Method used

Before and after the rice growth season, by water-soluble method, distribute various organic fertilizers; if adjacent to relevant aquaculture farms or with pig farms, chicken farms and cattle farm manure are processed in combination, directly Apply organic fertilizer to every corner of the field. Direct agricultural tractors are used for transportation, and the cost is relatively low.

Each big field piece is divided into smaller units by the field ridge again, and each level of water will be controlled by the field ridge to form a certain drop, and the water body of a paddy field will enter the next piece, and the whole will overflow the previous piece of field. Only in this way can we ensure that all crops can evenly obtain the nutrients in the water body and achieve the effect of average fertilization.

Abstract

The invention relates to an organic ecological farming system for a rice field. The system is characterized in that a water inlet canal, a drainage canal, a water inlet channel and a drainage channel are crossed to form the cross-shaped drainage rice field, a pump station is arranged at the crossed position of the crossed canals and channels, the rice field is divided into multiple field pieces in the type of plain terraced fields, fish ditches are arranged on the peripheries of the field pieces, and a fish pit is arranged at one corner of each field piece. According to the organic ecological farming system, high harvesting benefits of both rice and fish are achieved, and meanwhile the water conservation fertilizer conservation, low carbon and high ecosystem service functions are achieved; organic ecological farming can be carried out by transforming a common rice field near a good water source appropriately, and the optimized technology for transforming low yield fields and bottom land is achieved.

[0059] Example 1

[0060] Divide a large paddy field with about 200 mu as a unit, and divide it into 15-20 mu units (such as figure 1 Shown). Construct a kind of intersection of intake and drainage, with deep drainage ditch and shallow intake ditch;

[0061] Leave 2-3 meters on the slope of each ridge to plant other varieties of plants to increase the genetic diversity of the system. Or plant flowers with flowers, plant broad beans, potatoes, zucchini, rape, etc. in the wheat season, and plant other varieties different from the main rice on these ridges and related slopes in the rice season. When planting japonica rice as the main source, plant hybrid rice on the edge of the ridge. , Glutinous rice, etc.; flowering plants such as soybeans, sesame, pumpkins are planted on the ridge, which can effectively provide a source of nectar for insects to absorb a large number of natural enemies.

[0062] The rice varieties are mainly Nanjing series with good taste, with Nanjing 5505 and 9108 for selection; wheat uses the scab-resistant Yangmai series. At the same time, a large number of species such as lobster, green prawn, rice field eel and loach are reared in the system; as well as a variety of four major home fish species.

[0063] Feeding aquatic products provides bait for aquaculture species, in which residual bait and manure of the cultured object are used as fertilizers from rice cultivation. The water circulation can be promoted by the water pump at the intersection of the channel to promote the repeated flow of nutrients in the water body in the rice field to promote the effective absorption of nutrients. It also promotes the maintenance of high oxygen content in the water body, which is conducive to the healthy growth of aquaculture;

[0064] For lobster farming, a 4-meter wide and 1-meter deep side ditch must be excavated in the rice field to ensure the best growing environment for aquatic species.
