施肥对红松嫁接樟子松生长和生理特性的影响
Effects of Fertilization on the Growth and Physiological Characteristics of Pinus koraiensis Grafted with Pinus sylvestris var.mongolica
摘要
Abstract
[Objective]It is to explore the effects of different ratios of nitrogen fertilizer,phosphorus fertilizer,and biological bacterial fertilizers on the growth and physiological characteristics of Pinus ko-raiensis grafted with Pinus sylvestris var.mongolica.[Method]16-year-old P.koraiensis grafted with P.sylvestris var.mongolica was selected as the experimental material,and nitrogen fertilizer,phosphorus fertilizer,and biological bacterial fertilizer were applied in combination,with no fertilization as the control group.The effect of fertilization on the growth and physiological characteristics of P.koraiensis grafted with P.sylvestris var.mongolica was explored.[Result]The combination of nitrogen fertilizer,phosphorus fertilizer,and biological bacterial fertilizer significantly increased the content of chlorophyll a,chlorophyll b,and total chlorophyll(P<0.05).Treatment 9(urea 300 g/plant,superphosphate 200 g/plant,and biological bacterial fertilizer 150 g/plant)showed the highest increase in tree height,which was 47.90%higher than that of the control group(P<0.01).The total chlorophyll content was 94.37%higher than that of the control group;The starch content was 29.03 times that of the control group(P<0.01).The soluble protein content increased by 1 113.83%compared with the control group(P<0.01).The content of malondialdehyde was the lowest(P<0.05);The peroxidase activity was the strongest,110.86%higher than that of the control group,with better stress resistance(P<0.05).[Con-clusion]Treatment 9 has the highest growth of tree height,chlorophyll a,total chlorophyll content,starch,soluble protein content,and peroxidase activity.The optimal fertilization of 16-year-old P.sylves-tris var mongolica is 300 g urea ∶ 200 g superphosphate ∶ 150 g biological bacterial fertilizer per plant.关键词
