What fertilizer is better for tea tree oil (what fertilizer is better for tea tree oil to grow faster)

The oil tea tree is an evergreen small tree belonging to the genus Camellia of the family Theaceae. It is a subtropical tree species unique to my country and one of the four major woody oil crops in the world.

At present, the oil tea tree is the most important pure natural high-grade oil tree species in Zhejiang, Henan, Jiangxi, Guangxi and Hunan provinces. It is usually cultivated by grafting camellia seedlings.

At present, the market price of tea oil is quite expensive, which is directly related to its scarcity. The geographical environment and management are particularly important for growing tea oil. The management of tea oil is relatively simple. Maintaining sufficient soil nutrients will basically ensure a good yield.

What fertilizers are usually used for tea tree oil?

Tea oil trees are most afraid of fertilizers containing chlorine, which will cause poor growth and deterioration in quality.

① The best nitrogen fertilizer to apply is ammonium nitrate, and ammonium chloride is prohibited .

② Potassium fertilizers generally used are potassium sulfate and potassium nitrate, and potassium chloride cannot be used .

③Ternary compound fertilizer generally uses potassium sulfate type compound fertilizer, and potassium chloride type compound fertilizer cannot be used .

The main fertilizer for fertilizing tea oil trees is organic fertilizer, generally cake fertilizer, humus soil or decomposed farmyard manure, and nitrogen fertilizer is applied during the nutritional growth period.

During the seedling stage of tea oil trees, decomposed human manure is usually applied. When it enters the fruiting period, nitrogen and potassium fertilizers are mainly used in combination with the application of triple compound fertilizer to promote flowering and fruiting.

Principles and methods of fertilizing tea oil trees

Fertilizers can be divided into organic fertilizers, inorganic fertilizers, and microbial fertilizers according to their properties. Inorganic fertilizers can be further divided into nitrogen, phosphorus, and potassium macronutrient fertilizers and some medium- and trace-element fertilizers.

During the growth process of tea oil, not only a large amount of fertilizer is needed, but also appropriate medium and trace elements.

Reasonable combination of nutrients can create good conditions for the growth and development of oil tea, promote its healthy growth and increase yield. Studies have shown that the effect of combined application of nitrogen, phosphorus and potassium nutrients is significantly better than the cumulative effect of each single element.

①Young tea plantation stage

Fertilization of young forests should be based mainly on decomposed organic fertilizers, combining quick-acting fertilizers with slow-acting fertilizers, and organic fertilizers with inorganic fertilizers, so as to achieve better fertilization effects.

② Fertilization of mature camellia oleifera forests

During the peak fruit-bearing period of tea oil, nitrogen, phosphorus and potassium should be properly proportioned. Generally, the ratio of nitrogen, phosphorus and potassium is 10:6:8. There are several principles to be followed in fertilization: fertilize according to the mountain, fertilize according to the tree, fertilize according to the fertilizer, and fertilize according to the season.

③ Fertilization for transformation of low-yield camellia forests

Mainly based on farmyard manure, it is carried out during winter reclamation.

④ Fertilizer method

The root system of tea oil tree is well developed, with the absorbing roots mainly distributed in the soil layer of 5 to 30 cm and a dense area near the projection of the crown. The root system has obvious ability to drive water and fertilizer.

Generally, a circular trench with a depth of about 20 cm and a width is dug along the inner edge of the tree crown projection, and fertilizer is directly applied into the trench. Then the soil is backfilled and covered.
