What type of fertilizer is better for Camellia oleifera trees
An introduction to the green plant and flower aspect of what kind of fertilizer is better for Camellia oleifera trees, following this guide to understand together.
What type of fertilizer is better for Camellia oleifera trees
Mainly use decomposed organic fertilizer, adhere to the principle of combining fast-acting fertilizer with slow-acting fertilizer, and combining organic fertilizer with inorganic fertilizer to achieve better fertilization results. Camellia oleifera trees can be unfertilized in the first year after planting. Under conditions, some thin human waste water can be watered appropriately in June to July after the seedlings recover, or 25 to 50 grams of urea or special fertilizer can be applied per plant. In the following years, apply fast-acting nitrogen fertilizer about half a month before the new shoots germinate in March.
Camellia oleifera is a evergreen small tree belonging to the Camellia genus of the Theaceae family, a unique subtropical species in China, and one of the world's four major woody oil crops.
Currently, Camellia oleifera trees are the main pure natural high-grade oil crop species in Zhejiang, Henan, Jiangxi, Guangxi, and Hunan provinces. They are generally propagated by grafting with Camellia flowers and cultivated artificially.
Currently, the market price of tea oil is quite high, which is directly related to its scarcity. The geographical environment and management of planting Camellia oleifera are particularly important. The management of Camellia oleifera is relatively simple, maintaining sufficient soil nutrients can basically ensure a bountiful harvest.
What type of fertilizer is generally used for Camellia oleifera trees
Camellia oleifera trees are most afraid of chlorine-containing fertilizers, which can cause poor growth and quality decline in the trees.
① Nitrogenous fertilizers should preferably be nitrate ammonia, and the use of chloride ammonia is prohibited.
② Potash fertilizers generally use sulfate potassium and nitrate potassium, and chloride potassium cannot be used.
③ For ternary compound fertilizers, sulfate potassium type compound fertilizers are generally used, and chloride potassium type compound fertilizers cannot be used.
Fertilization for Camellia oleifera trees mainly uses organic fertilizers, such as cake fertilizer, humus soil, or decomposed farm manure, with nitrogenous fertilizers applied during the vegetative growth period.
In the seedling stage of Camellia oleifera trees, generally apply decomposed human waste water, and when entering the fruiting stage, nitrogen and potassium fertilizers are mainly used, combined with ternary compound fertilizers to promote flowering and fruiting.
Fertilization principles and methods for Camellia oleifera trees
Fertilizers are divided by nature into organic fertilizers, inorganic fertilizers, and microbial fertilizers. Inorganic fertilizers can be divided into macronutrient fertilizers such as nitrogen, phosphorus, and potassium, and some medium and trace element fertilizers.
Camellia oleifera not only needs macronutrient fertilizers but also requires an appropriate amount of medium and trace elements.
Rational combination of various nutrients can create good conditions for the growth and development of Camellia oleifera, promoting its robust growth and increasing yield. Studies have shown that the combined application of nitrogen, phosphorus, and potassium nutrients has a significantly better effect than the cumulative effect of each single element.
① For young Camellia oleifera forests
Fertilization in young forests should focus on decomposed organic fertilizers, combining fast-acting and slow-acting fertilizers, and organic and inorganic fertilizers to achieve better fertilization results.
② Fertilization for mature Camellia oleifera forests
Fertilization during the peak fruiting stage of Camellia oleifera should have a reasonable ratio of nitrogen, phosphorus, and potassium, with a general ratio of 10:6:8 being better. Fertilization should adhere to several principles: fertilizing based on the mountain, the tree, the fertilizer, and the season.
③ Fertilization for low-yield Camellia oleifera forests
Mainly use farm manure and carry out winter tillage.
④ Fertilization method
The root system of Camellia oleifera is well-developed, with absorbent roots mainly distributed in the soil layer from 5 to 30 centimeters, with the area near the projection of the tree crown being dense. The root system has a distinct water and fertilizer-driven property.
Generally, a circular trench about 20 centimeters deep and wide is dug along the inner edge of the tree crown projection, and the fertilizer is directly applied into the trench. Fill in the soil to cover.
The above introduction to the better fertilization methods for Camellia oleifera trees can be used as a reference suggestion.
