2018/2019 will be cold winter? What effect is good for antifreeze for crops? Regarding the winter climate trend of 2018/2019, the National Climate Center has a preliminary prediction conclusion: It is expected that the temperature in most parts of China will be high in winter and cold winter. It is unlikely. According to the National Climate Center, since June 2018, the sea surface temperature in the equatorial central and eastern Pacific has turned warmer and has continued to grow. This warming will continue to develop and an El Nino event will be formed in the winter of 2018/2019. When the El Nino incident occurred, the East Asian winter monsoon intensity was weak, and the temperature in China was generally high.
The cold dew has passed, the autumn is getting stronger, and the weather has continued to cool in recent days. Some areas have rain and snow. Xiaobian here is to remind the majority of growers: the national cooling moment is coming, the crops should be prepared to “anti-freezeâ€! The main points of anti-freezing: the prevention of freezing damage is good, the loss will be less! If it has been frozen, it will cause frostbite Losses are hard to avoid. In order to minimize losses, everyone must cultivate the habit of early prevention.
The freezing damage of crops is generally because the crops are in a sub-health state, and the low temperature is likely to cause cell wall and cell membrane rupture. Therefore, timely supplementation of crop nutrition, making crops more robust, in order to achieve better resistance to freezing damage, to ensure rapid recovery after freezing is critical.
This point is said to be like a human being. A healthy person's virus is not easy to invade, and some people are weak. As long as the temperature changes slightly, it is not a cold or a fever. In the final analysis, the body is not good, and crops are the same.
Antifreeze program:
In order to make crops robust, it is inevitable to supplement phosphorus and potassium.
The following small series introduces an antifreeze program. If the crop is healthy and not too long, it is impossible to supplement the phosphorus and potassium. Therefore, in the winter, more potassium dihydrogen phosphate is used for crops, which can prevent the freezing of winter crops and the weak leaves of plants. In winter, the temperature is low, the crops absorb nutrients slowly, and proper adjustment of the crop is also critical. Especially after recovery from freezing. Regulators Xiaobian recommended brassinomycin.
Potassium dihydrogen phosphate and brassinolide are perfect match.
This product, which may have been eliminated by many manufacturers and distributors, is actually the most cost-effective antifreeze package. Brassinolide can regulate the endogenous hormone balance of the crop itself, enhance the resistance of the crop, and achieve the effects of cold resistance, drought resistance, mites and disease resistance. It can also alleviate the damage of plants and help the crops recover quickly.
In addition, as for the anti-freezing in the greenhouse, it is also possible to cool down the shed to release the smoke to achieve physical protection. However, everyone should pay attention to safety and don't burn the shed.
Let’s talk about the 2018 issue about cold winter.
As the seasons change, the cold air in autumn and winter is becoming more active, and the public is more concerned about the climate predictions this winter. There have been more rumors about the "cold winter" on the Internet, and even the saying "2018 is cold winter, and from now on until 2025, the temperature is colder than one year a year". In response, the National Climate Center said that the above-mentioned statement is very ridiculous, in order to attract public attention and create public panic.
In addition, winter temperatures in China are synergistically affected by the circulation systems of the East Asian winter monsoon. The climate models at home and abroad consistently predict that the overall Eurasian atmospheric circulation in the winter of 2018/2019 will be dominated by zonal type, which is not conducive to the frequent activities of cold air, which is conducive to the wide temperature range in China. And as the timeliness of the forecast approaches, the forecast results of the various models are revised to a larger warming trend than before.
It should be noted that the warm winter in the climate means that the average temperature in the whole winter is high. It is not that there is no strong temperature drop and heavy snow and blizzard weather in this winter. On the contrary, the warm winter weather encounters a sudden cold weather process, and the winter crops have lower cold resistance and are more susceptible to unexpected damage.
Therefore, farmers’ friends should pay more attention and take countermeasures.
1. Early application of phosphorus, potassium, boron fertilizer and winter ash, fire-burning soil or soil-fertilized fertilizer and fermented pig manure and other warm fertilizers, increase soil temperature, improve plant cold resistance, and cooperate with spraying foliar fertilizer Improve the soil, promote the growth of the plant and improve the cold resistance of the crop itself.
2. Coverage, trunk dressing, root neck soil and other crop protection.
3. Before the freezing, the drought is serious, and the water can be permeated once before the cold; in case of freezing weather, the condition can be refilled once, or weeds, chaff, sawdust, dried leaves or other smoked materials are piled up in the crop land. Smoke the smoke or spray antifreeze to protect the crop.
4. Timely cultivating the soil, making the soil loose and breathable, doing a good job of clearing the ditch, so as to facilitate the growth of the root system, timely remove the frozen dead plants and yellow leaves and dead leaves, and effectively prevent and control various pests and diseases in winter to ensure the crops start spring. After strong growth.
