胶东半岛盛产苹果。多年来干旱一直影响苹果的产量。苹果树多半种植于山岗丘陵或河滩地,土质多为沙质,难以实施地面灌溉。近几年通过喷灌试验,对苹果实施喷灌效益较为显著。但是由于苹果树冠高大,移动管道困难,不宜采用半固定式或移动式,搞固定式费用高,须降低成本。 Jiaodong peninsula rich apple. Droughts have affected apple production over the years. Apple trees are mostly planted in hill hills or flood land, mostly sandy soil quality, difficult to implement surface irrigation. In recent years by sprinkler irrigation test, the effect of sprinkling irrigation apples is more significant. However, due to apple tree tall, difficult to move the pipe, should not be semi-fixed or mobile, engaged in fixed-cost, to reduce costs.
