Aiming at the problems of excessive branch growth, disordered fruiting and low commercial fruit rate of greenhouse tomatoes, this paper expounds scientific pruning and fruit thinning technologies to optimize nutrient distribution and realize quality and yield improvement.

Aiming at the core problems prevalent in the whole process of tomato planting, such as universal management mistakes, growth disorder, frequent physiological diseases, difficult yield increase and quality improvement, this paper systematically sorts out high-frequency wrong operations in all links of seedling cultivation, transplanting, field management, water and fertilizer application, pruning and fruit thinning, harvesting and storage and transportation, accurately diagnoses the causes of various abnormal symptoms, and supports standardized correction schemes and preventive measures. It thoroughly solves the pain points of difficult stable yield and high quality in tomato planting, and improves the complete set of standardized tomato cultivation technology system.

Aiming at the problems of blind fertilization, unbalanced nitrogen, phosphorus and potassium, lack of medium and trace elements, early excessive growth and late premature aging in tomato planting, this paper formulates standardized base fertilizer formulas, staged topdressing schemes and foliar nutrient supplementation technologies according to the fertilizer demand rules of tomatoes in each growth stage, realizing balanced nutrition, stable yield and quality improvement, cost saving and efficiency enhancement.

Aiming at the problems of single planting mode, disordered stubble arrangement, long empty greenhouse period, low facility utilization rate and aggravated continuous cropping obstacles in greenhouse tomato production, this paper optimizes the mainstream annual stubble modes suitable for northern greenhouse tomatoes, and supports whole greenhouse disinfection, empty greenhouse restoration, stubble connection and whole-process unified management technologies, so as to maximize facility utilization rate and realize annual stable and efficient production.
