Description

Special pool mouth device for comprehensive rice and fishing planting and cultivating paddy field

Technical Field

The utility model relates to the technical field of agriculture, in particular to a special pool opening device for comprehensive rice and fishing planting and cultivating of a paddy field.

Background

The comprehensive planting and breeding mode of rice and fishery integrates the food chain theory, ecological niche theory and interspecies mutualism symbiosis theory of agroecology, integrates traditional intensive tillage agriculture, modern low-consumption agriculture and three-dimensional high-efficiency agriculture into a whole, organically combines rice planting and aquaculture, constructs a rice and fishery co-operation rotation system by implementing engineering transformation on a rice field, comprehensively utilizes strategies such as scale development, industrial management, standard production, brand operation and the like, fully exerts the potential of water and soil resources, and realizes dual purposes of one water and one field, double harvest and planting and breeding win-win.

Successful development of comprehensive rice and fishery planting requires support of a whole set of key technologies, one of which is field water management. No matter rice cultivation or fishery cultivation, frequent water inflow and drainage are needed, so that a proper water layer condition and a proper water quality environment are provided, and efficient water inflow and drainage management is extremely important for a rice and fishery comprehensive planting and breeding system. The existing water inlet and outlet management measures for the rice and fish integrated planting field block mainly have two forms: the soil ridge digging opening separation net and the buried pool opening separation net are arranged. The ridge digging separation net is an old mode, namely a water inlet or a water outlet is dug in a ridge for water inlet and drainage, the water inlet and drainage are stopped by adopting a mode of taking soil on site for blocking or filling soil in woven bags for blocking, and a vertical rod gauze is adopted to enclose a water gap to prevent cultured fishes, shrimps and the like from escaping in a counter-current or forward-current manner; the method has the advantages that almost no additional cost investment is needed, the defect is obvious, the labor intensity of repeatedly excavating the blocking water gap is high, the water level management efficiency is low due to the fact that workers need to continuously visit the water level, the separation net is prone to falling down due to water flow washing, the separation net is difficult to clean after being blocked by floating objects, therefore, only a small number of fields can be managed by one worker, and accordingly, the low-efficiency management and the large cost are achieved. In order to improve efficiency and reduce cost, more and more producers control water feeding and discharging through burying pond openings, for example, an authorized bulletin number: CN205653762U, date of authorized announcement: 2016.10.19, respectively; authorization notice number: CN205421211U, date of authorized announcement: 2016.08.03, and adopting the above-mentioned net-separating measure, namely, the net-separating mode at the opening of the burying pool; this kind of mode is through the control rivers that open and shut of pool mouth flashboard, has greatly improved into drainage management efficiency, still need the manual work to continue to patrol and observe the water level, decides the processing of opening and shutting of flashboard, especially to the outlet, because used pool mouth is "water" design of walking down, the water route is open when pulling up the flashboard promptly, and the rivers circulate along the flashboard lower edge, if the manual work is patrolled untimely, then the field water can continue to flow out until the row is clean, this has very big risk to the comprehensive planting and breeding system of rice fishing. In order to overcome such a risk, i developed a paddy field outlet gate device with controllable water level, entitled bulletin number: CN211200324U, date of authorized announcement: 2020.08.07, innovate "water-running" mode, the rivers are discharged along the flashboard on the reason, and the water level is higher than the flashboard and predetermines the high drainage of beginning by oneself when the field, and the water level drops to and predetermines the high back and stop the drainage by oneself when the field to avoided "water-running" pond mouth device down to open the back field water-running and continuously flow out the managerial efficiency loss that the water level remained in the field that must someone lasted tour and decided the flashboard to open and shut. Through the matching use of the 'water feeding' tank mouth and the separation net, the field management efficiency of the rice and fishing comprehensive planting and breeding is greatly improved again. However, with the gradual popularization of crab culture in paddy fields, river crabs can easily cross the separation net or a gap between the separation net and the peripheral anti-escape membrane due to the strong climbing capability, so that the effect of the traditional separation net intercepting measures on the aspect of preventing escape through the pond mouth is greatly reduced, and serious economic loss is caused. In addition, the construction of the partition net for each pool opening also requires a large amount of work and investment.

In order to solve the problems that river crabs cannot be effectively prevented from escaping through a pool opening by the middle partition net in the crab culture in the rice field and the time and labor are wasted when the middle partition net is built for the pool opening in the rice and fish comprehensive culture paddy field, the utility model provides the special pool opening device for the rice and fish comprehensive culture paddy field to solve the problems and fill the blank of the pool opening special for the rice and fish comprehensive culture paddy field.
