1、Study on the Effect of Sheep Manure and Chemical Fertilizer on Growth and Fruit Quality of Grape

In this paper,5 years old "Kyoho" grape were taken as research object to study the effect of sheep manure and chemical fertilizer on growth and fruit quality of grape using different sheep manure, urea and diammonium phosphate orthogonal design.

2、Effects of nitrogen and irrigation on the quality of grapes and the susceptibility to Botrytis bunch rot

Therefore, nitrogen fertilization and irrigation of vineyards should be undertaken carefully to avoid negative effects and apply the best management practices that optimize N use and irrigation efficiency. The results of this study showed that a dosage of 150 kg/ha of ammonium nitrate is recommended in sandy loam soils with a relatively high pH.

3、Sduty on effect of water

In this study, water consumption, growth index, yield under different treatments were measured and analyzed in order to investigate the effect of coupling of water and fertilizer on grape growth and water consumption and select the optimal ratio of water and fertilizer.

4、Practices, perceptions, and implications of fertilizer use in East

Our survey results have indicated that excessive nitrogen fertilizer use remains a serious issue in the study regions, accompanied by a lack of applying organic fertilizers and the implementation of better fertilizer application practices.

5、A review of the use of biostimulants in the vineyard for improved grape and wine quality: effects on prevention of grapevine diseases

Foliar application of biostimulants (including resistance inducers or elicitors) in the vineyard has become an interesting strategy to prevent plant diseases and improve grape quality on the grapevine.

Fertilizer using intensity and environmental efficiency for China’s agriculture sector from 1997 to 2014

It is of great importance to investigate effect of fertilizer using intensity on the environmental efficiency of China’s agriculture. This paper mainly investigates the determinants of environmental efficiency of China’s agriculture.

Effects of a controlled

t uptake, and fertilizer usage efficiency for early ripening rapeseed (Xiangzayou 1613) in the red-yellow soil of southern China during 2011–2013. It was grown using a soluble fertilizer (SF) and the same amounts of CRF, such as SF1/ RF1 (3750 kg/hm2), SF2/CRF2 (3000 kg/hm2), SF3/CRF3 (2250 kg/hm2), SF4/

Guidelines for fertilizer use in vineyards based on nutrient content of grapevine parts

Plant analysis plays a major role in fertilizer recommendations for perennial tree crops and vines. Plant analysis, however, does not quantify the rate of nutrients to apply.

Spatiotemporal Coupling of Water and Fertilizer for Double

This paper summarizes the research progress and major achievements of the coupling effect of water and fertilizer on grape cultivation in China and abroad in recent years, emphatically analyzes the application status and some problems of the coupling effect of water and fertilizer on double-cropping grape cultivation mode in Guangxi Zhuang ...

Lu, C; Tian, H (2016): Half

We therefore develop a global time-series gridded data of annual synthetic N and P fertilizer use rate in croplands, matched with HYDE 3,2 historical land use maps, at a resolution of 0.5º latitude by longitude during 1900-2013.

Jiangsu grape specialty fertilizer is a formulated product designed specifically for grape cultivation. It contains essential nutrients such as nitrogen (N), phosphorus (P), potassium (K), microelements, and organic matter to meet the nutritional needs of grapevines at different growth stages. Proper use of this fertilizer promotes healthy growth, fruit development, and enhances both yield and quality. Below are detailed guidelines for application and dosage:

I. Soil Preparation

1. Soil Testing: Before applying the fertilizer, test the soil to determine nutrient levels and pH. This can be done through professional soil testing services.
2. Soil Adjustment: If soil nutrients are deficient or pH is unsuitable, amend the soil with organic fertilizers or specialized additives. For example:
   • Organic fertilizers improve soil structure, aeration, and water retention.
   • Adjusting pH optimizes nutrient absorption by plants.

II. Timing and Methods of Application

1. Timing:

   • Apply in early spring before bud break and after harvest in autumn. These periods are critical for supporting growth and fruit development.

2. Methods:

   • Broadcast and Incorporate: Spread the fertilizer evenly over the soil surface and work it into the soil.
   • Foliar Spray: Dissolve the fertilizer in water according to recommended dilution ratios and spray onto vines.
   • Drip Irrigation: For larger vineyards, apply via drip irrigation to reduce nutrient loss and environmental impact.

III. Dosage and Ratios

1. Dosage:

   • Annual application per vine: 5–10 kg (adjust based on climate, soil type, and grape variety).

2. Ratios:

   • Mix with other fertilizers for balanced nutrition. Examples:
     • 1:1 ratio with organic fertilizers.
     • 1:2 ratio with chemical fertilizers.
   • This approach minimizes environmental pollution while ensuring adequate nutrition.

IV. Key Considerations

1. Avoid Overapplication: Excessive use leads to salt buildup, poor soil structure, and stunted growth. Follow recommended rates strictly.
2. Match Fertilizer Type to Needs: Ensure the fertilizer’s properties align with grapevine requirements. Avoid harmful formulations.
3. Follow Manufacturer’s Instructions: Different brands may have specific dosage guidelines. Always read labels carefully.
4. Safety Precautions:
   • Avoid skin contact. If exposed, rinse thoroughly with water and seek medical help.
   • Do not use fire or water to clean spills, as this may worsen damage.
5. Complement with Other Fertilizers:
   • Add phosphorus-rich fertilizers to promote root development.
   • Use potassium-rich fertilizers to boost disease resistance.
6. Monitor Results: Track plant growth and soil conditions regularly. Adjust strategies if issues arise (e.g., poor response or negative effects).
7. Environmental Factors:
   • Avoid fertilizing during hot weather to prevent moisture loss and concentration shock.
   • Minimize dust pollution during application.
8. Regulatory Compliance: Adhere to local environmental laws and agricultural policies. Avoid illegal or excessive fertilizer use.
9. Scientific Blending: Tailor nutrient ratios to growth stages:
   • Spring: Increase nitrogen for shoot growth.
   • Post-Harvest: Add phosphorus for fruit maturation.
   • Winter: Supplement potassium for cold resistance.
10. Optimal Application Frequency:
    • Annual dosage per mu (0.067 hectares): 10–15 kg.
    • Adjust frequency by season (e.g., reduce/stop applications in winter dormancy).

By following these guidelines, Jiangsu grape specialty fertilizer can maximize yields and fruit quality while promoting sustainable viticulture practices.
