广东省油茶幼林大田平衡施肥技术

Balanced fertilization techniques in the field of Camellia oleifera young plantation in Guangdong

为了给油茶的合理施肥提供理论依据,在大田中对普通油茶、高州油茶、广宁红花油茶幼林进行了不同的施肥处理,分别测定了其树高、地径、冠高、冠幅以及叶片面积、周长、长和宽等指标值。结果表明:最佳的施肥方法是采用有机肥与无机肥相结合、大中微量元素养分相配合的复合营养配方,并根据油茶生长对养分的需求规律分次施用。

In order to provide a theoretical basis for rational fertilization in Camellia oleifera, young plantations of C. oleifera Abel., C. gauchowensis Chang and C. semiserrata Chi. were treated by different fertilization methods in the field, and some indicators were determined, including tree height, ground diameter, crown height, crown width and leaf area, perimeter, length, width, and so on. The results show that organic fertilizer combining with inorganic fertilizer, large, medium and trace elements cooperating, and applying the compound nutrition formula at different times is the best fertilization method, based on nutrient requirements of C. oleifera growth.
