Camellia odorata seedling cultivation method

Abstract

The invention discloses a method for cultivating camellia oleifera seedlings, and belongs to the technical field of agricultural planting. The method comprises the following technical steps: (1) cultivating cutting seedlings; (2) preparing a seedling substrate; (3) transplanting the cutting seedlings; (4) placing seedling raising bags; (5) seedling culture management; (6) outplanting the seedlings. According to the method, the survival rate of the cutting seedlings is increased, the obtained cutting seedlings are neat and robust, the seedling raising period is short, large seedlings obtained after the cutting seedlings are transplanted and cultivated are good in quality, vigorous in growth vigor, high in height, uniform, full and regular in crown, the cultivation time is short, the survival rate of outplanting and transplanting is high, the afforestation effect is good, and the yield reaching time is short.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for cultivating large seedlings of fragrant flower camellia oleifera. Background technique [0002] Camellia oleifera belongs to the genus Camellia in the family Theaceae, and is a unique woody oil tree species in my country. In my country, Camellia oleifera has a long history of cultivation, and it is known as the world's four largest edible woody oil tree species together with olive, oil palm and coconut. The main product of Camellia oleifera, tea oil, is rich in unsaturated fatty acids, edible, and can prevent cardiovascular diseases. Tea oil is not easy to be oxidized and deteriorated, and it has a strong absorption effect on ultraviolet rays, so it can also be used in skin care products. Camellia oil is known as "Oriental olive oil" because of its high economic value. [0003] Camellia oleifera is a new species of Camellia oleifera disco...

Problems solved by technology

[0004] Patent Publication No. CN 111837783 A discloses a method for cultivating big cup seedlings of camellia oleifera. The 2-year-old big cup seedlings of camellia oleifera cultivated by this method are 50 cm high, 0.6 cm or more in ground diameter, with more than 5 branches and a crown width of 20 cm × 20 cm or more , the quality of seedlings is good, and the survival rate of afforestation is high, but there are still the following problems in the follow-up promotion and planting: ① The placement of seedling bags is not reasonable enough, the placement of seedling bags is compact, and the spacing of seedlings is dense, although it can save cultivation space , but because the growth space of seedlings is limited, the seedlings cannot get enough sunlight, nutrients are insufficient, and the air is not circulated, which is easy to breed diseases and insect pests, making the growth of seedlings slow, the cultivation time is slightly longer, and the growth is not strong enough; ②The cutting substrate only uses yellow Mud, after the cuttings are completed, the watering substrate is easy to harden, the air permeability is not good enough, and the cuttings cannot be provided with sufficient nutrients and water, the survival rate of the cutting seedlings is not high enough, and the seedling raising period is slightly longer; ③The seedling raising substrate is yellow mud and decomposed organic fertilizer , the water retention and air permeability of yellow mud are not good enough, the growth and development of seedlings are not good enough, the growth is not strong enough, the seedlings are not high enough and the crown is not full
