What should I pay attention to after the greenhouse cherry heats up?

Spraying sleep-breaking agent Before the temperature rises, it is best to spray the sleep-breaking agent evenly (cannon is not recommended) and pour enough water, because germination requires high temperature and high humidity, and gradually raise the temperature to keep the temperature at about 25 degrees and the humidity at about 70%;

In the meantime, it is necessary to observe the humidity in the shed in time. When the humidity is insufficient, it is necessary to pour a small amount of water or spray water manually to increase the humidity. Make sure to water twice before flowering, and after heating for 5 days, spray the mixture of stone and sulfur at 5-7 degrees.

After spraying sulfur mixture, Yibainong Wanwu Spring High Phosphorus 10-52- 10+ Yigen or Basic nutrition package can be applied or dripped to promote the rapid germination of root meristems and flower buds. It is suggested that the second watering must be early to avoid delaying the flowering period.

Extended data:

Always keep the temperature and humidity in the greenhouse before flowering, so we must pay attention to the occurrence of red spiders. If red spiders occur, we must prevent them in time;

In previous years, if fruit shrinkage or serious fruit drop occurred in greenhouse 5-7 days before flowering, it could be prevented by spraying Yibainong Yizhou boron. Spraying Yizhou boron can not only prevent fruit shrinkage and drop, but also increase pollen tube elongation and improve pollination fruit setting rate.

When most buds are white, a single fruit tree blooms, so PBO can be sprayed. Before spraying, you must mainly look at the weather forecast, because there will be a lot of flowers, because cloudy days will have an impact on insect pollination.
