Noi
Nā pesticides ākea. Hiki i nā nematocides me ka hana fumigation ke hoʻopau i ka methyl isothiocyanate, formaldehyde a me ka hydrogen sulfide i loko o ka lepo, a he hopena pepehi i ka rhizoma nematode, ka nematode kumu a me ka heteroderma nematode. Eia kekahi, he hopena insecticidal, bactericidal a me herbicidal kona, no laila hiki iā ia ke mālama i nā fungi lepo, nā mea ʻino ma lalo o ka honua a me nā nāhelehele chenopodium, e like me ka rhizoctonia ʻuala, nā pepeke polypteroptera lepo, nā kowbeetles, nā larvae May scarab a pēlā aku. Me ka hoʻohana ʻana i ka 98% particulate agent 750 ~ 900g/100m2 one lepo, 900 ~ 1050g/100m2 pālolo ma ke ʻano he mālama lepo, hoʻolaha a i ʻole ka hoʻopili ʻana i ka ʻauwaha, hiki iā Chemicalbook ke kāohi i nā maʻi nematode mea kanu a me ka pīnati. Hiki ke hoʻohana ʻia ka 75% pauka pulu 1125g/100m2 e kāohi i ka maʻi nematode aʻa ʻuala.
ʻO ka fumigant lepo, methyl thioisothiocyanate nematocide, a no ka mālama ʻana i nā fungi, nā mea ʻino ma lalo o ka honua a me nā nāhelehele, i ʻike ʻia hoʻi he luku wikiwiki. Hoʻoheheʻe ʻia ka huahana i loko o ka lepo e hana i ka methylaminomethyl dithiocarbamate, a e hana hou i ka methyl isothiocyanate. Hiki iā ia ke kāohi pono i nā nematodes a me nā fungi lepo, e like me ka bacteria cataplexy, filarial bacteria, fusarium, a pēlā aku, a hiki ke kāohi i ka ulu ʻana o nā nāhelehele he nui. Loaʻa iā ia ka hopena kaohi maikaʻi i ka palapū melemele.
Kaʻina hana hoʻomaʻemaʻe
(1) Ma mua o ka hoʻohana ʻana iā Dazomet, e hoʻomaʻemaʻe i nā aʻa o ka mea kanu hope loa, a e hoʻopili i ka mea hoʻomomona kumu e pono ai no ka mea kanu aʻe.
(2) E hōʻoia i ka hiki ʻana o ka wai o ka lepo ma kahi o 50-60% o ka nui o ka wai o ke kula, inā ʻaʻole i kūlike i ke kūlana, hiki iā ʻoe ke hoʻokomo i ka wai i loko o ke kula; 3-5 mau lā ma hope o ka hoʻoinu ʻana, e hoʻohana i ka mīkini e hoʻohuli a wāwahi i ka lepo e hōʻoia i ka permeability o ka lepo.
(3) I ka wā e hoʻohana ai iā Dazomet, ʻo ka mahana kūpono o ka lepo he 12-18 ° C, a ʻaʻole hiki ke emi ma lalo o 6 ° C ka liʻiliʻi loa.
(4) E hoʻohana i 25-40g o Dazomet no ka mika kuea o ka ʻāina. I waena o lākou, ʻo ka hoʻohana ʻana i ka hale kōmahana kukama, pepa ʻono, pepa he 20-25kg/mu, ʻo ka hoʻohana ʻana i ka hale kōmahana tōmato he 25-30kg/mu, a ʻo ka hoʻohana ʻana i ka hale kōmahana ʻōhelopapa he 15-20kg/mu.
(5) E hoʻopili like i ka lāʻau lapaʻau ma luna o ka ʻili, a laila e hoʻohana i ka palau wili no ka mahi ʻai wili (ʻo ka hohonu he 25-30cm), i pili pono ai ka piʻi ʻana o Dazomet me ka papa palau e hoʻokō ai i ka pono kiʻekiʻe loa. Inā loaʻa nui ka nematode knot root, pono ka hohonu o ka mahi ʻai wili he 40cm, a pono e hoʻopili ʻia ka palena kiʻekiʻe o ka hoʻohana ʻana i ka lāʻau lapaʻau.
(6) Ma hope o ka hoʻopili ʻana, pīpī ʻia ka wai ma luna o ka ʻili e hana i ke kinoea disinfection (methyl isothiocyanate, formaldehyde a me hydrogen sulfide).
(7) E uhi i ka ʻili (ʻaʻole e emi ka mānoanoa ma mua o 6 silika), a laila e hoʻopaʻa i ka ʻili me ka lepo hou, mai hoʻokuʻu i ke kinoea disinfection e kahe i waho, a mālama i ka mahana o ka lepo ma 10cm ma 20℃, pani ʻia ka disinfection no kahi o 15-20 mau lā (i ke aniau haʻahaʻa, pono e hoʻolōʻihi ʻia ka manawa fumigation).
(8) Ma hope o ka disinfection, e wehe i ka ʻili, a hoʻohana i ka palau rotary e hoʻoulu i ka lepo, e hoʻokuʻu i nā kinoea ʻawahia i koe i ka lepo, e hoʻoulu pinepine no kahi 15 mau lā (ke anu a pulu ke aniau, e hoʻolōʻihi i ka manawa hoʻoulu, ke wela a maloʻo ke aniau, e hoʻemi i ka manawa hoʻoulu).
(9) Hiki ke lūlū ʻia nā hua ma hope o ka hoʻomaʻemaʻe ʻana.
ʻAno hana o ka boom Dazomet
1. He mea hoʻomaʻemaʻe lepo piha ʻo Dazomet no ke kaiapuni me ka pono kiʻekiʻe, ka ʻawahia haʻahaʻa a ʻaʻohe koena.
2. Ke hoʻopili ʻia i ka lepo pulu, ua hoʻoheheʻe ʻia i loko o ka methyl isothiocyanate ʻawahia, formaldehyde a me ka hydrogen sulfide i loko o ka lepo, a pālahalaha koke i nā ʻāpana lepo, e pepehi pono ana i nā nematodes like ʻole, nā pathogens, nā mea ʻino ma lalo o ka honua a me nā hua nahele germination i loko o ka lepo, i mea e hoʻokō ai i ka hopena o ka hoʻomaʻemaʻe ʻana i ka lepo.
3. Hoʻopilikia nui ʻia ka noi e ka mahana o ka lepo a me ka makū a me ke ʻano o ka lepo, ʻoi aku ka nui o ka mahana o ka lepo ma mua o 12 ° C, ʻo 12-30 ° C ka mea kūpono loa, ʻoi aku ka nui o ka makū o ka lepo ma mua o 40% (hiki i ka makū ke hoʻopili lima i ka lepo ke hana i kahi hui, hiki ke hoʻopuehu ʻia ke kiʻekiʻe o 1 mika ma hope o ka hāʻule ʻana i ka honua ma ke ʻano he maʻamau).
