Kushandiswa kweprohexadione calcium mukotoni topping kunonyanya chinangwa chekudzora kukura kwechirimwa, kuumba chimiro chechirimwa chakanaka, uye kuwedzera goho. Maitiro ayo ekuita, akasanganiswa nemaitiro echinyakare topping nzira (manual kana makemikari), zvinonyatsoita optimizes zvinovaka muviri kugoverwa mudonje.
Migumisiro yaro chaiyo inoratidzwa muzvikamu zvinotevera:
1. Kudzivirira kureba kwedzinde uye kukurudzira kukura kwebazi remichero:
Prohexadione calcium inodzivirira zvakanyanya kukura kwehunde huru yekotoni, ichidzora kureba kwechirimwa ichisimudzira kureba uye kuwedzera kwenhamba yematavi emichero. Izvi zvinokonzeresa chimiro chechirimwa chine musoro, kufambisa mhepo, kupinda mukati, uye kukohwa nemichina.
2. Kukurudzira kuendeswa kwekudya kune nhengo dzekubereka:
Nekudzivisa nhanho dzekupedzisira dzegibberellin synthesis, prohexadione calcium inoderedza kushandiswa kwekudya nekukura kwezvinomera (zvakadai sedzinde rakawandisa uye kukura kweshizha), kusimudzira kuendeswa kwezvigadzirwa zvephotosynthetic kunhengo dzekubereka dzakadai sebuds uye mabhoti, nekudaro ichiwedzera huwandu hwemabhori pachirimwa uye goho.
3. Kuwedzera kusagadzikana uye kusagadzikana kwechirwere: Prohexadione calcium inogona kuvandudza kusagadzikana kwemiti yekotoni, kubatsira kuderedza kushushikana kwemuviri kunokonzerwa nekukanda, uye ine humwe hutongi hunoita kune dzimwe zvirwere (zvakadai seshizha nzvimbo).
4. Zvisikwa zvakatipoteredza uye zvishoma zvakasara: Zvichienzaniswa netsika dze triazole retardants (zvakadai se chlormequat chloride), prohexadione calcium inoshatisa nokukurumidza munharaunda, ine hafu yehupenyu hupfupi, uye haina kusara kwehuturu kune zvirimwa zvinotenderera, zvichiita kuti zvive zvakatipoteredza zvinogadzirisa kukura kwemiti.
Zvidzidzo zvakaratidza kuti kushandisa prohexadione calcium mumatanho panguva yekutungira, kutanga maruva, kusati kwakwirisa, uye mushure mepamusoro pematanho edonje kunogona kuwedzera zvakanyanya biomass kuunganidza uye goho. Kurapa ne1950 g/hm² (T3) kwakaratidza mhedzisiro yakasarudzika, kuwedzera bud uye boll biomass neinopfuura 35% zvichienzaniswa nekutonga, pasina zvakanyanya kukanganisa huremu hwebhoro rimwe chete kana lint percent, asi zvakanyanya kuwedzera huwandu hwemabhotoro pachirimwa.
