Likhona yini ikhambi ngoba ukhula

Zonke balimi, balimi, basemapulazini abatshali unayo eyodwa isitha ezivamile - ukhula. Lezi zitshalo zikhule yonke indawo, futhi ikakhulukazi lapho akudingekile. Emasimini, amasimu ezithelo nemifino izingadi ukhula bagibele izitshalo, omisiwe futhi inciphisa nemvundo enhlabathini, umswakama eqoqwe nokudla okuvela izitshalo futhi sikwenze kube nzima ukuba ukuvuna. Ngaphezu kwalokho, bahlala Amagciwane ezahlukene kanye izinambuzane, okuyinto evame ukugula nge izitshalo utshalwe ngasemanzini indoda. Kafushane, ukuvimbela ukhula casula wonke nangamandla abo can kuphela umona.

Kodwa isayensi akusho ukulala. Ososayensi baye basungula izindlela ezihlukahlukene ukhula ukusiza ekulweni nabo. Ukhula, yebo, okuzuza esebenza ngemishini. Lokhu ukulima, ezinyantisayo, ukutshalwa, ngisho isandla-Ukuhlakula ukhula. Izazi zezolimo namahlathi ziyasebenza ngokushintshana. Futhi kulezi zindlela isikhathi esithile kungakusiza ukuqeda izitshalo okungafunwa, kodwa hhayi isikhathi eside. Nokho, kukhona izindlela ukuthi kusebenze kakhulu - ke yokubulala ukhula.

Kule ndawo, isayensi seyithuthuke kude. Ngokwesibonelo, cabangela izinkondlo, esebenzisa "Tornado" ukhula. Ngosizo lokhu ukhula kungenziwa alwa ngempumelelo njengoba kungabantu abangaphezulu kuka-150 zama-ukhula zisetshenziswa kanye ngonyaka. Ngemva ukwelashwa nge "Tornado", iningi lawo awaveli ngesikhathi yokukhula lonke. Futhi ukhula yonyaka ukuthi umphumela ukhula ezingu-20 kuya ku-60 ngaphambili baze ungekho proizrastut kusuka imbewu.

Kukhona enye indlela ukhula ngaphansi kwegama "Roundup". Lena izidakamizwa jikelele osithathayo isinyathelo kunoma iyiphi ukhula. Isetshenziselwa cishe kuyo yonke indawo. Ukulungiswa "Roundup" lisetshenziswa njengendlela letindzala ukhula isenzo esiqhubekayo. Futhi aphathwe endaweni oyifunayo ngisho ngaphambi kokuhlwanyela noma, okungenani, ngaphambi ukuvela. Kulokhu, umsebenzi inhlabathi, akabe ifa, futhi izenzo kuphela amahlumela amasha kanye namahlamvu. Ngaphezu kwalokho, lesi sidakamizwa "Roundup" ubhekwa ephephile abantu uma isetshenziswa ulandele iziyalezo ezikuyo.

Futhi uma lokhu weedkiller isicelo ngaphambi yokuhlwanyela, uyoqinisekisa futhi ukubhujiswa okuphelele kwalelizwe ukhula zisetshenziswa kanye ngonyaka, dicotyledonous futhi wokudla. Futhi ukhula "Roundup" kuleli cala uyokwenza emhlabathini komhlaba izingxenye ukhula ngaphandle kwenhlabathi zaderzhivayas. Ngo phansi nje leyo ndawo ilahlekelwa umsebenzi wayo futhi ubola ku izinto zemvelo.

Kukhona futhi indlela ukhula enegama sonorous "Agrokiller". Ngosizo lwawo, ubhubhise futhi ukhula utshani dicotyledonous, zisetshenziswa kanye ngonyaka. Futhi, lesi sidakamizwa "Agrokiller" kusiza ukulwa ukhula nezihlahla. Lokhu ukhula Isidakamizwa jikelele Fighter senzo. Futhi manje akukho izitshalo (ngaphandle transgenic) okuyiwona akunamthelela. Futhi uma sisetshenziswa kahle lokhu ukhula akuyona anobuthi emhlabeni isilwane.

Awu weedkiller "Lapis" yakhelwe ukubhekana cereal ukhula dicotyledonous, yonyaka futhi zisetshenziswa e okutshalwe Solanaceae - utamatisi kanye amazambane. Futhi lokhu ukhula ngoba amazambane notamatisi akuyona nzima. Ingasetshenziselwa for 1-2 izinyanga ngisho nangokwengeziwe ukuvikela ubumsulwa isivuno ukhula. Izidakamizwa "Lapis" singasebenza ngaphambi avele nokhula. Khona-ke ebhubhisa kubo kwi sigaba sokukhula. Futhi, bona zingahlungwa ukhula kakade lihluma. Kulokhu, kusho "Lapis" kudingeka izinsuku 10-20 ukuze awabhubhise.
