在种植园试验中,茶树每公顷施300公斤氮加200公斤 K_2O 作基肥(对照),加 P_2O_5年施120公斤/公顷或每次(六个处理)施120—960公斤/公顷,所有磷处理延长了枝条生长,增加了产量(特别是七月中旬到八月次生枝条),提高了叶片质量,年施磷120公斤/公顷或4—8年一次,每次分别施磷460—960公斤/公顷,获得了同样高的产量和质量,叶绿素含量在开始(五月)较低,直到十月逐渐增加,并且全部磷处理都比较高。
In the plantation experiment, the tea tree applied 300 kg of nitrogen and 200 kg of K 2 O as basal fertilizer (control) per hectare, 120 kg / ha of P 2 O 5 or 120-960 kg / ha each time (six treatments). All phosphorus treatments Prolong the growth of branches, increase the yield (especially from July to August secondary branches), improve the quality of the leaves, the annual phosphorus 120 kg / ha or 4-8 years once, respectively, 460-960 kg phosphorus / Hectare, achieving the same high yield and quality with chlorophyll content initially low (May) until gradually increasing in October and all phosphorus treatments being relatively high.
