Research on Agriculture Structure Adjustment and Economical Irrigation Quota on Water Shortage Area;

Comparison of three kinds of indices for calculating optimal irrigation quota;

Rational irrigation quota under limited water supply;

Spatial variability of rice irrigation quota and comprehensive irrigation quota in Yunnan Province;

Water saving irrigation norm model and its solutions;

An experiment was carried out in a solar energy greenhouse to study the effects of irrigation norms and water stress at different growth stages on the yield of tomato.

In order to reduce irrigation water use and improve irrigation efficiency for field crops,a irrigation device was designed.
