How to increase greenhouse crop yields? Mainly from these aspects to start!

Selection of good varieties

Variety adaptability: Select crop varieties suitable for greenhouse environment, strong stress resistance and good disease resistance. These varieties generally show higher growth rates and yields under greenhouse conditions.

High yield potential: Preference is given to varieties with high yield potential to ensure that higher yields can be obtained under the same growing conditions.

Optimize planting structure

Reasonable arrangement of crop layout: according to the growth cycle and characteristics of crops, reasonable arrangement of crop layout in the greenhouse to avoid mutual interference and competition.

Crop rotation and intercropping: The use of crop rotation and intercropping to reduce the occurrence of pests and diseases, improve soil fertility, and achieve sustainable high yields.

Control environmental conditions

Light: According to the light needs of different crops, reasonable adjustment of the light intensity and light time in the greenhouse. For bright light crops, such as tomatoes, melons, etc., to ensure sufficient light; For low-light crops, such as lettuce, chrysanthemum chrysanthemum, etc., it is necessary to avoid too strong light.

Temperature and humidity: Through heating, cooling, ventilation and other measures to keep the temperature and humidity in the greenhouse in the most suitable range of crop growth. This helps boost photosynthesis and nutrient uptake in the crop, thereby increasing yields.

Ventilation: Regular ventilation to keep the air fresh in the greenhouse and reduce the occurrence of diseases and pests.

Rational fertilization management

Base fertilizer and topdressing: apply sufficient base fertilizer before planting, and topdressing in time according to the needs of crops during growth. Base fertilizer is mainly organic fertilizer, with appropriate amount of inorganic fertilizer; Topdressing is performed according to the growth stage and nutrient requirements of the crop.

Nutrient balance: Ensuring that crops receive a full supply of nutrients, including nitrogen, phosphorus, potassium, and trace elements. Through soil testing and plant nutrition monitoring, timely adjustment of fertilizer program to avoid nutrient excess or deficiency.

Pest prevention and control

Prevention: take physical control, biological control and chemical control and other means to prevent the occurrence of diseases and pests in advance.

Timely monitoring: Regularly check the growth of crops in the greenhouse, timely detection and treatment of pests and diseases

Comprehensive prevention and control: Combining various prevention and control measures to form a comprehensive prevention and control system to ensure healthy crop growth.

Rational irrigation management

Irrigation method: Use drip irrigation, sprinkler irrigation and other water-saving irrigation methods to reduce water evaporation and waste.

Irrigation time: According to the needs of crops and soil water conditions, reasonable arrangement of irrigation time and irrigation amount. Avoid irrigation during high temperature periods to avoid rapid evaporation of water and soil compaction.

Water quality management: Ensure that irrigation water quality is clean and pollution-free to avoid harm to crops.

Greenhouse management and maintenance

Regular cleaning: Keep the greenhouse clean and hygienic to reduce the breeding and spread of diseases and pests.

Facility maintenance: Regularly check the operation of greenhouse facilities, such as ventilation system, heating system, irrigation system, etc., to ensure their normal operation.

Record and analysis: record the environmental parameters and crop growth in the greenhouse, analyze and summarize regularly, and provide a reference for future production management.

To improve crop yield in greenhouse, we need to start from many aspects, including selection of excellent varieties, optimization of planting structure, control of environmental conditions, reasonable fertilization management, disease and pest control, reasonable irrigation management and greenhouse management and maintenance. Through the comprehensive application of these measures, the crop yield and quality of the greenhouse can be significantly improved.
