Effects of application of different fertilizers on rice growth and nutrient absorption

The results of our experiments indicate that dry cultivation brings about remarkable effects on the rice growth and brings about the lowest yields.

According to the pollutant burden dixchargedinto Datong River from the factories, a simulation test in theeffect of Organic sewage irrigation on rice growth was conduct-ed.

The results show that the energy flow method gains an advanage over the simple investigation of community number dynamic in reflecting scientifically and accurately the harm level of Sogatella furcifera and the different control levels of Pirata subpiraticus to Sogatella furcifera at different rice growth stages.

To unveil the mechanism of effect of elevated CO_2 concentration and temperature increasing on growth,development and yield formation of rice,many physiological characteristics of rice were measured from the half-open CO_2-temprature gradient system,which treated whole growth duration of rice by different CO_2 concentrations and temperature levels.
