1. Physiological tushen shuka shayi

Bishiyoyin shayi suna da halayen haɓakar haɓakar apical. Ci gaban apical na babban tushe yana da sauri, yayin da buds na gefe suna girma a hankali ko sun kasance suna barci. Amfanin apical yana hana haɓakar toho na gefe ko yana hana haɓakar rassan gefe. Ta hanyar pruning don cire babban fa'ida, ana iya cire tasirin inhibitory na saman toho a kan buds na gefe. Yanke itacen shayi na iya rage shekarun ci gaban bishiyar shayi, ta yadda zai dawo da girma da kuzari. Dangane da girmar bishiyar shayi, datse yana karya ma'aunin ilimin halittar jiki tsakanin sassan sama da na karkashin kasa, yana taka rawa wajen karfafa ci gaban kasa. A lokaci guda kuma, girma mai ƙarfi na kambin bishiyar yana samar da ƙarin samfuran assimilation, kuma tushen tsarin zai iya samun ƙarin abubuwan gina jiki, yana haɓaka haɓakar tsarin tushen.

Bugu da ƙari, pruning yana da tasiri mai mahimmanci akan canza yanayin carbon nitrogen da inganta ci gaban gina jiki. Ganyen mai laushi na bishiyar shayi suna da abun ciki mafi girma na nitrogen, yayin da tsoffin ganyen suna da babban abun ciki na carbon. Idan ba a datse rassan saman na dogon lokaci, rassan za su tsufa, carbohydrates za su ƙaru, abun ciki na nitrogen zai ragu, carbon zuwa nitrogen zai yi girma, haɓakar abinci mai gina jiki zai ragu, furanni da 'ya'yan itatuwa za su ƙaru. Yankewa na iya rage girman ci gaban bishiyar shayi, kuma ruwa da wadataccen abinci da tushen ke sha zai karu sosai. Bayan yanke wasu rassan, rabon carbon zuwa nitrogen na sababbin rassan zai zama ƙanana, wanda zai ƙarfafa ci gaban abinci na sassan da ke sama.

2. Lokacin yankan bishiyar shayi

Yanke bishiyoyin shayi kafin suyi girma a cikin bazara shine lokacin da mafi ƙarancin tasiri akan jikin bishiyar. A wannan lokacin, akwai isassun kayan ajiya a cikin tushen, kuma lokaci ne da yanayin zafi ya tashi a hankali, ruwan sama yana da yawa, kuma girma bishiyoyin shayi ya fi dacewa.
