1、A plan for efficient use of nitrogen fertilizers

A global analysis finds that nitrogen fertilizers could be used more efficiently if their international distribution across croplands was altered — a measure that would also decrease...

2、Analysis of fragrance composition in three cultivars of Osmanthus fragrans Albus group flower by gas chromatography

With supercritical CO 2 fluid extraction (SCFE), essential oil was extracted from three cultivars of Xianning osmanthus. The fresh osmanthus flower was processed with a petroleum ether digestion method to produce the extractum. The yields of essential oil and extractum were 0.19 % and 0.13 % (m/m) respectively.

3、Mixing Manure with Chemical Fertilizers, Why?and What is After?

Scattered references can be found in this paper on the effects of the integrated use of organic manure and chemical fertilizers on cultivation of crops. How this particular fertilization treatment affects the changes in physical properties of the soil, water use eficiency, nitrogen use eficiency and plant growth is also being covered.

4、The Emission of the Floral Scent of Four Osmanthus fragrans Cultivars in Response to Different Temperatures

To investigate the influence of temperature on the emission of the floral scent of Osmanthus fragrans, the number of chemical compounds and their relative release amounts from four cultivars of O. fragrans under different temperature treatments, were identified using the solid-phase microextraction (SPME) technique and gas chromatography-mass ...

5、<i>Osmanthus fragrans</i> ‘Cai Ye Gui’, A Variegated Cultivar

The flowers of sweet osmanthus have long been used for traditional Chinese medicine as an herbal tea remedy, in Chinese cuisine as osmanthus-scented jam, and in northern India as an insect repellent (Royal Botanic Gardens, Kew, 2017; Zhou, 2008).

Fertilizers And The Efficient Use Of Water

To accomplish better use of water, production of dry matter or salable crop must be increased per unit of water used in evapotranspiration or for irrigation in semiarid and desert areas. Whether fertilizers affect evapotranspiration depends, it appears, on whether the larger plant has the opportunity to intercept advected heat.

ADOPTION OF IMPROVED AQUACULTURE PRACTICES BY SHRIMP FARMERS IN SOUTH KONKAN REGION MAHARASHTRA, INDIA

This paper discusses the planting technologies and utilization methods of Osmanthus fragrans in ancient China, and discovered that the China’s ancients used the snow and silkworm excrement to fertilize the osmanthus fragrans, used the graft means to breed the red osmanthus, and put the pounded flowers into a new jar which was laid in cold ...

Transcriptomic Analysis of the Candidate Genes Related to Aroma Formation in Osmanthus fragrans

Recently, the germplasm resources, classification, and aroma compositions of O. fragrans have been investigated. However, the molecular mechanisms of the floral scent formation and regulation have remained largely unknown.

Water

Water-soluble essential oil components of Osmanthus fragrans fresh flowers were recovered from the hydrolate and the cold infusion, byproducts of essential oil isolation and concrete extraction, respectively. Chemical investigation was performed by gas chromatography (GC) and gas chromatography – mass spectrometry (GC-MS).

Essential Oil Composition of Osmanthus fragrans Varieties by GC

Osmanthus fragrans oil is very expensive and accordingly is used in only the most expensive perfumes and flavors. Osmanthus fragrans has a number of pharmacological effects such as easing 2009 Vieweg+Teubner | GWV Fachverlage GmbH pain, relieving coughs, neuroprotection and reducing aging [1, 2].

Nitrogen fertilizer is an essential nutrient source that primarily provides nitrogen, a key element for promoting plant growth and development. for flowers like Osmanthus fragrans (sweet osmanthus), nitrogen fertilizer is not ideal. This is because osmanthus has relatively low nitrogen requirements. Excessive nitrogen can lead to overly rapid growth, compromising its aesthetic appeal and floral quality. Instead, phosphate and potassium fertilizers are more suitable for osmanthus.

How to Properly Water Osmanthus? Here are some guidelines:

1. Watering Principle: Osmanthus prefers moist soil but cannot tolerate waterlogging. Follow the "water when dry, keep moist but not soaked" rule: water promptly when the soil surface dries, maintaining even moisture without standing water. Avoid watering during hot weather to prevent root rot.

2. Watering Frequency: Osmanthus grows slowly, so watering should be less frequent. Generally, water every 7–10 days during spring and summer, and reduce frequency in autumn and winter. After each watering, pat the soil surface dry to prevent excess moisture around the roots.

3. Watering Method: Use a fine sprayer or a gentle stream of water to avoid splashing droplets onto leaves, which can invite disease. Check the weather forecast before watering to avoid overlapping with rainfall.

4. Water Amount: For potted osmanthus, water until the soil is thoroughly moistened but not saturated. If the soil surface dries but moisture remains at the pot’s base, reduce watering frequency.

5. Water Quality: Use rainwater or filtered tap water. Avoid hard water with high mineral content, as minerals can harm roots and disrupt nutrient absorption.

6. Drainage Management: Ensure pots have proper drainage holes. If lacking drainage, add a layer of gravel or ceramic particles at the bottom to improve water flow and prevent root rot.

proper watering of osmanthus requires attention to principles, frequency, techniques, volume, water quality, and drainage. By following these practices, osmanthus can thrive healthily, enhancing its ornamental value.
