摘要

From 1993 until 1995, the influence of rodents on reforestation in the mountain regions near Beijing was studied in order to estimate the pressure of rodents on the seed supply, search for effective ways to decrease the loss of seeds due to consumption by rodents, and increase seed germinating power. It was shown that acorns, apricot pits and nuts are almost entirely carried away from the soil surface by rodents, thus suggesting that rodents have a great impact on the seed supply. When the seeds were sowed at a depth of about 5 cm, many of them were not eaten by rodents; 39% of acorns and 18% of apricot pits germinated on the following year. We propose that deep sowing of seeds may effectively decrease the loss of seeds through consumption by rodents.
