【正文】 e upper soil and rhizosphere microbial activity vigorous, resulted in relatively loose upper soil, good aeration, porosity and relatively large, which will help Evodia the growth and development, the lower the porosity is relatively small benefit Evodia forest water storage and water retention. This shows that Evodia Root concentrated ventilation in the soil water retention capacity of the upper root distribution was significantly higher than the lower soil less, while under conditions of balanced fertilization, forest soil porosity Evodia larger, more porous soil. （ 3）土壤容重 土壤容重是衡量土壤供肥、保肥能力的重要物理指標(biāo)。 (3) Soil bulk density Soil bulk density is a measure of the soil for fertilizer, fertilizer ability to protect important physical indicator. 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照 CK 處理。三個(gè)重復(fù)內(nèi)兩年中平均地徑增幅最大的達(dá)到 ，為 N1P2K1 處理，其次是N1P1K1處理，地徑增幅為 。其次是 N1P1K1 處理 ，而 N1P1K0 處理的增幅相對較小。 From Table 6 we can see, camphor Evodia plots with different fertilization between diameter growth and there are significant differences in the three zones was no significant difference between the two groups, thus proving that the growth of camphor Evodia diameter greater than the impact of fertility affected by environmental impact. Fertilization can be drawn in different growth conditions in three different Evodia plots, diameter growth rate of no significant difference, but the same formula as the different fertilization on the growth of Evodia diameter had a significant difference in fertilizer on the ground diameter significant role in promoting the growth of this study to enhance Evodia Shushi, Shuhuashuguo, thinning pruning provide a reference at the same time in order to further locate the best Fertilization Evodia also provided the necessary reference. （ 2）不同施肥配方對吳茱萸次年春梢情況及產(chǎn)量的影響 (2) different fertilizer formula for the following year Evodia conditions and yield of spring shoot 前一年的修剪力度很大使得其第三第四側(cè)枝基本全部去除，次年的春梢基本發(fā)于第一，第二側(cè)枝上，筆者通過對樟樹基地中三個(gè)重復(fù)內(nèi)不同處理下的吳茱萸春梢情況來作為這一年當(dāng)中吳茱萸的一個(gè)生長指標(biāo)，也輻射出其開花及結(jié)果的數(shù)量。 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)。 說明施肥對吳茱萸春梢的萌發(fā)具有很好的促進(jìn)作用。 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，但總體來說各個(gè)施肥處理的單株產(chǎn)量都高于對照 CK 處理。 As can be seen from Figure 4 plots within the two spring shoot number and yield were in line with changes in the number of spring shoot a direct reflection of how much the level of the output of that year, the coefficient of determination from the diagram can be seen that the number of spring shoot was for their production a significant positive correlation. Evodia in May to do basically all the germination time of its survey of the number of spring shoot could serve as this year is expected to yield an important means of assessment. 圖5：春梢數(shù)量與產(chǎn)量間的相關(guān)關(guān)系y = R2 = 012345670 20 40 60 80 100 120 140 160春梢數(shù)（個(gè)）產(chǎn)量（斤） （ 5） 不同配方施肥對吳茱萸葉綠度的影響 (5) Different Fertilization on the impact of Evodia leaf greenness 圖 6 ： 不同配方施肥吳茱萸葉綠度調(diào)查情況0102030405060N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 CK葉綠度樟樹瑞昌 從圖 6 看出， 各施肥處理的 SPAD 值均高于 CK。 為了進(jìn)一步的研究不同配方施肥對吳茱萸的效應(yīng)，對 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。 瑞昌吳茱萸葉綠度整體較低，而 N
