Oloa Faʻaaoga Faʻamatalaga

E mafai ona faʻaaogaina le zinc sulfate monateate o le Faifaʻatoʻaga o se faʻalaʻau e mafai ona faʻaolaina i le vai ma siaki ai le eletise i le eletise e faʻaleleia ai le eleele tufatufaina o mea lelei ma faʻalauteleina ai le totoina o faʻatoaga.

E mafai ona faʻaaogaina e puipuia ai faʻamaʻi i fale fualaʻau laʻau. E faʻapea foʻi ona faʻaaoga faʻateleina fetilaisa e faʻaopopo ai fualaʻau metalaʻamu zinc trace elemeni fetilaisa. E mafai ona faʻaaogaina o faʻavae fetilaisa, fetilaisa foliar, ma isi.

1. Faʻaaoga o ni faʻavae fetilaisa:

E mafai ona faʻaaogaina le metalaʻila sima e avea o ni faʻalaʻau faʻavae mo eleele matutu e pei o sana, saito, vavae, toso teine, pateta, soybean, pinati, ma isi mea masani, o le 1-2 kilokalama o le metala paʻepaʻe e faʻaoga i le eka, ma le 10-15 afe mago e faʻaaogaina le eleele lelei. A maeʻa ona palu faʻalelei, faʻapipiʻi tutusa i luga o le eleele, ona suotosina ai lea i le palapala, pe faʻapipiʻi i fasi pepa poʻo ni pu. O fualaʻau aina e faʻaaogaina le 2 i le 4 kilokalama o le zinc sulfate i le mu.

2. Foliar spray application:

1. Laʻau fualaʻau: spray 3% ~ 5% metala paʻepaʻe sulfate fofo tasi masina ae le i germination i le amataga o le tautotogo, ma le pasī faʻasalaga tatau ona faʻaititia i le 1% ~ 2% ina ua maeʻa germination, pe faʻaaogaina 2% ~ 3% metala paʻepaʻe sulfate fofo mo faaletausaga O lala 1 ~ 2 taimi.

2. Fualaʻau: Foliar sprays faʻaaogaina metala paʻepaʻe sulfate faʻatasi ma le faʻatauaina o le 0,05% i le 0,1%, ma o le aʻafiaga o le faʻasusu i le amataga o le tuputupu aʻe o fualaʻau e sili atu, o taimi taʻitasi vaitau o le 7 aso, faʻaauau le paluina 2 ~ 3 taimi, taʻitasi taimi ile mu Fana fanafana 50 ~ 75 kg o fofo.

3. Faʻaʻofuinaina o fatu:

Faʻafefiloi le metala paʻepaʻe sima i totonu o se fofo ma le faʻasologa o le 0,02% i le 0,05%, ma sasaʻa ia fatu i le tali. O le mea masani, e sili le faʻatofuina o fatu i le tali. O fatu araisa e faʻasusu i le 0.1% zinc sulfate solution. O fatu araisa e muamua faʻasusu i le vai manino mo le 1 itula, ona tuʻuina lea i totonu o le metala paʻepaʻe sulfate. O fatu araisa i le amataga ma le ogatotonu e faʻasusu mo le 48 itula, ae o le tuai o fatu araisa e faʻasusu mo le 24 itula. O fatu fatu ua faʻasusu i le 0.02% ~ 0.05% zinc sulfate solution mo le 6 ~ 8 itula, ona mafai ai lea ona lulu ina ua maeʻa. O fatu saito e faʻasusu i le 0.05% zinc sulfate solution mo le 12 itula, ona mafai ai lea ona lulu ina ua maeʻa ona aveʻesea.

Lona fa, o le faʻaaogaina o laʻau laʻau:

Faʻaaoga le 2 i le 3 kalama o le zinc sulfate i le kilokalama o fatu, faʻapipiʻi ma sina vai, faʻapipiʻi luga o fatu, ma faʻafefeteina a o palu. O le vai e tatau ona faʻaaogaina e palu faʻatasi ai fatu. O fatu e mafai ona lulu ina ua maeʻa ona faʻamago i le paolo.
