No input sales. No referral fees. Ever. 不卖投入品，不收推荐费。
We take no revenue from inputs. No product sales, no commissions, no kickbacks. This structural independence is the foundation of everything we say.
我们不从投入品上赚一分钱——不卖产品，不收推荐费——这正是我们能对种植者说实话的原因。
Independent Crop Diagnostics
We sell diagnosis,
not inputs.
我们只做诊断，不卖投入品。
An independent diagnostics company for South China agriculture. We measure what a crop has actually taken up — in sap and in soil — verify it against a third-party lab, and publish the results. 素固是一家面向华南农业的独立诊断公司。我们检测作物真正吸收到的养分，经第三方实验室核验后公开结果。

A recommendation is only as good as the data under it. 一项建议是否可信，取决于它背后的数据。
Most agronomy advice comes from whoever is also selling the fertilizer. That conflict is so normal in the industry it has stopped being visible. SoKu removes it structurally: we sell no inputs and take no referral fees, so nothing in our advice is shaped by something we are trying to move.
给农户建议的人，往往也在卖肥料。这种利益冲突在行业里太普遍，普遍到没人再当回事。素固从结构上把它去掉：不卖投入品、不收推荐费——所以我们的每一条建议，都不会被"想卖什么"左右。
"Verifiable honesty is the differentiator."
可被核验的诚实，才是真正的区别。
Every figure we report is tied to a physical sample and cross-checked against an accredited third-party lab. We publish all of it — including the trials that failed and the calls we got wrong.
我们报告的每一个数字，都对应一份实物样本，并经第三方权威实验室交叉核验。结果全部公开——包括失败的试验和我们判断错的地方。
The rules that keep the diagnosis honest. 独立原则：让诊断保持诚实的规则。
Every result published — the failures included. 每一项结果都公开，包括失败的。
We publish all results, including trials that failed and judgments we got wrong. In a field built on selling certainty, verifiable honesty is the differentiator.
我们公开所有结果——包括失败的试验和判断错误的地方。在一个靠"卖确定性"的行业里，可被核验的诚实才是真正的区别。
Field readings + independent lab. Both published. 现场数据自测，实验室独立核验，两者都公开。
Field readings are ours; the lab panel is not. Both are published and cross-referenced. Speed from the field, accuracy from the lab — each checks the other.
现场检测由我们完成，实验室分析由第三方完成。两者都公开并交叉比对。现场提供速度，实验室提供精度，互相验证。
Sap and soil, measured and verified. 汁液与土壤，实测并核验。
Differential sap analysis 差异化汁液分析
Young and mature tissue are sampled and measured separately. The difference shows where nutrients are moving and where deficiency is forming — weeks before it shows, and where soil tests alone would miss it.
分别采样并测量幼嫩组织和成熟组织。两者差异显示养分流动方向和缺乏形成位置——比症状出现早数周，也是土壤检测无法捕捉的信息。
Field meters, then ICP-OES 现场检测 + 实验室
Potassium, nitrate, calcium and pH are read on site with ion-selective electrodes. Samples then go to a third-party lab for full-spectrum ICP-OES analysis. The field gives speed; the lab gives accuracy.
钾、硝酸盐、钙和pH值由现场离子选择电极读取。样本随后送往第三方实验室进行全谱ICP-OES分析。现场提供速度，实验室提供精度，互相验证。
Recalibrated for South China 为南方作物校准
Almost every published sap reference range comes from temperate crops. Subtropical species, acidic red soils, and CAM plants like dragon fruit need their own protocols and reference ranges. Building those is the work.
几乎所有已发表的汁液参考范围都来自温带作物。亚热带物种、酸性红壤、以及火龙果等CAM植物需要自己的采样协议和参考范围。建立这些正是我们的工作。
The advantage is not the data. It is being trusted with it. 真正的优势不是数据，而是被托付。
Baseline data visualization coming Autumn 2026基线数据可视化将于 2026 年秋季公布
An open dataset gets absorbed — by an AI, by a competitor — the same way interpretation does. Neither stays scarce. What does not get absorbed is the position: an independent diagnostician South China has learned to trust, with no reason to sell it anything.
公开的数据会被吸收——被 AI，被同行——就像解读一样。两者都不会一直稀缺。不会被吸收的，是这个位置：一家华南愿意信任、又没有理由向它推销任何东西的独立诊断机构。
We publish our baselines openly not to defend them, but because open, verifiable work is how that trust is built. The standard a region measures against — earned season after season — is the one advantage that compounds. It is not a dataset. It is a relationship.
我们公开基线，不是为了守住它，而是因为公开、可核验的工作才能建立这份信任。一个地区据以衡量的标准——季复一季地赢得——才是唯一会增值的优势。它不是一套数据，而是一种关系。
"It is not a dataset. It is a relationship."
它不是一套数据，而是一种关系。
Where the baselines are being built. 正在建立基线的作物。
Active Pilot
Dragon Fruit 火龙果 · 五桂山试验点 Wuguishan
The anchor pilot, now sampling. Dragon fruit is a CAM plant with no true leaves and no published sap reference ranges — sampled by cladode age rather than leaf position.
首个试点，现已开始采样。火龙果是CAM植物，无真正叶片，亦无已发表的汁液参考范围——按茎节年龄而非叶位采样。
In Pipeline
Strawberry 草莓 · Pipeline
Protected-tunnel strawberry for the Greater Bay Area's premium pick-your-own market. Actively seeking farm partners for blueberry, lychee, and longan.
面向大湾区高端采摘市场的温室草莓。同时正在寻找蓝莓、荔枝、龙眼的农场合作伙伴。
An independent company, built to stay that way. 一家独立的公司，并且刻意保持独立。
Darren Siu 萧敦仁
Founder & Principal Diagnostic
Darren Siu brings a background in biology and training in functional medicine — a clinical discipline of diagnosing before intervening. The premise that carries over is simple: the method that works on a patient works on a crop. Test first, then decide.
萧敦仁拥有生物学背景，并受过功能医学训练——这是一门"先诊断、再干预"的临床学科。迁移到作物上的前提很简单：对患者有效的方法，对作物同样有效。先检测，再决定。
For partners, labs, and growers. 合作伙伴、实验室与种植者，欢迎联系。
Whether you are a grower who would rather see the data than take our word for it, a lab or supplier, or a partner interested in the dataset — the door is open.
无论您是想亲眼看到数据而非轻信承诺的种植者，还是实验室、供应商，或对数据集感兴趣的合作伙伴——门是敞开的。
