Kodwa-ke, imithi yokubulala izinambuzane esetshenziswa endaweni engaphandle kanye nemithi yokubulala izinambuzane ehloselwe...Funda kabanzi -
Ukuqhathaniswa kwemiphumela yezinto eziphilayo ezibangelwa amagciwane kanye ne-gibberellic acid ekukhuleni kwe-stevia kanye nokukhiqizwa kwe-steviol glycoside ngokulawula izakhi zayo zofuzo.
Ezolimo ziwumthombo obaluleke kakhulu ezimakethe zomhlaba, futhi izinhlelo zemvelo zibhekene nezinselele eziningi. Ukusetshenziswa komhlaba wonke komanyolo wamakhemikhali kuyakhula futhi kudlala indima ebalulekile ekuvuneni kwezitshalo1. Kodwa-ke, izitshalo ezikhuliswe ngale ndlela azinaso isikhathi esanele sokukhula nokuvuthwa...Funda kabanzi -
Izindlela ze-sodium ezine-chlorophenoxyacetic acid kanye nezinyathelo zokuphepha zokusetshenziswa kuma-melon, izithelo nemifino
Luhlobo lwe-hormone yokukhula, engakhuthaza ukukhula, ivimbele ukwakheka kwesendlalelo sokuhlukaniswa, futhi ikhuthaze ukubekwa kwezithelo zayo futhi uhlobo lokulawula ukukhula kwezitshalo. Ingabangela i-parthenocarpy. Ngemva kokusetshenziswa, iphephile kune-2, 4-D futhi akulula ukukhiqiza umonakalo wemithi. Ingamunca...Funda kabanzi -
Yiluphi uhlobo lwesinambuzane esingalawulwa yi-abamectin+chlorbenzuron nokuthi singalusebenzisa kanjani?
