Biodynamic cultivation method + digital technology solves the bottleneck of lychee soil degradation and achieves high quality and stable yield - taking "Fengshan Red Lantern" as an example

1. Industrial Challenges: Soil degradation restricts development of high-quality litchi

“ Fengshan red lantern ” As a famous variety in eastern Guangdong, lychee is popular in the market for its unique quality and high yield. However, long-term farming and improper management have resulted in serious challenges for the soil in core production areas.:

l Severe soil acidification: Tests show that soil pH is generally at an extremely low level of 4.8-5.46.

l Lack of organic matter: Organic matter content as low as 15.51g/kg ( The ideal range is 30-60g/kg ) , there is a serious lack of effective calcium and magnesium, and the problem of nutritional imbalance is prominent.

l High risk of quality fluctuations: The above problems lead to unstable fruit quality, “ frog skin ” , “ Reduce sugar ” The phenomenon occurs frequently, seriously affecting the sales window period and price stability, and restricting the development of industrial scale.

l Management lacks precision: Water and fertilizer management that relies on traditional experience lacks data support, making it difficult to implement precise policies and replicate and promote plans.

These problems have led to large fluctuations in the economic benefits of growers, making it difficult to fully realize the potential of high-quality lychee varieties.

 

2. Innovative solutions: Biological vitality cultivation method + digital precision management

Targeting the core pain points, Jiashi Agricultural Science and Shantou Bioactive Cultivation Method Star Demonstration Base Integrated a set biology+ and Digitization Systematic solutions for , Demonstrated remarkable results in practice:

1 , Soil ecological restoration foundation

l Apply more organic: Continuous application “ Roots can nourish ” Solid organic fertilizer and biocalcium increase soil organic matter content.

l Live soil to nourish roots: Root irrigation is rich in organic matter of “ black gold green ” and Soil microbial activator for microbial metabolites “ tubeikang ” , effectively improve the soil structure and promote root health (actual observations show that the soil becomes loose, earthworms reappear, and the ecology for the better).

l Reduce application and increase efficiency: By activating soil nutrients and promoting release and absorption, it improves soil fertility while reducing dependence on chemical fertilizers.

2 , Five key cultivation technology systems

l Nurturing trees to strengthen their branches: Optimize base fertilizer combination Roots can nourish Organic fertilizer + biological calcium + Root irrigation with Wujin Green + Tubeikang can quickly restore tree vigor and lay the foundation for a high yield.

l Vitality promotes flowers: During the critical period, apply flowering fertilizer on the leaves with Megafoul/Norwegian Seaweed + Aiwang to promote strong germination and uniformity of flower buds.

l Immune fruit protection: The leaves are sprayed with Norwegian seaweed + fruit moisturizing, which resists stress and stabilizes the fruit, effectively increases the fruit setting rate, and promotes the rapid greening and enlargement of the small fruits.

l Nutritious fruit: Ye spray Bicomei +Calcium Bide/Protein Potassium improves photosynthetic efficiency ； Root application of Black Gold Green promotes root absorption of fertilizers, relieves high temperature inhibition, and effectively promotes fruit enlargement and sugar accumulation.

l Natural color and sugar enhancement: The leaves are sprayed with Mejiafu + protective potassium, and the roots are sprayed with Futawang + potassium sulfate to promote the conversion and accumulation of sugar, making the color red and natural, and effectively delaying the withdrawal of sugar.

3 , Digital empowerment for precise management

l Real-time monitoring: Deploy soil moisture, temperature, and EC (electrical conductivity) sensors to achieve dynamic monitoring of key indicators.

l Precision irrigation: Based on data guidance, ensure that the soil moisture in key phenological periods (such as the physiological fruit drop period) is stable in the optimal range (about 50%), effectively reducing fruit drop.

l Precise fertilization: According to the EC value change (such as setting the threshold 0.2 Start fertilizing when )science guide The timing and dosage of fertilization can achieve efficient utilization of water and fertilizer (practical cases show that the number of fertilization applications during the fruit period in 2024 is reduced from 4 to 2 times, and the dosage is halved).

 

3. Empirical results: Data demonstrates the value of technology

After three years of technology integration and application, Shanwei Bioactive Cultivation Method Star Demonstration Base and Service Orchard have made breakthrough progress:

1. Soil health significantly improved

Table 1 Changes in soil testing data

years	Organic matter g/kg	pH	Effective calcium mg/kg	Effective magnesium mg/kg	Alkaline hydrolyzed nitrogen mg/kg	Available phosphorus mg/kg	Available potassium mg/kg	EC
2020.11	15.51	5.46	81.25	62.93	34.93	58.81	112.18	0.06
2023.07	27.93	5.84	1138.45	375.27	64.61	809.06	111.19	0.08
2024.01	12.53	6.11	1213.95	154.84	60.57	310.07	131.20	0.33

 

l pH value increased from 5.46 to 6.11 ( January 2024 ) , effectively relieve acidification.

l The effective calcium content is increased by more than 10 times (81.25mg/kg → 1213.95mg/kg), and the effective magnesium content is significantly increased. ( 62.93mg/kg → 154.84mg/kg ) , meets and far exceeds normal standards.

l The physical structure of the soil is improved (loose), and the ecological functions are restored (earthworms reappear).

 

2. Steady improvement in output and quality

Table 2 Changes in output and quality of application bases in four years

years	Total output (jin)	Average plant yield (jin)	average sugar content	Average sales price (yuan/jin)	input-output ratio
2021	20000	≈130	19.0	35	1:4
2022	25000	≈163	18.9	42	1:6
2023	34000	>200	20.7	40-60	1 : 10
2024	14000	≈90	20.0	45-65	1:6.3

Remark: In 2024, Guangdong litchi faced a historic flowering challenge (general flowering rate was <10%). The flowering rate of the base remained at 40-50%, and after experiencing strong convective weather during the small fruit period, it still maintained significantly better yields and profits than surrounding areas.

 

Core benefit highlights ：

l Significantly stable production and resistance to stress: In 2023, the maximum yield per plant set a record of 480 kilograms. Against the background of extreme production cuts in the industry in 2024, the base has demonstrated significantly stronger ability to resist risks.

l Steady improvement in quality: The sugar content increases steadily and remains at around 20 degrees, effectively delaying sugar withdrawal and ensuring fruit quality and market competitiveness in the mid-to-late period.

l Significant cost savings and efficiency gains: With biological vitality technology as the core, chemical fertilizer inputs are significantly reduced (in practical cases 2024 fruiting period Fertilizer usage is halved). In 2023, output will increase by 36% year-on-year, input will only increase slightly by 7%, and the input-output ratio will be as high as 1:10. Even in the grim year of 2024, the input-output ratio remains at an excellent level of 1:6.3.

l Technology is highly replicable: Combined with digital management, an accurate, quantifiable, and replicable implementation plan can be formed to provide strong support for the large-scale promotion of technical services.
