Based on two factors, i.e., irrigation water and soil, the environmental quality of Yilan county＇s base of non-pollution agricultural products was evaluated by single pollution index. The main monitoring items included the content of Hg, Se, Cr, Pb, fluoride, and so on, and the evaluating results showed Pi〈1 which indicated that this area was fit for developing not only non-pollution products but also greenfood of A level.展开更多

There was feeding trough around the house. The water troughs were set in the middle of the fermentation bed and of the feeding trough on the short sides of the house, separating feed and water. There were electric aluminum alloy shutters in both long sides of the house for ventilation, cooling and heat preservation. On both short sides, there were fans and wet curtains. The spray cooling devices were in- stalled outside the roof for cooling. The environmental control in the piggery, includ- ing light, temperature, water, humidity, carbon dioxide and ammonia, was realized to run by computer automatically. The coconut chaff and chaff configuration were used as mattress material, realizing the advantages of fermentation bed, such as no smell, zero emission, high-quality meat, saving labor, controlling disease, no drug residue, producing fertilizer, intelligent control, mechanized operation, etc.展开更多
