How many camellias are planted?
As a characteristic plant with ornamental value and economic value, camellia planting spacing directly affects the later growth trend and field management efficiency. Scientific planning of plant spacing and row spacing can not only improve photosynthetic efficiency, but also reserve space for mechanized operations. In this paper, the standard parameters of different scenes are analyzed systematically by combining terrain characteristics and planting patterns. Camellia tree planting density standard flat and gentle slope land is routinely planted on high-quality plots with a slope of ≤15° and a soil layer thickness of more than 60cm. It is recommended to use a row-plant spacing of 3m×4m. This spacing not only ensures growth space for individual plants, but also forms a 1.2-meter-wide artificial working channel to facilitate daily pruning, topdressing and other operations. Mechanized planting plan Large-scale planting bases can reduce the row spacing to 3.2m and expand the plant spacing to 3.5m. This "wide plant and narrow row" layout allows for a traffic width of 2.8m for rotary tillers, harvesting vehicles and other equipment, and at the same time, staggered arrangement ensures that the planting quantity per mu is ≥65 plants. In the non-intercropping pure forest model, when understory intercropping is not carried out, it is recommended to adopt a golden ratio of 3m ×3.5m. This model controls the crown projection overlap rate at 18%-22%, which can not only form effective shade to inhibit weeds, but also avoid excessive competition for nutrients. Special treatment of thin soil on steep slopes For barren plots with slopes>25° and effective soil layers <40cm, a 3m×3m dense planting method is required. By increasing the planting density by 20% to compensate for growth weaknesses, and combining with fish scale pit planting technology can improve soil and water conservation effects. The planning techniques for per mu of camellia trees are calculated based on standard spacing, and the initial planting density should be maintained at 74-82 plants/mu. During the peak fruiting period, the number is adjusted to 55-60 plants/mu through thinning. At this time, the crown width can reach 4.2 m and the light transmittance between rows is greater than 65%, ensuring high quality and high yield.
Scientific plant spacing design requires overall consideration of terrain characteristics, variety characteristics and management methods. It is recommended to use a total station to accurately set out before planting and reserve 5% of replanting space. By dynamically adjusting planting density, dual improvements in ecological and economic benefits can be achieved.
