Tono
He patu pepeke whānui. Ka taea e ngā nematocides me te mahi whakapūngāwerewere te wawahi i te methyl isothiocyanate, te formaldehyde me te hauwai sulfide i roto i te oneone, ā, he pānga whakamate i ngā nematode rhizoma, ngā nematode kakau me ngā nematode heteroderma. Hei tāpiri, he pānga patu pepeke, patu huakita me te patu otaota, nō reira ka taea hoki te rongoā i ngā harore oneone, ngā pepeke o raro whenua me ngā taru chenopodium, pērā i te rhizoctonia rīwai, ngā pepeke polypteroptera oneone, ngā pīrere kowbeetles, ngā torongū May scarab me ētahi atu. Mā te whakamahi i te 98% matūriki 750 ~ 900g/100m2 oneone onepu, 900 ~ 1050g/100m2 uku hei maimoatanga oneone, hei hora, hei tono awa rānei, ka taea e Chemicalbook te whakahaere i ngā mate nematode huawhenua me te pīnati. Ka taea te whakamahi i te 75% paura makuku 1125g/100m2 hei whakahaere i ngā mate nematode pakiaka rīwai.
He mea whakapūkara oneone, he mea whakamate methyl thioisothiocyanate, ā, hei rongoā hoki i ngā harore, i ngā pepeke me ngā taru whenua, e mōhiotia ana ko te whakangaromanga tere. Ka pirau te hua i roto i te oneone hei hanga i te methylaminomethyl dithiocarbamate, ā, hei hanga anō hoki i te methyl isothiocyanate. Ka taea e ia te whakahaere i ngā nematode me ngā harore oneone, pērā i ngā huakita cataplexy, ngā huakita filarial, te fusarium, me ētahi atu, ā, ka taea hoki te aukati i te tipu o te maha o ngā taru. He pai te pānga whakahaere i te pirau kōwhai miro.
Te tukanga patu huakita
(1) I mua i te whakamahinga o te Dazomet, horoia ngā pakiaka o te hua whakamutunga, ka tāpirihia te tongi taketake e hiahiatia ana mō te hua e whai ake nei.
(2) Me whakarite kia eke te makuku o te oneone ki te 50-60% o te kaha wai o te mara, ki te kore e tutuki i te paerewa, ka taea e koe te wero i te wai ki roto i te mara; 3-5 ngā rā i muri i te whakamakuku, whakamahia te mīhini ki te huri me te wawahi i te oneone kia pai ai te uruhanga o te oneone.
(3) Ina whakamahia te Dazomet, ko te pāmahana tika o te oneone he 12-18 ° C, ā, kaua e iti iho i te 6 ° C te iti rawa.
(4) Whakamahia te 25-40 karamu o te Dazomet mō ia mita pūrua o te whenua. I roto i ēnei, ko te whakamahinga o te kūkamo, te pepa reka, te pepa whare kati kōtuhi he 20-25kg/mu, ko te whakamahinga o te whare kati kōtuhi tōmato he 25-30kg/mu, ā, ko te whakamahinga o te whare kati kōtuhi rōpere he 15-20kg/mu.
(5) Pania te rongoā kia ōrite ki te mata, kātahi ka whakamahi i te parau hurihuri mō te parau hurihuri (ko te hohonutanga he 25-30cm), kia tino pā te pikinga o Dazomet ki te papa parau kia tino whai hua ai. Mena ka tino pāngia te pūtake o te nematode, me 40cm te hohonutanga o te parau hurihuri, ā, me whakamahi te rohe o runga mō te whakamahinga o te rongoā.
(6) Whai muri i te paninga, ka rehuhia te wai ki te mata hei whakaputa i te hau patu huakita (methyl isothiocyanate, formaldehyde me te hauwai sulfide).
(7) Taupokina te kiriata (kaua e iti iho i te 6 te matotoru o te hiraka), kātahi ka whakakīia te kiriata ki te oneone hou, kaua e tukua kia turuturu te hau patu huakita, ā, kia mau tonu te pāmahana o te oneone ki te 10cm i te 20℃, kati te patu huakita mō te 15-20 rā pea (me whakaroa te wā whakapūngao i te pāmahana iti).
(8) Whai muri i te patu huakita, hurahia te kiriata, ka whakamahia te parau hurihuri hei whakapūhau i te oneone, tukuna ngā hau paitini e toe ana i roto i te oneone, me whakapūhau mō te 15 rā pea (ina makariri, ina mākū te rangi, whakaroahia te wā whakapūhau, ina wera, ina maroke te rangi, whakaitihia te wā whakapūhau).
(9) Ka taea te whakatō purapura i muri i te patu huakita.
Te tikanga o te pupuhi o Dazomet
1. He patu huakita oneone whānui-whānui a Dazomet, he pai mō te taiao, he tino whai hua, he iti te paitini, ā, kāore he toenga.
2. Ina whakamahia ki te oneone mākū, ka pirau hei methyl isothiocyanate paitini, formaldehyde me te hauwai sulfide i roto i te oneone, ā, ka horapa tere ki ngā matūriki oneone, ka patu pai i ngā nematode, ngā pathogens, ngā pepeke o raro whenua me ngā purapura taru e pihi ana i roto i te oneone, kia tutuki ai te hua o te horoi i te oneone.
3. He nui te pānga o te pāmahana oneone me te haumākū me te hanganga oneone ki te tono, me nui ake te pāmahana oneone i te 12°C, ko te 12-30°C te mea tino tika, he nui ake te haumākū oneone i te 40% (ka taea e te haumākū ki te pītiti ringa te hanga i tētahi rōpū, ka taea te marara te teitei 1 mita i muri i te hinga ki te whenua hei paerewa).
