In the bitter cold of late spring, the smoke in the orchard is resistant to frost damage, but experts say that smoke pollutes the environment, how to choose? In the coming late spring cold, the use of smoke to improve the local microclimate of crop planting areas, form a small-scale greenhouse effect, reduce the sinking of cold air, and affect crops, which can play a certain role in cold protection and warmth. This method is a relatively effective method summarized through the long-term process of people's cold protection and warmth.
It is economical and low-cost, easy to operate, simple and convenient, and can be made from local materials. As a result, the smoking method is popular with many fruit and tea growers. It is mentioned in the cold protection measures of orchards and tea plantations, and it is also widely used in practice.
But some experts say that smoke can have an impact on the environment. From a practical point of view, smoke does produce thick smoke, which has an impact on the environment. But because of the smoke, we can't fight the cold with smoke.
It's like factory production produces a lot of pollutants, but in order not to pollute, production cannot be allowed. Cars emit a lot of exhaust gases every day. You can't drive without it.
So it's a matter of degree, and the fumigation method is also a local, small-scale case. It can't be nationwide or massive. It won't be long.
Every spring from March to April is a cold day. It is still used by genuine cars. If you lower the temperature a little and there isn't too much cold in late spring, you probably won't need to smoke the smoke.
So I think it's a good option for farmers. But for many experts, this may not be a good option. It does exist.
In some areas, the management of fumigation is so strict that you can't use it at all. This should be based on the actual situation in each place. Here's my take on the issue.
I think it's okay for farmers to use the method of fumigation, it's not too damaging to the environment, it's not very serious, and it's for a short period of time.
-
It is true that igniting the smoke can do this because it prevents temperature loss to a certain extent.
-
I think it is necessary to take certain measures to protect the environment, after all, the environment is very important now.
-
This is mainly about the fruit, after all, this planting is also very hard.
-
It depends on the actual situation, and it is necessary to distinguish between the advantages and the disadvantages.

In order to prevent the cold in spring, can fruit trees be smoked to protect against the cold?
Spring is the transition season from winter to summer, cyclone activity is frequent, the weather is changeable, the temperature rises faster in early spring, and the temperature often plummets below 10 in the late spring, and even rain and snow weather, which is often called the inverted spring cold.
A late spring cold will hit fruit trees such as apricots, apples, pears, plums, cherries and other fruit trees that bloom early, especially in low-lying orchards, every year.
The cold spring in March and April had a greater impact.
It is easy to freeze buds and freeze flowers, which directly affects the flowering, pollination and fruit setting of fruit trees, and causes great damage to fruit trees. At present, while doing a good job in epidemic prevention and control, it is also necessary to do a good job in orchard management, timely carry out preparations for the prevention and control of spring cold, prevent problems before they occur, and ensure that this year's apple harvest is high quality.
"Falling spring cold" is harmful to all fruit trees, especially those that bloom early. to teach you how to prevent it.
The following prevention and control measures should be taken on the basis of reasonable fertilization, irrigation and branch pruning, and overwintering management:
b1.Watering. For orchards that are prone to spring cold, if there are irrigation conditions, water 1 or 2 times before and after germination to reduce ground temperature, delay budding, and avoid spring cold; Spray with salt water.
2.Pay attention to the weather forecast and spray the tree with 10% 15% salt water before the onset of low temperature frost damage. In doing so, frost resistance can be achieved by increasing the concentration of the somatic cell sap of the tree; Through water vapor condensation and heat release, the frost damage of the tree can be reduced;
3.Smoking. When a cold snap arrives, smoke in the orchard as soon as possible: preferably at night when the temperature drops to 0. 6 7 dry branches and weeds are stacked per mu, and the soil is pressed after burning to improve the smoke effect;
4.Spray fertilizer. Before the onset of frost damage, spraying potassium dihydrogen phosphate aqueous solution on fruit trees at the budding stage can increase the cold resistance of the trees and reduce the frost damage.
The terrible thing about the cold in spring is that it is warm first and then cold, and the warm weather makes the fruit trees wake up, sprout and flower, and at this time, the frost resistance is extremely weak, and the frost damage may lead to all the hard work in vain. In the event of a disaster during the flowering period, the flower buds will fall off, the yield of apple trees will be reduced or extinct, and the shoots, leaves, and stems will be frozen and damaged, and even the trees will die. In the young fruit stage, the frost will cause the fruit to be deformed, slow to develop, and even if it can mature, the skin will be wrinkled and difficult to survive, and the tree will lose its economic value, and the tree body will be damaged.
-
No, because the smokehouse is not suitable for fruit trees, many fruit trees will harm it during the smoking process, and the buds that grow in spring are easy to affect the normal growth of fruit trees, and will also affect the fruiting rate of fruit trees in the current year.
-
Yes, this is also a measure commonly used by people to prevent winter cold, and it can also play a certain role in keeping warm and preventing plants from freezing to death.
-
Yes, this will also protect the fruit trees from the spring cold, and also prevent the trees from getting frostbite in the spring.
-
Probably not, smoke produces a lot of harmful gases, which will only accelerate the withering.
-
This is possible, with smoked fruit trees, it can raise the temperature of the soil.
