Comparative Trial of 4 Cultivating Seedlings Methods for Ammopiptanthus mongolicus Maxim

Ammopiptanthus mongolicus\% Maxim, as a rare strong drought tolerant plant in desert and semi desert area,its natural distribution is becoming rare and narrow.The different cultivating methods will make much more differences on plantation of \%Ammopiptanthus mongolicus\% Maxim.
