Asayansi amayamba kuganizira za kukula kwa mbewu, chifukwa masiku ano makampani amagwira ntchito limodzi ndi agrephere. Mwinamwake, lingaliro losavuta lolima "lomwe likukula nkhaka ndi teknoloji ya Dutch" lidzagwirizana ndi mlingo wa akavalo wa feteleza ndi zowonjezera zonse zoipa. Osati pachabe chifukwa m'nyengo yozizira mukhoza kupeza zokolola zambiri. Mwamwayi, luso lamakono lokula nkhaka mu wowonjezera kutentha m'nyengo yozizira limagwirizana kwambiri ndi dongosolo pogwiritsira ntchito feteleza, koma osati ndi kuchuluka kwake.
Kodi ndi zinthu ziti zomwe zimakulitsa nkhaka m'nyengo yozizira?
Choyamba, kuti zinthu zonse zichitike bwino, timasankha nkhaka kuti zikhale m'nyengo yozizira, mthunzi wolekerera, makamaka wokhala ndi mitundu yosiyanasiyana. Koma iyi ndi theka la nkhaniyo, mfundo yonse ili muzitsulo ndi motsatizana kwa supplementation.
Zipangizo zamakono za ku Dutch zomwe zimakula m'makonzedwe otentha m'nyengo yozizira sizikutanthauza kuti feteleza zimakhala zovuta kwambiri, chifukwa izi zimapangitsa kuti nthaka ikhale yonyowa. Apa, mgwirizano ndi kusagwirizana, komanso chisankho choyenera cha nthaka, ndizofunika:
- Kuti mukule, mukusowa nthaka yotayika kwambiri, komanso ngalande yokonzedwa bwino. Nkofunika kuti dothi lidzala ndi zakudya zambiri. M'nyengo yophukira, pamapeto pake, pafupifupi theka la tani la manyowa amabweretsedwa kumalo. Kuchuluka kwakukulu kumayambitsa salinization ya nthaka, kugwiritsa ntchito m'chaka kungathe kuwotcha mizu ya zomera.
- Chofunika kwambiri mu teknoloji ya Dutch yakukula nkhaka mu wowonjezera kutentha m'nyengo yozizira ndi kusankha malo. Silikulimbikitsidwa pambuyo pa zokolola kuti aike mabedi pamalo omwewo komanso nyengo yotsatira. Pambuyo pa zaka zinayi amaloledwa kuti azigwiritsenso ntchito. Apo ayi, mudzakumana ndi vuto la kuvunda wakuda kwa mizu ya zomera.
- Kulima nkhaka molingana ndi teknoloji ya Dutch kumaphatikizapo kuyambitsidwa kwa zakudya zonse ndi njira yochepa. Pa nthawi yonse ya zomera zimayenera kudyetsa kubzala ndi nayitrogeni. M'nthaka yokha ife timapanga 800 gr, ndiye 500 gr ndi njira yochepetsera ulimi. M'nthaka, timayambitsa zowonjezera m'chaka, ena onse atatha kukolola mbewu yoyamba milungu iwiri iliyonse.
- Malingana ndi sayansi ya kukula nkhaka mu wowonjezera kutentha m'nyengo yozizira, musanabzala, 2.5 makilogalamu a phosphorous ayenera kuwonjezedwa kunthaka.
- Potaziyamu imagwiritsidwa ntchito pa kilogalamu musanadzalemo ndiyeno mutatha fruiting. Nkofunika kuti feteleza alibe chlorine, yomwe imakhudza nkhaka.
- Musaiwale kupanga ndi magnesium mu kuchuluka kwa mapaundi. Izi sizingalole masambawo kutembenukira chikasu ndi kupweteka.
