Ubushinwa Bitanga Pgr Gukura Ibihingwa 4 Chlorophenoxyacetic Acide Sodium 4CPA 98% Tc

Igipimo cyo gusaba

P-chlorophenoxyacetic aside ni igenzura ryikura ryibimera bya fenoxyl hamwe nibikorwa bya auxin. Ikoreshwa cyane cyane mukurinda indabyo n'imbuto kugwa, kubuza ibinyamisogwe gushinga imizi, guteza imbere imbuto, gutera imbuto zitagira drupe, no guteza imbere gukura.

Uburyo bwo gukoresha

Gupima neza garama 1 ya sodium chloropenoxate, uyishyire muri beaker (cyangwa ikirahure gito), ongeramo amazi make ashyushye cyangwa inzoga 95%, ubyerekeze ubudahwema hamwe ninkoni yikirahure kugeza bishonge burundu, hanyuma wongeremo amazi kuri ml 500, ni ukuvuga guhinduka ml 2000 / kg yumuti urwanya kugwa. Iyo ikoreshejwe, nibyiza kuvanga umubare munini wibisubizo byamazi hamwe namazi kugirango bibe bikenewe kugirango utere, ushire, nibindi.
(1) Irinde kugwa indabyo n'imbuto:
① Mbere na nyuma ya saa cyenda za mugitondo, koga indabyo za zucchini zifunguye hamwe na 30/40 mg / kg y'imiti y'amazi.
Ut Shyira mg / kg 30 kugeza kuri 50 yumuti wamazi mukibindi gito, hanyuma ushire indabyo mugitondo cyumunsi wururabyo rwimbuto (shira indabyo mumiti yamazi, hanyuma ukore kumababi kuruhande rwikibindi kugirango ureke ibitonyanga birenze bitemba mubikombe).
③ Hamwe na mg / kg 1 kugeza kuri 5 yumuti wamazi, shyira indabyo inflorescence yibishyimbo, utere rimwe muminsi 10, utere kabiri.
④ Mugihe cyizuba cyigihe cyindabyo, hamwe na mg / kg 4 kugeza kuri 5 yumuti wamazi, gutera indabyo, gutera inshuro imwe muminsi 4 kugeza 5.
HenIyo 2/3 by'indabyo zifunguye kuri buri inflorescence y'inyanya, shyira indabyo hamwe na mg / kg 20 kugeza kuri 30 z'imiti y'amazi.

⑥ Mugihe cyo kumera kwinzabibu, shyira hamwe na mg / kg 25 kugeza 30.
HenIyo indabyo z'igitsina gore zifunguye, shyira indabyo hamwe na 25 ~ 40 mg / kg y'imiti y'amazi.
Days Iminsi 3 nyuma yuburabyo bwiza (bushyushye) bwimbuto, shyira indabyo hamwe na mg / kg 30 kugeza kuri 50 zumuti wamazi.
⑨ Mugihe cyindabyo za gourd yera yumugore, shyira indabyo hamwe na 60 ~ 80 mg / kg yumuti wamazi.

Ibintu bikeneye kwitabwaho

(1) Hagarika gukoresha imboga iminsi 3 mbere yo gusarura. Ni byiza gukoresha ibirenze 2, 4-ibitonyanga. Koresha akayunguruzo gato (nk'ubuvuzi bwo mu muhogo) kugira ngo utere indabyo kandi wirinde gutera amashami. Kugenzura cyane ibipimo, ubunini hamwe nigihe imiti igabanya kugirango ibiyobyabwenge byangirika.
(2) Irinde gukoresha imiti muminsi yubushyuhe, ubushyuhe nimvura kugirango wirinde kwangiza ibiyobyabwenge. Ntukoreshe iyi agent ku mboga zabitswe.

Imiterere y'ububiko

Imiterere yo kubika 0-6 ° C; Funga kandi ububiko bwumye. Guhumeka ububiko no gukama ubushyuhe buke; Kubika no gutwara bitandukanye n'ibikoresho fatizo byibiribwa.

Uburyo bwo kwitegura

Iraboneka hamwe na fenolike na aside ya chloroacetike na chlorine. 1. Guteranya fenol yashongeshejwe ivanze na 15% ya sodium hydroxide ya sodium, hamwe na acide ya chloroacetic aside yo mumazi itabangamiwe na karubone ya sodium. Byombi bivangwa mumasafuriya ya reaction hanyuma bigashyuha kugirango bigaruke kuri 4h. Nyuma yo kubyitwaramo, ongeramo aside hydrochloric kuri pH ya 2-3, koga kandi ukonje, korohereza, gushungura, gukaraba mumazi ya barafu, byumye, acide fenoxyacetike. 2. Nyuma ya chlorine irangiye, shyira ijoro ryose, bukeye bwaho mumazi akonje, kuyungurura, koza amazi kugeza ibicuruzwa bitagira aho bibogamiye, byumye.
