The use of cold sheds for growing hard-tomato spring and summer pods offers numerous benefits, including effective crop protection, low-cost infrastructure, quick results, and ease of management. Below are the key management practices before and after planting. 1. **Preparation for Planting**: The process begins in mid-March, about 20 days before planting. First, the temperature inside the cold shed should be raised to eliminate any pests or pathogens. Insect-proof nets should be installed on vents and entrances. As soon as the ground thaws, plowing is done, followed by the application of 50,000 kg of organic manure per acre and 80 kg of 15:15:15 NPK fertilizer as a base. The soil is then deeply turned to a depth of 30 cm, broken up, and leveled to create a firm bed. 2. **Plant Spacing**: The recommended spacing between plants is 40 to 45 cm, with rows spaced 75 to 80 cm apart. This allows for approximately 1,700 to 1,900 seedlings per mu. It’s best to plant on high ridges to improve drainage and air circulation. 3. **Seedling Care**: One of the most important aspects of seedling management is maintaining proper temperature. During the day, the temperature should be kept between 25°C and 30°C, while at night it should remain between 15°C and 18°C. In the early growth stage, the greenhouse environment is more enclosed, so it's crucial to monitor for any harmful gases that may develop from the organic fertilizers. If necessary, ventilation should be done promptly. 4. **Slow Growth to Fruit Setting**: During this phase, the daytime temperature should be maintained at 23°C to 25°C, and the vents should be closed when the temperature drops to 18°C to 20°C in the afternoon. Nighttime temperatures should stay between 13°C and 15°C. Watering and fertilization are critical during this time. After planting, water the seedlings every 5 to 7 days. On sunny mornings, choose to water, and apply 10 kg of urea along with the irrigation. Once the soil becomes workable, loosen the top layer to promote root development. 5. **Post-Fruit Set Management**: Once the plants start fruiting, it’s important to ventilate the shed regularly. Start ventilation when the temperature inside rises to 25°C. Keep the internal temperature between 23°C and 25°C during the day, around 20°C in the afternoon, and 15°C to 18°C at night. Maintain humidity levels between 50% and 60% to reduce disease risk. When the first ear reaches about 4 cm in diameter, water again and apply 25 to 30 kg of 15:15:15 NPK fertilizer per acre. From April, water every 8 days, and from May onwards, water every 6 days. Each time you water, apply an additional 25 to 30 kg of 15:15:15 compound fertilizer to support fruit development. Consistent care during these stages ensures healthy growth and higher yields.

Food Additives

Detailed introduction of food additives

Food additives are chemical substances that are added during food production and processing to improve the quality and characteristics of food. They can improve the taste, color, texture, freshness, and nutritional value of food products and provide consumers with a better food experience.

First, let's introduce a common food additive, food coloring.

Food coloring is mainly used to change the color of food to make it more attractive. Common food colorings include natural colorings and synthetic colorings. Natural pigments generally come from plants, animals or microorganisms, such as carotene and chlorophyll. Synthetic pigments, on the other hand, are obtained through chemical synthesis, such as bright blue pigment and lemon yellow pigment. Food coloring is widely used in food products such as pastries, beverages, jams, etc. to make them more colorful and diverse.

Secondly, food preservatives are also one of the common food additives.

Food preservatives can prolong the freshness period of food and reduce the growth of bacteria and molds, thus maintaining the freshness and quality of food. Common food preservatives include sulfates and nitrites. They are widely used in meat products, fruit and vegetable products, canned food, etc. to ensure that the food is not easy to rot and deteriorate.

Besides colors and preservatives, food thickeners are also one of the commonly used food additives.

Food thickeners can increase the consistency and texture of food, making it taste better. Common food thickeners include gelatin and pectin. They are widely used in jellies, sauces, dairy products and other foods to enhance the taste and quality of food.

In addition, food sweeteners are also one of the common food additives.

Food sweeteners can replace traditional sugars to provide sweetness to food while reducing calorie intake. Common food sweeteners include sucralose and aspartame. They are widely used in candies, beverages, chewing gums and other foods to satisfy people's need for sweetness.

Finally, let's introduce a common food acidifier - citric acid.

Citric acid can increase the sour flavor of food and enhance the taste of food. It is widely used in beverages, jams, condiments and other foods to make them more refreshing and delicious.

The food additives we provide to our customers play an important role in food production and processing. They can improve the taste, color, texture and freshness of food, and enhance the quality and nutritional value of food.
