What is the saying about cold dew and rain (a good sign of autumn harvest)

Cold dew is the sixteenth of the twenty-four solar terms, which generally appears on 10 year 10 on July 7 or 8, indicating that the temperature is gradually decreasing and the weather is getting cold. Cold dew rain is a common meteorological phenomenon, which is of great significance in agricultural production. According to the experience of traditional farmers, cold dew and rain are good omen for autumn harvest.

The benefits of cold dew and rain

The benefits of cold dew rain on autumn harvest mainly include the following points:

1. Replenish soil moisture

In autumn, the temperature gradually decreases, and the moisture in the soil gradually decreases. Cold dew and rain can replenish the water in the soil in time to ensure the water needed for crop growth.

2. Promote crop growth

Rainwater contains a lot of nutrients such as nitrogen, phosphorus and potassium, which can provide sufficient nutrition for crops and promote their growth. At the same time, rainwater can also clean the dust and impurities on the surface of crops and maintain the healthy growth of crops.

3. Increase crop yield

Cold dew and rain can increase crop yield. Because the nutrients of rainwater can provide sufficient nutrition for crops, at the same time, rainwater can also clean the dust and impurities on the surface of crops, maintain the healthy growth of crops, and thus improve the yield of crops.

How to use cold dew to rain

For farmers, how to maximize the benefits by using cold dew and rain dew? Here are some steps:

1. Drainage in time

Although cold dew and rain are beneficial to crop growth, too much rain can also cause harm to crops. Therefore, farmers need to drain water in time to ensure that the roots of crops are not soaked in water.

2. Strengthen fertilization

Cold dew and rain can provide sufficient water and nutrition for crops, but because the nutrients in rain are relatively single, farmers need to strengthen fertilization to provide more comprehensive nutrition for crops.

Timely selection

After cold dew and rain, the growth rate of crops will accelerate, and farmers need to pick them in time so as not to affect the quality and yield of crops.
