This paper is Introduced to make use of the powder of straw as filling to produce light weight plank of straw and magnesium cement about production craft,key technique and characteristics of product,a new way has been explored for the new use of the farm crop straw and the development of the building materials industry an environmental protection,economy and benefit.

Based on summing up the features and developments of nonwoven matrixes,the paper especially introduced and analyzed the actuality and prospects of the straw matrixes,and put forward the direction for the future.

To study the properties related to plant growing of different technical structure straw matrixes, we tested and analyzed the physico-chemical properties of straw matrixes.

10 Jinyou as the experimental material,the influence of differrent formula of wheat stalks substrate on growth vigor and leaf photosynthetic property was studied.

10 Jinyou as the experimental material, the effect of different level of fertilizer supply on the growth vigor, leaf pho-tosynthetic property and root morphology of cucumber seedlings in wheat stalks substrate were studied.

The objectives of this study were (1) to investigate the feasibility and methods of measuring quality of air-dried and ensiled stover quality of silage maize with near infrared reflectance spectroscopy (NIRS) with selected 165 from 900 air-dried samples and 150 from 675 ensiled samples of two years.
