1、 How not to sleep

Dormancy is affected by the environment. If it is a continuous low-temperature environment and cannot accumulate nutrients, it will not germinate. The dormancy process is also terminated slowly. After meeting a certain low temperature, it takes a period of warm temperature to sprout and resume growth. It needs 1000-1500 hours of low temperature at 7 degrees to break its dormancy, but it also depends on the specific variety

2、 How to break dormancy

1. Physical sleep breaking method: when the temperature is between 7-8 degrees, it is necessary to cover it with film and add hay outside the shed for heating. Uncover the hay at night and cover it in the morning, which is conducive to some cooling measures such as low temperature at night. It will be treated for about 20-30 days to ensure its cooling demand, and then heat up in the later stage to break the pruning. In addition, after entering dormancy, the temperature can also be detected at night. When it is lower than 12 ℃, spray water on the fruit trees every day at an interval of 40-70 minutes, which can promote germination and break dormancy

2. Chemical sleep breaking method: chemical sleep breaking method uses flour breaking agent to relieve dormancy. There are many kinds of sleep breaking agents, such as mineral oil plus ammonium nitrate or growth regulator, or cyanamide sleep breaking agents. Among them, the use method of cyanamide sleep breaking agent is relatively simple, the effect is also very good, and it is used more
