摘要:

目的: 研究不同栽培方式对杨树生长和害虫抗性及其相互之间关系的影响,探索营造既生长良好又抗旱、抗虫的杨树栽培方式,为提高人工林的森林质量提供参考依据。方法: 2013年3月在河南孟州林场采用欧美杨108号(108杨)、N3016杨、丹红杨和南杨4种黑杨派无性系以纯无性系及4种无性系混合栽培的方式,通过抽样调查评估不同栽培方式对无性系长势、存活率及对杨树重要食叶害虫春尺蠖种群密度的影响;在2013年严重干旱部分无性系死亡的情况下,以抗旱较强的108杨作为补植树种于2014年3月对各小区进行补植,然后调查研究以108杨与其他品系混栽后各处理的生长状况及对春尺蠖的抗虫性。结果: 2013 —2016年间5种处理的年平均树高生长率和年平均胸径生长率都不存在显著差异;但补植108杨后,2016年丹红杨和南杨的树高、胸径都显著大于N3016杨。2013年108杨和N3016杨的当年存活率显著高于丹红杨和南杨(P < 0.05)。连续3年虫害调查发现样地中优势害虫为春尺蠖。3年间各处理的春尺蠖受害率和虫口密度由高到低依次为:108杨、N3016杨、4种无性系混栽、南杨、丹红杨。补植108杨后,108杨和N3016杨及各所在小区的受害率和虫口密度都显著降低;而丹红杨和南杨及各所在小区3年间的受害率和虫口密度都差异不显著(P < 0.05)。另外,2015年与补植108杨混栽的南杨和丹红杨小区的受害率显著低于4种无性系混栽小区,并且补植108杨在南杨和丹红杨小区的受害率和虫口密度显著低于在N3016杨和108杨小区。结论: 从生长、成活率和抗虫性等综合指标分析,108杨虽被害率较高,但具有成活率高、抗旱及耐害性强的优良性状;丹红杨和南杨具有较高的抗虫性并且生长性状良好,但抗旱性较差;3种黑杨无性系均可作为杨树人工林的适宜树种加以推广。并且,选择合适的无性系混栽能有效降低虫害发生,108杨与南杨或丹红杨进行混合栽培可以促进生长并提高抗虫效果。

Abstract:

Objective: This study aims to clarify the effects of different cultivation methods on the growth of four poplar Aigeiros Section clones as well as their resistance to drought stress and defoliator of Apocheima cinerarius (Lepidoptera:Geometridae) to explore a forest cultivation method that raises the poplar with fast growth,drought resistance and pest resistance,in order to provide a reference for improving the poplar plantation quality. Methods: In March 2013, four poplar Aigeiros section clones (Peuramericana cv. Guariento,P.×euramericana cl.N3016,P. deltoides cl. Nanyang and P. deltoides cl. Danhong) were planted in the forest farm of Mengzhou,Henan Province with different cultivation methods of pure or mixed forests. The effects of different cultivation methods on the growth rate,survival rate and population density of A. cinerarius,an important leaf eating insect of poplar,were evaluated through sampling survey. In the case that some clones died due to severe drought in 2013,Peuramericana cv. Guariento with strong drought resistance were used to replenish the planting in each plot in March 2014, and then the growth status of Peuramericana cv. Guariento forest and its mixture with other clones and their insect resistance were investigated. Results: There was no significant difference in the annual mean tree growth rate and annual mean DBH growth rate of the five treatments during 2013-2016. After the replantation with Peuramericana cv. Guariento,the height and DBH of P. deltoides cl. Danhong and P. deltoides cl. Nanyang were significantly greater than that of Peuramericana cl.N3016 in 2016. The annual survival rate of Peuramericana cv. Guariento and P.×euramericana cl.N3016 was significantly higher than that of P. deltoides cl. Danhong and P. deltoides cl. Nanyang in 2013 (P < 0.05). The main pest was A. cinerarius. In the three years,the damage rate of five forests and the population density of A. cinerarius from high to low respectively was:Peuramericana cv. Guariento,Peuramericana cl.N3016,mixed planting,P. deltoides cl. Nanyang and P. deltoides cl. Danhong. After replanting with Peuramericana cv. Guariento,the damage rate and the insect population density of Peuramericana cv. Guariento,Peuramericana cl.N3016 and their plots were significantly reduced. However,there was no significant difference in the damage rate and insect population density between P. deltoides cl. Nanyang,P. deltoides cl. Danhong and their plots during three years. In addition,the damage rates of the plots of P. deltoides cl. Nanyang and P. deltoides cl. Danhong mixed with Peuramericana cv. Guariento respectively were significantly lower than that of the plots of four clones mixed planting,and the damage rate and insect population density of the replanting of Peuramericana cv. Guariento in P. deltoides cl. Nanyang and P. deltoides cl. Danhong plots were significantly lower than that in Peuramericana cv. Guariento and Peuramericana cl.N3016 plots in 2015 (P < 0.05). Conclusion: The study reveals that P.×euramericana cv. Guariento,P. deltoides cl. Danhong and P. deltoides cl. Nanyang should be used as suitable species for poplar plantation. Although P.×euramericana cv. Guariento has high damage rate,but it has high survival rate and strong drought and pest tolerance. P. deltoides cl. Danhong and P. deltoides cl. Nanyang have high pest resistance and good growth traits. P.×euramericana cv. Guariento mixed with P. deltoides cl. Nanyang or P. deltoides cl. Danhong can promote growth and improve resistance to insect pest.
