油橄榄虽然具有很强的耐旱性,而灌溉却仍然是获得丰产的重要措施之一。在地中海地区的油橄榄园,由于年降雨量常不足以保证丰产的需要,加以降雨量的年分布不均匀,旱季缺水影响植株的生长发育,因此灌溉促进丰产的作用十分明显,一般可增产一倍,至少可增产30％。油橄榄引种到我国以后,引种地区降雨量一般是900～1200毫米,总量比地中海地区多80％左右,即使在 Although the olive has strong drought tolerance, irrigation is still one of the important measures to achieve high yield. In the olive groves in the Mediterranean region, due to the annual rainfall is often not enough to ensure the needs of high yield, to be uneven distribution of rainfall, drought in the dry season affect the growth and development of plants, so the role of irrigation to promote high yield is obvious, Times, at least 30% increase. Olive introduction to our country, the introduction of rainfall is generally 900 to 1200 mm, the total amount of about 80% more than the Mediterranean region, even in the
