Kev ua tau zoo thiab cov txiaj ntsig zoo: ** Txhawb kev txhim kho hauv paus thiab txhawb cov nplooj photosynthetic efficiency. Thaum kawg, nws nce boll-setting tus nqi ntau dua 10% thiab nce lint tawm los thaum txhim kho fiber ntau.
Daim Ntawv Qhia Txog Kev Siv Paj Rwb
Thawj Daim Ntawv Thov: Thov thaum cov nroj tsuag muaj 3-5 nplooj tseeb; siv 0.5-1 gram ntawm 25% Mepiquat chloride aqueous tov ib evkawj.
Daim ntawv thib ob: Thov thaum cov nroj tsuag muaj 7-8 nplooj tseeb; Cov koob tshuaj tuaj yeem nce mus rau 1-1.5 grams ib mu.
Pre-topping Adjustment: Kho ntau npaum li cas raws li kev loj hlob txhua hnub. Rau cov teb uas pom kev loj hlob zoo (ntau tshaj 2 cm ib hnub), siv cov tshuaj tsuag lub teeb ntawm 1 gram ib mu. Rau cov teb uas tsis muaj zog, siv tsawg dua 1 gram kom tsis txhob muaj kev loj hlob ntau dhau uas tuaj yeem cuam tshuam kev sib txawv ntawm paj paj.
Daim Ntawv Thov Cov Txheej Txheem: Txau rau hnub so, hnub ci - ua ntej 10:00 AM lossis tom qab 4:00 teev tsaus ntuj. Rov ua dua yog tias cov dej nag tshwm sim hauv 6 teev tom qab txau. Tsis txhob sib tov nrog alkaline tshuaj tua kab lossis chiv.
