Seed production and operation units must have laboratories and related equipment that can meet the inspection requirements. 3 or more germination boxes need more than 20,000 yuan, but the amount of germination test can not meet the needs of large-scale conventional seed production, build a standard germination room to reach the production scale needs more than 100,000 yuan cost, the general grass-roots unit is difficult to invest. In order to solve the contradiction between detection and supply and demand, the simple germination room for rice and wheat was constructed. After years of use, it shows that less investment, a large amount of sample input, and reliable test results. The relevant experience is summarized as follows for the discussion of my colleagues in the industry. The construction of the seed germination room provides favorable conditions for related production.
The submitted samples shall be processed according to the selected quality requirements (selected samples shall be exempted from treatment), then four 100 grains shall be randomly counted, and samples shall be taken according to the requirements of GB/I'3543.1-1995 Crop Seed Inspection Regulations. And numbered by sample. The Saomai brand hygiene roll paper from Henan Zhumadian Jinma Paper Mill was selected as the germination bed special paper, and the roll paper was stacked into 3 to 4 layers, neatly placed in a special plastic germination tray, and the paper bed was soaked with clean water. use.
Spread a good number of seeds evenly on the sprouting bed, with 2 replicates of X4 replicates per plate. Seeds of wheat, corn, soybeans, cotton, etc. are covered with 3 -4 -4 layers of paper. The rice trays are not covered and then germinated. Beds are full of water. Put the germinating plate neatly on the shelf of the germination box, put the rice dish in a stack and put an empty paper bed on it, and on the second day, pour water twice a day. Wheat dish flat. Change the position one time a day while changing the direction, and check the temperature and humidity periodically to keep the moisture and temperature almost the same.
Seed germination room drying rice germination after soaking with 300C water for 24 hours, the temperature is controlled at about 230C during the day, 300C at night, and the test days are 6}-7d. The germination temperature of dried wheat seeds was 16}-200C, and the test days were 5}-6 days. The test time was over 30d0 for the end of the acquisition, during the storage process, before the fumigation, before and after the processing, and after the test. After 6 days of wheat (rice 7d), the seedlings were classified according to the structure of seedlings as normal and abnormal seedlings and dead seeds, and they did not reach or fell below the level of structural traits one by one, and were no longer recorded in the later period (seedling structure was in accordance with the national standard) .
