How to set watermelon fruit: analysis of hot topics and planting tips on the Internet in the past 10 days
Recently, as summer approaches, watermelon planting has become a hot topic. This article will combine the hot content of the entire Internet in the past 10 days to analyze the key technologies for watermelon fruit setting and provide structured data reference.
1. Hot topics on watermelon planting on the Internet in the past 10 days
| topic type | heat index | Main discussion points |
|---|---|---|
| Fruit setting technology | ★★★★★ | Artificial pollination and selection of melon node locations |
| Variety recommendations | ★★★★☆ | 8424. Comparison between Meidu and Qilingua |
| Pest and disease control | ★★★☆☆ | Anthracnose and aphid control methods |
| Water and fertilizer management | ★★★☆☆ | Key points for top dressing during fruit setting period |
2. Analysis of key technologies for watermelon fruit setting
1. Pollination Management
The most discussed recently is artificial pollination technology. The best pollination time is between 7 and 10 am. Select strong male flowers and spread pollen evenly on the stigmas of female flowers. There have been frequent rainfalls in many places recently, so special attention needs to be paid to timely re-potting after rains.
2. Selection of melon section location
| Variety type | Ideal location for saving melons | Number of fruits per plant |
|---|---|---|
| Large fruit type | 15-20 knots | 1-2 pieces |
| Medium fruit type | 10-15 knots | 2-3 pieces |
| small fruit type | Section 8-12 | 3-4 pieces |
3. Environmental control
Recently, hot weather has occurred in many places. When planting in greenhouses, you need to pay attention to: keep the temperature at 25-30℃ during the day and 18-20℃ at night; control the air humidity at 50-70%; when the light is insufficient, you can appropriately supplement the light.
3. Answers to recent hot questions
Q: Why do watermelons bloom more but have less fruit?
A: According to recent discussions among agricultural technology experts, the main reasons include: ① Continuous rain during the flowering period; ② Excessive nitrogen fertilizer leads to leggy growth; ③ Reduction of pollinating insects; ④ Excessive remaining vines disperse nutrients.
Q: What is the recommended fertilizer program for the fruit setting period in the near future?
| fertilization period | Fertilizer type | Dosage (mu) |
|---|---|---|
| Early stage of fruit setting | High potassium water soluble fertilizer | 5-8kg |
| Fruit expansion stage | Calcium magnesium fertilizer | 3-5kg |
| 15 days before harvest | Stop topdressing | - |
4. Planting suggestions for the next 10 days
According to the weather forecast, the following conditions will occur in my country’s major watermelon-producing areas in the next 10 days:
| area | weather trends | Management points |
|---|---|---|
| East China | Many showers | Pay attention to drainage and waterlogging prevention, and replenish pollination after rain |
| North China | Sunny, hot and little rain | Strengthen irrigation to prevent sunburn |
| South China | High temperature and humidity | Improve ventilation and prevent diseases |
5. Latest suggestions from experts
Recently, experts from the Chinese Academy of Agricultural Sciences proposed: ① Promoting bumble bee pollination technology can increase the fruit setting rate by more than 15%; ② It is recommended to use amino acid foliar fertilizers to enhance stress resistance; ③ The 7 days after fruit setting is the critical period for preventing fruit cracking, and water balance needs to be maintained.
Through the above technical points and real-time data analysis, we hope to help growers solve the problem of watermelon fruit setting. It is recommended to continue to pay attention to weather changes and the latest planting techniques for better harvests.
