Shandong Destroys "Poisonous Scallions"! Want to Eat Peace of Mind Vegetables
When the Shandong poisonous scallion incident caused food safety concerns, where should urban residents place the safety of their vegetable baskets?

Guide to Growing Vegetables on Balcony
Complete Process of Growing Scallions
Choose a long rectangular pot with a depth of over 20cm, mix humus soil with perlite (3:1). Plant 3 seeds per hole with a 5cm interval and cover with 0.5cm of soil. Use the immersion pot method to water and keep the matrix moist, and you can see the seedlings break through the soil in 7-10 days. It is recommended to plant in batches to ensure continuity (G-Y).
Tips for Planting Eggplant and Pepper
Tomatoes should be soaked in warm water at 55°C for disinfection before planting, and covered with film to maintain a constant temperature of 28°C after planting. Peppers need to choose second-generation hybrid seeds and soak in gibberellin solution before planting to improve germination rate. Eggplant seedlings need to be rotated weekly to ensure even lighting and use a drip irrigation system to accurately control humidity.
Space Management for Vine Plants
It is recommended to use a three-dimensional planting frame for planting green beans, combined with an automatic tendril guidance system. When the main vine reaches 30cm, pinch the tip to promote branching, and apply phosphorus and potassium fertilizer during the flowering period. The innovative use of hanging planting method allows the vines to form a natural sunshade curtain, considering both function and aesthetics.

Smart Vegetable Growing System Configuration
Modern balcony vegetable growing can be equipped with an environmental monitor to detect soil EC value, PH value, and light intensity in real-time. It is recommended to use a compost bin to convert kitchen waste into organic fertilizer, combined with a solar-powered automatic irrigation device to build a closed-loop ecological planting system.
Full Cycle Management from Planting to Consumption
Establish a planting calendar to record the growth cycle of each variety, and use biological control instead of pesticides. After harvest, use vacuum cold storage technology to extend the shelf life, and use nutrient content testing to verify the advantages of home-grown vegetables.
When food safety becomes a national issue, growing vegetables on balconies has evolved beyond simple farming, becoming a survival wisdom for urban people. Through standardized planting processes, intelligent equipment assistance, and a systematic knowledge framework, every family can create their own peace of mind vegetable garden. This is not only a change in the way food is obtained but also a redefinition of a healthy lifestyle by modern people.
