Australia (3.9%): Western Australia’s sandy soil dry cropping system
Environmental challenge：
Thermal stress (>35℃ during ear pumping in northern India)
Freeze-thaw erosion (12-15 annual freeze-thaw cycles in the black soil belt of Ukraine)
Salinization (Pakistan Indus Plain ECe>4 dS/m)
Acidification (pH<5.2 in Cerrado region, Brazil)
NO.2 Cross-regional fertilizer demand model (IPNI 2024 standard)
Characteristics of nutritional needs in the reproductive stage, physiological regulation goals
Tillering period N:P:K=4:1:2, sulfur-zinc synergy is required, and the number of tillers ≥3/plant
Critical nitrogen stage during the budding period (the amount of N required accounts for 40% of the whole period) Stalk wall thickness ≥0.35mm
Peak demand for boron and molybdenum during pregnancy (B 0.5ppm), increase in the number of florets
Potassium-magnesium synergy during grouting period (K:Mg=5:1) thousand grains weight≥45g
NO.3 Regional customized fertilization plan
- India’s Ganges Plain Plan
Soil improvement：
Bio-organic fertilizer (WheatPro-5) 2 tons/ha (including trichoderma≥1×100 CFU/g)
Apply before plowing to increase CEC 15-20%
Water and fertilizer management：
Tillering period: NPK 20-10-10 + chelated zinc (0.1% liquid)
Ear pumping period: Functional liquid fertilizer (N 12% + humic acid 8%) foliar spraying
- Russian black calcium soil belt plan
Cold resistance scheme：
Qiu Shi Controlled Release Fertilizer (CRF 22-8-15+2MgO) 400kg/ha
Rejuvenation period: Amino acid chelating agent (proline-enhanced) spray
Data support：
Rostov Test Station (2023): Controlled-release fertilizer increases the survival rate of overwintering to 92%
- The Great Plains Plan of the United States
Precise variable fertilization：
NDVI-guided top dressing system：
Tillering threshold value 0.35: Application N 40kg/ha
Critical value of 0.55 during the extraction period: Shi KOO 25kg/ha
Product adaptation: NPK 32-0-10 water soluble fertilizer (pH 5.8)
- Intensive planting in France
Ecological synergy plan：
Base fertilizer: organic-inorganic compound fertilizer (OM≥30%, NPK 15-15-15)
Top dressing before flowering: liquid fertilizer containing ammonium molybdenum acid (Mo 0.02%)
Nitrogen reduction technology: Reduce urea volatilization through glucosamine regulators 38%
- Pakistan Saline Zone Plan
Salt hazard correction system：
Before colonization: Humic acid leaching agent (75kg/ha) to reduce EC 30%
Fertility period: special formula fertilizer (NPK 18-6-24+TE) anti-salt stress
Supporting measures: ridge work + gypsum improvement (Ca2/Na replacement)
NO.4 Functional product application matrix
Environmental challenge adaptation product mechanism of action
High temperature and heat damage betaine-seaweed complex to maintain cell membrane integrity
Low-temperature freezing damage, proline chelation, osmoregulation, accumulation of substances
Acidified soil calcium silicate conditioner to increase pH 0.5-1.0 units
Drought stress water-retaining biological fertilizer secretes polysaccharide adhesive substances
NO.5 Collaborative standard for intelligent water and fertilizer
Irrigation control parameters (ICID standard)：
Tillering period: soil water content 70-75% θFC
Gestation period: daily water consumption 6-8mm
Water-fertilizer coupling: EC value 1.2→1.8→1.4 dS/m gradient management
Fertilization equipment requirements：
Fertilizer injection pump accuracy error ≤3%
Filter specifications ≥120 mesh (anti-drip head clogging)
NO.6 Empirical data support
Punjab Test, India (2023)：
Use biological fertilizer：
The number of tillers increased by 2.3 per plant
The incidence of rust disease decreased by 67%
Average production increase of 14.5%
Western Australia Project, Australia：
Humic acid liquid fertilizer solution：
Moisture utilization efficiency increased to 22kg/(ha·mm)
The protein content of the grains is stable at 12.5%
This program integrates the latest research results of the International Wheat Improvement Center (CIMMYT) with field verification data from major production areas to meet the needs of different ecological areas through a modular product portfolio.
It has been calculated that the whole process can achieve a nitrogen fertilizer utilization rate of 68% and a phosphorus activation efficiency of 55% (the traditional methods are 42% and 31%, respectively).The specific implementation needs to be dynamically adjusted in combination with the characteristics of local varieties and the farming system.
The stalks of wheat fields with customized formula fertilizer are stout and upright, the resistance to lodging is increased by 50%, and the incidence of rust disease is reduced by 40%；
The effective tillering number of a single plant increased by 35%, the wheat ears were full and uniform, and the yield per ha exceeded the high-yield threshold of 8 tons.；
The protein content of the grains reached 14.5%, the starch conversion rate increased by 20%, and the dietary fiber content of bran exceeded 12%, which meets the national first-class gluten wheat standard (GB/T 17892).
