本文调查了多量施肥对茶园土壤、茶树根系及制茶品质的影响。调查采用在茶园各部设置的土壤溶液采集器,采集土壤溶液进行分析。调查的数块茶园施肥量为每亩氮肥88.67——195.33公斤,磷肥34——76.67公斤,钾肥32——54.67公斤,这些肥料分10次施入,春肥(3月)、秋肥(9月)以施用有机肥为主,4——7月分施以硫酸铵为主的化学肥料。多量施肥以前,就连畦间也分布着较多的根系,多量施肥后,大部分茶园的畦间根系分布可能因腐烂或其它原因而减少。
This paper investigates the effect of large amounts of fertilizers on tea plantation soils, tea tree roots and tea quality. The survey was conducted using soil solution collectors set up in the tea plantations and collecting soil solutions for analysis. The quantity of fertilizers in several tea plantations surveyed was 88.67--195.33 kilograms per hectare of nitrogenous fertilizer, 34-76.67 kilograms of phosphate fertilizer and 32-54.67 kilograms of potash fertilizer. The fertilizers were applied 10 times in spring, spring (March), autumn fertilizer (9) Month) to the main application of organic fertilizer, 4 - July application of ammonium sulfate-based chemical fertilizers. Before fertilization, most of the tea plantations distributed more root systems. After much fertilizer application, the distribution of roots in most of the tea plantations may be reduced due to decay or other reasons.
