前言茶叶的供求情况,由平衡时代向过剩时代推移。这种供给过剩情况,推想是由于上级茶与下级茶的价格愈来相差愈大。欲提高鲜叶品质,就得考虑增加施肥量,并进行深耕,施入有机物质,以改良土壤。从八月下旬到九月是深耕适期和改良土壤的时机。一般地说,深耕必致断根,在八月下旬至九月时期断根后其新根能旺盛地伸长。而在其他时期的断根,产生的新根却非 Preface Tea supply and demand situation, from the balance era to the era of excess. This supply surplus, the presumably because the price of higher tea and lower tea more and more difference. To improve the quality of fresh leaves, we must consider increasing the amount of fertilizer, and deep plowing, applying organic matter to improve the soil.
