二十九团位于天山南麓塔里木盆地东北边缘,山麓洪积——冲积扇地带,属高水位重盐碱地.开垦前一般一米土层内土壤含盐量3—5%,最高超过10%.经耕种以后,地下水的平均深度为1.9米,灌溉前期2.15米,灌溉期1.45米,地下水矿化度35.5克/升,最高达92.6克/升.从而给造林带来极为不利的因素.从1965年至1977年共栽8316亩,实际保存不到2470亩,保存率仅有29.6%,就是保存下来的林带,亦残缺不齐,生长量极低,有的甚至栽
Twenty-nine regiment is located in the northeastern edge of the Tianshan Tarim Basin, foothills alluvial - alluvial fan zone, is a high water level saline-alkali land. Reclamation of a meter before the soil salt content of 3-5%, up to more than 10%. After cultivation, groundwater has an average depth of 1.9 m, irrigation of 2.15 m, irrigation duration of 1.45 m, groundwater salinity of 35.5 g / l and a maximum of 92.6 g / l, which brings extremely unfavorable factors to afforestation. A total of 8316 acres of planted from 1977 to the present, the actual preservation of less than 2470 acres, the preservation rate of only 29.6%, is the preserved forest belt, also incomplete, very low growth, and some even planted
