中文摘要
油橄欖(Olea europaea L.),也稱阿列布、齊墩果,屬木樨科(Oleaceae)木樨欖屬(Olea)的常綠闊葉喬木,因果實形似橄欖,果肉內富含油脂而被稱為-油橄欖,是著名的亞熱帶木本油料植物和果樹以及重要的經濟林樹木。甘肅白龍江河谷地帶的隴南市武都區是我國油橄欖最佳適生區,也是我國的油橄欖主產區之一。當前武都區的油橄欖生產普遍存在低產、不穩產甚至持續數年低產的問題,其主要原因除了氣候因素之外,粗放油橄欖園土壤管理模式直接導致的土壤肥力低下,以及樹體自身的營養失衡等因素都是油橄欖低產的重要原因。為此,針對隴南市武都區具備代表性的油橄欖園的土壤樣本進行取樣調查,并分析土壤養分狀況,了解該地方的油橄欖園土壤的養分現狀和肥力。以隴南市武都區表現較好的兩個栽培品種萊星和鄂植8號為試驗材料,通過配方施肥、單因素施肥試驗研究,初步了解油橄欖枝條與果實生長發育規律、不同物候期油橄欖葉片營養含量的動態變化、以及油橄欖的單株產量變化。經試驗數據分析總結出油橄欖園土壤養分標準,并初步提出油橄欖施肥時間、次數和肥料種類,為制定科學合理的油橄欖施肥策略提供必要的依據,提高科學施肥水平,指導油橄欖種植園的土壤合理性施肥及生產管理。
1、油橄欖自萌芽期起始生長,整年的生長進程呈現的節奏為“快-慢一快一慢”,新稍生長量的年周期具有很強的規律性。油橄欖在全年的生長周期內,共呈現三次生長高峰,即4月上中旬、6月中下旬之間和8月中下旬。在生長發育周期內,油橄欖果實從坐果開始經過6月下旬至7月上中旬和9月的中下旬兩次生長高峰期后共計生長150 d天后完全成熟。
2、針對結果枝N、P、K三種元素動態分析表明:油橄欖在兩個階段對N、P、K營養的需求量較高,分別是開花授粉、果實膨大期;油橄欖果實坐果期需要大量N、P元素,但是對K的需求量較少,幼果時期針對營養的需求狀況則與坐果期的需求相反,需要大量的K元素。
3、根據新梢生長量以及果實的年生長發育規律,且與結果枝的N、P、K三種元素的動態相結合分析得出,在隴南武都區應注重以下四個時期的施肥措施:一是在油橄欖果實收獲后,以含有N、P、K的復合肥為主;二是在打春后,3月至4月期間以施N肥和P肥為主;三是在5月末至6月的中旬期間,以N、P肥為主;四是在夏收時即6月至7月,以施K肥為主。
4、幼樹盆栽的試驗結果表明:N、P、K肥的施入對油橄欖的幼樹的枝條生長都有不同程度的促進作用:
N肥試驗以處理4最好,即每株施入100 g;P肥以處理3最好,即150 g/株,K肥的施入對生長有一定影響,但各水平之間無顯著差異,表明油橄欖幼樹生長對K肥施入量變化并不敏感。
5、盛果初期的油橄欖樹體大田單因素試驗結果表明:施入N、P、K肥能明顯促進枝條當年生長量,而N肥以處理3(株施125 g)最好。P肥以處理2(株施150 g)最高;K肥以處理3最好(株施200 g)。B肥和Zn肥也對新梢生長有一定促進,但是效果均不明顯。當樹體施入N、P、K、Zn、B肥后,均能提高花芽質量,其中以N、K和B肥效果最好,N肥處理2(株施50 g)、K肥處理3(株施150 g)和B肥處理3(株施150 g)肥效果明顯,有效花芽提高20%以上。在樹體施入N、P、K、Zn、B肥后,均能提高單株產量,N肥處理1(株施50 g)、P肥處理3(株施200 g)、B肥處理3(株施200 g)Zn肥處理3(株施125 g),均增產30%以上。
6、盛果初期樹體的配方施肥試驗表明:影響油橄欖樹體的生長量主次因子順序為:C>E>B>A>D,即K>Zn>P>N>B,選取施肥的最佳組合為A2B4C1D3E2,即各元素施入純量促進油橄欖新稍生長的最優組合為N:50 g;P:200 g;K:50 g;B:150 g;Zn:50 g.影響油橄欖有效花芽比例的主次因子依次為A>D>C>E>B,即N>B>K>Zn>P,選取施肥的最佳組合為A3D4C1E4B3,即各元素施入純量提高有效花芽比例最優組合為N:100 g;P:150 g;K:50 g;B:200 g;Zn:125 g.影響油橄欖單株產量的主次因子依次為B>A>C>E>D,即P>N >K>Zn >B,選出的的最優組合為A1B1C2D2E1,即各施入純量為:N25 g;P50 g;K100 g;B100 g;Zn25 g.

Abstract
Olive (Olea europaea L.) belongs to genus Olea of the family Oleace . Olive isan important economic forest tree, which both oil and fruit tree species. Its fruit arerich in oil, and its shape is like olives, so people named it as the olive. Wudu, inGansu province of China, is one of the main cultivation area of Chinese olive, whereit is the most suitable place for the growth of olive, this area is in the Bailong rivervalley area of Longnan, Gansu of China. But it has a problem that is lowerproductivity. Besides climate factors, extensive management mode of olive orchardthat leads to the low soil fertility, and tree nutrition imbalances are both importantreasons of low yield. Therefore, in order to understand the soil nutrient fertilitystatus of olive orchard, the soil of olive orchard was investigated which isrepresentative in Wudu, Then the soil nutrient status in that region. was analyzed Wecarried out the fertilization experiment. The cutivars were aelceted asLeccinoand EZ-8,and the experiment included fertilizer and single factor. In the process of test, olivebranches , fruit growth , development rules, the dynamic changes of the olive leafnutrient content of different phonological phase, and the yield were all determined.From the analysis of the experimental data, we can get the nutrient standards of olivegarden soil, and put forward the oil olives' dressing time, numbers and kinds offertilizers, which can provide an essential basis for making reasonable fertilizationstrategies for soil management and fertilization in olive orchards.
1. When olive grows from bud,full year growth rhythm of the process shows as“fast-slow-fast-slow”. It has three growth peaks which are from April 1st to15th,from June 16thto 30thand from August 14thto 20th. It's a total of 150 days for theolives to grow from results to full maturity, which has to go through two growthpeaks---from June 16thto July 15thand from September 15thto 30th.
2.Dynamic analysis aimed at branch N, P, K elements shows that: olive has ahigher demand for N, P and K element , which is in the two stages : pollination periodand fruit enlargement period; fruit-set period also needs a large amount of N and Pelements but less amount on K; Instead,Young fruit period for nutrition status need alot of K elements.
3. According to new shoots increment , the growth disciplinarian of fruits , andthe dynamic analysis of branch N, P, K elements , it shows that: In wudu,Longnanfertilization measures in the following four stages should be paid attention: First, after the harvesting of the olive, compound fertilizer containing N, P, K should be used.Second, N, P, fertilizer should be used from March to April. Third,from may 30th toJune 15th , N, P, fertilizer should begin to be used. Fourth, from June to July ,itShould choose fertilizer which contains K .
4. Experimental results for potted young trees show that: the use of N, P, and Kfertilizer aimed at the young olive branches has different promoting effect towardsbranch growth: processing 4 is the best, namely 100g per plant; to P fertilizer,processing 3 is the best, namely 100g per plant. The fertilization of K affects growth ,but there is no significant difference of each level. This indicates that young Olive isnot sensitive to the changes of K-fertilizer.
5. The results of the early Olive trees in single factor experiment show that:the fertilization of N, P, K can improve the growth of the branch in the current year,and processing 3 is the best (125g per plant)。 To P fertilizer, processing 2 is thebest(150 g per plant); To K fertilizer, processing 3 is the best(200 g per plant)。 Bfertilizer and Zn fertilizer will also promote the growth of fresh tip, but the results areboth not so significant. When the tree was applied to N, P, K Zn, B fertilization, all ofthem can improve the quality of flower buds, which fertilizer works best with the N,K, and B. To N fertilizer, processing 2 is the best(50 g per plant); to K fertilizer,processing 3 is the best(150g per plant); to B fertilizer, processing 3 is the best(150 gper plant)。 The fertilization has a significant result, and the flower buds effectivelyincreased by more than 20%. The fertilization of N, P, K, Zn, B can all increase theproduction of each plant. To N fertilizer, processing 1 is the best(50g per plant); to Pfertilizer, processing 3 is the best(200g per plant); to B fertilizer, processing 3 is thebest(200g per plant); to Zn fertilizer, processing 3 is the best(125 g per plant), and allof them increased by more than 30%.
6. The results of the early Olive trees in formula fertilization factor experimentshow that: the primary and secondary factors which affect the growth of Olive are:C>E>B>A>D, namely K>Zn>P>N>B, and the best combination of fertilizationchoice is A2B4C1D3E2, namely the best combination of each element to improve thegrowth of the fresh branch is N:50 g;P:200g;K:50g;B:150g;Zn:50g. Primaryand secondary factors which affect the effective flower bud ratio are: A>D>C>E>B,namely N>B>K>Zn>P, and the best combination of fertilization choice isA3D4C1E4B3, namely best combination of each element to increase the ratio of theeffective flower bud is N:100g;P:150g;K:50g;B:200g;Zn:125g. Primary and secondary factors which affect the production of each plant are B>A>C>E>D,namelyP>N >K>Zn >B and the best combination choice,is A1B1C2D2E1,namely each elementfertilization of N25 g;P50 g1K100 g;B100 g;Zn25 g.
