What is the key technology to popularize buds?

According to the requirement of temperature for seed germination, the key to promote germination is to master high temperature breast breaking, suitable temperature germination and low temperature drying.

(1) High-temperature chest-breaking is to soak the seeds that have absorbed enough water in warm water at 50 ~ 60℃ for 3 ~ 5 minutes, and then put them in a cellar to keep them at 38 ~ 40℃, so that the seeds can be broken at high temperature (38℃) and germinate quickly and orderly at higher temperature.

(2) Proper temperature to accelerate germination means that after the seeds break the chest, the respiration of rice increases rapidly, producing a lot of heat energy, and the temperature will rise rapidly. At this time, it is necessary to turn over the pile, spray water to cool down and dilute the seed pile to keep the seed temperature at a suitable temperature of 25 ~ 30℃ to facilitate germination. The water spraying temperature should not be too low, and it should be gradually reduced to about 25℃ to keep the seed pile moist and keep oxygen.

(3) Normal temperature tempering means that when the buds reach the standard, they can be tempered at normal temperature to enhance their adaptability to the environment of the seedling farm. If hot seeds are planted in the ground, the young buds are stimulated by sudden cooling, and it is easy to produce dead buds. The best time for bud refining is that the seeds have cooled down. This requires a good coordination between germination and seedling raising. Generally, it is piled on the first day, broken the next day, germinated in the morning on the third day, and can be dropped in the afternoon. In case of rain or cold current, the germination time can be extended, and the seeds can be sown when the tail is cold and the head is warm.
