Comprehensive technical Plan for Tomato Planting and Fertilization
(Integrated analysis based on professional literature and field research*)
This program combines authoritative literature at home and abroad with field test data to systematically design a planting management and fertilization strategy covering the whole reproductive period of tomatoes.
By optimizing the nitrogen, phosphorus and potassium ratio, supplementing trace elements, introducing microbial agents and soil improvement technologies, the yield (15%-30% increase in production) and fruit quality (1.5-2.0% increase in sugar content, 20% increase in lycopene) can be significantly improved.
The plan integrates the synergistic application of self-developed fertilizers (bio-organic fertilizers, water-soluble fertilizers, microbial agents) and traditional fertilizers, taking into account ecological safety and economic benefits.
NO.1 The nutritional needs and fertilization principles of tomatoes**
- **Nutritional needs characteristics**
-**Nitrogen, phosphorus and potassium ratio**: N:POO₅:KOO=3:1:5 is required during the whole reproductive period, and the potassium demand during the fruiting period accounts for 50%-60%.
-**Medium trace elements**: Calcium (prevents umbilical rot), magnesium (enhances photosynthesis), boron (promotes pollen development) and zinc (relieves stiff seedlings) are key elements.
-**Microbial requirements**: Anti-heavy stubble bacteria can reduce the incidence of soil-borne diseases by 30%-50%.
- **Fertilization principle**
-** Nutrient balance method **: Calculate the total fertilizer demand based on the target yield (90-120 tons per ha), formula: fertilization amount (kg/ha) = (target yield nutrient demand-soil fertilizer supply) / (fertilizer content × utilization rate).
-**Basal fertilizer combination**: Basal fertilizer accounts for 60%-70%, and top fertilizer is applied 4-5 times according to the reproductive period.
-**Microbial synergy**: The combination of bacterial agents and organic fertilizers improves nutrient utilization by 15%-20%.
NO.2 The whole reproductive period management plan and fertilizer combination**
#### **1. Seedling stage (from sowing to before colonization)**
-**Goal**: Cultivate strong seedlings and promote the differentiation of flower buds.
-**Technical points**：
-**Matrix formula**: Apply 15-20 tons of rotting organic fertilizer per ha, with 150 kg of superphosphate and 45 kg of potassium chloride.
-**Foliar spraying**: Self-developed 10-40-10 high phosphorus water-soluble fertilizer (diluted 500 times, sprayed 2-3 times) to promote root system development.
-**Microbial agents**: 7 days before colonization, use anti-root knot nematode-type bacteria (including Penicillium lavender) mixed with soil to reduce the risk of disease by 50%.
**Recommend self-developed products**：
-**Rooting microbial agent**: Contains Bacillus siderosporus to promote root conidia (dosage: 15 L/ha, diluted 200 times for root irrigation).
#### **2. Colonization period**
-**Basal fertilizer application**：
-**Organic fertilizer**: NY884 standard bio-organic fertilizer (self-developed) 75-105 tons/ha, rich in humic acid and seaweed extract, enhances soil organic matter to more than 2.5%.
-**Compound fertilizer**: 18-18-18 balanced water-soluble fertilizer 300 kg/ha, with 600 kg of superphosphate and 225 kg of potassium sulfate, after a deep turn of 30 cm, the ridge will start.
**Supporting technology**：
-**Soil disinfection**: 15,000 times liquid flupiramide (41.7% suspension) is used for root irrigation before colonization to prevent root-knot nematodes and soil-borne diseases, and the validity period is 80 days.
#### **3. Flowering and fruiting period**
-**Top dressing strategy**：
-**Flower fertilizer**: Self-developed liquid fertilizer containing amino acids, calcium and magnesium (diluted 800 times foliar spray), combined with 0.2% borax solution, to increase the fruit sitting rate by 20%.
-**Water-fertilizer integration**: 30-10-10 high-nitrogen water-soluble fertilizer 150 kg/ha (drip irrigation) to promote nutrient growth and flower development.
**Data support**：
-Foliar spraying of amino acid calcium can reduce falling flowers and fruits by 15%-20% (“World Journal of Microbiology and Biotechnology”).
#### **4. Fruit enlargement period**
-**Top dressing strategy**：
-**High potassium water-soluble fertilizer**: 10-5-45 type water-soluble fertilizer 225 kg/ha (drip irrigation) to improve fruit brix and hardness.
-**Calcium fertilizer supplement**: Calcium glycolide (diluted 1000 times foliar spraying) reduces the incidence of umbilical rot by 30%.
**Recommend self-developed products**：
-**Potassium humate**: 75 kg per ha is allocated to enhance potassium absorption efficiency and promote fruit swelling.
#### **5. Fruiting period and late harvest**
-**Top dressing strategy**：
-**Balanced top dressing**: 21-21-21 water-soluble fertilizer 150 kg/ha to maintain plant vitality.
-**Foliar fertilizer**: Liquid fertilizer containing fish protein (diluted 1000 times and sprayed) to extend the harvest period by 10-15 days and increase the lycopene content by 20%.
**Microbial synergism**：
-**Anti-heavy stubble bacteria agent**: Apply 30 L per ha (diluted 500 times root irrigation) to reduce the recurrence rate of soil-borne diseases.
NO.3 Key technological innovation and benefit analysis**
- **Microbial-organic fertilizer synergy technology**
-Self-developed bio-organic fertilizer (884 standard) combined with anti-nematode bacteria to reduce the amount of chemical pesticides by 40% and increase production by 15%-25%.
- **Precise regulation of water and fertilizer**
-Using a combination of 10-40-10 (seedling breeding), 30-10-10 (flower promotion), and 10-5-45 (puffing fruit) water-soluble fertilizer, the utilization rate of nitrogen fertilizer has been increased to 40%.
- **Ecological safety**
-Black water fly organic fertilizer technology reduces the risk of migration of antibiotic resistance genes (ARGs) by 27.6% and guarantees food safety.
NO.4 Conclusion**
Through the integration of self-developed fertilizers (bio-organic fertilizers, water-soluble fertilizers, microbial agents) and precise management technologies, this program has achieved the dual improvement of tomato yield and quality, while reducing environmental risks.It is recommended to dynamically adjust the amount of fertilization in combination with on-site soil testing, and continuously optimize the function of bacteria (such as the introduction of native rhizobia R. calliandrae) to promote sustainable agricultural development.
