Experience in preventing cold for spring rice seedlings

(Baonghean.vn) - Currently, localities are focusing on sowing seeds for spring crop production. However, besides localities that have done a good job of preventing and protecting seedlings from cold, in some districts, people still have yellowing of seedlings, even death due to not strictly following the recommendations of the Department of Agriculture.

The weather is still cold and rainy and according to forecasts, there will still be some severe cold spells occurring over a wide area. Localities need to resolutely direct people to properly implement the following measures to prevent and protect rice seedlings from the cold:

For sown seedlings, the water level must be kept at 2/3 of the furrow surface to keep the seedlings warm. Regularly change the water in the furrow, add ash, and cover with plastic properly (when the seedlings grow evenly, if the temperature is above 15 degrees Celsius, open the plastic at both ends of the furrow at noon and cover it again in the evening. If the weather is cold below 15 degrees Celsius, continue to cover the furrow).

With the green rice seedlings, you can use additional foliar fertilizers to help increase the resistance and cold resistance of the seedlings, and to help the seedlings grow strong and root well before transplanting.

According to the recommendation of the Department of Agriculture, the late spring sowing season will last until 25/2012. It is necessary to ensure that the entire area is sown on small beds (bed surface is 1.2-1.5m wide) to be covered with plastic. In places with conditions, it is recommended to sow on hard ground covered with plastic to prevent cold damage. Warm water (28-30 degrees Celsius) can be boiled to water in the afternoon when the dew has melted.
