Objective:To investigate the variation of the population density of Bandicota indica .

Nowadays, the improved plank-tooth corn shellers based on the models in the developed countries were applied widely in the seed processing companies in China.

The susceptibility of Bandicota indica to Warfarin in Zhanjiang;

In this paper, we used the time series method to forecasting population fluctuation of Bandicota indica, the main pest rodent in rice fields of Pearl River Delta, Guangdong province.

Comparative experiments on threshing performance between short-rasp-bar tooth cylinder and spike tooth cylinder;

As the axial flow threshing and separating equipment were used more and more widespread and the theory of threshing was not researched deeply, the axial flow threshing and separating installation with helical blade plate were triturated according to the same kind of technique experience.
