The carrier material could be degraded konjac flour by naturally.
So much drape materials accumulating in the soil turn to a kind of new “white pollution” which will not only spoil the quantity of the soil, but also pollute the environment.
Experimental Materials The materials considered include trifuctional polyether polyol(N330 with mw=6000 and N220 with mw=4000) provided by Chengdu chemical reagent company (China) and toluene diisocyanate (TDI) was used to manufacture flexible polyurethane foam.
All materials were used as received without further purification in order to mimic industrial application.

Compare with experimental method, to obtain the key parts of the structure by employed finite element simulation method is more efficient and practical In other words this method not only save labor and material resources, but also did not interrupt the regular production.

The information technology is used to extract growth character parameters of poplar, and the neural networks is used to establish the relational model of the character parameters and wood materials and wood production of poplar, these models are used to monitor and analyze growth situation and materials of poplar and potential utilization value, so can correctly assess the reasonable use of the poplar, meanwhile provide the basis for the oriented cultivation of poplar management, which have important theory value and practical significance.
This requires timely monitoring, forecasting and analyzing during the course of growth conditions, poplar material and standing potential value[1].
Using these models, we can analyze and assess the growth status of poplar materials and their potential processing and utilization of the value, and provide guidance for the managers, as well as provide the base for poplar management and oriented cultivation.
