Kupopera mbewu mankhwalawa 3 mpaka 4 nyengo yonseyo kumatha kuwongolera bwino kuwonongeka kwake, ndipo nthawi yotsalira imakhala pafupifupi 10d.

(2) Kupewa ndi kuchiza apulo tsamba nthata: pamaso kapena pambuyo apulo maluwa, mu siteji wamkulu ndi ngati nthata zimachitika, pamene aliyense tsamba ali pafupifupi 2 nthata, ntchito mankhwala, ndi utsi ndi 10% kirimu 3300 ~ 5000 nthawi madzi. Pankhani ya kuchepa kwa mite pakamwa, nthawi yotsalira inali masiku 24 mpaka 28. Itha kugwiritsidwanso ntchito poyang'anira ochita mgodi wamasamba ndi nthata zofiira pamitengo ina yazipatso.
