Olive trees are based on? High yield, high quality and high efficiency? The rare high-quality woody oil-bearing trees in the world are strongly negative trees, which like to grow in well-drained plots, are drought-tolerant, have strong adaptability to soil, can grow in slightly alkaline sandy loam and calcareous clay, have shallow roots and are cold-resistant, and common varieties can tolerate-12℃ low temperature, while cold-resistant varieties can tolerate-18℃ low temperature, with long life and strong growth ability.

Water and fertilizer management
