Microphenoletes na urea ka fatịlaịza na fatịlaịza fatịlaịza

① bata fatịlaịza na-agwakọta

A na-agwakọta sodium nitronel na urea ka agwakọta dị ka fatịlaịza, nke ahụ bụ, tupu ịgha mkpụrụ ma ọ bụ akuku. Microum na-agwakọta: 1.8% sodium nitrophonate (20-30 grams), kilogram 45 nke urea. Maka ngwakọta a, otu acre ezuru. Na mgbakwunye, enwere ike idozi ego urea n'ụzọ dabara adaba, ọkachasị dịka ọnọdụ ala.

② toppressing agwakọta

Banyere nkwado dị elu nke Topio, enwerekwa ụzọ abụọ dị iche iche: ala topdresssing na foliar topdreding.

Nke mbu, usoro ala toppdress, agwakọta dị ka 1.8% sodium nitropholetes (5-10 ml / g) na kilogram 35 nke urea. Usoro a dị oke ọnụ dịkwa banyere 1Cre. Ala toppdresssing na-eji akara a na-agwakọta, a na-atụ aro ka iji usoro ngwa e ji eri, nke ga-enwe mmetụta dị mma.

Nke abụọ, foliar fatịlaịza TopDoctoryting, a na-agwakọta na: 1.8% sodium nitropherole (3 ml / grams nke urea, na kilogram 60 nke urea, na kilogram 60.

However, spraying is sensitive to the growth period of crops, and it must be used in the best growth period for better results. Iji maa atụ: N'ime mkpụrụ osisi, okooko na fruiting ogbo, na ogbo, spring ogbo, n'oge ọ bụla na oge ọ bụla ga-enwe mmetụta dị mma n'ịkwalite uto.

Nchịkọta: Mmetụta nke ịgwakọta sodium nitronel na urea bụ 1 + karịa 1 + 1 dị elu karịa 2. UREA bụ fatịlaịza nitrogen, na sodium nitropes bụ ezigbo ihe ngwọta dị mma maka akụ uto. Ngwakọta agwakọta nke urea na sodium nitrophes nwere ike ịbawanye ngwa ahịa photolọ Akwụkwọ, na-eme ka ọnụ ọgụgụ dị ukwuu nke fatịlaịza nitrogen na-abawanye. A na-akpọ ya "ọla edo" ma ọ bụ "usoro ọla edo" nke fatịlaịza na ihe eji egbu.
