發(fā)枝條在 11 月底(葉幾乎脫落)時對樣地內(nèi)吳茱萸單株進(jìn)行大力修剪,由于修剪尺度大每年的冠幅增長不能全部代表單株的生長情況,筆者在本試驗中主要選取地徑及次年春梢情況這兩個指標(biāo)作為吳茱萸生長量數(shù)據(jù), 地 徑試驗 結(jié)果表 5. (1) Different Fertilization diameter growth under the Evodia According to the market needs of the major whichever Evodia seeds pharmaceuticals, base management personnel in order to make it more flowering branches at the end of November more than germination (leaf nearly detached), the pairs of plots within the plant Evodia to vigorously pruning, as the annual crown pruning largescale growth can not be fully representative of the growth of plant, the author selected in this experiment the main spring shoot diameter, and the following year, the situation of these two indicators as Evodia growth of traffic data, to track test results Table 5. 表 5: 樟樹吳茱萸樣地施肥前后地徑增幅表 Table 5: camphor Evodia plot diameter growth before and after fertilization in Table 單位: cm 處 理Categories 重復(fù)一 Repeat 1 重復(fù)二 Repeat 2 重復(fù)三 Repeat3 平 均Average 施肥前 施肥后 增幅Increase 施肥前 施肥后 增幅 施肥前 施肥后 增幅 N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 CK 由表 5所示: 樟樹 各施肥處理表現(xiàn)出的地徑增幅均高于對照(未施肥區(qū)域)。 樟樹吳茱萸林地各處理 土壤容重 測定結(jié)果 如 表 2。由此 可見 吳茱萸 根系 集中分布的土壤上層保水通氣能力明顯高于根系分布較少的土壤下層 ,同時在平衡施肥的條件下,吳茱萸林地土壤的孔隙度要大,土質(zhì)比較疏松。土壤孔隙狀況直接影響土壤的通氣透水及根系穿插,是土壤肥力的重要指標(biāo)之一。 13 Test Results: (A) Analysis of Evodia forest soil physical properties (1) soil moisture content Soil moisture content of soil, one of the important physical properties of soil nutrients is only dissolved in water, in order to absorb and use for the trees. Soil moisture content of the water small cycles (such as plant growth, solute transport, soil erosion, etc.) and hydrological cycle in the (eg, regional landscape pattern) has a significant impact. Soil moisture is necessary for plant growth and to participate in a variety of substances in the soil in the transformation process, the normal growth of trees is of great significance. 圖 1: 樟樹吳茱萸林地各處理土層土壤含水率 Figure 1: camphor Evodia woodland soil moisture content of soil of each treatment 由圖 1 可以看出,樟樹吳茱萸樣地各處理土壤含水率最大值為 %,表現(xiàn)在 N1P1K1處理土壤的 20~40cm, 同樣 N1P1K1處理的含水量在土壤 0~20cm也表現(xiàn)為最大,上下層土壤的含水量均高于對照 CK 處理 ,且 含水率隨土層加深而逐漸增大 。s traditional Chinese medicine. Yoshimitsu, joy warm and humid environment, planting 23 year result, per plant can produce 1 ~ 3kg, 4 ~ 5 years into the Sheng Guoqi, per plant can produce 5kg. Plant life of 10 to 20 years, is a good ecological and economic use either of the Chinese herbal medicine species. Evodia is rich in alkaloids, limonoids, volatile oils, fatty acids, substances with high medicinal value in the treatment of cardiovascular diseases, antitumor, antiinflammatory has a very significant effect. Evodia39。隨著我國中醫(yī)藥事業(yè)的發(fā)展和出口需求量的增加, 吳茱萸 成為近年來藥用偏緊的藥材,收購價格由 20 世紀(jì)的 8~ 15元 /kg,漲至現(xiàn)在的 30~40 元 /kg。 喜光、喜溫暖潮濕環(huán)境, 定植 23 年結(jié)果,每株可產(chǎn) 1~ 3kg, 4~ 5 年進(jìn)入盛果期,每株可產(chǎn) 5kg。 B 研究不同磷、鉀肥用量與吳茱萸產(chǎn)量、有效成分含量的關(guān)系。 C 明確江西省吳茱萸栽培中土壤肥力狀況和養(yǎng)分限制因子。植株壽命 10~ 20 年,是很好的生態(tài)與經(jīng)濟(jì)兼用的中藥材樹種。隨著我國加入世界貿(mào)易組織 后,政府采取了積極的財政政策,擴(kuò)大內(nèi)需,促進(jìn)出口,加大了對吳茱萸 的需求量,但野生吳茱萸資源較少,人工種植吳茱萸產(chǎn)量也較低(初果期鮮果 ,盛果期 150kg/畝),發(fā)展高產(chǎn)吳 茱萸技術(shù)將會帶來 十分可觀 的經(jīng)濟(jì)效益和社會效益。s development to drug development as the center, the first being that the Chinese medicine herbal prescription preparation of the preparations to the high quality and efficiency of drug development, and second, by the Chinese medicine products to health care products, health beverage development and the third is the use of Evodia extract the aromatic oil is used for the leaves can be development of seasonings, spices, widely used in national defense, aviation, chemical, food, medicine and other industries. With the development of Chinese medicine in China and export demand increased, Evodia bee tight in recent years, the medicinal herbs, the purchase price from the 20th century, 8 ~ 15 yuan / kg, rose to the current 30 to 40 yuan / kg. As China joins the World Trade Organization, the Government has adopted a proactive fiscal policy to expand domestic demand, export promotion, increased demand for Evodia, but the wild Evodia fewer resources and lower production of cultivated Evodia (early fruiting phase Fruit / mu, Sheng Guoqi 150kg / mu), the development of highyield Evodia technology will have a very considerable economic and social benefits. The purpose of this study was through the study of Evodia changes of forest soil nutrients and soil nutrient limiting factors, identify Evodia yield and soil nutrient content relevance, determine a reasonable amount of fertilizer and fertilization methods, and the amount of fertilizer, time, frequency, etc. at the same time, bined with fertilization effect and the Li6400 portable photosynthesis, in studying the photosynthetic rate and Evodia Evodia Lam balanced fertilization technology, based on the ratio of trying to find the best fertilizer for the integrated nutrient management Evodia Lin and guide oleifera fertilization and nutrient management, and Evodia forest sustainable development, with minimum capital investment to obtain the greatest economic benefit to help farmers escape poverty. 13 試驗結(jié)果 : (一)吳茱萸林地土壤物理性狀分析 ( 1)土壤含水率 土壤含水率是土壤重要物理性狀之一,土壤中的營養(yǎng)元素只有溶解在水中,才能為樹木所吸收和利用。這是由于地表水分蒸發(fā),加上吳茱萸根系在上層分布比較多,土質(zhì) 比較疏松,以及水分通過土壤空隙滲透作用而造成。 樟樹吳茱萸林地各處理 土壤孔隙度 測定結(jié)果 如 表 1。 Be seen from Table 1, camphor forest soil porosity Evodia a maximum of 58%, performance in the soil 0 ~ 20cm of N1P1K1 treatment, the overall average of %, the upper soil porosity is generally higher than the lower soil porosity, various fertilizer treated soil porosity CK were higher than the control treatment. It can be derived camphor Evodia soil sample in line with normal range of soil porosity, paction phenomenon does not exist, and reasonable regulation of fertilization on soil porosity plays a significant role, and since Evodia root mainly in th
