In the past two years, the chilling cold temperatures and overcast rainy days have brought great difficulties to the early sowing of early rice seedlings. In order to find out a new effective way to prevent rotting seedlings, in the spring of 1976, we used fine sand to raise seedlings and greatly reduced Rotten seedlings, the trial initial success. Re-testing in 1977, further confirmed that this method of raising seedlings good effect, planting seedlings rate of 85 Tuo above, than the water sowing seedling maturity 3-5 days, an increase of 60 to 70 kg. The specific practices are as follows: a Seedling finishing: fine
