【摘要】 １９９２－ １９９４ 年连续３ 年对腾格里沙漠东缘飞播区飞播植物生长状况调查结果表明：籽蒿在不同立地条件下生长状况差异很大，迎风坡生长最好，覆沙地次之，丘间地最差。在不同年份籽蒿生长状况主要受降水量的影响；三种固沙植物的生物量，沙拐枣最高为１９１．４ｇ 株－ １－ １，籽蒿次之为１８６．１ｇ 株－ １年－ １，花棒最少为５９．９ｇ株－ １－ １。更多还原

【Abstract】 Artemisia sphaerocephalla Hedysarum scoparium and Caligonum mongolcum are mian plants by aeroplant sowing at the easten rim of Tengli desert.The growth state of the plant by aeroplant sowing have been investigated from 1992 to 1994.the result showed that the growth state of Artemisia sphaerocfphalla is the best on the upwind slope of the dune,medium in the open-pit sand land;the worst in the lwo land between dunes,the growth state of Artemisia sphaerocephalla is mainly affected by the precipitation,the annual biomass of Caligonum mongolicum,Hedysarum scoparium and Artensisia sphaerocephalla are 191.4g 186.1g and 59.9g respectively.更多还原
