Ndi zowongolera zakukula kwa zomera zomwe zimagwiritsidwa ntchito pa nyemba zobiriwira?

Mukabzala nyemba zobiriwira, nthawi zambiri mumakumana ndi zovuta zosiyanasiyana, monga momwe nyemba zobiriwira zimakhalira, kapena zimakula mwamphamvu, kapena zimakula pang'onopang'ono, kapena maluwa amagwa, ndi zina zotero. Panthawiyi, kugwiritsa ntchito kwa sayansi kwa owongolera kukula kumatha kusintha kwambiri zinthu, kotero kuti nyemba zitha kuphuka kwambiri ndikuyika nyemba zambiri, potero zimawonjezera zokolola za nyemba zobiriwira.

(1) Kulimbikitsa kukula kwa nyemba zobiriwira
Triacontanol:
Kupopera mbewu mankhwalawa Triacontanol kumatha kukulitsa kuchuluka kwa nyemba zobiriwira. Mukapopera mankhwala a Triacontanol pa nyemba, mulingo wokhazikika ukhoza kuwonjezeka. Makamaka mu kasupe pamene kutentha kochepa kumakhudza kuyika kwa pod, mutatha kugwiritsa ntchito mankhwala oledzeretsa a Triacontanol, mlingo wa pod ukhoza kuwonjezeka, zomwe zimathandiza kuti pakhale zokolola zoyamba komanso kuwonjezeka kwachuma.

Kagwiritsidwe ndi Mlingo:Kumayambiriro kwa nthawi ya maluwa komanso koyambirira kwa nyemba zobiriwira, thirirani mbewu yonseyo ndi mankhwala a Triacontanol 0.5 mg/L, ndi kupopera malita 50 pa mu. Samalani kupopera mankhwala a Triacontanol pa nyemba zobiriwira, ndipo samalani kuti musasunthike kuti muchepetse kuchuluka kwake. Itha kusakanikirana ndi mankhwala ophera tizilombo komanso kufufuza zinthu popopera mbewu mankhwalawa, koma sungasakanizidwe ndi mankhwala amchere.

(2) Samalirani kutalika kwa mbewu ndi kuwongolera kukula kwamphamvu
Gibberellic Acid GA3:
Nyemba zobiriwira zikamera, thirirani ndi 10 ~ 20 mg/kg wa Gibberellic Acid GA3, kamodzi pa masiku asanu, kwa katatu konse, zomwe zingapangitse kuti tsinde litalikike, kuonjezera nthambi, kuphuka ndi kuphukira msanga, ndi pititsani nthawi yokolola ndi masiku 3-5.

Chlormequat Chloride (CCC), Paclobutrazol (Paclo)
Kupopera mbewu mankhwalawa kwa chlormequat ndi paclobutrazol pakati pa kukula kwa zokwawa zobiriwira kutha kuwongolera kutalika kwa mbewu, kuchepetsa kutseka ndi kuchepetsa kupezeka kwa matenda ndi tizirombo.
Kugwiritsa ntchito ndende: Chlormequat Chloride (CCC) ndi 20 mg/ youma gramu, Paclobutrazol (Paclo) ndi 150 mg//kg.

(3) Limbikitsani kubadwanso kwatsopano
Gibberellic Acid GA3:
Pofuna kulimbikitsa kumera kwa masamba atsopano kumapeto kwa nyengo ya kukula kwa nyemba zobiriwira, 20 mg/kg yankho la Gibberellic Acid GA3 likhoza kupopera mbewuzo, nthawi zambiri kamodzi pa masiku asanu, ndipo 2 zopopera ndizokwanira.

(4) Kuchepetsa kukhetsa
1-Naphthyl Acetic Acid (NAA):
Nyemba zikayamba kuphuka ndi kupanga makoko, kutentha kwambiri kapena kutsika kumawonjezera kukhetsedwa kwa maluwa ndi nyemba za nyemba zobiriwira. Nthawi yamaluwa ya nyemba zobiriwira, kupopera mbewu mankhwalawa 5 ~ 15 mg/kg 1-Naphthyl Acetic Acid (NAA) kumachepetsa kuthothoka kwa maluwa ndi makoko ndipo kungathandize kuti zikhwime msanga. Pamene kuchuluka kwa nyemba kumawonjezeka, feteleza ayenera kuwonjezeredwa kuti apeze zokolola zambiri.
