一, mikhalidwe ya kuyimitsidwa kouma
Wogulitsa wowuma ndi mtundu wa tinthu tating'onoting'ono. Ndilo chinthu chatsopano cham'badwo chomwe chimaposa mapangidwe ena malinga ndi zomwe zili, ukadaulo, ukadaulo, ndi ukadaulo wapamwamba, ndi ukadaulo wogwiritsira ntchito mutayimitsayi. Kuchita kwake kumapangitsa kuti pakhale chinthu chapamwamba pamadzi omwazika. Chifukwa woyenera kuyimitsidwa ali mu mkhalidwe woyimitsidwa asanayani ndi kutulutsa mawu, amakhala mkhalidwe wa tinthu tating'onoting'ono titapuma ndi kutulutsa mawu; Mukamagwiritsa ntchito, imasungunuka ndi madzi ndikubwerera ku State ya kuyimitsidwa, komanso tinthu tating'ono tokhazikika ndi tinthu tating'onoting'ono ta 1-10 μm zimagwiritsidwa ntchito ngati chovuta pa gawo, chobala ndi gawo lopitilira gawo lopitilira. Pambuyo kuyanika, kumakhala tinthu tokhazikika, ndipo ikagwiritsidwa ntchito ndi madzi, imabwereranso ku dziko loyimitsidwa. Mtundu wake wamkati uli ndi maubwino onse a womulumutsidwa, ndipo mawonekedwe ake mwakuthupi ndi abwino kwambiri. Magwiridwe akewa ndi awa:
1. Amasokoneza mwachangu m'madzi, ali ndi mwayi wabwino komanso kuyimitsidwa. Zimasokonekera nthawi yomweyo m'madzi, imabalalitsa mu 6 s, ndipo mwachangu ndikuyimitsa kuyimitsidwa, popanda kuwuma, ndipo palibe chifukwa chotchinga phokoso.
2. Onjezani madzi ochepa kuti achepetse kuyimitsidwa kwa malonda, komwe kumatha kugwiritsidwa ntchito mwachindunji kwa ndege kapena malo opumira. Kupukutira kocheperako kumatha kuwonjezera luso la masiku 10, ndipo ntchito yothandiza imakhala nthawi yayitali kuposa kutsuka komwe kumakhalapo.
3. Tinthu tating'onoting'ono zamadzimadzi zamadzimadzi ndizabwino kutsatira zokolola pambuyo poti kupopera mbewu mankhwalawa, ndikupanga filimu yoteteza yoteteza; Zowonjezera ndi zotsatsa zabwino zotsatsa, zimatha kukulitsa chotsatsa ndikuthana ndi kukokoloka kwamvula. Nthawi zambiri, nthawi yokhazikika ya fungicides ndi masiku 5, koma atatenga mawonekedwe owuma, nthawi yokhazikika imatha kukulitsidwa mpaka masiku 10-14.
4. Tizilombo tating'onoting'ono tinthu tating'onoting'ono tomwe timakhala omveka bwino, chomwe sichingangotsimikiziranso mankhwalawo, koma onetsetsani kuti mankhwalawa atha kulumikizana ndi mankhwalawo kuti akwaniritse mankhwalawo Zotsatira.
5. Chitetezo chabwino, mosiyana ndi ufa wina wonyowa, tinthu tating'onoting'ono timapanga ndende yapamwamba kwambiri padziko lapansi ndikuyambitsa phytotoxicity. Itha kugwiritsidwa ntchito ngakhale nthawi yamaluwa, monga 80% sulfure df. Chifukwa cha kugwiritsa ntchito njira yapamwamba iyi, imatha kusewera mokwanira ndi zabwino za malonda omwe amagwiritsidwa ntchito ndikugwiritsa ntchito ntchito. Itha kugwiritsidwa ntchito kuposa kuyimitsidwa kwa sulfure ndi sulfure ufa. Pofuna kupewa komanso kuchiza matenda a powdery mildew komanso zovulaza zovulaza, kuchuluka kwa mbewu ndikochepa koma zotsatira zake ndi zabwino kwambiri.
6. Mapangidwe otetezeka komanso achilengedwe, osagwiritsa ntchito ma sol sol sol, sadzayambitsa matenda osokoneza bongo, palibe fumbi, lotetezeka kwa ogwiritsa ntchito a phytotootoxicity oyambitsidwa ndi oyenda.
7. Palibe fumbi, osamamatira ku thumba la matsamba, lomwe limagwiritsidwa ntchito mokwanira, komanso zotetezeka kwa wothandizira komanso malo oyandikana nawo.
8.
9. Pali njira ziwiri zogwiritsira ntchito kuyimitsidwa: imodzi yomwe imagwiritsidwa ntchito kwambiri, mankhwalawa amasungunulidwa ndi madzi (pakuyimitsidwa) kenako kuwaza pamitengo ndi masamba; Wina ndikusakanikirana chopindika chowuma ndi dothi ndikufalikira (monga paddy kumunda wa Herdicides).
二. Mfundo zabwino za wothandizidwa wowuma
Pali zinthu ziwiri zofunika kuyimitsidwa; Wina ndi kugwiritsa ntchito utsi wamafuta a spinoution, mankhwalawa amapezeka mwachindunji atachotsa madzi ndi kuwaza; Mkati mwa chakudya cha DF ndi chopanda kanthu, chaching'ono, yunifolomu, yunifolomu la pellet ndi mainchesi a pellet a 50-200 μm, zomwe ndizocheperako kuposa zomwe zimapezeka ndi njira zina zamagetsi. Zogulitsa za DF ili ndi nthawi yochepa yopanda madzi, ndipo nthawi zambiri imabalalitsidwa ndi mtambo. Nthawi zambiri zimatha kusungunuka mkati mwa 10 s kuti apange kuyimitsidwa kwa tinthu toyambira. Mlingo woyimitsidwa ndi wokwera, ndipo zizindikiro zake zosiyanasiyana ndizabwino kuposa njira zina zopumira. Zogulitsa.
