杉树种子的产量一般有丰年(大年)和歉年(小年)之别..产量悬殊。如1973年我县收购到的杉树种子达十万多斤,而1974年只收购到种子1万多斤,因此造成丰年种子有盈余而歉年不足的现象。我县1973年冬收购的种子,除调拨外,还积存2万多斤,为了保持其发芽率,将这批种子进行了贮藏试验,从1974年4月贮藏到1975年3月,发芽率仍有21～34%。现将试验情况简介如下:
The production of cedar seed is generally rich year (New Year) and the year of apologies (year) .. Production disparity. For example, in 1973, the county purchased cedar seeds up to 100,000 kilos, while in 1974, only 10,000 kilos of seeds were purchased, resulting in a surplus of abundant seeds in the year of harvest but an insufficient year of shortage. The seeds purchased in our county in the winter of 1973 were deposited with more than 20,000 kilos in addition to the allocated ones. In order to maintain their germination rate, the seeds of these seeds were stored for storage from April 1974 to March 1975, and the germination rate was still high 21 ~ 34%. Now the experimental situation is as follows:
