The invention provides a saline-alkali soil improvement method with ecological water circulation. A water circulation ecological breeding system is designed in a paddy field to achieve solodization bymeans of fishing, so as to ameliorate the problem of saline-alkali of the paddy field. Through the water circulation system of the paddy field, feces are gathered in a feces tank, distributed into each piece of paddy field by a water pump, and absorbed by rice, and improves soil, so that damage caused by saline-alkali soil is reduced; and by breeding fishes and crabs, by means of special biorgansand feces of the fishes and the crabs, the saline-alkali content can be reduced. By applying an ecological water circulation technology, not only can saline be washed and reduced, but also a saline-alkali soil suddenness environment can be improved, soil organic matter is increased, and both the quality and the yield of the rice are improved.
Description
technical field [0001] The present application belongs to the technical field, and in particular relates to a method for improving saline-alkali ecological water cycle. Background technique [0002] In some areas north of Yinchuan in Ningxia, the groundwater level is low, which is likely to cause saline-alkali accumulation and turn white fields. The heavy salinity in the soil restricts the cultivation of food. For example, the quality of rice grown in this type of soil is relatively low and the yield is low. In order to solve the problem of soil salinity imbalance, in the prior art, the paddy field is irrigated and salt-washed. Specifically, a large amount of water is used to pour water into the paddy field several times before emptying, thereby reducing the salinity in the paddy field. Although this method can reduce the pH in the paddy field, it consumes a lot of water resources. In addition, the salinity and alkalinity in the paddy field are adjusted by adopting the met...
