1、Role of soil nutrient elements transport on Camellia oleifera yield

The generated information is expected to provide valuable insights for understanding C. oleifera nutrient contents and fruit characteristics for high-yield and high-quality production, and to provide a theoretical basis and guidance for soil, fertilization, and fruit yield and oil quality improvement of C. oleifera.

2、Role of soil nutrient elements transport on Camellia oleifera yield

Background: Most of Camellia oleifera forests have low fruit yield and poor oil quality that are largely associated with soil fertility. Soil physical and chemical properties interact with each other affecting soil fertility and C. oleifera growing under different soil conditions produced different yield and oil composition.

3、Fertilization shapes microbial life strategies, carbon and nitrogen

Mineral and organic fertilizers as well as microbial inoculations are crucial to maintain and to improve soil health and quality, ecosystem functions, and fruit yield in Camellia oleifera plantations.

4、Effects of Different Fertilizer Combinations on Growth and

This fertilizer combination could effectively increase the fruit size, leaf area, net photosynthetic rate, transpiration rate and contents of nitrogen, phosphorus, potassium, calcium and magnesium in trees, which is conducive to the storage and distribution of tree nutrition.

Role of soil nutrient elements transport on Camellia oleifera

Three main soil types were studied, and redundancy, correlation, and double-screening stepwise regression analysis were used for exploring the relationships between C. oleifera nutrient

gnificant impact on growth and development of Camellia oleifera. He et al. (1996) found that the content of N, P and K varies with growth ages and growing sites, which mainly existed in fruit, flower and leaf. Ding et al. (2012) analyzed the nutrient characteristic of Camellia oleifera planting soil in Guangdong provinc

Effect of Different Formula Fertilizations on Soil Enzyme Activity

To explore the reasonable fertilization technical measures of Camellia oleifera woodland, slow release fertilizer, compound fertilizer, organic fertilizer and fertilizer depth were used as test factors, and different ratios were designed into nine treatments and CK.

Effects of Soil Properties and Nutrients on the Fruit Economic

Our study highlights the importance of considering soil properties and nutrients in the cultivation of C. oleifera and emphasizes the need for rational fertilizer application.

Plantation quality assessment of Camellia oleifera in mid

Camellia oleifera is a woody shrub widely cultivated on subtropical acid soil regions, and its oil is considered to be an “oriental olive oil”. It was once believed that soil is the most important site factor limiting the yield of oil from C. oleifera.

Role of soil nutrient transport on C. oleifera yield and quality under

However, the effect of calcium (Ca²⁺) sugar alcohol (CSA), a newly developed chelated Ca²⁺-fertilizer, on the secondary metabolism of phenolics in T. grandis nuts is largely unknown, for ...

Camellia oleifera, a woody oil-bearing tree species with high economic value, produces tea seeds rich in oil, which are essential for edible oil and biodiesel production. its yield and quality are influenced by various factors, including the use of calcium fertilizers.

I. Why Does Camellia oleifera Need Calcium Fertilizer?

1. Impact on Growth: Calcium, an essential nutrient for plant development, enhances disease resistance, adaptability to adverse conditions, root development, soil water retention, and permeability. This improves both yield and quality.

2. Effect on Fruiting: Calcium fertilizers promote flower bud differentiation, increase flower quantity, and boost fruit setting rates, leading to higher fruit production. They also reduce oil content irregularities in fruits, enhancing oil extraction rates.

3. Oil Quality Improvement: Calcium increases unsaturated fatty acid content in the fruit, elevating the quality of camellia oil, a critical component determined by these acids.

II. Why Might Camellia oleifera Not Bear Fruit?

1. Improper Calcium Use: Excessive or improper application can cause physiological disorders like leaf tip necrosis, fruit drop, and flower drop, disrupting normal growth and fruiting.

2. Soil Conditions: Insufficient soil calcium or poor structure hampers root absorption, affecting growth and fruiting. Calcium uptake relies on adequate soil levels.

3. Pests and Diseases: Damage to leaves and fruits reduces photosynthetic efficiency, negatively impacting growth and fruiting.

III. How to Properly Use Calcium Fertilizer?

1. Soil-Based Selection: Choose calcium fertilizers according to soil calcium content and structure. Acidic soils benefit from alkaline calcium fertilizers, while alkaline soils suit acidic ones. Organic-rich soils absorb calcium more effectively.

2. Rational Application: Apply calcium fertilizers in moderation (20-50 kg per mu) during spring and autumn for optimal growth and fruiting.

3. Combine with Other Fertilizers: Enhance effectiveness by mixing calcium fertilizers with phosphate and potash fertilizers to improve nutrient uptake and growth.

appropriate calcium fertilization is crucial for Camellia oleifera's growth and fruiting. Soil testing, balanced application, and fertilizer integration ensure healthy growth and stable, high yields.
