1、A Complex Inoculant of N2

This study aimed to evaluate the capacity of PGPB, identified by phenotypic and 16S rRNA sequencing from a vegetable purple soil in Chongqing, China, to increase soil nitrogen (N), phosphorus (P), and potassium (K) availability and growth of kiwifruit (Actinidia chinensis).

2、Sucrose

Southern hybridisations in a diploid relative of kiwifruit, Actinidia chinensis (Planch.) var. chinensis, were consistent with the presence of a small gene family. Western analysis indicated a 125 kDa SPS protein present in all tissues of A. chinensis at all stages of development.

3、Kiwifruit (Actinidia spp.) vine and fruit responses to nitrogen fertiliser applied to the soil or leaves : a thesis presented in partial fulfilment of the

In plants, N fertilisation can reduce carbohydrate levels and increase succulence. Therefore high levels of N fertilisation could reduce fruit DM% by reducing its dry matter accumulation and increasing its water content.

Exogenous cytokinin application to Actinidia chinensis var. deliciosa ‘Hayward’ fruit promotes fruit expansion through water uptake

Exogenous application of a cytokinin-like compound forchlorfenuron (CPPU) can promote fruit growth, although often at the expense of dry matter (DM), an important indicator of fruit quality.

Physiological responses of kiwifruit vines (Actinidia chinensis Planch. var. chinensis) to trunk girdling and root pruning

We hypothesized that in kiwifruit, trunk girdling manipulates carbohydrate partitioning, thereby reducing sink demand and resulting in reduced photosynthesis.

Fate of 15N

Temporal changes in the nitrogen (N) and 15 N content of various components of six-year-old kiwifruit (Actinidia deliciosa ‘Hayward’) vines which had received 15 N-labelled ammonium fertilizer were measured.

Effects of pre

The effects of ethephon, abscisic acid (ABA), and nordihydroguaiaretic acid (NDGA) application on the ripening of pre-harvest ‘Kohi’ kiwifruit (Actinidia chinensis) were studied.

‘HORT16A’ KIWIFRUIT: PROGRESS AND ISSUES WITH COMMERCIALISATION

Various biological characteristics of the vine and the fruit have contributed to its rapid commercialisation. ‘Hort16A’ fruit have distinctive features of appearance and taste that are readily distinguishable from ‘Hayward’ fruit. It is more productive than ‘Hayward’.

Uptake of 15N by Kiwifruit Vines from Applications of Nitrogen Fertilizer Prior to Budbreak

Abstract Mature field-grown kiwifruit vines (Actinidia deliciosa var. deliciosa cv. Hayward) were fertilized with 15 N-labelled fertilizer (ammonium sulphate, 10 atom % 15 N, 50 kgN ha -1) to investigate the timing of uptake of fertilizer nitrogen (N) and its availability for new season's growth.

Gold kiwifruit (Actinidia chinensis ‘Hort16A’) for immune support

Consumption of green kiwifruit can have positive effects on cardiovascular health through antioxidant activity, inhibition of platelet aggregation and lowered TAG levels, and gut health through improving laxation, aiding digestion and promoting a healthy gut microflora.

Kiwifruit (Actinidia chinensis), also known as "kiwi," "miracle fruit," or "hairy peach," is a nutrient-dense, uniquely flavored fruit. Rich in vitamin C, dietary fiber, trace elements, and antioxidants, it offers numerous health benefits. In agricultural production, scientific fertilization is critical to improving fruit quality and yield. Phosphate fertilizer, as a key nutrient source, plays a vital role in promoting plant growth and enhancing pest/disease resistance. Below is a detailed guide on fertilization methods for kiwifruit, including precautions for using phosphate fertilizer.

I. Fertilization Principles

1. Balanced Fertilization: Follow the principle of balancing nitrogen (N), phosphorus (P), and potassium (K) to meet the nutritional needs of different growth stages.
2. Combine Organic and Chemical Fertilizers: Organic fertilizers provide comprehensive nutrients, while chemical fertilizers act quickly. Using both yields optimal results.
3. Demand-Based Fertilization: Adjust fertilizer types and amounts based on plant growth, soil fertility, and climatic conditions.
4. Deep Application and Topdressing: Deep application of organic fertilizers improves soil structure, while topdressing targets specific growth phases.

II. Fertilization Methods

1. Base Fertilization:

   • Apply before planting, primarily using organic fertilizers (e.g., compost, green manure) with added phosphate fertilizer. Base fertilizer ensures long-term, stable nutrient supply.

2. Topdressing:

   • Budding Stage: Promote root development with compound fertilizers or phosphate-containing blends.
   • Flowering and Fruiting Stage: Use high-phosphorus fertilizers (e.g., diammonium phosphate) to support flower differentiation and fruit development.
   • Fruit Enlargement Stage: Enhance fruit size and sweetness with potassium-rich fertilizers (e.g., potassium sulfate).

3. Foliar Spraying:

   • For micronutrient deficiencies, apply phosphate-rich solutions directly to leaves.

III. Precautions

1. Avoid Over-Fertilization: Excessive phosphate can disrupt soil structure and harm microbial activity.
2. Scientific Combination: Pair phosphate fertilizer with nitrogen/potassium fertilizers to prevent nutrient imbalance.
3. Soil Testing: Regularly test soil for nutrient content and pH to refine fertilization strategies.
4. Weather Considerations: Reduce fertilization during drought or heat to avoid damage.
5. Safety Measures: Wear protective gear (gloves, goggles) when handling fertilizers.

Kiwifruit fertilization should prioritize balance, combine organic/chemical fertilizers, tailor applications to needs, and emphasize safety. Proper management boosts fruit quality, yield, and economic returns for farmers.
