沙培四个无性系 TR12023,TR162/9(壮株),TC9,和 DTI(生长缓慢的植株)的幼年茶树,施用氮肥来测定其方法和效果。当茶树生长期,就逐渐增加氮肥的吸收。氮肥直接影响到茶树的叶面积,在发芽前及休眠后,立即显著地吸收氮肥。其中 TRl 2023,TRl 62/9自始至终大量地吸取,占总量的75～78%,而 DTl,TC9仅达50～55。吸取的总氮和渗透淋失的氮约占总施氮量的95%,虽然壮株与非壮株之间吸氮效果是不同的,而吸氮后生成的干物质则相近。本文对生长强度不同的无性系幼年茶树在吸氮形式和施肥关系
Four young clones, TR12023, TR162 / 9 (strong), TC9, and DTI (slow growing plants) were used to determine their method and effect. As tea grows, it gradually increases the absorption of nitrogen fertilizer. Nitrogen fertilizers directly affect the leaf area of tea trees, and they significantly absorb nitrogen immediately before and after dormancy. Among them, TRl 2023 and TRl 62/9 were drained intensively from beginning to end, accounting for 75-78% of the total, while DT1 and TC9 only reached 50-55. Total nitrogen absorbed and leached nitrogen accounted for about 95% of the total nitrogen application, although the effect of nitrogen absorption was different between the strong and the non-strong ones, while the dry matter generated after nitrogen absorption was similar. In this paper, the relationship between nitrogen forms and fertilization of young tea clones of different clonal growth intensities was studied
