In another year of citrus harvest, the orchards in Xinglong Village, Baima Town, Dongpo District, are once again filled with the golden glow of ripe oranges. One mid-September afternoon, a reporter visited the local citrus grove and observed an innovative pest control method in action—black lights were hung among the trees to attract harmful insects. Alongside, predatory mites were introduced to feed on red spider mites, while natural predators helped maintain the balance of the ecosystem. The oranges, plump and vibrant, stood as a testament to the success of these sustainable practices.
Peng Xiquan, the orchard owner, shared his satisfaction with the results. Since his family adopted a new approach using wolfberry-based prevention methods, they've significantly reduced pesticide use while improving fruit quality. His family manages 11 acres of orange trees, producing around 3,500 kilograms per mu. At a wholesale price of 2 yuan per kilogram, their citrus is expected to generate over 70,000 yuan this season—a promising sign for their business.
According to Peng, citrus has long been a vital part of the rural economy in Dongpo District. However, spider mites have always been a major threat. Traditionally, farmers relied heavily on chemical pesticides to combat them, but this practice has led to increased resistance, higher pesticide concentrations, and severe residue issues. These problems not only affect fruit quality but also hinder exports, making it hard to sell at competitive prices.
The overuse of pesticides has also caused environmental pollution, harming beneficial insects and disrupting the natural balance. As a result, citrus production struggles to meet the standards of pollution-free farming, limiting its long-term growth. To address this, the Dongpo District Agriculture Bureau introduced biological control methods by introducing natural enemies of red spider mites, such as predatory mites that target pests like rust mites and other harmful species. This approach effectively controls pest populations, reduces the black fruit rate, and minimizes the need for chemical sprays.
The benefits of this method are clear: no pesticide residues, no environmental damage, and safe, eco-friendly farming. It’s also easy to implement and requires less labor, making it a practical solution for farmers. Beyond citrus, this technique can be applied to control various small pests in flowers, greenhouse vegetables, edible fungi, and even garden plants.
With this shift toward sustainable agriculture, farmers like Peng are not only protecting their crops but also ensuring a healthier future for both their land and consumers.
Passive Lock
Passive locks are essential security components designed to provide reliable, low-maintenance locking solutions for a wide range of applications. Unlike active locking systems that require electronic control or user interaction to engage, passive locks function through mechanical means, automatically securing doors, cabinets, drawers, or enclosures once closed. They are widely used in residential, commercial, and industrial settings where simplicity, durability, and cost-effectiveness are priorities.
These locks come in various forms such as cam locks, latch locks, cabinet locks, deadbolts, and strike plates. They typically operate by engaging a catch or bolt when the door or drawer is pushed or closed, preventing unauthorized access without requiring keys or combinations to activate the locking mechanism each time. Passive locks are especially valued for their ability to maintain security without ongoing power supply or complex electronic components, making them ideal for environments where reliability and ease of use are crucial.
Common applications of passive locks include furniture cabinets, tool chests, lockers, storage units, and display cases. They are also frequently found in industrial equipment enclosures, electrical panels, and automotive compartments. Many passive locks are constructed from robust materials such as steel, brass, or zinc alloy, ensuring resistance to tampering, corrosion, and everyday wear.
In addition to mechanical durability, passive locks often feature design elements that enhance user convenience, including smooth operation, compact size, and compatibility with various door and drawer thicknesses. Some models integrate childproof features or tamper-resistant mechanisms to provide additional safety in sensitive environments like homes, schools, and healthcare facilities.
Overall, passive locks offer a dependable and straightforward locking solution where continuous security is needed without the complexity of active locking systems. They balance security, functionality, and affordability, making them a popular choice across multiple industries and applications.
