Effects of Low Temperature and Soil Moisture on Physiological Status of Wheat Different plant species and different varieties of the same plant have different resistance to low temperature, and many physiological and biochemical changes occur in the plant at an affordable low temperature, and the formation of cold-resistant genes or antifreeze proteins can be adapted to low temperature stress, but with the With the constant decrease of low temperature and the extension of low temperature time, the plants will die. Therefore, the ability of the plants to recover after being exposed to low temperature stress (greening rate) can be directly judged by their ability to resist cold. In addition, the soil moisture content will also have a serious impact on the return rate of plants. Among them, we can use small meteorological stations to determine changes in several of these parameters to study the effect of low temperature and soil moisture on the rate of return to greening in wheat, or Can use a multi-point soil temperature and humidity recorder. Through experiments, we have found that: After the winter is over the same low temperature, the rate of returning green through the process of slowly increasing temperature is significantly higher than the rate of returning green that suddenly increases to a high temperature. As the temperature decreases, the time of returning to green gradually extends and the rate of returning green decreases. The correlation analysis showed that there was a significant positive correlation between temperature and returning rate, and the correlation coefficient was 0.91. The soil water content was negatively correlated with the returning rate, and the correlation coefficient was -0.18. Whether or not wheat can safely pass winter depends on the cold resistance of the variety (ie, genotype), but it is also affected by other factors such as the external environment and cultivation measures. For the same wheat variety, cold resistance is related to its sowing date, sowing volume and sowing depth, but also related to light, temperature, soil quality and soil moisture, fertilizer application types and how much. In this study, soil temperature and humidity loggers were used to study the method of controlling soil moisture in pots. It was initially proved that soil moisture exceeding 30% would lead to severe rot of wheat in the turning green period; soil moisture was moderate (about 25%) or low (20%) Left and right) is beneficial to wheat turning green and the roots grow vigorously; but when the soil moisture is low, the growth of wheat seedlings is weaker than when the soil moisture content is moderate; but if the soil moisture content is too low, the wheat seedlings will die. As to the extent to which the soil moisture content is low, it will lead to the failure of wheat to return green. Further research is needed.
Calcium ammonium nitrate is a new high-efficiency compound fertilizer containing nitrogen and available calcium. It has the characteristics of rapid nitrogen supplementation and can be directly absorbed by plants. This product is a neutral fertilizer and has an improved effect on acidic soil. When applied to the soil, it won`t cause soil compaction, in contrast it can loosen the soil, increase the plant's resistance to diseases and promote the activity of beneficial microorganisms in the soil. When planting cash crops, flowers, fruits, vegetables and other crops, the fertilizer can prolong the flowering period, promote the normal growth of roots, stems and leaves, brighten the color, and increase the sugar content of the fruits.

Calcium ammonium nitrate is a commonly used ammonium nitrate replacement product at home and abroad which is much safer for storage and transportation compared with ammonium nitrate in case of fire and explosion.
Not recommend to use with Phosphate Fertilizer or compound fertilizer.
Pay attention to moisture-proof during storage.
