我场有柑桔面积500亩,1985～1989年分别建于红壤山坡上,坡度在8～12度,目前还没有建立灌溉系统,桔树生长受阻,特别是1991年的异常高温干旱天气长达40多天,大部分桔树叶片转黄并向内卷缩,掉叶现象严重,部分幼果因缺水变黄脱落,未掉的果实在膨大期也因此发育不良,严重影响柑桔产量和品质。针对这种情况,在实践中我场采用竹筒灌水抗旱法,取得了明显的效果,减轻了干旱造成的损失。现将具体作法报告于后:(一)方法一株桔树
My field has a citrus area of 500 acres, 1985-1989 were built on the slopes of red soil slope of 8 to 12 degrees, there is no irrigation system, the growth of obstructed orange trees, especially in 1991, the unusually hot and dry weather up to More than 40 days, the majority of orange leaves turning yellow and curled inward, the leaves off the phenomenon of serious, part of the young fruit due to lack of water yellowing, unfinished fruit in the swollen period and therefore poorly developed, seriously affecting the citrus yield and quality. In response to this situation, in practice, I use the field of bamboo irrigation drought law, and achieved significant results, reducing the losses caused by drought. The specific approach is now reported later: (a) method an orange tree
