Integrated cultivation technique of underground irrigation and film mulching for dryland wheat;

Multispot experiment and demonstration of watercollecting technique for dryland wheat by film mulching and hole seeding in furrows;

The relations between kernel quality and agronomic characters and the relations among agronomic characters of wheat and the relations among quality characters of kernel are analyzed using national area test of Huanghuai dryland wheat in 2000～2001.

Soil surface disposal of conservative farming of dry land wheat before sowing;

Using the high stability coefficient, stability parameter and adaptability parameter judged productivity and stability of 10 new dry land wheat varieties in Huanghuai dry land wheat regional trial in 2000～2001.

Study on the applied effects of "Green Drought Resistance agent" on winter wheat in dry land was conducted during 2002～2004 in Linfen,Shanxi.

The runoff of different rain harvesting surfaces as well as yield and water use efficiency under catchment irrigation wheat in dryland was discussed.

This paper studied the root growth and regulation effects of winter wheat in dryland areas with the method of a combination of field and pot experiments for 4 years.
