High-yield cultivation method for camellia oleifera

Abstract

The invention provides a high-yield cultivation method for camellia oleifera. The method comprises the following steps: preparing soil, applying a base fertilizer, raising seedlings, adopting a mannerof transplanting the raised seedlings, performing management, spraying a nutrient solution, performing intertillage and weeding, and performing top dressing. The planting method for the camellia oleifera provided by the invention greatly reinforces the survival rate and the growth speed of cutting seedlings through improving a cutting method of the cutting seedlings, and effectively solves the defects of a low survival rate and a slow growth speed of the cutting seedlings in a cold and high-temperature dry climate; the prepared base fertilizer is applied when the cutting seedlings are transplanted into a field, and a proper usage amount of top dressing fertilizers are applied during the flowering and fruiting periods respectively, the growth speed of the camellia oleifera is greatly increased, the camellia oleifera can bear fruits in a third year, the fruiting rate in a first year of fruiting is higher by 7%-12% than that of a current excellent variety, and the oil production is alsohigher than that of current camellia oleifera; and the economic benefits of forest farmers and a camellia oleifera industry are effectively improved.

Description

[0001] The invention relates to the field of agricultural planting, in particular to a high-yield cultivation method for camellia oleifera. Background technique [0002] Camellia oleifera (Camellia oleifera Abel) belongs to the family Theaceae, and its seeds have high oil content. It is an important woody oil economic tree species in southern China. It is also known as camellia oleifera or tea seed tree. ; Bark light brown, smooth, single leaves alternate, leathery, oval or oval-elliptic, with fine serrations on the edge, 3-10cm long, 1.5-4.5cm wide; flowers terminal or axillary, bisexual flowers, White, 6-9cm in diameter, obovate petals, often bilobed at the top; spherical, oblate, olive-shaped capsules, 3-4cm in diameter, thick and lignified petals, containing seeds; Camellia oleifera has a well-developed root system and is resistant to poor soils. It is suitable for a wide range of growth and can make full use of marginal land for growth. It is an excellent tree species wit...

Problems solved by technology

[0003] Planting Camellia oleifera in a wide mountainous area can promote the development of local agriculture and increase the economic income of farmers. However, in the existing traditional planting methods, due to their own limitations, the planting yield of Camellia oleifera is not high, and the oil content is low, which leads to the lack of enthusiasm for planting. high
