The overall production this year has seen a significant decline due to unusual climate. First, during the earthing up period, various production areas suffered from rainy weather, missing the best time for this practice. Secondly, there has been sparse rainfall in Shandong since Typhoon Lekima, and plots showed signs of drought. Although they were irrigated, irrigation is not as effective as natural rainfall. Finally, during the growing season of August and September, either frequent and unpredictable temperature changes or improper fertilization have limited the growth of autumn shoots and resulted in more blooms than in previous years.
In conclusion, a combination of factors has brought signs of reduced production in the northern ginger production areas in China, but as the planted acreages have been increasing, whether the total production has increased or reduced can not yet be decided.
