When building greenhouses, in order to save time and effort, the mellow soil on the surface layer is generally used to build the shed walls, so that the soil used for planting vegetables is mostly raw soil about 1.5 meters from the surface, which lacks organic matter. Therefore, a large amount of organic fertilizer is needed.
1. Increase the application amount of manure such as chicken manure.
Newly built sheds are mostly raw soil and lack of organic matter. Therefore, a large amount of organic fertilizer should be supplemented. Organic fertilizers such as rice husk manure and chicken manure can increase the amount per mu to about 35 cubic meters. After the application of these organic fertilizers, the soil cannot be increased rapidly. In the organic matter, it can improve the physical and chemical properties of the soil to a certain extent.
2. Increase application of biological fertilizer.
In the newly built greenhouse, the content of various microorganisms in the soil is low. Even if a large amount of organic fertilizers such as chicken manure and rice husk manure are applied, the organic fertilizer cannot be quickly decomposed into soil organic matter due to the lack of microorganisms in the soil. Therefore, when vegetable farmers apply organic fertilizers such as rice husk manure and chicken manure to the newly built greenhouse soil, they must pay attention to increasing the application of biological bacterial fertilizer, such as applying 40 to 70 kg of biological bacterial fertilizer per acre to quickly replenish the microorganisms in the soil.
3. Increase the application of commercial organic fertilizers.
Commercial organic fertilizer has high organic matter content, which helps the soil quickly replenish organic matter after use. Vegetable farmers can apply manure to the soil of the new greenhouse for the first time, combined with the application of commercial organic fertilizer, and apply about 500 kg per mu, which can ensure the nutrients needed for the early stage of vegetable growth.
4. Supplement nitrogen, phosphorus and potassium fertilizers.
The soil in the new greenhouse is raw soil, and the content of nitrogen, phosphorus and potassium in the soil is extremely low, so when applying base fertilizer, you must pay attention to increasing the application of nitrogen, phosphorus, and potassium fertilizers. Generally, about 50 kg of chemical fertilizer is used per mu.
5. Supplement medium and trace elements.
For vegetables to grow healthily, they need not only nitrogen, phosphorus, potassium and other large elements, but also more than 10 medium and trace elements such as calcium, iron, and boron. The lack of medium and trace elements in the soil of newly-built greenhouses has become a prominent problem restricting the high yield and quality of vegetables.

what is Food safety and Quality services?
Food safety and Quality services is a broad field that covers a variety of professional activities and solutions to ensure the safety and quality of food from production, processing, storage, transportation to marketing. Here are some of the main services:
1. Regulatory Advisory and Compliance Services: Provide advice on national and international food safety regulations, standards and guidelines to help food companies understand and comply with relevant legal requirements.
2. Risk assessment and management: Identify and assess possible food safety risks in the food production chain, and develop and implement a risk management plan to reduce these risks.
3. Laboratory testing and analysis: Provide chemical, microbiological, physical and sensory testing and analysis services for food samples to ensure food quality and safety.
4. Supply chain monitoring and traceability: Through advanced technology and systems, real-time monitoring and traceability of the food supply chain to ensure traceability and transparency of the product source.
5. Education, training and capacity building: Provide food enterprises and related personnel with food safety and quality management training and education to improve their knowledge and skills.
6. Technical support and research and development: Provide technical support and research and development services for specific food or production process, including new product development, production process improvement and food safety technology research and development.
7. Crisis management and emergency response: In the event of a food safety incident, provide crisis management strategies and emergency response measures to protect public health and the reputation of the business.
8. Audit and third party audit: Conduct internal and external food safety and quality audits to verify that the enterprise complies with the specified standards and requirements.
The goal of Food Safety and Quality services is to protect the health of consumers, maintain public trust in the food industry, and help companies improve product quality, meet regulatory requirements and enhance market competitiveness. These services are usually provided by professional consulting companies, inspection agencies, scientific research institutions or relevant government departments.
