【正文】 tflower production of Alstroemeria , fertilizer with NK ratios ranging from 1: to 1: are remended (Bik and Van den Berg , 1981) . In Italy , greenhousegrowth Alstroemeria is fertilized with a NPK ratio of 2:: during vegetative growth 。 對六出花尤其那些用來作為切花的來說， 在使?fàn)I養(yǎng) 莖最少的同時(shí) 能維持花莖的高產(chǎn)是最為理想的，因?yàn)檫^多的營養(yǎng)莖將要從植株上被取出以增加植株內(nèi)部的光照強(qiáng)度。對于低比率的兩種肥料處理在植株的下部葉片上表現(xiàn)出了一些缺綠癥狀 。 含 P、 K 較低的肥料如奧綠 19612 產(chǎn)生的總的花莖數(shù)和花朵數(shù)與無肥處理大致相同而鮮重明顯偏重并且沒有缺綠現(xiàn)象。在 1996 年 5月 30日至 10 月 11 日之間，計(jì)算出產(chǎn)生的花莖數(shù)和單枝花序的花朵總數(shù)。從 1995 年 6月 9 日到 12月 12 日， 計(jì)算 產(chǎn)生的莖的數(shù)量和單枝花序的花朵數(shù)。在第一個(gè)實(shí)驗(yàn)中，我們比較了幾種具有不同配比的 NPK 和不同有效釋放期肥料對植株的影響；第二個(gè)實(shí)驗(yàn)，我們比較了兩種具有不同 NPK比和不同有效釋放期肥料的 3種不同濃度水平對植株的影響。 Madson (1995) 以盆栽六出花雜交系 FL101 為試材，在植株生長階段， 將 P濃度增至 74 mg﹒ L1 每次伴隨澆水施肥，花莖數(shù)和單枝花莖的 總花朵數(shù)將 增加而不需要更多的肥料。 Argo and Biernbaum (1993a) 稱消費(fèi)者希望六出花能在吊 籃 里經(jīng)歷整個(gè)夏季。外文翻譯中文 后期（非開花期）施用樹脂包膜緩釋肥對盆栽六出花后期生長 、 開花的影響 摘要： 將 7種不同的樹脂包膜緩釋肥（ RCF）（奧綠 19612， 18612， 141414， 131313， 19612和 Polyon 19612， 171717， ）施用于適于銷售的盆栽六出花雜交群 FL101 植株，以確定它們對植株后期生長開花的影響。 這種期望恰好可以由盆栽六出花來實(shí)現(xiàn)。同時(shí)她觀測到在植株開花后期基質(zhì) N、 P、 K 被 耗盡 ， 并 建議 在生長后期的開花季節(jié)施以樹脂包膜緩釋肥（ RCF）將有益與盆栽六出花 栽培。這次實(shí)驗(yàn)的目的是 為盆栽六出花生產(chǎn)者提供如何施用 RCF 芙蓉信息，同時(shí)也為肥料對六出花生長開花影響的更深入研究提供一個(gè)基礎(chǔ)。在實(shí)驗(yàn)的最后，將植株的整個(gè)地上部拿來稱重并數(shù)出營養(yǎng)莖的數(shù)目。在實(shí)驗(yàn)的最后，將植株的整個(gè)地上部拿來稱重并計(jì)算出營養(yǎng)莖的數(shù)量。因此，第二個(gè)實(shí)驗(yàn)我們對比了含有更低 P、 K的 HighN 2448 肥 。由于第二個(gè)實(shí)驗(yàn)的植株生長期較短同時(shí)在施用 RCF 時(shí)植株的個(gè)體一較小，因此植株的花朵數(shù)較第一個(gè)實(shí)驗(yàn)的少，花朵也較小。 第一個(gè)實(shí)驗(yàn)中，施用的 NPK 比為 9::5 的 RCF 比配比為 7:3:6 產(chǎn)生更多的花朵。 this ratio is changed to 2:: as the crop approches flowering (Cocozza Talia and Farina , 1991) .In th United State , Alstroemeria plants may be fertilized with as much as 600 mg﹒ L1 of N as KNO3 twice weekly (Healy and Wilkins , 1991) . Flower production increases and flower initiation is hastened when N is applied an 400 mg﹒ L1 every 7 to 10d (Smith et al. , 1998) . Potted Alstroemeria can be produced using the cutflower crop fertilizer remendations . Madson (1995) , working with potted Alstroemeria hybrid Fl101 , showed that increasing P fertilization up to 74 mg﹒ L1 , applied at every irrigation during the production phase, increased subsequent yield of flower stems and total number of florets per stem in plants that received no further fertilization . She also observed that the medium was depleted of N, P, and K at the end of the flowering period, and suggested that the use of resincoated fertilizers (RCF) during the postproduction flowering season might benefit potted Alstroemeria. Argo and Biembaum (1993b) investigated the use of RCF to improve the garden performance of flowering hanging baskets. Applying an RCF as a topdressing to Impatiens wallerina Hook f. in 25cm baskets prior to placing them in an outdoor environment allowed the plants to flower until the end of August, while the production of blooms decreased rapidly in nonfertilized plants. Adequate fertilization of flowering potted plants throughout their postproduction life requires high rates of RCF incorporated in the medium prior to planting, but high preplant incorporation rates of RCF are injurious to saltsensitive plants such as New Guinea impatiens (impatiens hawkeri Bull.) and tuberous begonias (Begonia tuberhubrida Voss) (Argo and Bienbaum, 1993b). Since Alstroemeria is sensitive to high salt levels (Bridgen, 1992。 in a subsequent experiment we pared the effect of there different concentrations of two fertilizers diffe
