Prefabricated irrigation water intake and drainage control device for a paddy field

Abstract

A prefabricated irrigation water intake and drainage control device for a paddy field comprises an open slot base fixed on a ridge, a full-closing hand-operated gate and a semi-closing hand-operated gate, wherein the open slot base comprises a water intake gate groove, a right socket body, a left socket body and a bottom socket; the right socket body, the left socket body and the bottom socket together form the water intake gate groove of which the upper end is open; two socket grooves are formed in the open slot base; the full-closing hand-operated gate and the semi-closing hand-operated gate are respectively inserted in the two socket grooves. After the prefabricated irrigation water intake and drainage control device for the paddy field is embedded in the ridge, the paddy field can be irrigated accurately, drainage is controlled, the ridge does not need to be excavated and filled repeatedly, and the water layer of the paddy field is maintained; the prefabricated irrigation water intake and drainage control device for the paddy field is simple, convenient and feasible, can be popularized and applied, greatly reduces the labor intensity of farmers for water control, saves management and control time, completely prevents water leakage of the ridge, can effectively control the water layer of the paddy field according to the requirements on water intake and drainage in different growth periods of paddy rice, improves utilization ratio of agricultural water and avoids water resource waste.

Description

Technical field: [0001] The invention relates to the field of agricultural paddy field irrigation, in particular to the field of paddy field inflow and drainage control. Background technique: [0002] At present, the shortage of water resources in my country is becoming more and more prominent. All walks of life are implementing water-saving technologies. However, agricultural water is extensive and large. Due to the backwardness of my country's existing farmland irrigation facilities and extensive management of agricultural water use, it is reported that, At present, the utilization rate of agricultural water in my country is less than 50%, and the waste of agricultural water is very serious. [0003] In January 2012, the State Council issued the "Opinions on Implementing the Strict Water Resources Management System", in order to improve the utilization rate of agricultural water, improve the basic implementation of farmland irrigation, realize effective control of farmland ...

[0002] At present, the shortage of water resources in my country is becoming more and more prominent. All walks of life are implementing water-saving technologies. However, agricultural water is extensive and large. Due to the backwardness of my country's existing farmland irrigation facilities and extensive management of agricultural water use, it is reported that, At present, the utilization rate of agricultural water in my country is less than 50%, and the waste of agricultural water is very serious.

[0006] Farmers need to use shovels to continuously dig gaps and fill the fields with shovels every time water enters irrigation and drainage, which is not only labor-intensive, but also affects the water retention performance of the fields, and easily causes field ridge leakage, which directly affects the effective water use of rice fields. utilization rate

At the same time, this irrigation inflow and drainage control method excavates different depths of gaps on the field ridges, which is related to the subjective will of farmers, which not only affects the time of water inflow and drainage, it is difficult to control the water depth of paddy fields, and it is difficult to control the water depth of paddy fields. At that time, the accumulated water in the field could not be exhausted, which could not achieve the effect of preventing disorderly tillering of rice in the baked field, and could not meet the unified irrigation and drainage management requirements of paddy fields in each period; Farmers had in-depth exchanges and discussions, and participated in the practice of water control in rice fields, and designed a control plan that can meet the unified management of water inflow and drainage in rice fields
