Method for detecting the germination rate of wheat seeds
Before planting wheat, it is necessary to do a seed germination test to identify whether the seed can be used. Here are some ways to determine the germination rate of wheat seeds.
1. Instrument method: take 2 kinds of wheat seeds, each 100 capsules. The seeds are placed on the germination bed in groups, and the seeds are seen at a distance of 1 to 2 times the length of the grains, covered, but without impeding the circulation of air. Label the germination dish, indicate the number of the specimen, the name of the species, the date of the experiment start, and establish the germination test record. At the end, the germination bed was placed in an intelligent seed germination room and germination experiments were conducted according to the temperature and the number of days prescribed by the technique. Finally observe the experiment and make a record.
2. Determination of bricks: Take 2 grains of wheat, 100 grains each. Find two bricks with high moisture absorption and suck enough water. Choose a section of 30 square centimeters with loose soil and less ground pests. Loose soil is leveled and irrigated. First use the bricks to draw out the area in the flattened soil. Sprinkle two kinds of wheat seeds in two brick-size soils. Press the bricks again. Drench the bricks and then pour the bricks into the bricks every day. Secondary permeable, maintain humidity, after 3 days to open bricks, you can check out the germination rate of wheat.
3. Soil determination: Take 2 wheat varieties, 100 grains each. Choose loose, fertile, moderately moist soil, turn over 30 square centimeters and open two small ditches. The depth of the ditch is about 3 centimeters. Place 2 seeds of wheat into two small ditches and cover the soil. 7 days later The germination rate can be calculated by digging out the wheat seed.
4. Wet towel assay: Take 2 grains of wheat, 50 grains each. The wheat seeds were soaked in water for 24 hours, and then 2 parts of wheat seeds were placed on two wet towels. The towels were rolled up while being placed, and the towels were kept moist every day. After 7 days, the germinated wheat seeds were counted.
5. Tissue Test Method: Take two varieties of wheat, each 50 tablets. After moistening the toilet paper, the toilet paper is placed in the vessel and wheat seeds are placed on top, and a layer of toilet paper is placed on the toilet until the wheat seeds are finished. After keeping the toilet paper moist, the germination rate of the wheat seeds was calculated after 7 days.
6. Determination of thermos: Place 1/3 warm water in the thermos and adjust the water temperature to 30-35°C. Take 2 kinds of wheat seeds, each 50 tablets, soaked in cold water for a day and a half, and then put them into two small cloth bags respectively. Hang them in the hot air above the thermos flask with a wire rope. After checking the water temperature of the thermos bottle once a day, it was kept at 30-35° C. After 3 days, the wheat seeds were taken out and the germination rate was calculated.
7. Determination of fine sand: Take 2 kinds of wheat seeds, 50 tablets each. The wet sand was placed in two pots. Two grains of wheat were sowed in two pots of sand, respectively. The sowing depth was about 3 cm. After that, the fine sand was kept moist. After 7 days, the seeds were plucked and the germination rate was calculated.
Belt Automation Centralized Control Unattended
In the field of mine production, the efficiency, real-time and safety of production and management directly affect the production efficiency and cost control of enterprises. As the main force of mine production, transportation system must also adapt to the requirements of this changing trend. That is to say, the construction, management and dispatching of the whole transportation system should be developed towards informationization, intellectualization, centralization and distributed control – it is imperative to establish a perfect dispatching command center of the transportation system. In view of this, a remote production command and dispatch system, which integrates control, protection and online browsing, emerges as the times require. At present, many modern mines have built such systems, and have achieved substantial direct and indirect benefits.
