| Abstract: | The experimental plantation of Populus tomentosa in combination with a number of measures on the sandy soil:including mixing with loam from a layer(T 1)and from a equal(T 2),mixing with straw from a layer(J 1)and from a equal(J 2),laying plastic film in the cave of plant(M),ditching deepen cultivate(K)etc.This text hold analyze on different measure on the improve effect of the sandy soil compose of particle size and effects of Populus tomentosa's root system quantity and the condition of distribution.The results showed that:every measure of soil improve and cultivate after five years,the sand of soil significantly redued,the clay and powder marked increase,the improving effect of different measure in proper order is T 1>T 2>J 1>J 2,Populus tomentosa's root system total and assimilate root quantity marked increase,its amount of increase show is J 2>T 1>M>K>J 1>T 2. |
