Last Updated: 2024/11/22, 1. Irrigation before flowering in apricot about 10 days before flowering can reduce the ground temperature, increase air humidity, delay flowering for 4 days, and help to avoid the harm of late frost. two。 Special attention should be paid to frost forecast at flowering stage. When frost is predicted, the method of smoking should be taken in time to prevent frost, that is, the sundries such as straw and fallen leaves should be lit before Frosts Descent, so that the smoke will cover the whole apricot orchard and the temperature can be increased by about 2 ℃. Aerosols can also be used, with a formula of 20% ammonium nitrate, 15% waste diesel, 15%

1. Irrigation before flowering in apricot about 10 days before flowering can reduce the ground temperature, increase air humidity, delay flowering for 4 days, and help to avoid the harm of late frost.

two。 Special attention should be paid to frost forecast at flowering stage. When frost is predicted, the method of smoking should be taken in time to prevent frost, that is, the sundries such as straw and fallen leaves should be lit before Frosts Descent, so that the smoke will cover the whole apricot orchard and the temperature can be increased by about 2 ℃. Aerosol can also be used, the formula is 20% ammonium nitrate, 15% waste diesel oil, 15% coal noodles and 50% sawdust or grain chaff, straw powder, dry horse dung, etc., stir evenly into Kraft paper bags to compact and seal. Each bag is 1.5kg, can release smoke for 10-15 minutes, and control area is 2000-2700 square meters.

3. Artificial pollination and artificial pollination of several apricot varieties at flowering stage, or release of horned frontal wall wasp, @ # @ 255cm, etc., can significantly increase the fruit setting rate.

4. Spraying water or boron during flowering period is dry in spring, and the adhesion of stigma on apricot flower is poor, which is disadvantageous to pollination. Spraying water or boron (0.1%-0.3%) is beneficial to pollen adhesion and germination, and can increase the fruit setting rate.
