Before winter comes, we always like to wear protective clothing for crops, but when winter is really coming, are you ready? How do fruit trees and vegetables face this situation? How is it to protect the cold?
Cold damage is an agricultural meteorological disaster that is in the growing season of crops. Cold damage can destroy the physiological activity of crops, thereby destroying the growth organization of crops. With the concern of cold damage, farmers are paying more and more attention to such disasters.
According to the plant's resistance to low temperatures. And with the continuous low temperature weather, how should we respond to prevent crop diseases?
First understand the causes and symptoms of freezing damage
Continuous low temperature
(1) Root freezing damage
(2) Rhizome freezing damage
(3) Twig freeze damage
Crop cultivation time
During the transplanting period, especially in the autumn, the trees that are already in the fall are more susceptible to freezing damage, and the roots are vulnerable to damage. However, compared with the older trees, the cold resistance is relatively strong, but also pay attention to prevention.
How to deal with low temperature, a few tricks:
I. Increasing the application of organic fertilizer, improving soil fertility, covering with straw, planting grass ash or chaff in the field to protect the seedlings, increasing the application of farmyard manure, using the cultivated land after the disaster to grow green manure, and increasing the content of soil organic matter.
Second: strengthen water and fertilizer integration according to crop growth and soil combination, reasonable irrigation and water conservation
Third: the use of plant antifreeze plant antifreeze is mainly to improve the ability of crops to resist freezing, effectively prevent frost invasion and reduce frost damage. The plants that are frostbitten also have a certain ability to repair, so that the crops grow normally.
By learning to understand the causes and symptoms of freezing damage, we must also make judgments based on actual conditions, and choose appropriate and reasonable methods to deal with freezing damage to ensure a good harvest.
