The field experiment was conducted on the cultivated soil, sand and immature soil by using field wind tunnel.

Effect of fertilizer supplying method on yield formation and nitrogen (N) absorption were studied with the Japonica cultivar Zhendao 88 in immature soil in Huaibei.

An experiment was conducted in the seashore region of northern Jiangsu to probe the causality of fertility enhancement of the immature soil formed after land leveling with application of some organic manures such as pig manure,cake manure and straws.

Triggering response of winter wheat to nitrogen,phosphorus,and potassium nutrition in raw soil;

The PS-(F+C) slurry is prepared by mixing PS(Potassium Silicate in optimum modulus) as binding ingredient,fly ash(F) generated from thermal power plant and pulverized native raw soil(C) at the ancient city of Jiaohe as filling substance,and sodium fluosilicate as treatment agent,its initial setting time is obtained and the shrinkage behavior of its concretion is monitored.

The 3/4 length of the 110 kV transmission line along the Qinghai-Tibet Railway passes through the high altitude permafrost region,so the lightning activity and the soil geological condition of these regions will greatly affect the lightning protection function of the transmission line,and this should be considered in the design process.

Thermosiphon piles enable to increase the stability and bearing capacity of permafrost foundation and to prevent the foundation from frozen expansion and thaw settlement.
