Before using the instrument, first understand the function of the instrument. Agricultural soft X-ray machines have been widely used in agriculture, especially in seed testing. The agricultural soft X-ray apparatus can measure the quality of seeds, full grain, empty grains and deformed grains, seed vigor, maturity, and internal pests of seeds. In addition to seeds, it can also be used in agriculture, forestry, plant protection, brewing and fishery and other scientific research and production departments, but also can be used for light metal, non-metallic materials inspection and detection, foreign trade inspection, archaeological and other departments.
Now is the time for seeding and preparing for seeds. Farmers' friends must pay more attention and check more when they purchase seeds. Checking the seeds is an important task before spring sowing. Because the quality of the seed has a great relationship with the seedling rate and seedling strength. In order to ensure the seedlings and seedlings of spring planting crops, it is necessary to select seeds that are full, orderly and strong. So, how do you check the spring seeds? For the seed scientific research and production department, the quality of the seeds can be measured with agricultural soft X-ray machines and sold to farmers.
You can also check the quality of the sowing seeds in the following three steps:
First, look at the purity of the seeds: first remove 200 seeds from the spring sow seeds, and then compare with the main traits of the pure seed, and finally count the purity of 100 seeds. The purity of seeds used in production should be controlled at more than 95%.
Second, to see the seeds of impurities: first remove a certain weight of the spring sowing seeds, and then pick out the impurities, and then call its weight, and finally calculate the percentage of seed cleanliness. The degree of purity of seeds used in production should generally be above 97%.
Third, to see the seed germination rate: first remove the spring sowing seeds 200, and divided into two, respectively, in the germinator, germination test at a suitable temperature, the use of ordinary germination method, can be used on several plates, plate filter paper or pad A layer of cotton, and add water to make it moist, and then put a certain number of seeds neatly and evenly placed on the top, put the plate near the stove or on the fire, so after about 7 days, you can see the number of seed germination Finally, the seed germination rate was calculated. Where the production of seeds, the germination rate should be above 95%.
