To explore the different reagents in the spraying, the 'Zhongqiusucui Zao' peel the relative relationship between conductivity and cracking. In jujube white ripe, crisp ripe stage and ripe stage were sprayed on the concentration gradient of amino acid was 4 000 times, 6 000 times and 8 000 times liquid fertilizer, 10 mg/L, 30 mg/L, 60 mg/L Ca(NO3)2 solution, 0.01%, 0.05%, 0.1% H2O2 solution and 0.1%, 0.2%, 0.3% NaCl solution;Adopting DDB-303A conductivity meter for different periods in different parts of the processing of jujube fuit peel c...
