Amazambane, ukolweni, irayisi, kanye nommbila kwaziwa njengezitshalo ezine ezibalulekile zokudla emhlabeni, futhi zisesikhundleni esibalulekile ekuthuthukisweni komnotho wezolimo waseChina.Amazambane, abizwa nangokuthi amazambane, ayimifino evamile ekuphileni kwethu.Zingenziwa zibe izibiliboco eziningi.Ziqukethe ukondleka okuningi kunezinye izithelo nemifino.Zicebile ikakhulukazi isitashi, amaminerali namaprotheni.“Zinama-apula angaphansi komhlaba”.Isihloko.Kodwa ngesikhathi sokutshala amazambane, abalimi bavame ukuhlangana nezinambuzane nezifo ezihlukahlukene, ezithinta kakhulu izinzuzo zokutshala zabalimi.Esikhathini esifudumele nesiswakeme, izinga lokubola kwamaqabunga amazambane liphezulu.Ngakho-ke, yiziphi izimpawu zokubola kwamaqabunga amazambane?Indlela yokuvimbela?
Izimpawu eziyingozi Zilimaza kakhulu amaqabunga, iningi lawo okuyisifo sokuqala emaqabunga aphansi asencane phakathi nezigaba zokukhula.Amaqabunga amazambane atheleleka, aqala eduze nonqenqema lweqabunga noma ichopho, amachashaza ansundu ngokuluhlaza akhiwa esigabeni sokuqala, bese kancane kancane akhule abe amachashaza amakhulu acishe abe yindilinga acishe abe “mpunga-bunsundu amise okwe-V”, anamaphethini endandatho angabonakali. , futhi imiphetho yangaphandle yezindawo ezigulayo ngokuvamile i-Chlorescence futhi iphuzi, futhi ekugcineni amaqabunga aphethwe yi-necrotic futhi ahangukile, futhi ngezinye izikhathi amachashazi ambalwa amnyama angakhiqizwa ezindaweni ezigulayo, okungukuthi, i-conidia ye-pathogen.Kwesinye isikhathi ingathelela iziqu kanye nemivini, yakhe amachashaza ampunga ansundu angamile, futhi kamuva ingaveza amachashaza amancane ansundu engxenyeni enesifo.
Iphethini yezenzeko I-Potato leaf blight ibangelwa ukutheleleka kwesikhunta esingaphelele i-Phoma vulgaris.Le pathogen idlula ubusika emhlabathini ene-sclerotium noma i-hyphae kanye nezicubu ezigulayo, futhi ingadlula ubusika kwezinye izinsalela ze-host.Uma izimo zonyaka olandelayo zifanelekile, amanzi emvula afafaza amagciwane angaphansi komhlaba emaqabunga noma iziqu ukuze abangele ukutheleleka kokuqala.Ngemuva kokuthi lesi sifo senzeke, i-sclerotia noma i-conidia ikhiqizwa engxenyeni enesifo.Ukutheleleka okuphindaphindiwe ngosizo lwamanzi emvula kubangela ukubhebhetheka kwalesi sifo.Ukushisa nomswakama ophezulu kuhambisana nokuvela kanye nokusabalala kwalesi sifo.Lesi sifo siyingozi kakhulu ezindaweni ezinomhlabathi ompofu, ukuphathwa okubanzi, ukutshala ngokweqile, nokukhula kwezitshalo okubuthakathaka.
Izindlela zokuvimbela nokulawula Izinyathelo zezolimo: khetha iziza ezivundile zokutshala, lawula ukuminyana kokutshala okufanele;ukwandisa umanyolo we-organic, futhi usebenzise ngokufanelekile umanyolo we-phosphorus ne-potassium;ukuqinisa ukuphathwa ngesikhathi sokukhula, ukuchelela kanye nokugqoka phezulu ngesikhathi, ukuvimbela ukuguga kwezitshalo ngaphambi kwesikhathi;ngesikhathi emva kokuvuna Khipha imizimba enesifo ensimini bese uyibhubhisa endaweni eyodwa.
Ukulawulwa kwamakhemikhali: ukuvimbela nokwelashwa kwesifutho esigabeni sokuqala sesifo.Esigabeni sokuqala sesifo, ungakhetha ukusebenzisa u-70% we-thiophanate-methyl wettable powder 600 times liquid, noma 70% mancozeb WP 600 times liquid, noma 50% iprodione WP 1200 Uketshezi oluphindaphindayo + 50% impushana emanzi yeDibendazim izikhathi ezingama-500 uketshezi , noma 50% Vincenzolide WP 1500 izikhathi uketshezi + 70% Mancozeb WP 800 uketshezi, noma 560g/L Azoxybacter·Isikhathi 800-1200 izikhathi uketshezi Junqing ejenti yokumisa, 5% chlorothalonil powder 1kg-5kg kacin 2% i-copper hydroxide powder 1kg/mu ingase isetshenziselwe ukutshala ezindaweni ezivikelekile.
