CROP PROGRAMS
Eight crops,
eight phenology tables
Each programme assigns a nutrition layer to every phenological stage. The same product appears in several programmes — what changes is the timing and the rate.
GRAPE
Grape葡萄
From budbreak to veraison, nutrition has to follow phenology. Rain-shelter and open-field growing differ mainly in root activity and calcium partitioning.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Budbreak – shoot growth | Root activation, continued flower-bud differentiation | Seaweed biostimulant + high-P |
| 02 | Flowering – fruit set | Flower quality, fruit set, calcium partitioning to berries | Ca-B + amino acids |
| 03 | Berry fill – veraison | Sugar accumulation, even colour, bloom on the skin | Organic K / PK + colour-signal complex |
| 04 | Post-harvest – dormancy | Replenishing storage reserves in the vine | Balanced WSF + organic carbon |
- 01Pushing potassium at veraison while ignoring calcium partitioning — cracking and sunburn follow.
- 02Excess nitrogen before flowering: shoot vigour competing directly with fruit set.
CITRUS
Citrus柑橘
An evergreen crop: roots stay active almost all year, so timing is set by flushes rather than seasons.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Spring flush – pre-bloom | Flush quality and flowering support | Balanced WSF + B / seaweed |
| 02 | Petal fall – fruit set | Reducing physiological drop | Ca-B + amino acids |
| 03 | Fruit growth – autumn flush | Sizing fruit while feeding the autumn flush | High-K + organic K |
| 04 | Colour break – harvest | Brix and peel colour | PK + colour-signal complex |
- 01Treating an evergreen crop as seasonal: root feeding stops exactly when the autumn flush needs it most.
- 02Applying calcium only as a foliar spray while the soil is dry — uptake is a root process.
TOMATO
Tomato番茄
Yield is decided at flower initiation; quality at the potassium-to-calcium ratio.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Seedling – transplanting | Root establishment after transplanting | Root promoter + high-P |
| 02 | Flowering – fruit set | Truss quality and fruit set | Ca-B + B |
| 03 | Fruit fill – harvest | Size, colour and dry matter | High-K + organic K |
| 04 | Post-harvest recovery | Restoring the plant for the next truss | Amino acids + organic carbon |
- 01Chasing size with potassium only: fruit colours unevenly and stores badly.
- 02Skipping calcium during rapid truss growth — blossom-end rot appears two weeks later.
STRAWBERRY
Strawberry草莓
Shallow-rooted and salt-sensitive: the nursery stage decides the second half of the season.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Nursery – flower differentiation | Flower-bud initiation | High-P + seaweed |
| 02 | Transplant – establishment | Rooting and transplant stress | Root promoter + organic carbon |
| 03 | Flowering – fruit set | Fruit set and firmness | Ca-B + B |
| 04 | Harvest period | Brix, colour and shelf life | Organic K + colour-signal complex |
- 01High EC at establishment: shallow roots burn before they reach the drip line.
- 02Feeding only nitrogen through harvest — fruit softens and sugars plateau.
CUCUMBER
Cucumber黄瓜
A continuously fruiting crop: what matters is rhythm, not any single dose.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Seedling – transplanting | Root establishment | Root promoter + organic carbon |
| 02 | First fruit | Balanced vegetative and reproductive growth | Balanced WSF |
| 03 | Peak harvest | Holding size and quality under continuous picking | High-K + organic K |
| 04 | Low-light / cold spell | Photosynthesis and stress tolerance | Amino acids + silicon |
- 01Heavy potassium during a cold, low-light spell — plants stall instead of setting fruit.
- 02Irrigating with a high-EC solution in cold soil: root activity drops before symptoms show.
APPLE
Apple苹果
Bitter pit is not a disease. It is uneven calcium distribution.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Budbreak – bloom | Flower quality and fruit set | B + seaweed |
| 02 | Young fruit | Cell division and calcium allocation | Ca + B |
| 03 | Fruit enlargement | Size and sugar accumulation | High-K + PK |
| 04 | Pre-harvest | Colour, firmness and storage quality | Organic K + Ca |
- 01One late calcium spray instead of a season-long allocation strategy.
- 02Excess potassium in the second half competing with magnesium and calcium uptake.
CHERRY
Cherry樱桃
Fifty-odd days from bloom to harvest: there is no second decision.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Pre-bloom | Flower quality and set | B + seaweed |
| 02 | Petal fall – pit hardening | Cell division, reducing drop | Ca + high-P |
| 03 | Swelling – colour | Size, firmness and colour | Organic K + Ca |
| 04 | Post-harvest | Rebuilding reserves for next season | Amino acids + organic carbon |
- 01Waiting for visible colour to start potassium — sizing is already finished by then.
- 02Neglecting post-harvest nutrition: next year's flower buds are initiated now.
WATERMELON
Watermelon西瓜
Brix comes from potassium and carbohydrate supply arriving in step.
| # | Stage | Objective | Direction |
|---|---|---|---|
| 01 | Seedling – vine growth | Root and vine establishment | Balanced + root promoter |
| 02 | Flowering – fruit set | Fruit set and early cell division | Ca-B + B |
| 03 | Fruit swelling | Size and yield | High-K |
| 04 | Pre-ripening | Brix and flesh quality | Organic K + PK |
- 01Nitrogen close to ripening: vine overgrowth, hollow fruit and low brix.
- 02Cutting water and potassium too early — fruit stops sizing in the final week.
