Abstract
The utility model discloses a runoff collection device for wheat-rice double cropping farmlands. The runoff collection device is characterized by comprising a collection area and a water collection bucket; the collection area is provided with a water inlet and two water drain outlets; the two water drain outlets are formed up and down; the water inlet and the water drain outlets in the lower part are formed in the same horizontal plane, and are formed in a part which is 20 cm from a top opening of the collection area; the water drain outlets in the upper part are formed in a part which is 10 cm from the top opening of the collection area; different water drain outlets are selected according to different growth periods of wheat and rice and are connected with a water inlet of the water collection bucket through a water pipe; a bucket cover is arranged at an opening of the water collection bucket; exhaust holes are formed in the bucket cover so as to prevent errors due to rainfall or impurities effectively. The runoff collection device has the advantages that the construction cost is low, the in-situ monitoring can be realized, the operation is simple and convenient, and the result is relatively accurate.
Description
Technical field
The utility model belongs to agroecology, Research of Environmental Sciences field, is specifically related to a kind of runoff gathering-device for rice wheat two ripe farmlands.
Background technology
Pollution of area source is the significant problem that the intensive production of modern agriculture faces.Along with the propelling of Development of China's Urbanization, China arable land gradually reduces.In order to ensure China's grain high yield, a large amount of chemical fertilizer are applied to farmland, considerably beyond the demand of crop self to nutrient, cause utilization rate of fertilizer greatly to reduce, and remaining nitrogen phosphorus and some other element are all discharged in environment.The approach that pollution of area source occurs mainly contains three kinds: runoff, seepage and gas loss.For rice-wheat growing system farmland, runoff is that it causes the topmost approach of pollution of area source.
Although the monitoring method of runoff is a lot of at present, mainly concentrate on the monitoring of the runoff that nonirrigated farmland is produced.And for rice wheat rice field-upland field rotation farmland, the method for runoff monitoring has two kinds: (1) runoff pond method.Though the method can be measured water body concentration and the water yield of runoff generating process comparatively accurately, but runoff pond construction cost is large, and runoff collection work amount is large; (2) segmentation afflux method.The method mainly by repeatedly collect footpath flow liquid then weighted mean measure run-off, although simple to operate, be not so good as runoff pond method accurate.Therefore, be necessary to carry out for the ripe farmland of rice wheat two research of accurate, easy, economic runoff gathering-device.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of runoff gathering-device for rice wheat two ripe farmlands, and construction cost is low, can realize in-situ monitoring, and easy and simple to handle, and its result is more accurate.
The problem existing for solving above-mentioned prior art, the technical scheme that the utility model is taked is: a kind of runoff gathering-device for rice wheat two ripe farmlands, it is characterized in that: comprise collecting region and dust-collecting bucket, described collecting region is provided with a water inlet and two freeing port that are arranged above and below, freeing port below described being positioned at and water inlet, in same level, select different freeing port to be connected with the water inlet of dust-collecting bucket by water pipe according to rice wheat different growing stage; Be specially: top freeing port is to use the Rice irrigation phase, i.e. the Rice irrigation phase, top freeing port is connected with the water inlet of dust-collecting bucket; Below freeing port is that paddy rice is put the field phase and wheat growth stage is used, and paddy rice is put field phase or wheat growth stage, and below freeing port is connected with the water inlet of dust-collecting bucket.
Described collecting region is (3-4) with the top surface area ratio of dust-collecting bucket: 1.
The height of described collecting region is 40-60cm, water inlet is all positioned at from a mouthful 20cm place, top, collecting region with the freeing port that is positioned at below, when collecting region is buried underground, make water inlet, below freeing port flush with field face, described in be positioned at top freeing port be positioned at a mouthful 10cm place from collecting region top; Described dust-collecting bucket height is 50cm, and water inlet is positioned at apart from the cylinder 30cm place at the end, makes water inlet flush with field face when dust-collecting bucket is buried underground.
The water inlet of described collecting region is provided with valve with the freeing port that is positioned at below.
Described dust-collecting bucket bottom margin is provided with flanging, can effectively control the buoyancy of bucket; Open top is provided with bung, and described bung is provided with vent port, can effectively prevent the error that causes because of rainfall or foreign material etc., keeps bucket inner air pressure constant simultaneously.
Runoff gathering-device for rice wheat two ripe farmlands described in the utility model, with respect to prior art, has following advantage:
1) solved the problem that the same footpath flow device causing in the difference of different times footpath flow liquid water level height in the ripe farmland of wheat rice two is difficult to realize accurate and effective monitoring;
2) in the different growing stages of paddy rice, can be according to it demand to moisture, adopt two highly different freeing port to collect runoffs, be specially: in the Rice irrigation phase, the freeing port of below is closed, from top freeing port, enter dust-collecting bucket and collect runoff; When paddy rice is put field or while planting wheat, the freeing port of below is opened, from below freeing port, entered dust-collecting bucket and collect runoff;
3) the runoff gathering-device for rice wheat two ripe farmlands described in the utility model, except dust-collecting bucket, collection collecting region, footpath also can be used for collecting the runoff water yield of part, thus the large demand of runoff collecting amount while meeting torrential rain generation.
