水分对板栗的生长、发育和产量起着重要作用。北方气候干旱,在生产中单纯依靠自然降水,不能满足板栗生长的正常需要,必须进行合理灌溉,补充自然降水的不足,才能达到稳产高产的目的。目前一般的灌溉方法,用水量大,利用率低,养分流失,成本较高。滴灌则可以避免上述缺点。迁西县杨家峪大队在30亩梯田上栽有板栗962株,其中密植园11亩,有板栗树620株,多数为6—7年生的嫁接树。1982年该大队
Water plays an important role in the growth, development and yield of chestnuts. North arid climate, in the production of purely rely on the natural precipitation, can not meet the normal needs of chestnut growth, must be properly irrigated, to supplement the lack of natural precipitation in order to achieve stable and high yield purposes. The current general irrigation methods, water consumption, low utilization, nutrient loss, high cost. Drip irrigation can avoid the above shortcomings. Yangjiayu Qianxi County brigade planted 962 chestnut trees on 30 acres of terraces, of which 11 acres of densely landscaped gardens, chestnut trees 620, mostly 6-7 years old grafted trees. The brigade in 1982
