The study summary of silicon nutrition about rice soil in our country;

Research advance of silicon biochemical functions on crop;

The Research Status and Prospects about Plant Silicon Nutrition and Soil Silicon Fertility;

The two clusters of silicon isotopes of ores are consistent with silicon isotopes of Devonian thermal sedi.

For the first time uns program takes on the silicon isotope studies on petrogenesis and metallogenesis in the middle and lower reaches of Yangtze River,which have further expounded problems such as the formation and evolution of the magmatic rocks,the ore-forming material s origins and the relations of the two type copper deposits in the Yueshan copper orefield.

Concentration measurement of silicon and aluminum in reacting solution of combination flooding system is a key problem for studying chemical behavior of reservoir minerals in alkaline flooding system.

Effect of Polymer on the Measurement of Silicon and Aluminum;

Effect of silicon on effective nutritive element in soil was examined.

The morphology of silicon cells on leave surface in eight varieties of rice was observed by using scanning electron microscopy,and the content of silicon was detected by using energy dispersive X-ray spectrum.

It also was proved that the natural concentration in silicon decreases with aging and leads to tissue destructuration.
