During the growing season, temperatures will rise significantly, and crops will enter their peak production period. At this time, field vegetables are more susceptible to pests, while greenhouse vegetables tend to experience premature aging. This is a crucial phase for vegetable growth, and it is essential to implement proper protective measures to ensure healthy development and high yields.
1. **Pest Control for Field Vegetables**
At this stage, the main principle of pest control should focus on prevention. Agricultural methods involve using disease-resistant varieties, seed disinfection, and proper field management to reduce pest and disease occurrence. These practices help suppress the spread of pathogens and lower infection rates.
Ecological control involves managing the environment to create unfavorable conditions for pests and diseases. Techniques such as improving air circulation, reducing humidity, and controlling temperature can effectively limit the spread of harmful organisms.
Biological control uses natural predators or bio-pesticides to manage pests in an environmentally friendly way. This method helps maintain ecological balance without harming beneficial insects or the environment.
Physical control includes using barriers, traps, or other physical means to prevent or repel pests. This can be especially effective in protecting young plants from damage.
Chemical control should only be used as a last resort, with low-toxicity and low-residue pesticides applied through foliar sprays or soil irrigation. The use of high-toxicity or long-residue chemicals is strictly prohibited to protect both the crops and the surrounding ecosystem.
2. **Greenhouse Vegetable Management**
As greenhouse vegetables reach the later stages of growth, careful management becomes even more important. It is crucial to prevent early aging by maintaining proper watering and fertilization. Ensuring that fruits and vegetables mature properly and harvesting them at the right time will help maximize yield and quality.
In cases where organic fertilizer is insufficient, additional nutrients must be provided promptly to avoid plant decline and maintain productivity. Proper care during this critical period ensures that the final harvest meets quality standards and remains profitable.
