Effect of water and fertilizer coupling on soybean yield in northeast semi-arid areas;

Effects of water and fertilizer coupling on root morphological characteristics and activities of rice;

Leaf photosynthesis of spring wheat under water and fertilizer coupling;

Effects of coupling of water and fertilizer under solution culture on morphological characteristics and activities of the root of rice Shanyou 63 were studied in 2004, and the phases of water force were considered.

The coupling of water and fertilizer test adopted the design of perpendicularity in jointing stage of the maize indicated that the water was a decisive factor of the maize growth under the conditions of different water and fertilizer.

Regulation of water-fertilizer coupling on root distribution and absorbing ability in Triticum aestivum-Zea mays intercrop system;

Effect of water-fertilizer coupling on yield of cantaloupes;

The effect of water-fertilizer coupling on the quantitativeindex of summer squash in greenhouse;

Effects of water and nitrogen coupling on growth and physiological characteristics of overground part of rice;

Under the condition of pot experiment, 4 moisture rates and 3 nitrogen application rates were designed at booting and anthesis stages to investigate the effects of water and nitrogen coupling on nutrients absorption characteristics in winter wheat with high quality and yield.

To realize agriculture sustainable development in semiarid region, we must protect reasonably and use fully the soil resource for this we must study the interaction between water and fertilizer.
