Description

A runoff collection device for rice and wheat double cropping farmland

Technical Field

The utility model relates to a runoff collection device especially relates to a runoff collection device that is used for rice and wheat double cropping farmland.

Background

Non-point source pollution is a great problem in intensive production of modern agriculture. With the advance of urbanization, arable land in China is gradually reduced. In order to ensure high yield of food in China, a large amount of fertilizer is applied to farmlands, the nutrient requirement of crops is far exceeded, the utilization rate of the fertilizer is greatly reduced, and the residual nitrogen, phosphorus and other elements are discharged into the environment. There are three main ways in which non-point source contamination occurs: run off, leakage and gas loss. For the farmland of rice and wheat double cropping, runoff is the most important way for causing non-point source pollution. Although the current methods for monitoring runoff are many, the method mainly focuses on monitoring runoff generated in dry land. For paddy rice and wheat paddy-upland rotation farmlands, runoff monitoring methods comprise two methods: (1) a runoff pond method. Although the method can accurately measure the water concentration and water quantity in the runoff generating process, the construction of the runoff pool is high in cost, and the runoff collecting workload is large; (2) and (3) a segmented flow collection method. The method mainly measures runoff by collecting runoff liquid for multiple times and then carrying out weighted average, and although the method is simple to operate, the method is not as accurate as a runoff pool method.

Patent publication is CN 201320330478.1's utility model patent discloses a runoff collection device that is used for rice and wheat double cropping farmland, in the different growth periods of rice, can adopt two outlet collection runoff of high difference, specifically do according to its demand to moisture: in the rice irrigation period, the drainage port at the lower part is closed, and the water enters the water collecting bucket from the drainage port at the upper part to collect runoff; when rice is put in a field or wheat is planted, the drainage port at the lower part is opened, and the rice enters the water collecting bucket from the drainage port at the lower part to collect runoff. The runoff is collected by opening and closing the water outlets with different heights at different periods, the water outlets are manually opened and closed, the labor cost is increased, and meanwhile, the water inlets and the water outlets are fixed in height, so that the runoff cannot be collected if the water level of a farmland is low; in addition, the water collecting barrel is directly connected with the guide pipe, when runoff in different periods is collected and multi-runoff needs to be collected, the water collecting barrel needs to be disassembled and assembled for many times to be replaced, and the process is complicated.
