Last Updated: 2024/11/22, At present, some early sowing areas are affected by the rapid change of temperature of the cold current, rice seedlings have been frozen to varying degrees, which has affected the management of rice field, and will postpone the process of transplanting rice seedlings to a certain extent. In order to do well the seedling field management and reduce the harm of low temperature, the technical suggestions of seedling bed management are put forward. 1. Raising seedlings in small shed. According to the weather forecast, the mulch should be added to the shed, closed and insulated. In case of frost, candles or smoke can be lit in the shed to increase temperature and prevent frost. In raising seedlings in the greenhouse, ventilation should be reduced or even not ventilated, and grass curtains should be surrounded by grass curtains and plastic film should be laid in the shed.

At present, some early sowing areas are affected by the rapid change of temperature of the cold current, rice seedlings have been frozen to varying degrees, which has affected the management of rice field, and will postpone the process of transplanting rice seedlings to a certain extent. In order to do well the seedling field management and reduce the harm of low temperature, the technical suggestions of seedling bed management are put forward.

1. Raising seedlings in small shed. On the shed, according to the weather forecast, add mulch, airtight heat preservation, in case of frost, you can light candles or smoke in the shed to increase temperature and prevent frost; in raising seedlings in the greenhouse, ventilation should be reduced or even not ventilated, grass curtains should be surrounded, and plastic film should be laid in the sheet. and can be used at night 1-2 pot fire or smoke to increase temperature.

2. The management of seedling bed should be strengthened for frozen seedlings. Cool water to slow seedlings before sunrise, after sunrise, the bed should be covered with grass to prevent strong light and avoid temperature rising too fast or high temperature aggravating cold injury, do not cover the seedlings at high temperature.

3. Strengthen the management of seedling field. It is not only necessary to prevent the breeding of weak seedlings from too high temperature in the greenhouse, but also to prevent the breeding of young and old seedlings from low temperature and lack of water, but also to prevent drastic changes in temperature from causing green and blight to cause dead seedlings.

According to the experiment, spraying nano-magnetic energy liquid at rice seedling stage has a significant effect on cold resistance, anti-freezing and strong seedlings.

For the seedlings that have been frozen, nanometer magnetic fluid can also be sprayed, which can effectively alleviate the freezing injury and restore the normal growth of seedlings in a short period of time.
