1979—1982年在查尔朱斯克林场对梭梭树和木叉明棵种子自然脱落动态进行了研究。先用硬厚纸片以一米的间隔将树冠分层,分别用不同的颜料涂染各层种子。每年在第一个秋寒(气温低到0℃)后的第5天开始每隔5天计算一次掉落的种子,持续一个月。最后计算圈定场地上种子的总量。按东→西,北→南的方向,测量种子从母树中心散落的最远距离,各次收集的种子按照国家标准,测定留在树上的种子发芽率,并限据高度和种子散落的远近测定脱落种子的发芽率。用具有0.04 m~2分度值的刻度板测量种子散落面积,用风速仪测定实验区风速。观察统计结果如下:
From 1979 to 1982, the dynamics of natural detachment of Haloxylon ammodendron and Cunninghamia lanceolata seeds were studied in the Chaljaskirchen field. First hard-coated paper at one meter intervals will be layered canopy, respectively, with a different paint coating layers of seeds. Every year, on the fifth day after the first autumn fall (temperatures as low as 0 ° C), the dropped seeds are counted every five days for one month. The final calculation of the total amount of seed on the field. According to the direction from east to west and from north to south, measure the furthest distance of seeds scattered from the center of the mother tree. The seeds collected in each time measure the germination rate of the seeds left in the tree according to the national standard and limit the height and the scattered distance Determine the germination rate of the exfoliated seeds. The scattered area of the seed was measured on a scale board with a division of 0.04 m ~ 2 and the anemometer was used to measure the wind speed in the experimental area. Observation statistics are as follows:
