During the autumn sowing, in order to ensure the quality of self-retained wheat seeds, germination tests should be conducted in advance in production.
Specific method: 1 kg of seed sample is taken, and 400 seeds are randomly selected from it. Put a piece of red brick in the container that is ready for germination test, and then put water in the container. The water surface is less than 1 cm above the top surface of the brick. Place two layers of toilet paper on the bricks, and spread a few good seeds on the toilet paper. It is required that the tablets do not rely on grains and a layer of toilet paper should be placed on the seeds. Normally, the daily average temperature is above 3°C for nights at 25°C and 4 to 5 days for nights below 25°C. The seeds are taken out and germinated seeds and non-germinating seeds are counted. Germination rate of more than 85% is a normal seed, and every 5% reduction in the use of seeds requires an increase of 2 kg per mu. Seeds with a germination rate of less than 75% cannot be used for seed application.
