1. Ho hlaolela lipeo tse matla ka raese: Nako e molemo ka ho fetisisa ea meriana bakeng sa raese ke lekhasi le le leng, nako ea pelo e le 'ngoe, e leng matsatsi a 5-7 ka mor'a ho jala.Tekanyo e nepahetseng ea 15% ea phofo e metsi ea paclobutrazol ke lik'hilograma tse 3 ka hektare ka lik'hilograma tse 1500 tsa metsi (ke hore, ligrama tse 200 tsa paclobutrazol ka hektare le lik'hilograma tse 100 tsa metsi).Metsi a tšimong ea lipeo a omisitsoe, 'me lipeo li fafatsoa ka ho lekana.Khokahano ea 15%paclobutrazoleke makhetlo a 500 ho feta mokelikeli (300ppm).Ka mor'a phekolo, tekanyo ea ho lelefatsa semela e ea fokotseha, ho finyella liphello tsa ho laola kholo, ho khothalletsa ho lema, ho thibela ho hlōleha ha lipeo, le ho matlafatsa lipeo.

2. Hlaolela lipeo tse matla mokhahlelong oa makhasi a mararo a peto, sebelisa 600-1200g ea 15% ea phofo e metsi ea paclobutrazol ka hektare, 'me u kenye 900kg ea metsi (100-200Chemicalbookppm) ho fafatsa kutu le makhasi a peto ea chloroll. synthesis, ntlafatsa lebelo la photosynthetic, fokotsa lefu la sclerotinia, matlafatsa ho hanyetsa, eketsa pods le chai.

3. Ho thibela soya ho hola ka potlako ho feta mohato oa pele oa lipalesa, 600-1200 digrama tsa 15% paclobutrazol phofo e metsi ka hektare, 900 kg ea metsi (100-200 ppm), 'me mokelikeli o fafatse kutu le lekhasi la lipeo tsa soya. ho laola bolelele, ho eketsa li-pods le chai.

4. Taolo ea kholo ea koro le ho roala peō ka botebo bo loketseng ba"Paclobutrazole"ho ba le peo e matla, ho lema ho eketsehileng, bophahamo bo fokotsehileng, le ho eketsa chai ho koro.Kopanya ligrama tse 20 tsa 15% ea phofo e metsi ea paclobutrazol le li-kilogram tse 50 tsa peo ea koro (ke hore 60ppm), le sekhahla sa phokotso ea bolelele ba semela se ka bang 5% ho Chemicalbook.E loketse masimo a koro a ho jala kapele ka botebo ba disentimitara tse 2-3, mme e lokela ho sebediswa ha boleng ba peo, ho lokisa mobu, le mongobo o motle.Hona joale, ho jala mochine ho sebelisoa haholo tlhahiso, 'me ho ka ama sekhahla sa ho hlaha ha botebo ba ho jala bo le thata ho bo laola, kahoo ha boa lokela ho e sebelisa.
