Seed purity may seem negligible. In fact, seed quality inspection is the process of quality identification of seeds using sensory and instrumental methods. It is the key to ensure seed quality (seed quality). The contents of the grass seed test include the authenticity, purity, germination rate, clarity, number of seeds of other plants, viability, 1000-grain weight, seed moisture, seed variety identification, and seed health test. The conventional seed testing equipment can solve the problem of seed cleanliness (using the seed winnowing instrument and the blow-type cleanness meter for operation), moisture (seed moisture monitor) and germination rate (precise seed germination box is the best seed germination Environment, to avoid the influence of external factors on the germination rate of the seed) is more troublesome for purity.
Seed clarity This seed detection project may seem insignificant in the test of seed's clarity, but its impact in accuracy tests is still relatively large. Its impact is mainly reflected in the following four aspects: First, to increase the seeding rate of seeds. , Lowering the utilization rate of seeds; Second, affecting the growth and development of crops; Thirdly, sowing of impurities with high moisture content will affect the storage and transportation of seeds; Fourth, the low cleanliness of seeds will cause broken seedlings, which will affect the yield. The test for the degree of seed clarity can use a wind clarity meter that uses wind as the detection principle. So how to use the wind selection instrument?
After the instrument is purchased, the instrument is assembled first according to the diagram. Then turn on the power, put the sample to be measured into the cup, push it into the inside of the cup, press the switch, start to adjust the wind speed, and at the same time set the timing, during the time period, the wind will test the goods by The upward flow of air is fully levied, and it is advisable that impurities be trapped by the upper two layers and enter the debris cup. After the timer is over, the instrument will automatically shut down. If further experiments are required, it can be turned on again and the wind speed can be adjusted. After the test is over, the power supply is turned off and the impurities in the instrument can be cleaned.
The degree of importance attached to the detection of seed's degree of purity has gradually increased in recent years, and now almost all of the seed's clarity requirements have exceeded 95%.
