Kunini apho ingqolowa ilungele ukuhlakula?I-90% yabalimi abayazi indlela yokulawula ingqolowa yeJijie

Umbuzo wokuba ingaba kusetyenziswe imichiza yokutshabalalisa ingqolowa (ingakumbi emva kokuhluma, kwaye oku kulandelayo kumela imichiza yokutshabalalisa ukhula emva kokuhluma) iya kuba ngumbangiso minyaka le.Nakwindawo enye, kuya kubakho amazwi ahlukeneyo.Abanye abalimi bacinga ukuba impembelelo yemichiza yokutshabalalisa ukhula kunyaka ophelileyo ilungile, esona sizathu kukuba ukuxhathisa kokhula phambi konyaka kuphantsi;enye inxalenye yabalimi bacinga ukuba umphumo we-herbicides emva konyaka ulungile, isizathu esona sizathu kukuba ulawulo luphelele, ngubani ochanekileyo kwaye ngubani ongalunganga, lo mxholo wenqaku , ndiya kukunika uhlalutyo olucacileyo.
Mandinike impendulo yam kuqala: imichiza yokutshabalalisa ukhula ingasetyenziswa phambi nasemva konyaka, kodwa kuyacetyiswa ukuba wonke umntu ayisebenzise phambi konyaka.
Okwangoku, ngenxa yemozulu eyahlukileyo, iqondo lokushisa kunye nezinye iimeko kwiindawo zokutshala ingqolowa ebusika, kukho ukungafani ngexesha lonyango.Enyanisweni, iyeza linokusetyenziswa unyaka nonyaka.
Nangona kunjalo, ngokukhula kwengqolowa kunye nokhula, isincomo ngokubanzi kukuba sibe ngcono ngaphambili.
Isizathu kukuba:
Okokuqala, ukhula olusandul’ ukuvela kwiminyaka embalwa edlulileyo, kwaye ukuchasana nemichiza yokutshabalalisa ukhula akukho kukhulu kakhulu.
Okwesibini, icokiseke ngakumbi.Emva konyaka, emva kokuvalwa kwengqolowa, ukhula alufanele lubethelwe yi-herbicide, eya kuchaphazela umphumo wokukhula.
Okwesithathu, amanye amayeza okutshabalalisa ukhula aneziphumo ebezingalindelekanga ezithile kwingqolowa.Okuya kuthi kamva kugalelwe isitshizi, isivuno sengqolowa samva siyachaphazeleka.

Izizathu zokucebisa ngemichiza yokutshabalalisa ukhula
1. Isiphumo sokukhula kokhula
Phantsi kweemeko ezifanayo, umphumo wokusetyenziswa kwemichiza yokutshabalalisa ukhula phambi konyaka ungcono noko kunoko emva konyaka.Kukho izizathu ezithathu eziphambili.Enye kukuba ukuxhathisa kokhula kuncinci;Kwiminyaka emithathu eyadlulayo, ngaphambi kokuba ingqolowa ivalwe, ulwelo lomchiza wokutshabalalisa ukhula lwalunokutshizwa ngokuthe ngqo kumphezulu wokhula, kodwa emva kokuba ingqolowa ivaliwe, umyinge wokhula wawuza kuncitshiswa.Kuthiwa umphumo we-weeding wonyaka odlulileyo ungcono kunonyaka emva (kwamanye iimeko zangaphandle).
2. Iindleko zokuhlakula
Ukusuka kuhlalutyo lweendleko zokuhlakula, inani lemichiza yokutshabalalisa ukhula kunyaka ophelileyo lingaphantsi kwelo kunyaka ophelileyo.Imiyalelo yokusetyenziswa iya kufumanisa ukuba isetyenziswe xa ukhula lukwinqanaba le-2-4 leqabunga, oko kukuthi, i-dosage yi-dosage yokhula ngokukhawuleza emva kokuvela kokhula (iminyaka edlulileyo), kwaye emva konyaka omtsha. , ukhula lufikelele kumagqabi angama-5-6., okanye nangaphezulu, ukuba ufuna ukufezekisa umphumo we-weeding, uya kwandisa umthamo ngokufanelekileyo.Iseti yamayeza ibethe i-mu enye yomhlaba ngaphambi konyaka, kunye namanqaku angama-7-8 kuphela emva konyaka, okonyusa ngokungabonakaliyo iindleko zamayeza.
3. Imiba yokhuseleko
Ukhuseleko olukhankanywe apha ikakhulu kukhuseleko lwengqolowa.Wonke umntu mhlawumbi uyazi ukuba inkulu ingqolowa, iphezulu amathuba okuba ne-phytotoxicity emva kokutshiza imichiza yokutshabalalisa ukhula (ngokuthelekiswayo sithetha), kwaye emva kokudibanisa, asinakuphinda sisebenzise imichiza yokutshabalalisa ukhula., Ndibone abanye abalimi, ukuze balinde imozulu efanelekileyo emva konyaka, ingqolowa idityanisiwe kwaye basasebenzisa i-herbicides.Kucingelwa ukuba umphumo wokulinda kukuba ingqolowa ine-phytotoxicity.Ngelixa usebenzisa i-herbicides (i-2-4 isigaba seqabunga lokhula) kwiminyaka embalwa edlulileyo, i-phytotoxicity iya kwenzeka (iqondo lokushisa elingalunganga, indlela yokusebenza, njl. ngexesha lokusetyenziswa), kodwa amathuba ayancipha kakhulu.
4. Ifuthe lesityalo esilandelayo
Eminye imixube yemichiza yengqolowa iya kubangela i-phytotoxicity (iingxaki zentsalela yemichiza yokhula) kwisityalo ngasinye kwisityalo esilandelayo, njengesiphumo seTrisulfuron kumandongomane.Akukhuthazwa ukutyala amandongomane, njengoko kunokwenzeka ukuba kubangele i-phytotoxicity, kwaye i-herbicide efanayo ne-Trisulfuron-methyl, ukuba isetyenziswe kunyaka ophelileyo, iya kunciphisa kakhulu impembelelo kwizityalo ezilandelayo, okanye ingenzeki, kwaye kukho ezongezelelweyo 1- 2 iinyanga ukuba umchiza ukubola.
Emva kokuthetha malunga nokuba kutheni ukhethe ukusebenzisa imichiza yokutshabalalisa ingqolowa kunyaka ophelileyo, makhe sithethe malunga nezilumkiso ezithile xa usebenzisa imichiza yokutshabalalisa ukhula (nokuba kuphambi okanye emva konyaka)

Okwesine, ukusetyenziswa kwemichiza yokutshabalalisa ingqolowa
1. Xa utshiza i-herbicides, iqondo lokushisa akufanele libe liphantsi kakhulu, kwaye uqinisekise ukuba ukushisa ngexesha lokutshiza kungaphezulu kwe-10 degrees (umahluko weqondo lokushisa mkhulu, kwaye iqondo lokushisa ekuseni linokusetyenziswa).
2. Xa utshiza i-herbicides, kucetyiswa ukuba ukhethe imozulu yelanga.Emva kwentsimbi ye-10:00 emini nangaphambi kweye-16:00 emva kwemini, musa ukuyisebenzisa kwimozulu enomoya.
3. Xa utshiza umchiza wengqolowa, xuba ulwelo ngokulinganayo, ungaphinde utshize okanye uphose isitshizi.
Kwiminyaka yakutshanje, ukuvela kwengqolowa yasendle kuye kwanda ngakumbi nangakumbi, kwaye ingqolowa yasendle esisoloko sisithi yahlulahlulwe yaba yibrome, wild oat, nebuckwheat.Ngenxa yokuba kaninzi asikwazi ukuxelela ukuba luhlobo luni lwengqolowa yasendle, iyeza liphosakele, ukuze kubekho ingqolowa yasendle eninzi, echaphazela isivuno sengqolowa.
Ngaba ifanelekile ukubetha ingqolowa yasendle ngoku kwintsimi yengqolowa?Ndikholelwa ukuba abalimi nabasebenzisi kwiindawo ezininzi baxhalabile ngale ngxaki, kwaye kulo nyaka, kukho ingqolowa yasendle eninzi kumasimi engqolowa kunakwiminyaka edlulileyo.Ukongezelela, ingqolowa yasendle ayilula ukuyilawula, kwaye abalimi banenkxalabo yokuba iya kuchaphazela imveliso yengqolowa kunyaka ozayo.
