摘要:
 为研究降水量对飞播造林成苗量和有苗样方频度作用的区域变化,在汉中降水量与飞播油松成苗效果研究的基础上,利用1997年安康飞播油松成苗期有苗样方频度和成苗量调查数据,采用相关分析法和逐步回归模型分析法,分析成苗效果与降水量的关系。结果表明,安康飞播成苗效果与年降水量呈显著负相关,而汉中呈极显著的正相关。两地成苗效果均与1月、6月和9-12月降水量呈负相关,与3-5月和8月降水量呈正相关,但相关度有差异。安康成苗效果与2月和7月降水量相关不显著,而汉中与2月降水量呈极显著的负相关,与7月呈极显著的正相关。充分说明飞播油松成苗效果不仅取决于当地年降水量,而且与当地降水量的分布密切相关。与汉中结果一致,在当地降水量范围内,RPA模型值均大于对照,证明RPA拌种能提高飞播后单位降水量的油松有苗样方频度和成苗量,且作用稳定。
Abstract:
 The relationship between precipitation and effective grown-up seedlings after afforestation by aerial seeding was very complex.In order to study the regional changes of the precipitation effect on the frequentness of sample plots with available seedlings and the quantity of available seedlings after aerial seeding,based on our previous study on the relationship between the precipitation and the effective grown-up seedling of Pinus tabulaeformis in Hanzhong,we used the data of the frequentness of sample plots with available seedlings and the quantity of available seedlings of P.tabulaeformis during seedling formation period in 1997 after aerial seeding in Ankang to conduct the correlation analysis and the stepwise regression model analysis to reveal the relationship between seedling effect and precipitation.A comparison was made between two regions.The results showed that in Ankang,after aerial seeding,the effective grown-up seedlings were negatively correlated with annual precipitation,but in Hanzhong,the correlation was positively significant.In two places,the relationships between the effective grown-up seedling and precipitation in January,June and September to December were negatively correlated,and precipitation in March to May,and August were positively related,but they had different degrees.In Ankang,effective grown-up seedlings associated with February and July precipitations were not significant,in Hanzhong the precipitation in February showed a very significant negative correlation,and in July a highly significant positive correlation.The results showed clearly that effective grown-up seedlings of P.tabulaeformis with aerial seeding not only depends on the local annual precipitation,but also closely related with the local precipitation distribution.Consistent with the results in Hanzhong,under the range of local rainfall,the RPA model value was larger than the control,indicating that seed dressing used RPA could improve of the frequentness of sample plots with available seedlings and the quantity of available seedlings of P.tabulaeformis in the unit precipitation,and its effect was stable.
