Prohexadione calcium bụ onye na-ahụ maka ihe ọkụkụ nke na-akwalite mmụba nke tubers na ihe ọkụkụ dị ka poteto na poteto dị ụtọ, na-eme ka mkpụrụ na mma dịkwuo mma.
Usoro nke ime ihe: Site na igbochi njikọ gibberellin, calcium Prohexadione na-agbaji ikike nke apical, na-ebute oke ị ga na internodes dị mkpụmkpụ, si otú a na-ebelata uto vegetative ma na-eduzi ngwaahịa photosynthetic n'ebe tubers. N'otu oge ahụ, ọ na-abawanye ọdịnaya chlorophyll, na-eme ka arụmọrụ fotoynthetic dịkwuo mma, na-akwalite ntụgharị nke assimilates na tubers, na-amụba nchịkọta ihe akọrọ.
Mmetụta nke ngwa calcium Prohexadione:
Na-akwalite mmụba tuber: Mgbe ngwa ahụ gasịrị, a na-emewanyewanye tuber, na-eme ka ọ dịkwuo otu nha na ụbara mkpụrụ.
Na-eme ka mma dị mma: Mmụba ọdịnaya ihe akọrọ na ndụ nchekwa nke tubers na-eme ka ọnụ ahịa ahịa dị elu.
Na-eme ka mgbakasị ahụ dịkwuo elu: Prohexadione calcium na-akwalite mmepe mgbọrọgwụ, na-egbochi ịka nká, ma nwee mmetụta nchịkwa ụfọdụ na ọrịa ụfọdụ (dị ka nduku mbubreyo blight).
Otu esi eji calcium Prohexadine:
Nhazi na usoro onunu ogwu: Prohexadione calcium na-adịkarị ka 5% effervescent granule ma ọ bụ uzuzu wettable. Maka poteto na poteto dị ụtọ, a na-atụ aro ka iji 20-40 grams nke 5% Prohexadione calcium kwa mu (ihe dị ka hectare 0.067), tinye 1-2 ugboro dabere na ọnọdụ uto.
Key ngwa oge: Ngwa kwesịrị ịmalite site na mmalite ogbo nke tuber guzobe na mmalite nke tuber gbasaa ogbo, mgbe osisi na-dị nnọọ egosi ike ibu, maka ezigbo pụta.
Akpachara anya: Zenarị iji n'okpuru ọnọdụ acid siri ike. Enwere ike ịgwakọta ya na fatịlaịza ndị ọzọ ma ọ bụ ndị na-achịkwa (dị ka DA-6) iji mee ka mmetụta ahụ dịkwuo elu, mana ekwesịrị itinye nlebara anya na itinye uche iji gbochie igbochi oke uto.
