a ua kūpono ia i ka hoʻolaha ikaika.

Pono nui e hoʻoukaʻupena hōʻole i nā pepekei loko o nā hale ʻōmaʻomaʻo.Hiki iā ia ke pāʻani i ʻehā mau hana:
1. Pono e kū'ē i nā'ōpala.Ma hope o ka uhi ʻana i ka ʻupena pepeke, hiki iā ia ke pale i nā ʻano mea ʻino like ʻole e like me nā enuhe kāpeti, nā moths diamondback, a me nā aphids.
Ma hope o ka uhi ʻia ʻana o nā huahana mahiʻai me nā ʻupena hōʻoiaʻiʻo, hiki iā ia ke pale maikaʻi i ka pōʻino o nā mea ʻino like ʻole e like me ka ʻanuʻu kāpeti, nā moths diamondback, nā ilo puaʻa kāpeti, Spodoptera litura, nā ʻōpala, nā ʻōpala lau simian, nā aphids a pēlā aku.Wahi a ka ho'āʻo, ʻo ka ʻupena hoʻomalu nalo he 94-97% ka hopena e kūʻē i nā enuhe cabbage cabbage, diamondback moth, cowpea pod borer a me Liriomyza sativa, a me 90% kūʻē i nā aphids.

2. Kāohi i nā maʻi viral.Hiki i ka hoʻouna ʻana i nā maʻi maʻi ke loaʻa i nā hopena pōʻino no ka mahi ʻana i ka hale ʻōmaʻomaʻo, ʻoi aku hoʻi e nā aphids.Eia nō naʻe, ma hope o ka hoʻokomo ʻana i ka ʻupena insect-proof i loko o ka hale ʻōmaʻomaʻo, ua ʻoki ʻia ka hoʻoili ʻana o nā pests, kahi e hōʻemi nui ai i ka ulu ʻana o nā maʻi viral, a ʻo ka hopena hoʻomalu ma kahi o 80%.

3. Hoʻoponopono i ka mahana, ka wela o ka lepo a me ka haʻahaʻa.I ka wā wela, ua uhi ʻia ka hale ʻōmaʻomaʻo me kahi ʻupena keʻokeʻo keʻokeʻo.Hōʻike ka hōʻike: i ka wela o Iulai-ʻAukake, i ka ʻupena keʻokeʻo keʻokeʻo 25-mesh keʻokeʻo, ua like ka mahana i ke kakahiaka a me ke ahiahi me ke kula ākea, a ʻo ka mahana ma kahi o 1 ℃ haʻahaʻa ma mua o ke kahua ākea. i ke awakea o ka la.Mai Malaki a ʻApelila i ka hoʻomaka ʻana o ka pūnāwai, ʻo 1-2 ° C ke kiʻekiʻe o ka mahana i loko o ka hale hoʻoheheʻe i uhi ʻia e ka ʻupena insect-proof ma mua o ke kula ākea, a ʻo ka mahana ma ka honua 5 cm he 0.5-1 ° C kiʻekiʻe aʻe. aia ma ke kula ākea, hiki ke pale pono i ka hau.Eia kekahi, hiki i ka ʻupena hōʻoiaʻiʻo ke pale i kahi hapa o ka wai ua mai ka hāʻule ʻana i loko o ka hale hoʻoheheʻe, hoʻemi i ka haʻahaʻa o ke kula, hoʻemi i ka ulu ʻana o ka maʻi, a hoʻemi i ka hoʻoheheʻe ʻana o ka wai i loko o ka hale kōmaena i nā lā lā.

4. Loaʻa ka hopena malu.I ke kauwela, kiʻekiʻe ka māmā, a na ka mālamalama ikaika e kāohi i ka ulu ʻana o nā mea kanu, ʻoi aku hoʻi i nā mea kanu lau, a hiki i ka ʻupena hōʻoiaʻiʻo ke pāʻani i kekahi kuleana i ka malu.ʻO ka ʻupena 20-22 mesh kala-hina-hina-hōʻoia ma ke ʻano he 20-25%.

5. Kāohi i ka hāʻule hua.Aia ka wā oo o ka hua i ka ua i ke kauwela.Inā hoʻohana ʻia ka ʻupena hōʻoiaʻiʻo e uhi iā ia, e hōʻemi ana ia i ka hāʻule ʻana o ka hua ma muli o ka ua i ka wā oʻo o ka hua.ʻO ka mea nui, ʻo ka hua o ka deragona hua, blueberry, a me ka bayberry i ka wā oʻo e hālāwai me nā makahiki ua, a ʻoi aku ka ʻike o ka hopena o ka hoʻemi ʻana i ka hāʻule ʻana o ka hua..

6. Kāohi i ka hau.Inā loaʻa ka pae hua ʻōpiopio o ka lāʻau hua a me ka pae oʻo o ka hua i ke kau wela haʻahaʻa, maʻalahi ia e hōʻino i ke anu a i ʻole ka pōʻino hau.ʻO ka hoʻohana ʻana i ka uhi ʻupena hōʻoiaʻiʻo ʻaʻole hiki ke hoʻomaikaʻi wale i ka mahana a me ka haʻahaʻa i loko o ka ʻupena, akā hoʻohana pū kekahi i ka hoʻokaʻawale ʻana o ka ʻupena-insect-proof no ka pale ʻana i ka pōʻino hau ma ka ʻili hua.
