Experts remind: beware of frost in autumn harvest, how to prevent frost?

Paying attention to weather changes, grabbing crops before frost, grabbing seeds in time, raising ground temperature, strengthening internal management of greenhouses and paying attention to temperature changes are all good ways to prevent frost disasters.

Autumn harvest is in full swing everywhere, and many places have entered the final stage, but at this time, cold air keeps coming, and frost may appear in many places. If frost weather comes, it will hurt crops in farmland and affect the yield and quality of crops. Therefore, during the period before the frost comes, we should pay close attention to the weather changes in time, strive to grab the crops in the field before the frost comes, and try our best to return the particles to the warehouse.

Pay attention to the weather changes, know when the frost will come, grab the grain and vegetables in the field before the frost occurs, and store them in a safe place, so that the annual harvest will be settled, and when the frost occurs again, the vegetables and crops in the field will not be harmed, and the income of farmers will not be affected. This is also an effective way to deal with double actions in time. Late rice and hybrid rice need to be planted in some areas. At this time, the seeds should be planted in time before the frost occurs. Even if frost occurs, seeds or seedlings will not freeze to death, but sowing will be late after frost, and solar terms will affect their maturity.

In order to prevent crops from freezing injury, it is necessary to water crops frequently and keep the soil moist, because moist soil dissipates heat slowly and high temperature will not affect crops in the field, while when the soil is dry, it dissipates heat quickly and crops are greatly affected by frost. In some places, smoke can also be used to form insulation clouds in a small area, which can also reduce the occurrence of freezing damage and reduce the harm of frost to crops.

Before the frost occurs, you can often hoe and loosen the soil, which can also increase the ground temperature and prevent the ground temperature from dropping rapidly when the frost comes, which will affect the growth of crops. People who plant greenhouses must strengthen the internal management of greenhouses to prevent the temperature in greenhouses from plummeting when frost comes, which will affect the vegetables and fruits in greenhouses. In first frost, tomatoes, cucumbers and eggplants in greenhouses were in a vigorous growth period. At this time, we must strengthen the work of heat preservation and cold protection, water in time and harvest in time. Doing these things well can effectively prevent frost, adversely affect field crops and minimize the losses caused by frost.
