Portable in-situ determination device for crop seed shattering

Abstract

The invention discloses a portable in-situ determination device for crop seed shattering, which belongs to the technical field of agriculture, and aims to provide a shattering determination device which is simple in structure, convenient to operate and accurate in metering. The device comprises a seed receiving disc, the seed receiving disc is formed by hinging and folding two semicircular discs (6), and a first through hole (16) is formed in the center of the seed receiving disc; a cover plate is arranged above the seed receiving disc, the cover plate is formed by hinging and folding two semicircular plates (1), and a second through hole (14) is formed in the center of the cover plate; the seed receiving disc is fixedly connected with the cover plate through a transparent film (2), and the left end and the right end of the film are connected through a connecting piece (13); supporting legs (5) are hinged to the back face of the cover plate, auxiliary supporting legs (7) are hinged to the back face of the seed receiving disc, and a vibration device is installed in the seed receiving disc. The device is not influenced by environmental factors such as weather and manual operation factors, is high in measurement efficiency, and is a special device for in-situ measurement of seed shattering in a field.

Description

technical field [0001] The invention relates to a device for measuring the shattering property of plant seeds, in particular to a portable in-situ measuring device for the shattering property of crops, and belongs to the field of agricultural technology. Background technique [0002] The phenomenon that plant seeds are naturally scattered on the ground after they mature is an adaptive mechanism for self-reproduction of offspring formed by plants in the long-term competition for survival. For crops, if the shattering property of the crops is strong, although it is easy to threshing, the seed shattering in the mature stage will be aggravated under the action of external forces such as natural wind or human activities, resulting in crop harvest loss and affecting crop yield; on the contrary, if If the shattering property is weak, it will bring the defects of difficult threshing and large waste of seeds after harvesting. Therefore, accurate screening of crop varieties with mode...

Problems solved by technology

The above-mentioned traditional methods not only have many defects such as being greatly affected by human factors, poor accuracy and consistency, and troublesome operation, but also need to cut off the stalks of crop plants and bring them back to the laboratory for testing, resulting in low testing efficiency.

In order to overcome the deficiencies in laboratory testing, Chinese patent documents respectively disclose "a device for seed shattering of crops and their wild relatives (CN206540891U)", "an assembled rice shattering device (CN205301323U) ", "A device for measuring the shattering rate of old mans wheat (CN204989182U)". Although the above-mentioned patent can realize field detection, it still needs to intercept the stem of the plant, which will still damage the plant; it not only affects the growth of immature seeds, but also Mature seeds are easy to fall off during transportation, which ultimately affects the accuracy of the measurement data
