2. Nā hana ʻenehana

(1) ʻO ka lipine soya a me ka lipine kulina

Ma ke komohana hema, ua nui ka ua, a he nui nā ʻano nāhelehele, he paʻakikī ke mālama.Kanu ʻia ka kulina ma mua o ka soybeans a me ka hoʻohana ʻana i ka herbicide pono e "pepehi pū ʻia".Ma hope o ka lūlū ʻana i ka kulina, e hoʻohana i ka metolachlor (a i ʻole acetochlor) + thifensulfuron-methyl e hoʻopaʻa i ka lepo.Inā loaʻa nā mauʻu ma ke kula ma mua o ka lūlū ʻana i ka kulina, hiki iā ʻoe ke hoʻohana i ka glufosinate-ammonium spray;ʻAʻole maikaʻi ka hopena hoʻopaʻa lepo Inā makemake ʻia ka mālama ʻana i ka lāʻau a me ka lau lau, nicosulfuron + fluroxypyr (a i ʻole clopyralid, bentazone) hiki ke hoʻohana ʻia no ke kuhikuhi (wahi kanu kulina) kumu a me ka ehu lau ma ka pae lau 3 a 5 ma hope o ke kanu ʻana i ke kulina.

ʻEkolu lā ma mua o ka lūlū ʻana i ka soybean, koho ʻia ka glufosinate no ka hoʻoheheʻe ʻia ʻana ma nā lālani kaʻawale ma ke kula.Ma hope o ka lūlū ʻana a ma mua o nā mea kanu, hoʻopaʻa ʻia ka lepo me nā pesticides e like me metolachlor (a i ʻole acetochlor) + thifensulfuron-methyl.Inā ʻaʻole maikaʻi ka hopena o ka hoʻopaʻa ʻana i ka lepo a koi ʻia ka pīpī ʻana i nā ʻōpala a me nā lau, quizalofop-pp (a i ʻole fluroxyfop-pp kiʻekiʻe, fluazifop-pp, clethodim) + B Carboxyfluorfen (a i ʻole bentazone) i kuhikuhi ʻia (wahi kanu soybean) kumu a lau lau.

(2) Ka lipine soy a me ke kulina

Ma Huanghuaihai, ka waena a me ka haʻahaʻa o ka muliwai Yangtze, a me Northwest China, lulu ʻia nā soybeans a me ka palaoa i ka manawa like, a hoʻohana nui ʻia nā herbicides ma hope o ka lūlū ʻana a me ka hoʻomaʻamaʻa ʻana i ka lepo ma mua o ka hoʻopaʻa ʻana, pono e hoʻopau ʻia i loko o 2 mau lā ma hope o ke kanu ʻana.Hana ʻia ka hoʻopaʻa ʻana o ka lepo ma ka hoʻohana ʻana i ka metolachlor i hoʻomaʻemaʻe ʻia (a i ʻole metolachlor, acetochlor) + fensulfame (a i ʻole thifensulfuron-methyl) a me nā mea hana ʻē aʻe.Ke hoʻopaʻa ʻia ka lepo me nā lāʻau herbicide ma ke kula kahi o ka ʻōpala mua he palaoa, ʻoi aku ka maikaʻi o ka hana ʻana i ka ʻōpala rotary no ka wehe ʻana i ka ʻōpala, hana i ka wai, a laila lūlū a kau i nā pesticides ma mua o ke kanu ʻana;no na kihapai kahi i hoolaha pololei ia ai ka opala palaoa, pono e hoonui i ka inu wai no ka mu, a e hoopili i na pesticides ina hiki.Ma hope o kēlā, wai i ka manawa;ma nā wahi maloʻo a me nā ʻino one e like me ke Komohana Akau, ʻoi aku ka maikaʻi o ka hui ʻana i ka lepo ma hope o ka hoʻohana ʻana i nā herbicides, a me ka wai i ka manawa e ʻae ai nā kūlana.

Inā ʻaʻole maikaʻi ka hopena o ka hoʻopaʻa ʻana i ka lepo a koi ʻia ka mālama ʻana i ka lāʻau a me ka lau, hiki ke hoʻohana ʻia ma ka pae 3-5 lau ma hope o ke kanu ʻana i ka kulina, 2-3 soybeans ma ka pae ʻekolu-lau, a me ka mauʻu ma ka 2-5. pae lau.E like me nā kūlana mauʻu kūloko, hiki ke koho ʻia ke kulina.ʻO Nicosulfuron (a i ʻole oxaflumezone) + bentazone (a i ʻole fluroxypyr), a me nā māla soya e koho i ka quizalofop-p-ethyl (a i ʻole fluroxyfop kiʻekiʻe) + bentazone (a i ʻole fluroxyfen-ethanol) ) ʻO ka hoʻoulu ʻana i ke kumu lāʻau no ka weeding (e hoʻohana i nā pale kino e hoʻokaʻawale ai. kulina a me ka soybeans no ka pulupulu ana).I ka wā ma hope, hiki ke hoʻoneʻe lima ʻia nā nāhelehele paʻakikī.
