1. Insufficient time for preventing seed soaking, affecting germination and uniformity When rice seeds absorb enough water, the volume expands, the cells change their original dormancy, and they start to elongate and differentiate. The length of soaking time depends on the temperature of the water. When the water temperature is 10°C, it takes 90 hours to suck enough water, soaking for 3 or 4 days; when the water temperature reaches 30°C, it takes 40 hours, soaking for 1 or 2 days. When water is soaked, there is not enough water, and the buds in the seed valleys are not uniform, but they cannot be soaked for too long. When germination is still necessary to maintain the state of rice paddy seeds (wet seed coat moist, the valley does not see clear water is appropriate). For example, if the seeds are short of water, the roots will have short shoots; if the water is too much, the roots of the shoots will be short and the root buds will not meet the requirements for strong shoots with the same length.
2. The most suitable temperature for germination before seedling dew prevention is 30°C～32°C, and the maximum temperature is 40°C. If the temperature is lower than the minimum temperature, germination will be slow and even stop. If it is too long, it will cause bad seeds; when it is higher than the maximum temperature, germination will be hindered and there will be a risk of “burning budsâ€. Therefore, the germination temperature must be strictly controlled. If the seeds are turned too much before the dew-whitening, the hot gas in the piles will be lost and the proper temperature requirement for germination will not be achieved, which is not conducive to sprouting. The temperature is generally high before the rupture of the chest. Immediately after the rupture of the chest, the temperature should be lowered and the temperature of 30°C to 32°C should be maintained. Therefore, soaking the seeds after the end of more than 10 hours after the pile should not be flipped, so that the heat preservation of rice seeds exposed white.
3. Preventing too much water from pouring too much water will result in a lack of oxygen in the valley heap, and it will not be able to satisfy the needs of Breeze's breath. It will produce a wine smell and the chaff will be sticky on the outside, causing budding to be unpleasant, uneven and not strong. To maintain the proper humidity in the valley, generally, the husks on the surface of the valley are not white, and no watering is required. The valleys are always kept in a state of dampness and lightness to meet the requirements for the coordination of humidity and oxygen supply.
4. After the prevention of dew-whitening, it is necessary to check the dew-whiteness in time and check it in a timely manner. It is best to insert a thermometer in the rice seed and check the seed temperature regularly to prevent “burning†from happening at temperatures above 40°C.
5. Anti-Bulging Valley does not exercise rice seeds after the promotion of buds, if sowing hot valley down the field, it is easy to "cold", affecting the rate of pods and strong seedlings. Therefore, after budding, the bud should be diluted for one or two days so that the buds gradually adapt to the environmental transformation.
Mushrooms are the world's largest edible fungus. Mushrooms are composed of two parts, the mycelium and the fruiting body. The mycelium is the vegetative organ and the fruiting body is the reproductive organ. Mushrooms are different from plants. Plants can perform photosynthesis, but mushrooms cannot. Mushrooms are fungi and can be divided into large fungi and small fungi (including epiphytic fungi). Mushrooms have as many as 36,000 species and germinate hyphae from mature spores.
