1、Reducing nitrogen fertilization of intensive kiwifruit orchards decreases nitrate accumulation in soil without compromising crop production

We concluded that the current level of N fertilization in kiwi orchards is very excessive, and reducing the N fertilizer rate by 25–45% could not only guarantee fruit yield, but also reduce N accumulation and loss.

2、A Case for Silicon Fertilization to Improve Crop Yields in Tropical Soils

Application of silicon fertilizer increases the dry weight of barley by 21 and 54 % over 20 and 30 days of growth, respectively, relative to plants receiving no supplemental silicon [101].

3、Eco

Our analysis revealed fertilizer use and N-associated emissions as the hot spots for GHG emissions from kiwifruit orchards in the main kiwifruit growing region in New Zealand.

Effect of Silicon Fertilization on Crop Yield Quantity and Quality—A Literature Review in Europe

In recent years, more research has been performed with regards to foliar nutrition using silicon, which brings unequivocal production benefits, and at the same time is much cheaper and more convenient to use than soil fertilization. As a result, it improves the profitability of many plant species’ production.

Effects of different fertilizations on fruit quality, yield and soil fertility in field

Balanced fertilization with N, P, K and organic manure is important to soil fertility, which may increase yield and improve quality in field-grown kiwifruit orchard. Keywords: different fertilizations, kiwifruit yield, quality, soil fertility DOI: 10.3965/j.ijabe.20171002.2569

Study on the effect of soil beneficial microorganisms on the growth of kiwifruit

Microbial fertilizer is used to optimize the microbial in the soil, and to further improve the effect of the beneficial microorganism on the plant. Microbial life activities are used to continuously improve the survival environment of plant rhizosphere and the absorption of nutrient elements.

Seasonal accumulation of mineral nutrients by kiwifruit

While values for the nutrient composition of mature kiwifruit are documented (Ferguson, 1984; Smith, Asher & Clark, 1987 a), and the relative partitioning of nutrients between fruit and struetural components in younger vines established by destructive har-

Effect of Silicon on Crop Growth, Yield and Quality

Liu (1997) conducted several field trials to compare the effects of Si and Ca fertilizer on tomato growth, yield and quality. The results showed that the application of Si fertilizer significantly increased tomato resistance to diseases, fruit size and consequently yield.

High rates of N fertiliser applied to kiwifruit vines (A. deliciosa) over four seasons tended to produce larger fruit (5% heavier on average over the four seasons) mainly due to increased water content with less effect on total dry matter contents.

SmartFresh SM brings several benefits to both green and yellow fleshed cultivars of kiwifruit including: fruits remaining firmer throughout storage and shelf life with no negative effect on physiological disorders and rots; reduced fruit losses owing to soft fruit; replacement of CA storage for medium-term storage and shipment; optimized storage...

Kiwifruit is a nutrient-rich, uniquely flavored fruit beloved by consumers. its growth demands high nutrient levels, particularly silicon fertilizer, which plays a critical role in kiwifruit development. Silicon fertilizers promote fruit enlargement, enhance coloration, and improve both quality and yield. Below are detailed guidelines for optimizing silicon fertilizer use to boost kiwifruit productivity and quality:

I. Selecting the Appropriate Type of Silicon Fertilizer

1. Silicate-Type Silicon Fertilizer: High in silicon content, this fertilizer provides abundant silicon for plant absorption. It serves as the primary silicon source for kiwifruit cultivation.

2. Silicon Compound-Type Fertilizer: Containing compounds like sodium silicate or diatomaceous earth, this fertilizer offers comprehensive silicon supplementation. It can be used as a supplementary silicon source.

3. Organic Silicon Fertilizer: Rich in organic matter, this fertilizer improves soil structure and water/nutrient retention. It serves as a complementary silicon source in kiwifruit farming.

II. Rational Application of Silicon Fertilizer

1. Dosage Control: Based on soil tests and kiwifruit growth requirements, apply 1–3 kilograms per mu (0.0667 hectare) of silicon fertilizer to meet plant needs.

2. Timing: Apply silicon fertilizer during critical growth stages: pre-flowering, fruit enlargement, and ripening periods to maximize growth and fruit development.

3. Application Methods:

   • Mix silicon fertilizer with organic fertilizers and broadcast or furrow-apply evenly.
   • Alternatively, foliar spray silicon fertilizer to enhance absorption efficiency.

III. Optimizing Soil Conditions

1. Soil Improvement: Prioritize soil aeration and water retention by deep tilling and adding organic matter.

2. Soil Testing: Analyze soil silicon content, pH, and other indicators before application to refine dosage and methods.

3. Irrigation Management: Maintain soil moisture without overwatering, as excessive irrigation can cause compaction and reduce silicon uptake.

IV. Enhanced Management Practices

1. Pest and Disease Control: Combine silicon application with integrated pest management (e.g., biological control) to minimize crop damage.

2. Water Regulation: Balance irrigation and drainage to avoid water stress during kiwifruit growth.

3. Pruning and Thinning: Remove weak or overcrowded fruits to ensure quality. Improve airflow and light penetration for better fruit development.

V. Post-Harvest Management

1. Timely Harvest: Pick ripe fruits promptly to prevent overripening and spoilage. Handle harvested fruits carefully to avoid contamination.

2. Post-Harvest Processing: Clean, grade, and package fruits to enhance market competitiveness.

3. Storage and Transport: Maintain optimal humidity and temperature to prevent mold or degradation. Implement pest-proof measures to preserve fruit safety and quality.

Silicon fertilizers significantly enhance kiwifruit growth, yield, and quality. To maximize benefits, select appropriate fertilizer types, apply rationally, optimize soil conditions, strengthen management practices, and manage post-harvest processes. These integrated strategies amplify the role of silicon in kiwifruit production, delivering superior results.
