What is the planting density of Camellia oleifera? Planting management technology

The density of Camellia oleifera in pure forest: row spacing 2.5m, plant spacing 2.5m; or row spacing 3m, plant spacing 2.5m; or row spacing 3m, plant spacing 3m. The planting density of Camellia oleifera in the foothills and flat areas of thick soil: the row spacing is 3m, the plant spacing is 2.5-3m, and about 75-90 plants can be planted per mu. The planting density of Camellia oleifera in areas with poor soil fertility or large slope: row spacing is 3m, plant spacing is 2-2.5m, and about 90-110 plants can be planted per mu.

The planting density of Camellia oleifera should be selected according to the local geological environment, the characteristics of Camellia oleifera varieties and the purpose of management, and the planting density should be selected according to local conditions. The lowest planting density of Camellia oleifera should not be less than 0.6 and the highest should not exceed 0.8.

I. planting density of tea trees

The main results are as follows: 1. when Camellia oleifera is planted in pure forest for the first time, the distance between each plant is 2.5m, the row spacing is 2.5m or the plant spacing is 2.5m, the row spacing is 3m, the plant spacing is 3m and the row spacing is 3m.

2. Camellia oleifera was planted at the foot of the thick soil and in flat places, the distance between each plant was 2.5m-3m, the row spacing was 3m, and 75-90 Camellia oleifera trees were planted per mu.

3. Camellia oleifera was planted in the areas with poor soil fertility and large slope, the distance between each plant was 2m-2.5m, the row spacing was 3m, and 90-110camellia oleifera trees were planted per mu.

II. Management of Camellia oleifera

1. Loosen the soil and weed

(1) weeding and loosening soil should be carried out once when planting, and twice every year thereafter, but weeding and soil loosening is different in each region, generally the first time is between May and June, and the second time is from late August to September.

(2) in high temperature weather, it is not suitable to weed and loosen the soil of Camellia oleifera. Generally, the depth of loose soil is the best in 3m-5m, but in the year of planting, the depth of loose soil should be gradually deepened with the passage of years, gradually from the edge of young trees, shallow digging in loam and deep digging in clay.

2. Fertilization of young forest

(1) if Camellia oleifera is planted in woodland with sufficient base fertilizer, it is not necessary to apply fertilizer in the first year. Camellia oleifera should be fertilized twice a year, slow-acting fertilizer, such as fire soil ash or other mature organic fertilizer, should be applied in winter, and quick-acting fertilizer should be applied in spring, such as urea.

(2) the amount of fertilizer applied per Camellia oleifera tree should not exceed 25g in a year, which can be divided into multiple applications, but the amount of fertilizer applied per plant should not exceed 10g.

3. Shaping of young trees

The most suitable time for Camellia oleifera pruning is in spring, the shade should be removed in time after pruning, and the pruning of young trees should not be overweight.

Dry cultivation: within 1-2 years of planting Camellia oleifera, all the spring shoots of the terminal buds should be preserved so that they can quickly become the trunk.

Setting: 3-4 strong main branches should be left around the trunk 60cm, and the number of secondary branches on each main branch should be determined according to the distance between the two main branches of the tree.

4. Woodland intercropping

The main results are as follows: (1) crops, medicinal herbs, peanuts and beans with short harvest period can be planted among young Camellia oleifera trees, which is beneficial to the growth of Camellia oleifera and can bring harvest in a short time and improve the economic benefit of Camellia oleifera.

(2) the plants that do not win glory, fertilizer and water with Camellia oleifera should be selected. there is an area distance between the planted crops and Camellia oleifera, and tall stalks, vines and crops with high water consumption in dry season should not be planted among Camellia oleifera trees.

5. Harvest

When picking the fruit of Camellia oleifera, the branches of Camellia oleifera can not be broken and picked. After the fruit is picked back, the stacking time should not exceed 5-6 days. It is necessary to spread the sun, turn it over many times in the process of drying, make the Camellia oleifera fruit crack, then clean the sundries in the fruit, collect the Camellia oleifera seeds for storage, and finally press the oil.
