Abstract:

In order to solve the contradiction between high yield and economic income, high quality and water utilization rate of rice, the author proposed a new ecological planting and breeding method, that is chicken farming on the ridge and fish farming in the furrow under rice terrace cultivation. Contrast to from conventional rice cultivation mode, this method has ridges built in the paddies. The sides of the ridges are kept wet and the furrow has water at a certain level. The chicken and fish enjoys larger space for activities on the ridges and furrows and their activities could control the diseases, pests and weeds in the field. Pesticides are not used or used at small amounts. Faeces from the chicken and fish are returned to the paddies, cutting down the use of fertilizers, enriching the soil, and reducing non-point source pollution. Non-tillage is realized after the building of ridges, sludge is cleaned from the paddies before rice cultivation. The furrows could hold rain water and reduces irrigation. Therefore, this method has obvious economic, ecological and social benefits.
