What to do with taco cores: Analysis of recent hot topics and solutions
Recently, the issue of "taco cores" has become a hot topic in the agricultural field, with many farmers and agricultural experts discussing this phenomenon on social media and forums. This article will combine the hot content of the entire Internet in the past 10 days to analyze the causes, impacts and solutions of taco heart, and provide structured data for reference.
1. Overview of the taco heart phenomenon
Corn core refers to the curling and deformation of corn leaves during the growth process, which seriously affects photosynthesis and yield. According to recent monitoring data from the agricultural department, this problem has occurred in many major corn-producing areas.
| area | Affected area (10,000 acres) | Main symptoms |
|---|---|---|
| North China | 120 | Leaves curled and yellowed |
| Northeastern region | 85 | Distorted heart leaves and retarded growth |
| Central China | 65 | Leaves curled, leaf margins scorched |
2. The main reasons for taco heart
According to feedback from agricultural experts and farmers, the main causes of corn core include the following aspects:
1.climatic factors: The recent high temperature and drought weather in many places has caused the water in corn leaves to evaporate too quickly, causing curling.
2.pests and diseases: Infestation by pests such as thrips and aphids is another major cause of corn cores.
3.nutritional imbalance: The lack of certain trace elements in the soil, such as calcium, magnesium, etc., will affect the normal growth of corn.
4.Herbicide damage: Some farmers have reported that improper use of herbicides may lead to corn cores.
| Reason type | Proportion | Typical symptoms |
|---|---|---|
| climatic factors | 45% | overall curl |
| pests and diseases | 30% | Partial curling and worm spots |
| nutritional imbalance | 15% | With yellowing |
| Herbicide damage | 10% | Deformity of new leaves |
3. Solutions and preventive measures
For different reasons, agricultural experts have proposed corresponding solutions:
1.Coping with high temperatures and droughts: Timely irrigation, drip irrigation or sprinkler irrigation can be used; spray foliar fertilizer during high temperature periods to enhance stress resistance.
2.Control pests and diseases: Use pesticides such as imidacloprid and thiamethoxam to control thrips; pay attention to rotation of pesticides to avoid drug resistance.
3.Supplement nutrients: Through soil testing, targeted supplementation of calcium, magnesium and other trace elements; foliar fertilizer containing amino acids can be sprayed.
4.Avoid drug harm: Use herbicides in strict accordance with the instructions; avoid applying herbicides during high temperature periods; spray antidote promptly when damage occurs.
| Question type | Recommended actions | Effect evaluation |
|---|---|---|
| climatic wrap | Timely irrigation + foliar fertilizer | Effective within 3-5 days |
| insect pest | Pesticide treatment | Control within 7 days |
| Nutritional rolls | Soil improvement + foliar fertilizer | Improvement in 10-15 days |
| drug-induced tangle | Antidote + growth regulator | Depends on severity |
4. Farmers’ experience sharing
In recent online discussions, many experienced farmers shared their coping methods:
1. Mr. Wang, a farmer from Shandong: "After discovering the corn core, I immediately sprayed foliar fertilizer containing alginic acid and watered it in the morning and evening. It improved significantly after 3 days."
2. Ms. Li, a farmer in Henan: "Thrips are particularly serious this year. I used a combination of imidacloprid + bifenthrin. The effect is very good, but I have to pay attention to the safety interval."
3. Agricultural expert Professor Zhang: "Prevention is better than cure. It is recommended to test the soil before sowing, apply balanced fertilization, and choose varieties with strong stress resistance."
5. Future prevention suggestions
1. Choose corn varieties with strong stress resistance, such as Xianyu 335, Zhengdan 958, etc.
2. Establish a monitoring and early warning system for pests and diseases to prevent in advance.
3. Promote water-saving irrigation technology to cope with extreme weather.
4. Strengthen technical training for farmers and improve scientific planting levels.
Although the taco core problem has become more prominent recently, it can be effectively controlled and solved through scientific analysis and reasonable countermeasures. It is recommended that farmers take targeted measures based on actual conditions to ensure normal growth of corn and ensure yields.
