We compare the minute structures of several different kinds of rice stem and analyze the relationship between its minute structure and mechanical property.

In order to evaluate the differences of rice-stem lodging resistance between controlled irrigation and regular irrigation,and seek irrigation treatment which was beneficial to rice stem lodging resistance,rice-stem was taken as the research object,and the performance of rice-stem lodging resistance was studied under different irrigation treatments.

Studies on harvest index and culm lysine content in the transgenic brittle culm rice inserted lysine-rich protein gene;

The present study was conducted to determine the effect of feeding diets with whole crop rice brittle culm-1(WCR) on growth performance,nutrient digestibility,carcass traits and meat quality of growing-finishing pigs.

Under constant temperature conditions in the range of 17 -31℃ ,the development rate of black rice stem fly Hydrellia sasakii increased with the temperature as logistic curve,while the survivals of larvae and pupae,fecundity of adults and population trend index increased with temperature as parabola.

There are seven generations of black rice stem fly Hydrellia sasakii Yuasa et Ishitani yearly in Jiangxi Province.
