一、注意疏通沟渠防水害 葡萄根系生长发育要求有充足的氧气,否则就会因无氧呼吸引起根系腐烂、死亡。所以,低洼河滩地种葡萄首先要做好清沟排渍工作。地表渍水可修明沟排,深层积水修暗沟排除。可以用直径15～20厘米多孔水泥管,外包一层纤维类东西深埋在1米以下,既可排水,也可增加土壤通气性;也可行间挖深沟(深1米,宽50厘 First, pay attention to dredging ditch water damage grape root growth and development requires adequate oxygen, otherwise it will be due to anaerobic respiration caused by root rot and death. Therefore, the low-lying floodplain grapes must first clear gutter row of stains work. Surface water can fix ditch rows, deep water repair ditch exclusion. You can use the diameter of 15-20 cm porous cement pipe, a layer of fiber-type things are buried in a deep buried below 1 meter, both drainage, but also increase soil aeration; also feasible ditch deep (1 m deep and 50%
