3: Kwalite bolting
Gibberellic acid GA3
Letus bụ naanị akwụkwọ nri na mgbọrọgwụ mgbọrọgwụ nke nwere ike ịkwalite bolting n'okpuru ọnọdụ ọkụ na ogologo ụbọchị n'ihi oke okpomọkụ na-ebute ọdịiche nke ifuru ifuru. Ịgwọ mkpụrụ osisi na ogologo ụbọchị na okpomọkụ dị ala nwere ike ịkwalite ọdịdị ifuru, mana nchekwa mkpụrụ chọrọ ihu igwe dị jụụ. Dịka ọmụmaatụ, na ule ụlọ ihu igwe artificial, n'ime 10-25 ℃, ma obere ụbọchị na ogologo ụbọchị nwere ike mechie na oge ntoju; n'okpuru 10-15 ℃ ma ọ bụ karịa 25 ℃, mkpụrụ osisi adịghị mma ma na-ebelata ihe nchekwa mkpụrụ; N'ụzọ megidere nke ahụ, nchekwa mkpụrụ bụ nke kachasị na 10-15 ℃. O siri ike idobe mkpụrụ letus, na ịgbasa Gibberellic Acid GA3 nwere ike ịkwalite bolting letus ma belata ire ere.

Gibberellic acid GA3
Mgbe letus letus nwere akwụkwọ 4-10, ịgbasa 5-10mg / L Gibberellic Acid GA3 ngwọta nwere ike ịkwalite bolting na okooko nke letus letus tupu kabeeji, na mkpụrụ osisi ahụ toro ụbọchị 15 gara aga, na-abawanye mkpụrụ.

4 Na-akwalite uto
Gibberellic acid GA3
Okpomọkụ kacha mma maka mkpụrụ osisi letus bụ 16-20 ℃, na okpomọkụ kachasị mma maka ịtọ ntọala bụ 18-22 ℃. Ọ bụrụ na okpomọkụ karịrị 25 ℃, letus ga-adị mfe too ogologo. Ìhè na greenhouses na shei ke ini etuep na mmiri nwere ike izute nkịtị uto nke letus. Ekwesịrị ịchịkwa mmiri n'oge nhazi oge na-aga n'ihu, ma ekwesịrị ịnye mmiri zuru oke n'oge oge isiokwu. Maka letus nke nwere mgbọrọgwụ dị nro, mgbe osisi ahụ nwere akwụkwọ 10-15, fesaa ya na 10-40mg / L nke gibberellin.

Mgbe ọgwụgwọ gasịrị, a na-eme ngwa ngwa dị iche iche nke akwụkwọ obi, ọnụ ọgụgụ nke akwụkwọ na-abawanye, a na-eme ka ọkpụkpụ dị nro na-agbatị ruo ogologo oge. Enwere ike iweta ya ụbọchị 10 tupu mgbe ahụ, na-abawanye mkpụrụ site na 12%-44.8%. A na-emeso letus letus na 10mg / L nke gibberellin 10-15 ụbọchị tupu owuwe ihe ubi, na osisi na-eto ngwa ngwa, nke nwere ike ịbawanye mkpụrụ site 10%-15%. Mgbe ị na-etinye gibberellins na letus, ekwesịrị itinye nlebara anya na ntinye uche iji zere ịgbasa oke ịta ahụhụ, nke ga-eduga n'osisi dị gịrịgịrị, belata ibu ọhụrụ, lignification na ọkwa ikpeazụ, ma belata ogo.

Ọ dịkwa mkpa iji zere ịgbasa mgbe mkpụrụ osisi ahụ dị ntakịrị, ma ọ bụghị na ị ga-adị ntakịrị, bolting ga-eme n'oge, uru akụ na ụba ga-efunahụ.

DA-6 (Diethyl aminoethyl hexanoate)
Ịfesa letus na 10mg / L DA-6 (Diethyl aminoethyl hexanoate) ngwọta nwekwara ike ime ka mkpụrụ osisi nwee usoro mgbọrọgwụ mepere emepe na nnukwu ị ga, na-abawanye mmepụta site na 25% -30%.

5. Nchekwa kemịkalụ
6-Benzylaminopurine (6-BA)
Dị ka ọtụtụ akwụkwọ nri, senescence letus bụ akwụkwọ nke nta nke nta na-acha odo odo mgbe owuwe ihe ubi, na-esochi ya nke nta nke nta nke anụ ahụ, na-akpụ akpụ na ire ere. Ịfesa ubi na 5-10mg/L 6-Benzylaminopurine (6-BA) tupu owuwe ihe ubi nwere ike ịgbatị oge na letus na-anọgide na-acha akwụkwọ ndụ akwụkwọ ndụ ọhụrụ mgbe nkwakọchara site na ụbọchị 3-5. Ọgwụgwọ na 6-BA mgbe owuwe ihe ubi nwekwara ike igbu oge senescence. Ịfesa letus na 2.5-10 mg /L 6-BA 1 ụbọchị mgbe owuwe ihe ubi nwere mmetụta kacha mma. Ọ bụrụ na a na-echekwa letus mbụ na 4 Celsius C maka ụbọchị 2-8, wee fesa ya na 5 mg / L 6-BA na akwụkwọ ma chekwaa ya na 21 Celsius C, mgbe ụbọchị 5 gachara ọgwụgwọ, naanị 12.1% nke njikwa ahụ. enwere ike ịre ahịa, ebe 70% nke ndị a na-agwọ nwere ike ịre ahịa.

Daminozide
Imikpu akwụkwọ na letus ị ga na 120 mg// Daminozide ngwọta nwere mmetụta nchekwa dị mma ma na-agbatị oge nchekwa.

Chlormequat chloride (CCC)
Imikpu epupụta na letus ị ga na 60 mg/L Chlormequat Chloride ngwọta (CCC) nwere mmetụta nchekwa dị mma ma na-agbatị oge nchekwa.
