摘要

【目的】揭示施肥对红松(Pinus koraiensis)穂条生长和生理的影响,为红松采穗圃的经营管理和穂条产量及品质的提升提供理论支持与实践指导。【方法】以红松采穗圃无性系为材料,采用单肥和混合肥多种施肥处理,分析氮(N)、磷(P)、钾(K)、氮磷(NP)和氮磷钾(NPK)不同水平下红松穂条生长(长度、粗度、芽长、芽粗、萌蘖数量)和生理(叶绿素含量、可溶性糖和可溶性蛋白含量)的变化情况,通过主成分与隶属函数相结合的方式综合评价并筛选出促进穂条生长和养分积累最优的施肥处理。【结果】施肥促进了红松穂条的生长并提高了穂条的叶绿素、可溶性糖和可溶性蛋白含量,其中P1(磷肥0.1 kg/株)处理促进可溶性蛋白积累的效果最好;P2(磷肥0.2 kg/株)处理对提高穂条的长度、粗度、叶绿素和可溶性糖含量的效果最好;P3(磷肥0.3 kg/株)处理促进主梢萌蘖效果最好,其次为P2处理。【结论】施肥促进了红松穂条的生长并提高了穂条的质量,0.2 kg/株磷肥对促进红松穂条的生长和提高穂条质量的效果最好。

Abstract

【Objective】This study examined the effects of fertilization on the growth and physiological traits of Korean pine(Pinus koraiensis)cuttings,in order to provide theoretical supports and practical guidances for managing P. koraiensis cutting orchards and enhancing cutting yield and quality.【Method】Using clonal plantlets from a P. koraiensis cutting orchard,various fertilization treatments(single and combined applications)were implemented. We analyzed the responses of cutting growth(length,diameter,bud length,bud diameter,and sprouting number)and physiological parameters(chlorophyll content,soluble sugar and soluble protein content)to different levels of nitrogen(N),phosphorus(P),potassium(K),nitrogen-phosphorus(NP),and nitrogen-phosphorus-potassium(NPK). The optimal fertilization treatment for promoting cutting growth and nutrient accumulation was comprehensively identified using principal component analysis combined with the membership function method.【Result】Fertilization significantly promoted the growth of P. koraiensis cuttings and increased their chlorophyll,soluble sugar,and soluble protein contents. Among the treatments,P1(0.1 kg of P fertilizer per plant)was most effective in promoting soluble protein accumulation. P2(0.2 kg of P fertilizer per plant)performed best in enhancing cutting length,diameter,chlorophyll content,and soluble sugar levels. P3(0.3 kg of P fertilizer per plant)achieved the highest sprouting number on the main shoot,followed by P2.【Conclusion】Fertilization effectively improved the growth and quality of P. koraiensis cuttings. The application of 0.2 kg of phosphorus fertilizer per plant yielded the most favorable results in promoting cutting growth and enhancing overall cutting quality.
