N'oge akwukwo 3, iji mmiri 200 mg / l paclobutrasol fesa ahịhịa ahịhịa mmiri nwere ike ịchịkwa oke uto na ịbawanye mkpụrụ site na 26%.
3. Mụbaa mmepụta
Na ogbo nke seedling ma ọ bụ na-eto eto nke mgbọrọgwụ, azuokokoosisi na akwukwo nri, spraying 50 kilogram nke 200 ~ 300ppm paclobutrasol ngwọta kwa acre nwere ike kwalite ndim nke akwukwo nri epupụta, shortening nke internodes, ike osisi, mma mma, na ụba mkpụrụ. Dịka ọmụmaatụ, tupu ị na-ebu cucumbers, fesa ha na 400 mg / l paclobutrasol ngwọta iji mee ka mkpụrụ ya dịkwuo ihe dịka 20% ruo 25%.
N'ime akwukwo akwukwo 4 nke cucumbers n'oge mgbụsị akwụkwọ na greenhouses, fesa 100 mg/l paclobutrasol mmiri mmiri iji mee ka internodes dị mkpụmkpụ, gbakọọ ọdịdị nke osisi ahụ, ma mee ka mgbọrọgwụ ya sie ike. A na-eme ka nkwụsị nke powdery mildew na downy mildew dịkwuo mma, a na-eme ka nguzogide oyi na-adịwanye mma, na-abawanye ọnụego ntọala mkpụrụ osisi. , ọnụ ọgụgụ mmụba nke mkpụrụ osisi ruru ihe dịka 20%.
N'oge akwukwo nke 3-4 nke kabeeji Chinese, ịfesa osisi ahụ na 50-100 mg / l paclobutrasol ngwọta nwere ike ịkụda osisi ahụ ma mee ka mkpụrụ osisi ahụ dịkwuo ihe dịka 10% -20%.
Mgbe radish nwere ezigbo akwụkwọ 3 ruo 4, fesa ya na 45 mg / l paclobutrasol ngwọta iji kwalite nguzogide ma belata ihe omume ahụ; N'oge nhazi mgbọrọgwụ anụ ahụ, fesa ya na 100 mg / l paclobutrasol ngwọta iji gbochie uto osisi. Ọ na-egbochi bolting, na-eme ka osisi ahụ doo akwụkwọ ndụ akwụkwọ ndụ, na-eme ka akwụkwọ ya dị mkpụmkpụ ma kwụ ọtọ, na-eme ka photosynthesis dịkwuo mma, na-akwalite ibuga ngwaahịa photosynthetic na mgbọrọgwụ anụ ahụ, nke nwere ike ịbawanye mkpụrụ site na 10% ruo 20%, gbochie bran cores, ma melite ahịa ahịa. .
Ịfesa edamame na 100 ruo 200 mg / l paclobutrasol mmiri n'oge mbụ na-eto eto zuru oke nwere ike ịbawanye alaka dị irè, ọnụ ọgụgụ pod dị irè na ịdị arọ, ma mụbaa ihe dị ka 20%.
