From normalcy to quality: Yuhuan Wendan Pomelo leverages biological vitality system to achieve both quality and profit improvement

summary:

Before the cooperation, the demonstration base, like most local orchards, faced problems such as incomplete water and fertilizer facilities, a single fertilizer structure, insufficient soil organic matter, low biological activity, and low nutrient utilization, which resulted in premature tree decline and difficulty in improving quality. By introducing the Klipsch bio-vitality system solution, the base has achieved comprehensive improvements from soil health, tree vigor restoration to fruit quality.

 

1. Background overview

Zhejiang Yuhuan Wendan pomelo is a national geographical indication product of China and has a cultivation history of more than 130 years. Its fruit has beautiful shape, rich aroma and unique flavor, and has high commodity value. In recent years, with government support and market promotion, the price of Wendan has stabilized, ranging from 4-8 yuan/jin depending on quality, and the planting benefits are significant. However, long-term reliance on traditional planting models and experience-based planting has led to problems such as soil degradation, weakened tree vigor, high fruit cracking rates, and unstable quality, which have restricted further development of the industry.

 

2. Industrial pain points and needs

Premature decline and death of trees: Due to problems such as freezing damage, excessive fruit bearing, Huanglongbing, soil ecological damage, and unreasonable use of fertilizers and chemicals, the trees have suffered serious decline.

High fruit cracking rate: It is difficult to control water in open-air planting and insufficient calcium supplementation, resulting in a decrease in commercial fruit rate.

Unstable quality: Factors such as low soil organic matter, nutritional imbalance, excessive fruit load, and improper use of conditioners affect sugar accumulation and flavor formation.

Growers’ core needs: Keep trees healthy, reduce fruit cracking, stabilize quality and improve economic benefits.

 

2. Core solutions and implementation points

In order to overcome the obstacles in Wendan cultivation, Boss Lin and Jiashi worked together to implement biodynamic cultivation technology at their base. This program covers many aspects such as soil conditioning, tree vigor restoration, crack prevention and quality improvement, and flavor improvement.:

l Soil ecological restoration: The application of "Tubeikang" + "root-enabled solid organic fertilizer" can effectively improve the soil aggregate structure, enhance the ability to retain water and fertilizer, and increase the organic matter content.

l Maintaining tree vigor and resisting stress and aging: “The use of "Dibei Kang" and "Norwegian Seaweed" can significantly enhance the stress resistance of Wendan trees, alleviate the problem of premature aging of the tree, and maintain the ability to produce steadily year after year.

l Fruit cracking prevention and quality basis: At the critical stage, special calcium source products such as "Biological Calcium" and "Calcium Bide" are used to supplement calcium elements to enhance the toughness of the peel and effectively reduce the fruit cracking rate. The commercial fruit rate reaches more than 90%.

l Flavor and Brix Control: Before ripening, use "Dian Qiuxiang" and "Root-nurturing water-soluble organic fertilizer" to promote the accumulation of sugar and the formation of aroma substances, and improve the taste.

l Weight loss enhancement and sustainable planting: The system solution significantly reduces the dependence on compound fertilizers and truly achieves the planting goal of “low investment, good quality, and high returns”.

three, Application results

Since the program was applied at Linbo’s base, it has achieved the following results in terms of output, quality, input-output, etc.:

 

The trees are strong and healthy, controlling the occurrence and spread of Huanglongbing

 

 

During the germination period, the buds begin to sprout. Using the live soil root awakening plan, the root system will sprout quickly, bud out earlier, the bud heads will be stronger, and the buds will sprout more neatly.

 

 

 

The peel of Wendan pomelo is more delicate, the oil cells are denser, and the quality is higher.

years	Number of fruits (10,000 pieces)	Estimated output (10,000 kilograms)	Selling price (yuan/jin)	Description of key influencing factors
2021	2.8	10	7-8	In the initial stage of application, basic output.
2022	3.2	12	7-8	The plan continues to be optimized and the tree vigor is gradually restored.
2023	5.0	18	8-12	The system solution is effective, and the health and stress resistance of the tree are significantly improved.
2024	3.0	12	13-16	Affected by the felling of trees after regional freeze damage and the low number of flowers caused by the climate, the quality premium is obvious.

Annual dosage of compound fertilizer per mu	100 - 200 pounds	&<20 pounds	Reduce more than 80%
Product fruit rate	High fruit cracking rate	More than 90%	significant improvement
Mu input cost	About 1500 yuan	About 3500 yuan	An increase of approximately 133%
Sales unit price of land	base price	Basic price + 3~5 yuan/catties	The premium is obvious
soil health	Hardening, acidification, low organic matter	Loose, breathable, and organic matter is significantly improved	fundamental improvement
Customer repurchase and positive reviews	unstable	100% return rate and 100% positive review rate	Quality customer acquisition effect is remarkable

4. Improvements in quality and tree vigor are highly recognized

Through the implementation of the system solution, the demonstration base Wendanyou has outstanding performance in quality: The fruit has fine pulp, juicy flavor, strong pomelo aroma, refreshing taste, sweet but not greasy taste. Compared with conventional orchards, the fruit is disease-free and has obvious flavor advantages. The strong tree vigor has also effectively resisted the intrusion of frost damage and Huanglongbing, and the number of dead trees has been significantly reduced. This solution not only significantly improved fruit quality and planting efficiency, but also gradually accumulated its own retail customer base through quality premiums, successfully transformed into a high-quality and low-price sales model, and the benefits far exceeded those of conventional wholesale channels.

Boss Lin said: “Jieshi’s concepts and technical services are very good and consistent with the organic and green planting concepts that I aspire to and practice. The biggest help to me is to condition the soil, make the trees stronger, increase the yield, the quality and taste are completely different, and I have more confidence in selling. ”

5. Summary and Outlook

To sum up, the biological vitality system solution systematically solves the difficulties and pain points in traditional planting through soil conditioning, tree vigor maintenance and quality control. It not only reduces the investment in chemical fertilizers, but also achieves a significant improvement in the quality, selling price and economic benefits of Wendan. This plan takes into account both eco-friendliness and economic benefits, providing a reliable path for the sustainable development of Wendan industry.

In the future, we will continue to optimize the system solution, further promote the application of this model in Yuhuan and even more Wendan planting areas, and help more growers realize their desire to "grow good Wendan and sell it at a good price."
