Embodiment 1

[0039] In 2012, the Camellia oleifera planting area in Shuangfeng County - Jingzi Town was selected, with about 50 mu. The Camellia oleifera forest has been afforested for 25 years, and the management is extensive. In 2012, the agricultural operation of the camellia oleifera forest was as follows:

[0040]1. Ladder-belt land preparation: Excavate a horizontal ladder belt of about 1.0-3.0m along the contour line according to the mountain situation and the distribution of camellia oleifera trees, so that the camellia oleifera trees are located on the terrace to form contour planting. The outside of the ladder surface is high and the inside is low, the outer edge is used as a soil ridge, and the inside of the ladder is opened with bamboo joints.

[0041] 2. Determine the contour line spacing based on the slope and vertical height difference, and plant biological hedgerows at the same height as the slope of the terrace, and the width of each row of hedgerows is 20-60cm. For biol...

Embodiment 2

[0047] In 2011, Chaxi Town, a Camellia oleifera planting area in Xinhua County, was selected, with an area of ​​about 65 mu. The camellia oleifera forest has been afforested for 15 years, and the yield of camellia oleifera per mu is 3-10 kg, while that of "small year" old camellia oleifera is only about 3-5 kg ​​per mu. The Camellia oleifera forest is in the early stage of rich production, and the management level is average. Since 2011, the farming operation of the camellia oleifera forest has been carried out as follows:

[0048] 1. Ladder-belt land preparation: Excavate a horizontal ladder belt of about 1.0-2.0m along the contour line according to the mountain situation and the distribution of camellia oleifera trees, so that the camellia oleifera trees are located on the terrace to form contour planting. The outside of the ladder surface is high and the inside is low, the outer edge is used as a soil ridge, and the inside of the ladder is opened with bamboo joints.

Abstract

Disclosed is a high-yield oil-tea camellia cultivation method. The method include selecting a mountain area or low hilly terrain of a southern oil-tea camellia planting region, dividing a plurality of oil-tea camellia planting regions in the vertical direction of the mountain area or low hilly terrain along the contour, excavating horizontal ladder bands used for planting oil-tea trees into the mountains of each oil-tea camellia planting region, planting biological fences preventing water and soil erosion on slopes between the adjacent oil-tea camellia planting regions, and planting green manure or commercial crops between the lines of the biological fences and the lines of the oil-tea trees of the oil-tea camellia planting regions. By means of fertilizing, loosening the soil, increasing the nutrition storage of oil-tea camellia growth soil layers, improving soil physicochemical property and preventing water and soil erosion, the purposes of promoting the early flowering and more fruiting of the oil-tea camellia, increasing the oil tea yield, improving the oil tea quality and reducing fertilizer and labor force investment can be achieved, and the method can be applied to domestic and international oil-tea production and practice widely.

Description

technical field [0001] The invention relates to a high-yield cultivation method of camellia oleifera. Background technique [0002] Camellia oleifera is the main woody oil tree species in southern my country, and it is widely planted in mountainous areas and low hilly areas. Camellia oleifera oil extracted from camellia oleifera fruit is a pure natural green health-care edible oil with good flavor, good oil quality and high nutritional value. Regular consumption can lower blood cholesterol, and it is called "the king of oils". In recent years, the state and governments at all levels have attached great importance to the development of camellia oleifera industry, and have taken the development of camellia oleifera industry as a strategic measure to improve the structure of people's edible oil and maintain the safety of national oil plants. Therefore, the development of camellia oleifera planting has broad prospects. [0003] Camellia oleifera has wide adaptability, but if it...
