摘要/Abstract

摘要： 西北冷凉气候适合百合的生长,但其偏碱性的土壤是影响种球产量和质量的重要因素。本研究以东方百合“索邦”为试材,采用裂区设计试验,研究了冷凉气候下碱性土壤中施入不同量草炭和N、P、K、Ca肥对“索邦”百合种球产量、光合特性、光合色素含量、不同生长指标和不同器官干物质积累量的影响。结果显示,施用草炭对百合生物量、种球产量、个体种球鲜重没有显著影响,但会显著降低种球干鲜比;不同施肥处理下,单纯不施N、Ca肥的处理种球产量、鲜重和干重、光合效率、叶面积指数、生物量等指标高于施用了N、Ca肥的处理,单纯不施P、K肥处理下各指标总体较低。研究表明,百合品种索邦在试验地区(宁夏隆德县)生长状况良好,该地的气候条件较为适宜百合的生长;施用草炭对百合产量影响不显著,不能对碱性土壤起到有效地改良作用;碱性土壤下N、Ca肥的过量施用会影响微量元素的吸收,造成百合的生理性缺素,从而降低了百合产量和品质,因而碱性土壤下种植百合需要合理施肥,以保障百合的品质和产量。

Abstract: The area with cold and cool weather in northwest China is suitable for Lily’s growth, but the alkaline soil is an important factor to reduce’s lily yield and quality. The field experiments were conducted to examine the influences of peatmoss application and different fertilizer elements (N, P, K, Ca) on yield, photosynthetic characteristic, photosynthetic pigments content, growth index and dry matter accumulation of oriental Lilies “Sorbonne”. The results showed that the ball yield, dry weight of bulb had no significant difference under the peatmoss application treatments,but the dry/fresh ratio of bulb is reduced significantly. The production performance of “Sorbonne” including photosynthetic efficiency, leaf area index and dry matter accumulation under the fertilizertreatment without N or Ca was better than that used these, and without Por K these index were generally low. It was showed that “Sorbonne” growes well in the test area (Longde, Ningxia province) which climate condition is appropriate for lily planting. The application of peatmoss has not obvious function to improved lily yield and not have effectively improved action to alkaline soil; The excessive use of N or Ca fetilizer in alkaline soil will influence the absorption of trace elements and causing lily physiological deficiency, so the lily plangting in alkaline soil should be reasonable in order to ensure the quality and yield.
