摘要

以黄土高原天然次生林辽东栎(Quercus wutaishanica)种子为对象,采用双因素(覆土厚度和播种时间)完全随机试验的方法,研究土壤掩埋对辽东栎幼苗出土和生长的影响。结果表明:① 覆土厚度对辽东栎种子的出苗率有显著影响(P<0.05),出苗率随着覆土厚度的增加而增加,覆土厚度为10 cm时,出苗率达到最大值,分别为(53.2±20.7)%和(42.0±0.7)%;覆土厚度对幼苗的生长影响不显著。② 播种时间对0~3 cm覆土播种的出苗率影响显著(P<0.05),由于温度的差异,11月1日播种的种子出苗率高于12月10日,出苗率分别为(11.9±1.2)%~(53.2±20.7)%和(1.5±0.8)%~(42.0±0.7)%;播种时间对覆土播种的幼苗生长无显著影响,对地表播种的幼苗叶面积影响显著(P<0.05)。可见,土壤掩埋有利于辽东栎幼苗的出土,土壤掩埋对幼苗的生长影响不大。

Abstract

In this study, the effects of soil-covering thickness and sowing time on the emergence rate and seedling growth of Quercus wutaishanica, a kind of natural secondary forest on the Loess Plateau, were researched. The results were as follows: ① Soil-covering thickness affected significantly the emergence rate (P<0.05), the emergence rate was increased with the increase of soil-covering thickness and reached its maximum value when the soil-covering thickness was increased to 10 cm. The effect of soil-covering thickness on the seedling growth was not significant; ② The effect of sowing time on the emergence rate was significant when the soil-covering thickness was 0-3 cm (P<0.05). The emergence rate that the sowing time was on November 1 was higher than that on December 10 because of the temperature difference, and the emergence rates that the sowing time was on these two days were (11.9±1.2)%-(53.2±20.7)% and (1.5 %±0.8)%-(42.0±0.7)% respectively; the effect of sowing time on the seedling growth was not significant but the leaf area (P<0.05). Therefore, it could be concluded that soil-covering was advantageous for improving the emergence rate of Q. wutaishanica, but its effect on the seedling growth was not significant.

Key words： Quercus wutaishanica; seed; soil-covering thickness; emergence rate; seedling growth; the Loess Plateau
