【正文】 1P1K1處理 SPAD 值 也要略高于其它處理，葉綠度值最小的處理為 N1P1K0 處理。 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)量對其產(chǎn)量呈顯著正相關(guān)。由 此證明樟樹吳茱萸春梢的萌發(fā)受肥力的影響要大于受環(huán)境的影響。瑞昌吳茱萸樣地的春梢數(shù)量相對較少，依然是 N1P1K1處理最高， N1P1K0和 N1P0K1處理的春梢數(shù)相對較少。s pruning makes it very hard almost pletely removed the third and fourth lateral branch, the following year39。 為了更深入的研究個配方肥對吳茱萸地徑 生長 的促進(jìn)作用，根據(jù)隨機(jī)區(qū)組試驗設(shè)計對 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 方差分析表 Table 6: camphor tree diameter growth of Evodia analysis of variance table. 變異來源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 差 Error 12 總變異 Total variance 20 注： *代表相關(guān)關(guān)系在 水平上顯著 **代表相關(guān)關(guān)系在 水平上顯著 Note: * On behalf of correlation between the level at ** significant correlation between the representatives of a significant at level 由表 6可知， 樟樹吳茱萸樣地 不同施肥處理間 ，地徑生長 存在 極 顯著差異，而 三個區(qū)組間無顯著差異， 由此證明樟樹吳茱萸地徑的生長受肥力的影響要大于受環(huán)境的影響。 From Table 5 below: camphor all fertilization treatments demonstrated by the increase in diameter than the control (no fertilizer application area). 3 Repeat for two years and the biggest increase in the average diameter of up to , as N1P2K1 treatment, followed by N1P1K1 treatment, an increase of diameter . The control (no fertilizer application area) shown the smallest increase in diameter only reached . As shown in Figure 2, rational fertilization of Evodia growth was stimulated, which N1P2K1 diameter growth to deal with the best recipe on behalf of the fertilizer camphor tree plot Evodia Evodia diameter growth in the most effective, but not on behalf of his output is the highest. 圖 2 ： 不同配方施肥吳茱萸地徑增長情況0123N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 CK地徑增幅（cm）樟樹瑞昌 從圖 2 可以看出，各施肥處理的地徑增幅均不同程度的高于 CK 處理。 From Table 2 is understood that the upper forest camphor Evodia relatively loose soil, which may be due to Evodia root mainly concentrated in the upper soil caused by soil bulk density average of the various treatment , in line with the normal range of soil bulk density, all fertilization treatments N1P1K1 treatment in both upper and lower layers of soil show the lowest values were 0 ~ 20cm is , and 20 ~ 40cm is , and the various fertilization treatments were different levels of soil bulk density lower than control CK treatment. So, it could of balanced fertilization on forest soil has improved Evodia role, which will help growth and development of a balanced absorption of nutrients Evodia. (B) Analysis of Evodia forest soil chemical properties (1) Different Fertilizer Evodia forest soil ammonium N, available phosphorus and potassium content of the changes Nitrogen, phosphorus and potassium act as necessary for plant growth as a large number of elements in plants throughout the growth cycle, plays an important Evodia balanced fertilization in the cultivation of the research, soil ammonium nitrogen, available phosphorus, available potassium as Evodia forest soil chemical properties analysis of important indexes, in the experiments their content were analyzed for fertilizer before and after to statistics, statistical results in Table 3 Table 3: Different Fertilizer Evodia forest soil ammonium N, available phosphorus and potassium content of the changes 單位： (mg/L) 類別Categories N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 CK 總體Total 銨態(tài)氮Ammonium 速效磷Available phosphorus 速效鉀Potassium This table methodology: a testing ground for various regions, the same treatment before fertilization, after fertilization of soil nutrient content of the difference， Units： mg/ L。土壤容重的大小取決于土壤機(jī)械組成、結(jié)構(gòu)以及有機(jī)質(zhì)的含量和性狀等因素。由此可以得出樟樹吳茱萸樣地土壤符合正常土壤孔隙度范圍，沒有存在板結(jié)現(xiàn)象，且合理施肥對土壤 孔隙 的調(diào)節(jié)有明顯作用，另外由于吳茱萸根系主要分布在上層土壤，根際微生物活動旺盛，致使上層土壤比較疏松，通氣性較好， 孔隙度 比較大，利于吳茱萸的生長發(fā)育，下層 孔隙度 相對比較小利于吳茱萸林地蓄水、保水。 （ 2）土壤總孔隙度 土壤是多孔體，土粒之間、土壤團(tuán)聚體之間以及團(tuán)聚體內(nèi)部均有孔隙存在。 土壤水分是植物生長所必需的，并參與土壤中各種物質(zhì)的轉(zhuǎn) 化過程，對林木的正常生長具有十分重要的意義。 12.
