Kugwiritsa Ntchito Zowongolera Kukula kwa Zomera Kupititsa patsogolo Kukolola kwa Selari ndi Ubwino

Selari pakali pano ikufunika kwambiri, zomwe zimapangitsa kuti kulima kwa udzu winawake kuchuluke. Nanga alimi a udzu winawake angatani kuti azikolola bwino komanso azikolola bwino?


Izi 5 zowongolera kukula kwa mbewu zitha kukulitsa zokolola za udzu winawake ndi mtundu:

1. Triacontanol:
Mukayika, perekani njira ya 0.5 mg/L ya Triacontanol pamlingo wa malita 50 pa ekala, kupopera mbewu mankhwalawa kamodzi pa masiku 10 aliwonse kwa 3-4. Siyani kupopera mbewu mankhwalawa milungu iwiri musanakolole. Njirayi imathandizira kukula kwa mbewu, imachulukitsa zokolola, komanso imakulitsa bwino. Kupaka Triacontanol masiku 15-20 kukolola ndikofunikira kuti zokolola zichuluke. Mukamagwiritsa ntchito Triacontanol m'nyengo yozizira, chitanipo kanthu kuti mukhalebe kutentha kuti muwonjezere zokolola.

2. Brassinolide (BRs)
Panthawi yolima udzu winawake, kupopera mbewu mankhwalawa ndi 0.01 mg/L yankho la brassinolide kumatha kukulitsa kutalika kwa mbewu ya udzu winawake ndi 5% -12%, kulemera kwa 8% -15%, ndi chlorophyll ndi 0.55% -2.81%, zomwe zimapangitsa masamba obiriwira, onyezimira. Utsi wachiwiri wa foliar patatsala masiku 10 kukolola ukhoza kupititsa patsogolo mphamvu ya udzu winawake komanso kukana kudwala, zomwe zimapangitsa kuti zikhale zoyenera kusungidwa ndi kunyamula.

3. Gibberellic Acid (GA3):
Masabata awiri kapena atatu musanayambe kukolola udzu winawake, thirirani ndi 20-50 mg/L Gibberellic Acid njira 1-2, pogwiritsa ntchito 40-50 malita a yankho pa ekala nthawi iliyonse. Njirayi imathandizira kuzizira kwa udzu winawake, imachepetsa mtundu wa masamba, imathandizira kukula, imakulitsa tsinde ndi masamba, imatalikitsa ma petioles odyedwa, imachepetsa cellulose, ndikuwonjezera zokolola pafupifupi 20%, kukwaniritsa cholinga chokolola koyambirira. Dziwani kuti kuchuluka kwa Gibberellic Acid sikuyenera kukhala kokwera kwambiri popopera mbewu mankhwalawa kuti musapangitse mbewu kukhala zoonda komanso zazitali. Pakadutsa masiku 1-2 mutapopera mankhwala a Gibberellic Acid, ikani feteleza ndi kukolola pa nthawi yoyenera kuteteza kukalamba kwa zomera. Kuonjezera apo, kuthira njere mu njira ya 5 mg/L Gibberellic Acid (20 ml pa vial, kuchepetsedwa mu 4 kg ya madzi) kwa maola 12 kungathandize kumera bwino.

4. Chlormequat Chloride (CCC):
Kupopera mbewu mankhwalawa ndi 4000-8000 mg/L Chlormequat Chloride solution kungalepheretse kuphuka ndi maluwa, kuwongolera bwino.

5. Paclobutrazol (Paclo):
Kuyambira masamba enieni a 4-5, tsitsani masamba ndi 200-500 mg/kg yothetsera masiku 10-15 aliwonse. Njirayi imatha kulimbikitsa kukula kwa mizu, zimayambira, ndi masamba, kukonza photosynthesis, kukulitsa kukana kwa matenda, ndikuwonjezera zokolola ndi 25% -40%.
