Pomegranate flowers bloom in which month?
Do you know this? The knowledge about the flowering time of pomegranate flowers in the field of green plants and flowers, let's learn about it together below.
Pomegranate flowers usually bloom from late May to early July, and the specific flowering period is significantly affected by climate, variety, and cultivation conditions. As a perennial shrub with both ornamental and edible value, the pomegranate tree has a cultivation history of over 2000 years in China. Its flowering patterns and horticultural management directly affect fruit yield and landscape effects. The following is a comprehensive analysis from three dimensions: flowering characteristics, influencing factors, and planting suggestions.
I. Flowering Characteristics and Regional Differences1. Main flowering period: Under natural conditions, pomegranate flowers bloom from the end of May to the beginning of July, with a peak flowering period of about 20-30 days. There are significant differences in different regions:- Yellow River Basin: May 20th to June 20th (Zhengzhou, Xi'an, etc.)- Yangtze River Basin: May 15th to July 5th (Wuhan, Nanjing, etc.)- South China: Late April to mid-June (Guangzhou, Nanning, etc.)2. Flowering characteristics: Pomegranate flowers coexist with bisexual flowers and sterile flowers, including:- Trumpet-shaped flowers (fruit-bearing): Corolla diameter 3-5cm, borne on the top of fruiting branches- Bell-shaped flowers (sterile flowers): Account for more than 70% of the total, naturally fall off after floweringThe flowering period of a single plant can be divided into three stages: initial flowering (5% of flowers open), full flowering (75% open), and late flowering (remaining 20%).
II. Key Variables Affecting Flowering Period1. Meteorological factors:- Accumulated temperature effect: Daily average temperature ≥15°C for 10 consecutive days triggers flower bud differentiation- Precipitation impact: Continuous rainfall during the flowering period can reduce the pollination rate by 40-60%- Extreme weather: High temperatures above 30°C can shorten the flowering period of a single flower by 3-5 days2. Variety differences:- Early flowering varieties (Hongruyi, Taishan Hong): Begin flowering at the end of April- Mid-maturing varieties (Daqingpi,Lintong石榴): Flower in mid-to-late May- Late flowering varieties (Yunnan Crystal, Tunis Soft Seed): Begin flowering in June3. Cultivation management:- Pruning intensity: Heavy pruning can delay flowering by 7-10 days- Water and fertilizer control: Controlling water before flowering can promote concentrated differentiation of flower buds- Plant hormones: 50ppm gibberellin treatment can advance flowering by 4-6 days
III. Key Points of Flowering Management Techniques1. Flower promotion measures:- Autumn application of base fertilizer: Apply 15-20kg of decomposed organic fertilizer plus 1kg of superphosphate per plant in September-October- Winter pruning: Retain 45-60cm fruiting parent branches, thin out dense branches- Spring supplemental lighting: Ensure 6 hours of direct sunlight per day starting from March2. Flower protection plan:- Artificial pollination: Collect pollen daily from 9-11 am during the full flowering period- Application of anti-abortion agent: Spray 0.1% naphthalene acetic acid solution during flowering- Water management: Maintain soil moisture content at 60-70% (i.e., the soil holds together without dripping water)3. Handling common problems:- Severe flower drop: Check for phosphorus deficiency (foliar spray of 0.3% potassium dihydrogen phosphate)- Early flowering: Caused by insufficient day-night temperature difference in winter, control temperature at 0-7°C for 800 hours- Secondary flowering: Remove in August-September to ensure the development of main fruits
IV. Development of Ornamental and Economic Value1. Landscape application:- Flowering period regulation: Extend the ornamental period to over 90 days through variety combination- Sculpting techniques: Can be trained into 3-5m high flowering shrubs or less than 1.5m high potted landscapes2. Market data:- Fresh cut flower price: Wholesale price during the full flowering period is 8-15 yuan per stem- Pollen production: Adult trees produce 50-80g of dry pollen per year- Nectar value: Each mu of pomegranate garden can support 5-8 boxes of bees for collection3. Combination of agriculture and tourism:- Best viewing period: 3-7 days after the full flowering period (flowers fully open)- Supporting activities: Can carry out flowering photography, pomegranate flower tea making experience, etc.
By mastering the flowering patterns of pomegranate, growers can achieve accurate flowering period management through variety selection and environmental regulation. In the north, it is recommended to choose late flowering varieties to avoid late spring frost, while in the south, attention should be paid to shading in summer to extend the lifespan of individual flowers. In actual cultivation, it is necessary to establish a phenological observation record, and data from 3 consecutive years can accurately predict the local specific flowering period.
