Pakupedzisira, takashandisa principal component analysis (PCA) kuti tiongorore zvinokonzerwa nemishonga inoshandiswa pamatato (T x Y) uye sitirobheri (T x C).Nhamba idzi dzinoratidza kuti HA kurapwa kwakafanana neacetone mumatato kana mvura mumastrawberries (Mufananidzo 8), zvichiratidza zvishoma zvishoma zvakanaka pakukura kwemiti.Sezvineiwo, iyo yakazara mhedzisiro yeMiZax3 neMiZax5 yakaratidza kugoverwa kwakafanana mumbatatisi (Mufananidzo 8A), nepo kugoverwa kwemakomisheni maviri aya mumastrawberry kwakasiyana (Mufananidzo 8B).Kunyange zvazvo MiZax3 uye MiZax5 yakaratidza kugovera kwakanaka mukukura kwezvirimwa uye goho, PCA ongororo yakaratidza kuti kukura kwemitemo basa rinogonawo kuenderana nemhando dzezvirimwa.
Principal component analysis (PCA) ye (A) mbatatisi (T x Y) uye (B) sitirobheri (T x C).Zvibodzwa zvibodzwa zvemapoka ese.Mutsetse unobatanidza chikamu chimwe nechimwe unotungamira pakati pesumbu.
Muchidimbu, zvichibva pazvidzidzo zvedu zvishanu zvakasununguka zvezvirimwa zviviri zvakakosha uye zvinoenderana nemishumo yedu yapfuura kubva 2020 kusvika 202226, MiZax3 neMiZax5 vari kuvimbisa mirau yekukura kwezvirimwa inogona kuvandudza kukura kwezvirimwa zvezvirimwa zvakasiyana., kusanganisira zviyo, miti yemiti (date palms) nezvirimwa zvemichero yehorticultural26,27.Kunyangwe mamorekuru ari kupfuura mabasa avo ebhayoloji anoramba asina kujeka, ane mukana mukuru wekushandisa mumunda.Zvakanakisa zvezvose, zvichienzaniswa ne humic acid, MiZax inoiswa mune zvidiki zvidiki (micromolar kana milligram level) uye iyo yakanaka mhedzisiro inowedzera kutaurwa.Naizvozvo, isu tinofungidzira iyo MiZax3 dosage pakushandisa (kubva pakushomeka kusvika pakakwirira): 3, 6 kana 12 g/ha uye MiZx5 dosi: 4, 7 kana 13 g/ha, zvichiita kuti maPGR aya abatsire mukuvandudza goho.Zvinogoneka.
