What are the precautions for planting crops in the cold dew season?

Strengthen field management, apply basal fertilizer early, do shallow water irrigation, dry and wet, mainly wet, remember to cut off water and drought in the later stage.

First, the cold dew to the frost, planting wheat is not panicked.

Now that autumn has begun, the cold dew has arrived, and corn is being harvested in many places, and the empty farmland after harvesting corn is just right for planting winter wheat. "From the cold dew to the frost, the wheat planting is not panicked" that is to say, during the period from the cold dew solar term to the frost fall, it is the best time to plant winter wheat, and it is more appropriate to plant wheat at this time.

Second, the cold dew and thunder sounded, and the drought was one hundred and eighteen.

Then there will be continuous dry weather for a period of time after the cold dew, and farmers know that winter wheat needs water, so this dry weather is not conducive to the growth of winter wheat, which will affect the harvest of winter wheat.

As you know, thunderstorms are common in spring and autumn, and if you hear thunder during the cold dew, it is actually not conducive to the growth of crops.

Third, if the cold dew does not shave onions, the heart must be empty.

Many friends in the planting of green onions, the growth of green onions is not good, and even planted onions are all dead, resulting in this situation mainly for two reasons, one is the time to plant green onions is not selected, although green onions can be planted all year round, but if it is not planted in a greenhouse, it is best to pay attention to the planting time.

It is best to plant in spring and autumn, which are neither hot nor cold, which is more suitable for the growth of green onions. Therefore, it is better not to plane out the green onions before the cold dew season, and for open air planting, it is best to remove them before the cold dew.

The cold dew indicates that the temperature difference between morning and evening is getting bigger and bigger.

During the cold season, different crops have different precautions.

Pay attention to the temperature difference, and the temperature difference should not be too large.

When the cold dew arrived, the crops began to be harvested one after another.

The cold dew indicates that the temperature difference between morning and evening is getting bigger and bigger, an autumn rain and a cold, and a month into winter.

When the weather turns cold, pay attention to the growing plants to protect themselves from the cold and keep warm.

Cold dew is the season for wheat sowing, and it is also the season for soybean and corn harvest.

For farming, it is necessary to keep warm, and the temperature is constantly dropping.

It's time to harvest crops.

Cold dew, crops should pay attention to cold and frost protection.

Artemisia chrysanthemum grows faster in the cool season, and can be harvested when the seedlings are about 20 cm tall.

Heavy fog during the cold dew period will block the sunlight and affect the respiration of crops, resulting in delayed flowering and poor growth of crops; In the cold and dew season, pay attention to the cold and dew wind, because the low temperature will affect the normal process of rice flowering, pollination, fertilization and grain filling. In the cold and dew season, it is necessary to pay close attention to sowing wheat, and ensure that it is sown before and after the frost falls.

The effect of cold dew on crops

1. Affect the respiration of crops

The cold dew season is also prone to fog, long-term fog will block the sun for a long time, hinder the respiration of crops, reduce the storage of carbohydrates of crops, cause some crops to delay flowering, poor growth, and thus affect the quality and yield of products.

2. Affect the growth of late rice

The cold dew season is the normal process of flowering, pollination, fertilization and grain filling of late rice, but the meteorological indicators of cold dew wind to rice damage at this time are different with rice varieties and development periods.

3. Sow wheat in a hurry

In the cold and dew season, North China should pay close attention to sowing wheat, at this time, if there is drought and little rain in the weather, we should try to create moisture and grab moisture to sow seeds, we must ensure that the sowing is finished before and after the frost falls, otherwise it will be difficult to sow seeds if you miss the season.

What can be grown in each different period is different, and what is suitable is also different, and these are related to the change in the weather, thenCold dewWhat vegetables can be grown during the season?
