Camellia oleifera cultivation and pruning method

Abstract

The invention relates to a camellia oleifera cultivation and pruning method. The method comprises four steps of digging holes and beginning to grow, fertilizing, planting, and trimming and pruning, wherein the process of trimming and pruning involves main trunk determining in early stage, and main branch pruning; in the second year of the plantation, the tree seedling is treated with the main trunk determining in a height of 25cm- 30cm; in the third year of the plantation, the tree seedling is treated with the main trunk determining in a height of 30cm- 40cm; the main branch of the camellia oleifera is treated by allowing the portion with green leaves to be exposed in soil, and removing the central branches, that is a treatment like opening a skylight, and the central branches of the maintrunk and side branches uniformly axially distributed around the periphery of the main brunch are pruned, thereby exposing the branches of an inner layer; three to four exuberant side branches are selected and reserved to be cultivated as main branches; and for each layer of main branches, three to four main branch buds in different directions are selected and reserved to form into side branches,and gradually form a good-shaped tree with a lower tree height and an opening tree crown. According to the camellia oleifera cultivation and pruning method, the process of camellia oleifera cultivation and pruning is improved, close planting and brachysm are carried out, the fertilizer, water and nutrition are reserved, thereby improving the survival rate and fruiting rate of camellia oleifera toachieve stable yield and high yield.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation and pruning method for camellia oleifera. Background technique [0002] Camellia oleifera belongs to the family Theaceae, and is an evergreen small tree. Because its seeds can be squeezed for oil, it is named Camellia oleifera. The camellia oil extracted from camellia oleifera seeds has a clear and fragrant taste, rich nutrition and storage resistance. It is a high-quality edible oil and can also be used as lubricating oil, anti-rust oil and other industrial oils. Tea cakes made from Camellia oleifera are both pesticides and fertilizers, which can improve the water storage capacity of farmland and prevent pests in rice fields. my country is the origin of camellia oleifera, and it is the main woody oil tree species in the south of my country. It is widely planted in mountainous areas and low hilly areas. It can green barren hills and maintain water and...

Problems solved by technology

[0003] Camellia oleifera has a long lifespan and strong planting applicability. It can grow in hills, mountains, and ditch sides. However, if extensive planting and management are performed on soils with shallow soil layers, low fertility, and serious soil erosion, although Camellia oleifera can grow, it will prolong The time period from initial production to full production leads to premature aging and low yield of camellia oleifera and significant characteristics of large and small years, which affect the quality and yield of camellia oleifera; while planting camellia oleifera on deep, loose, fertile, well-drained sandy soil, the yield and oil yield are higher

Camellia oleifera is mostly planted in low mountains and hills in southern my country. The low mountains and hills are mostly red soil, red red soil or loess soil. The surface soil rich in organic matter is shallow, and the thin soil layer is usually compact and heavy, easy to harden, and ventilated. Poor conditions, poor fertility, and strong weathering and leaching effects, weak fertilizer retention capacity, serious soil erosion when it rains, the planted camellia often has low yield and oil yield, and poor economic benefits

[0004] In the prior art, inappropriate methods for the cultivation and planting of camellia oleifera often lead to a longer survival rate of camellia oleifera planting and a longer fruit-hanging period of camellia oleifera, and the oil yield of the camellia oleifera fruit hanging is low. The Chinese invention patent with publication number CN4823740A discloses A method for shaping and pruning Camellia oleifera planting, which provides a method for shaping and pruning Camellia oleifera with two or more main trunks but the main trunks are upright and the main branches are weak, and the trunk is retained, shaped, and the main branches are selected and retained, so as to realize the expansion of crown width , thicken the ground diameter, adjust the tree height, and form an ideal high-yield tree shape

However, this invention needs to go through many times of pruning and shaping, setting the stem, pulling the stem, removing the foot branches, removing sprouts, pruning, thinning branches, cutting off the shoots, etc., and the cycle is long.
