First, the basket Sheng Sheng germination method
1. Soaking Seeds of hybrid rice before sowing, first with yellow mud water, etc. to select seeds, remove empty pods, cracked shell granules and smut diseased grains, and then fully rinse with rice water. Finally, the cleaned rice seeds are soaked in clean water and combined with disinfection. Soaking time is generally about 3 days, once a day for fresh water or daily immersion night dew, soaked to the color of the husk darken, soaked embryos, through the husk can be clearly distinguished when the embryo and endosperm required soaking. Prevent insufficient soaking or excessive soaking.
1 cleaning. Soak the soaked seed valleys with clean water until no turbid water is agitated. In this way, the viscous fermentation product formed on the chaff during the soaking process can be removed and the air permeability of the chaff can be improved, so that the sour taste and wine taste of the seed valley can be prevented during germination, and the disinfectant remaining on the seed shell can also be washed away.
2 drain. Put the washed seed valleys in the baskets, drain them for 2 hours to 4 hours, drain the clear water on the surface of the chaff, and allow the air to enter the chaff, which will act as a drain to increase oxygen and promote germination.
3 warm up. Pour the drained seeds into a bucket or pot containing 50°C hot water and bath for 15 minutes to 30 minutes. Stir quickly when it is poured in, and stir it once every few minutes to fully and evenly preheat the seed valley. If the water temperature drops below 35°C during preheating, add a small amount of hot water with a temperature of about 50°C and stir it so that the water temperature in the preheating process is always maintained at 38°C to 40°C, ensuring the preheated seed valley temperature It reaches 35°C to 38°C. If there is a small amount of hot water in the bucket and no heating water is added in the middle, the water temperature can be reduced to 35°C or less within a few minutes. If the preheating is terminated at this time, the preheating time is too short, making the Valley of Grain “outside. "Inner cooling," the valley temperature will drop rapidly and it will be difficult to maintain between 34°C and 38°C.
4 stack (into the basket). Remove the preheated seeds and put them in a clean basket or small sieve. At the same time, select a free, sheltered corner in the room, lay 15 cm to 20 cm thick hay on the ground, put a tub on the grass, fill the basin with hot water of about 50°C, and put a wooden stand on the pot or Horizontal sticks. Lastly, the baskets with the seed-filled grains (hereinafter referred to as the germination baskets) are placed flat on the wooden racks of the hot water basins, a layer of plastic film is covered on the germination baskets and the hot water basins, and the outside is covered with hay or old cotton and other insulation.
Note: 1 Use the steam in the basin to keep the trough temperature between 34°C and 38°C. The seed valley can be broken by 16 hours to 20 hours. As the number of seed valleys is small, the heat preservation during the germination process is poor, and as the water temperature in the basin gradually decreases, the valley temperature gradually decreases. When the valley temperature is lower than 34°C, the lower temperature water in the basin should be taken out in time and a suitable amount of boiling water should be added at the same time. The water temperature in the basin should be raised to 50°C again, but the water temperature in the basin must not exceed 50°C. Heat burns the seed valley. If the valley temperature is higher than 38 °C, the cover should be appropriately reduced or heat radiated. After the two kinds of valleys broke the chest, the cover was appropriately reduced and the seeds were turned over so that the valley temperature decreased and maintained at 28°C to 34°C. After about 20 hours to 22 hours, a vigorous shoot could be obtained to achieve the germination standard. The method for adjusting the temperature and humidity of the seed valley in this period is the same as above. However, at this stage, while ensuring sufficient water supply, it is necessary to step up the planting process, timely adjust the temperature and ventilation, and prevent the high-temperature burning and oxygen deficiency from causing alcoholism. 3 The buds will be spread on the indoor bamboo mat spread, a small amount of warm water about 20 °C, spread drying 2 hours to 4 hours to sow. If the seedlings cannot be planted in due time due to the lack of good conditions in the Yutian farm (seedling bed) or in case of cold weather, etc., if it is necessary to extend the airing time, wet towels should be covered on the grain buds, and the water should be moistened and moistened timely to prevent the root buds from wilting. This has led to a decline in the vigor of buds that have been promoted, and even to loss, which in turn affects the rate of success and the quality of seedlings after sowing.
Second, when the bag is filled with germination method, if the bag is replaced with a bag with good air permeability, gauze bags, cotton cloth bags, linen bags, etc. (but not plastic woven bags) can be used to dress the seed valleys for germination. It also simplifies the overturning of the pods in the process of germination, and prevents the mechanical damage (breakage) of radicles and germs caused by overturning. The specific approach is: Put the preheated seed grain into a clean bag and tie the bag mouth. Note that the seed grain can only be loaded to about 1/2 of the bag's volume. Then, the bag with the seed-filled grain (hereinafter referred to as a germination bag) is pressed into a flat shape to reduce the thickness of the seed grain and prevent the occurrence of high temperature and lack of oxygen in the bag heart during germination. Finally, flatten the germination bag flat on the wooden stand of the hot water basin and cover the insulation. At this point into the germination stage.
Precautions: In the stage of sprouting at high temperature and proper temperature and humidification, due to the uneven temperature and humidity in the germination bag (mainly between the upper and lower), whenever the seeds need to be turned over, they only need to turn the flat germination bag upside down. can. When the top of the bag is obviously dry and the water is whitish, there is no need to unravel the water from the bag mouth. Simply pour warm water from the outside onto the bag and dry it so that it can naturally infiltrate. The method of temperature adjustment in the bag germination process is the same as the method of germination and germination in the basket.
Third, the barrel Sheng Sheng germination method In order to use the bag Sheng Sheng germination advantages and to simplify the insulation measures, can be used bucket barrel germination method. Two plastic buckets or plastic basins of slightly different sizes or sizes are stacked to make use of the air interlayer formed between the buckets or the basins (the thermal conductivity of the air is minimal). In a bucket or pot, there is half a barrel (pot) of hot water at about 50°C, and then a few wooden sticks are used to support the germination bag. Then place the germination bag with seed corn on the wooden stick. Note that the lower part of the bag should not touch the water surface, and the upper part should not expose the barrel mouth. Finally, a piece of plastic film or old cotton batting is placed on the bucket and placed in a warmer part of the room, such as by the stove or in the haystack. At this point into the germination stage.
Note: The management method of temperature, humidity, etc. during barrel germination is the same as that of bag germination. This method is due to the smaller volume of the bucket, so the number of seeds should not be too much.
