摘要: |
为减少油松定植后的死亡率,在控制成本的基础上促进油松良好生长,该研究采用裂区实验设计方法,选取三个灌溉水平与三个园林废弃物有机肥施用量进行比较试验,通过测定油松树高、胸径、叶绿素及叶片养分含量指标探究灌溉和施用有机肥对油松林木生长的影响。结果表明:灌溉可以显著提高油松在胸径、树高、生理等方面的生长指标,树高和胸径在中水灌溉(A2)下的促进效果甚至高于高水灌溉(A3); 试验处理1 a后,施肥对油松的生长影响显著,但三个施肥水平间的差异不显著; 灌溉与施用有机肥之间不存在显著交互作用。综上可知,施肥和灌溉对油松的生长会产生显著的促进作用,从施肥和灌溉的效果并综合资源利用效率的角度考虑,少量施用有机肥,并以80 L·(10天·株·次)-1的灌水量在生长季(4月—9月)进行滴灌是较为经济、有效的油松生态林管护措施 |

Abstract: |
In order to explore the effects of irrigation and application of organic fertilizer on the growth of Pinus tabulaeformis after planting on the basis of cost control. The split area experiment design method was adopted in this study. Three irrigation levels and three application amounts of organic fertilizer of garden waste were selected for comparative experiment. The effects of different treatments on the growth of P. tabulaeformis forest were studied by measuring the height, DBH, chlorophyll and leaf nutrient content indexes of P. tabulaeformis forest. The results were as follows: Irrigation can significantly improve the growth index of P. tabulaeformis in DBH, tree height, physiology and other aspects, and the promotion effect of tree height and DBH under medium amount irrigation(A2)is even higher than that under high amount irrigation(A3); After one year of experimental treatment, fertilization had a significant effect on the growth of P. tabulaeformis, but there was no significant differences among the three fertilization levels; There was no significant interaction between irrigation and organic fertilizer application. Fertilization and irrigation can significantly promote the growth of P. tabulaeformis. From the perspective of the effect of fertilization and comprehensive consideration of resource utilization efficiency, it is an economic and effective management and protection measure for P. tabulaeformis ecological forest to apply a small amount of organic fertilizer and drip irrigation in the growing season(April to September)with the amount of 80 L·(10 d· plant · time)-1. |
