How to protect flowers and fruits of potted apricot?

Potted apricot trees bloom earlier, which is easy to affect the fruit setting rate due to late freezing injury. In order to avoid late freezing injury, the following measures are usually taken:

1, select cold-resistant varieties.

Choose varieties with late flowering and strong cold resistance, such as Xing Li in Liquan, Shaanxi or Baimeixing in Yongji, Shanxi.

2. Postpone flowering

In early spring, methods such as watering the basin soil, covering the basin surface with grass and painting the trunk white were used to control the heating rate and delay flowering. Generally, the flowering period can be delayed by about 5 days, which can avoid freezing injury.

Step 3 spray medicine

Spray 0 at the stage of flower bud expansion. 05%~0。 2% Mh (1 times) can delay the flowering period by 4 ~ 5 days.

4. Smoking

According to the weather forecast, when there is danger of late frost, stacking firewood and smoking in the potted garden in the morning can also reduce the frost hazard.

Although the self-pollination rate of apricot is high, in order to ensure the fruit setting rate of potted trees, artificial pollination or bee pollination is carried out at flowering stage, and 0 is sprayed every 3-5 days at full flowering stage. 1% borax +0. 1% urea 1 ~ 2 times can obviously improve the fruit setting rate.
