Effect of low temperature chilling injury on Rice and its Preventive measures
Rice chilling injury means that rice suffers from the influence of low temperature below the lowest critical temperature, which leads to the abnormal growth and development of rice and the reduction of rice yield. According to the different period of injury, it can be divided into delayed chilling injury, obstacle chilling injury and mixed chilling injury. 1. Types and characteristics of rice chilling injury 1. Delayed chilling injury rice in vegetative growth period, sometimes including reproductive growth period, suffers from lower temperature for a long time, weakens the physiological activity of rice plant, delays heading and flowering, and cannot be fully filled.

Chilling injury of peach fruit during storage
Peach belongs to respiratory jump type fruit, which has respiratory peak and poor storage tolerance. It can only be stored for a few days at room temperature, and most varieties can only be stored for 15 days under 0 ℃. The enzyme activity and respiration of postharvest peach fruit are very strong, so the fruit is easy to become soft, rotten at room temperature, low temperature, low oxygen, high carbon dioxide can inhibit beard effect and enzyme activity. Under the condition of 0 ℃, the film bag is used for controlled atmosphere storage, 1% oxygen and 3% carbon dioxide are controlled, and ethylene absorber is applied, which can be stored for 2 months, but attention should be paid.

Storage Technology of Peach, Plum and Apricot
The fruits of peach, plum and apricot (including cherry) all contain hard core, which belong to stone fruit. The fruit development and postharvest physiology have common characteristics. It is because of the hard core contained in the fruit that the growth curve of double S type appears during growth. Peach, plum and apricot fruits have high respiratory intensity and respiratory peak, so they belong to respiratory climacteric fruits, which determines that they have similar storage and preservation techniques. However, with the different species and varieties, the storage and preservation techniques adopted are different. Peach and plum are generally divided into early,

Fertilization measures for preventing chilling injury of Rice
Fertilization cases: in 2006, in Shangzhi City, Heilongjiang Province and other rice growing areas, some rice seedlings encountered low temperatures below 17 ℃ in the early stage of rice growth, resulting in varying degrees of rice chilling injury. In Ningxia and Zhangjiakou rice cropping areas in northwest China, in the late autumn rice growth period, when the temperature dropped to less than 20 ℃ during the filling season, the rice encountered chilling injury, which was very disadvantageous to grain filling. The seed setting rate decreased by 10-20%, and the heavy ones decreased by more than 50%.
