Mushonga upi unofanira kushandiswa kudzora kutumbuka kwemakarotsi?

Makarotsi anogona kudzorwa kubva pakutumbuka nekushandisa mhando yemalonylureavanodzora kukura(kunyanya 0.1% - 0.5%) kana zvinodzora kukura kwezvirimwa zvakaita segibberellin. Zvakakosha kusarudza mhando yakakodzera yemushonga, kunyanyoisa, uye kuziva nguva chaiyo yekushandisa uye nzira kwayo.

Makarotsi imhando yemuriwo yakajairika, ine zvinovaka muviri zvakawanda uye inofarirwa nevanhu. Zvisinei, panguva yekurima, makarotsi anogona kusangana ne bolting, izvo zvinokanganisa goho uye mhando. Kuti vadzore bolting mumakarotsi zvinobudirira, varimi vanowanzo sarudza kushandisa zvinodzora kukura kwezvirimwa.

I. Maleic Hydrazide Growth Regulators

Mishonga inodzora kukura kwemakarotsi inonzi Maleic hydrazide ndeimwe yemishonga inowanzoshandiswa kudzora kuumbwa kwemakarotsi. Inodzora huwandu hwemahormone mumuviri wemuti, inodzivirira kureba kwehunde, uye nokudaro inonotsa nguva yekuumbwa kwemakarotsi. Nzira chaiyo yekushandisa ndeiyi inotevera: Munguva yekukura kwemakarotsi, kupfapfaidza 0.1% kusvika 0.5% mishonga inodzora kukura kwemakarotsi inonzi Maleic hydrazide inogona kudzora zvinobudirira chiitiko chekuumbwa kwemakarotsi. Zvisinei, zvakakosha kungwarira pakushandisa uye kudzivirira kushandiswa zvakanyanya kudzivirira kukura kusingawanzoitiki kwemakarotsi.

II. Zvinodzora Kukura Kwezvirimwa zvakaita seGibberellins

Kunze kwezvinodzora kukura kwemhando yemalonylhydrazine, magibberellin nedzimwe nzira dzinodzora kukura kwezvirimwa dzinogona kushandiswawo kudzivirira kukora kwekaroti. Magibberellin anogona kukurudzira kukura kwezvirimwa zvekaroti uku achidzivirira kurebeswa kwemadzinde, nokudaro achidzivirira kuitika kwebolting. Paunenge uchiashandisa, zvakakosha kusarudza mhando yakakodzera yemushonga uye huwandu hwawo zvichienderana nemamiriro chaiwo, uye kuziva nguva chaiyo yekushandisa uye nzira. Kazhinji, kupfapfaidza panguva yekutanga kukura kwekaroti kana usati wakora kunoshanda zvakanyanya.

III. Kukosha Kwematanho Akakwana Ekutarisira

Kunyangwe kushandiswa kwezvinodzora kukura kwezvirimwa kuchigona kudzora kumera kwemakarotsi zvinobudirira, matanho ekutarisira akazara akakosha zvakaenzana. Varimi vanofanira kusarudza mhando dzinoramba kumera zvakanyanya pakudyara, uye kusimbisa kutarisira minda nekuchengetedza hunyoro hwevhu uye tembiricha yakakodzera. Pamusoro pezvo, kubvisa zvipembenene nezvirwere nenguva ndeimwe yematanho akakosha ekudzivirira kumera kwemakarotsi.

Mukupedzisa, kudzora bolting mumakarotsi, zvinodzora kukura kwemishonga zvakaita semalonylurea kana gibberellins zvinogona kushandiswa. Zvakakosha kutarisisa kusarudzwa kwemishonga, kuwanda kwayo, nguva yekushandisa, uye nzira dzekushandisa. Panguva imwe chete, kusimbisa matanho ekutarisira akazara inzira yakakosha yekudzivirira bolting mumakarotsi. Kuburikidza nekutarisira kwesainzi uye kushandisa mishonga zvine musoro, varimi vanogona kuwedzera goho uye mhando yemakarotsi zvinobudirira.
