1. Choose a good variety. The varieties with high complete flowering rate, strong self-fertility, and early fruit production were selected as the main plant apricot varieties such as Kate apricot, Golden Sun, New Century, Hongfeng, etc., and the fruit set rate was high. 2. Auxiliary pollination. Artificial methods such as pollination and bee pollination may be adopted. Artificial Pollination: Pollen can be collected manually and given with a brush or eraser. To ensure that flowers in different flowering stages are fully pollinated in time. Putting bee pollination: Apricot gardening bees or horned wall bees can significantly increase fruit set. A box of bees in each greenhouse can basically meet the needs. In addition, spraying 0.3% borax during flowering can promote pollen germination, increase flower organ nutrition, and increase fruit setting rate. 3. Strictly regulate temperature and humidity. The adjustment of temperature and humidity in the facility should avoid high-temperature germination and high temperature during flowering. During the flowering season, the temperature during the day should not exceed 23°C. In other days, it should not exceed 28°C and the nighttime temperature should not be lower than 5°C. If the temperature is too high, the air should be released in time to cool down, otherwise insulation measures should be taken. When flooding, avoid flooding, and reduce the humidity by ventilation and covering the film. Watering as little as possible during flowering, when it is very dry, watering a little, drip irrigation is better. Water is controlled after the fruit is colored to promote coloration and maturation. 4. Apply more organic fertilizer. After removing the shed film, before the shed is divided into two fully applied organic fertilizer, it is necessary to give more, give enough, in order to promptly add tree nutrients, restore and enhance tree vigor, reduce the formation of degenerative flowers, improve flower bud quality. 5. Reasonably trimmed. After going to the film, trim and retreat. When cutting in winter, adjust the amount of branches and flower buds. After the shed, when the new shoots grow to 20 centimeters in time, they pick their hearts in time to control the growth of new shoots and avoid shoots and flowers competing for nutrients. 6. Improve lighting. Try to improve the light in the shed. If the temperature permits, expel as soon as possible, and if it is not snowy, use scattered light. Use drop-free film and spray with water drops before use. Clean or clean the film in time. Control the height of southern plants to avoid shading.
