Kuchita bwino ndi ntchito za Chlormequat chloride (CCC) zomwe zimagwiritsidwa ntchito polima mbewu

Chlormequat chloride (CCC) ndi mdani wa gibberellins.Ntchito yake yaikulu ndikuletsa biosynthesis ya gibberellins.Ikhoza kulepheretsa kukula kwa selo popanda kusokoneza magawano a maselo, kulepheretsa kukula kwa zimayambira ndi masamba popanda kusokoneza chitukuko cha ziwalo zogonana, potero kukwaniritsa kulamulira. kukulitsa, kukana malo okhala ndikuwonjezera zokolola.

Ndiye ntchito ndi ntchito za Chlormequat chloride (CCC) ndi ziti? Kodi Chlormequat chloride (CCC) ingagwiritsidwe ntchito bwanji bwino mu mbewu zosiyanasiyana? Kodi tiyenera kulabadira chiyani tikamagwiritsa ntchito Chlormequat chloride (CCC)?

Mphamvu ndi ntchito za Chlormequat chloride (CCC)
(1) Chlormequat chloride (CCC) imachepetsa kuwonongeka kwa "kutentha-kutentha" kwa mbewu.
Chlormequat chloride (CCC) amagwiritsidwa ntchito polima mpunga.
Kutentha kwa njere za mpunga kupitirira 40°C kwa maola opitirira 12, choyamba muzitsuka ndi madzi aukhondo, kenaka zilowerereni njerezo ndi 250mg/LChlormequat chloride (CCC) zamadzimadzi kwa maola 48. Madziwo ayenera kumiza mbewu. Mukatsuka njira yamankhwala, kumera pa 30 ℃ kumatha kuchepetsa kuwonongeka komwe kumachitika chifukwa cha "kudya kutentha".

(2) Chlormequat chloride (CCC) kulima mbande zolimba
Chlormequat chloride (CCC) amagwiritsidwa ntchito polima Chimanga.
Zilowerereni njere ndi mankhwala a 0.3%~0.5% kwa maola 6, yankho:mbeu = 1:0.8, youma ndi kufesa, thirirani njere ndi 2%~3% Chlormequat chloride (CCC) yankho la kulima mbeu, ndipo fesa kwa 12. maola. , koma mbande ndi zamphamvu, mizu imapangidwa, olimapo ndi ambiri, ndipo zokolola zimawonjezeka pafupifupi 12%.

Utsi 0.15% ~ 0.25% mankhwala mankhwala kumayambiriro siteji ya tillering, ndi kutsitsi voliyumu 50kg/667㎡ (ndende sayenera kukhala apamwamba, apo ayi mutu ndi kukhwima adzakhala kuchedwa), zimene zingachititse tirigu mbande zazifupi. ndi amphamvu, onjezani tillering, ndi kuwonjezera zokolola ndi 6.7% ~ 20.1%.

Sungunulani mbewu 80 mpaka 100 ndi madzi 50% ndikuviika kwa maola 6. Ndikoyenera kumiza mbewu ndi madzi. Yanikani pamthunzi ndiyeno bzalani. Izi zidzapangitsa kuti zomera zikhale zazifupi komanso zamphamvu, zokhala ndi mizu yokhazikika bwino, mfundo zochepa, zopanda mutu wa dazi, makutu akuluakulu ndi mbewu zonse, komanso kuwonjezeka kwakukulu kwa zokolola. Pakadali mbande, gwiritsani ntchito mankhwala a 0.2%~0.3% ndi kupopera 50kg Chlormequat chloride (CCC) pa masikweya mita 667 aliwonse. Itha kukhala ndi gawo pakugwetsa mbande, kukana mchere wa alkali ndi chilala, ndikuwonjezera zokolola pafupifupi 20%.

(3) Chlormequat chloride (CCC) imalepheretsa kukula kwa tsinde ndi masamba, imatsutsa malo ogona, ndikuwonjezera zokolola.
Chlormequat chloride (CCC) amagwiritsa ntchito kulima tirigu.
Kupopera mbewu mankhwalawa Chlormequat chloride (CCC) kumapeto kwa tillers ndikuyamba kuphatikizika kumatha kulepheretsa kufalikira kwa ma internodes apansi pa 1 mpaka 3 mfundo za tsinde, zomwe zimapindulitsa kwambiri poletsa kukhazikika kwa tirigu ndikuwonjezera kuchuluka kwa khutu. Ngati 1 000 ~ 2 000 mg/LChlormequat chloride (CCC) yapopera panthawi yolumikizana, imalepheretsa kufalikira kwa ma internode komanso kukhudza kukula kwa makutu, zomwe zimapangitsa kuchepetsa zokolola.
