Recently, the problem of shriveled corn has become a hot topic in the agricultural field. This article combines the hot topics on the Internet in the past 10 days to sort out the causes and solutions of shriveled corn, and presents it in structured data to help growers respond quickly.
1. Common causes of shriveled corn
| Reason type | Specific performance | Proportion (discussion data of the entire network) |
|---|---|---|
| Not enough moisture | Dry soil and untimely irrigation | 35% |
| pests and diseases | Corn borer, rust, etc. | 28% |
| nutritional deficiencies | Potassium deficiency, nitrogen deficiency | 20% |
| climate anomaly | High temperature, strong light | 17% |
2. Comparison of popular solutions
| method | Applicable scenarios | Effectiveness score (1-5 points) |
|---|---|---|
| drip irrigation hydration | arid areas | 4.5 |
| Spray foliar fertilizer | nutritional deficiencies | 4.2 |
| Biological pesticide control | Initial stage of pests and diseases | 4.0 |
| Shade net coverage | High temperature and bright light | 3.8 |
3. Suggestions for staged treatment
1. Prevention phase:
• Choose drought-resistant varieties (such as "Zhengdan 958")
• Deeply plow the soil and apply sufficient base fertilizer before sowing
• Install soil moisture monitoring equipment
2. Middle growth stage:
• Check blade status weekly
• Check soil moisture content immediately if you notice signs of dryness
• Adopt the "little and often" irrigation principle
3. Remedial phase:
• Shrunken plants: Cut off the damaged parts and spray 0.3% potassium dihydrogen phosphate
• Severely diseased plants: remove them promptly to avoid spreading
• Consider using plant growth regulators when occurring over large areas
4. Summary of Expert Suggestions
| expert | institution | core ideas |
|---|---|---|
| Professor Zhang | Chinese Academy of Agricultural Sciences | 70% of dryness problems are caused by improper moisture management |
| Dr. Li | agricultural university | It is recommended to establish an early warning system for pests and diseases |
| Technician Wang | agricultural extension station | Promoting smart irrigation equipment can reduce incidence |
5. Latest research progress
1. The "Corn Drought Resistance and Water Retention Agent" developed by China Agricultural University has entered the field trial stage
2. A technology company launched an AI-based corn health monitoring system with an accuracy rate of 89%
3. New biostimulants can improve corn’s drought resistance by 30%
6. User FAQs
Q: Can corns recover after being shriveled?
A: Mild dryness can be restored by timely rehydration, while severe dryness needs to be pruned.
Q: When is the most effective time to water?
A: It is recommended to do it in the early morning or evening to avoid hot periods.
Q: How to judge whether it is water shortage or disease?
A: Water shortage is manifested by overall wilting, and the disease is usually accompanied by spots or deformities.
Through the above structured analysis and solutions, we hope to help growers effectively deal with the problem of corn dryness. It is recommended to choose the most suitable control plan based on local climate and soil conditions.
