The relationship between soil bulk density with soil water, gas, heat flow and storage, as well as the adequacy of the supply of trees and coordination, while soil nutrients also have a multiplier effect. Soil bulk density depends on soil mechanical position, structure and anic matter content and the characters and so on. Camphor Evodia woodland soil bulk density determination results of each treatment, such as Table 2. 表 2 ： 各處理土壤各層容重變化情況 Table 2: layers of different treatments of soil bulk density changes in （單位 Units： ） Soil depth 處 理 Categories N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 CK 0cm20cm 20cm40cm 由表 2 知，樟樹吳茱萸林地上層土壤比較疏松，這可能是由于吳茱萸根系主要集中在上層土壤所致，各個(gè)處理土壤容重平均值為 ，符合正常土壤容重范圍，各個(gè)施肥處理中 N1P1K1 處理 土壤 上下層均表現(xiàn)最低，值分別為0~20cm 是 20~40cm 是 ，且各個(gè)施肥處理土壤容重均不同程度低于對(duì)照 CK 處理。其次是 N1P1K1 處理 ，而 N1P1K0 處理的增幅相對(duì)較小。 樟樹吳茱萸樣地春梢情況差別很大，其中 N1P1K1處理最高，為 128 個(gè)。 As can be seen from Table 7 areas were no significant differences between groups, but significant difference among treatments. Thus proving that the germination of camphor Evodia spring shoot by fertility affects more people than by the environment. Fertilization can be drawn in different growth conditions in three different Evodia plots, no significant difference in the number of spring shoot germination, but the same formula as the different fertilization on the number of Evodia of spring shoot germination had a significant difference in fertilizer on Evodia spring next year Kozue obvious role in promoting germination. （ 3）不同施肥處理對(duì)吳茱萸產(chǎn)量的影響 (3) Different Fertilizer Treatments on Yield of Evodia 圖4：不同施肥配方吳茱萸平均單株產(chǎn)量01234567N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 CK產(chǎn)量（斤）產(chǎn)量 由圖 4 可知，各施肥處理單株產(chǎn)量存在不同的差異，產(chǎn)量最高的處理是 N1P1K1，為 斤，產(chǎn)量相對(duì)較少的分別是 N1P1K0 和 N1P0K1處理，單株產(chǎn)量分別為 斤和 斤，其它施肥處理均不同程度的高于這兩個(gè)處理，但總體來(lái)說(shuō)各個(gè)施肥處理的單株產(chǎn)量都高于對(duì)照 CK 處理。 為了進(jìn)一步的研究不同配方施肥對(duì)吳茱萸的效應(yīng)，對(duì) 樟樹葉綠度 數(shù)據(jù)進(jìn)行了方差分析 ， 結(jié)果如表 8. From Figure 6 shows that the SPAD value of the various fertilization treatments were higher than CK. Camphor tree leaves leaf green Evodia plots the overall degree of change is not much, but can be seen in various processing data, N1P1K1 deal with SPAD value should be slightly higher than other treatments, the SPAD value of , SPAD value of the minimum for N1P1K0 processing, the SPAD value of . Evodia leaf greenness Ruichang overall low, but also slightly higher than the value of N1P1K1 handle other processing SPAD, leaf greenness value of the minimum treated as N1P1K0 processing. This shows that the different fertilizer formula for Evodia leaf chlorophyll content has a significant influence, directly determine the level of chlorophyll content of leaf photosynthesis strength, which further demonstrates the Evodia in balanced fertilization conditions, will significantly improve the nutrients required for plant growth and physiological indicators of , and SPAD chlorophyll meter can be a reasonable guide for the production of fertilizer to provide simple and rapid diagnostic method fo。 We can see from Figure 4, the existence of different fertilization treatments differences in yield per plant, yield the highest treatment is N1P1K1, was kg, yield a relatively small difference is that the N1P1K0 and N1P0K1 processing plant yields were kg and kg, other fertilizer treatments were different degrees of more than two treatment, but, overall, the various fertilization treatments CK yield per plant were higher than the control treatment. Description balanced fertilization is most conducive to raising the Evodia production, single application of P and K fertilizers is not conducive to raising the Evodia yield per plant. （ 4）春梢數(shù)量與產(chǎn)量間的相關(guān)關(guān)系 (4) The quantity and spring shoot the correlation between output 由圖 4中可以 看出二樣地內(nèi)春梢的數(shù)量與產(chǎn)量呈一致變化，春梢數(shù)量的多少直接反映了當(dāng)年的產(chǎn)量的高低，由圖中的決定系數(shù)可以看出春梢數(shù)量對(duì)其產(chǎn)量呈顯著正相關(guān)。瑞昌吳茱萸樣地的春梢數(shù)量相對(duì)較少，依然是 N1P1K1處理最高， N1P1K0和 N1P0K1處理的春梢數(shù)相對(duì)較少。 為了更深入的研究個(gè)配方肥對(duì)吳茱萸地徑 生長(zhǎng) 的促進(jìn)作用，根據(jù)隨機(jī)區(qū)組試驗(yàn)設(shè)計(jì)對(duì) 樟樹 吳茱萸樣地地徑數(shù)據(jù)做了方差分析結(jié)果如下表 6. As can be seen from Figure 2, the fertilization treatments in the increase in diameter in varying degrees higher than the CK treatment. And the two are dealt with N1P2K1 the biggest increase in diameter. Followed by N1P1K1 processing, and N1P1K0 handle the increase is relatively small. Thus, rational fertilization of Evodia growth was stimulated by single application of phosphorus and potassium fertilizer is not conducive to the growth of Evodia. For more indepth study of a formula fertilizer on the growth of Evodia diameter catalytic role, according to randomized block experimental design of the camphor tree diameter Evodia plot analysis of variance of data do the following Table 6. 表 6： 樟樹 吳茱萸地 徑增長(zhǎng) 方差分析表 Table 6: camphor tree diameter growth of Evodia analysis of variance table. 變異來(lái)源Variation Source 平方和Squares 自由度DOF 均 方 Mean Square F 值 F = Significant level 區(qū)組間 Area between the two groups 2 處理間 Treatments 6 ** 誤
