我场建立于一九五三年。耕地属荒漠盐碱灰钙土,含盐一般为1—3%(表层0—100厘米),以硫酸盐为主,氯化盐次之。地下水位一般为1.5—2米,矿化度20克/升左右。我们在与盐碱土作斗争中,把大量植树造林作为一项重要措施。到一九六四年,已有林木面积6,840亩。十一年的造林分为两个阶段:一九五四至一九五七年为第一阶段,造林1,090亩,没有做到因地制宜地选择树种,机械地搬用外地的林带结构(杨、榆、白腊混交),以致林带内青一块、白一块,残缺不全。第二阶段自一九五八年起,场党委亲自挂帅,吸取前阶段的经验教训,以耐盐的沙枣为主要树种,并实行土地小畦化,渠系专用化,管理人员专业化,效果较好,获得了如下经验。
My field was established in 1953. Cultivated land is a desert saline alkali soil, salt is generally 1-3% (surface 0-100 cm), mainly sulfate, followed by chloride. Groundwater level is generally 1.5-2 meters, salinity 20 g / l or so. In our struggle against saline-alkali soil, we have made massive tree planting and afforestation an important measure. By 1964, there will be 6,840 mu of forest area. The eleven-year afforestation is divided into two stages: the first stage from 1954 to 1957, afforestation of 1,090 mu, failing to select tree species according to local conditions and mechanically moving the forest belt structure in other places (Yang, Yu, White mixed), resulting in a blue forest, white, incomplete. The second phase Since 1958, party committees in person have taken the lead in taking lessons from the lessons learned in the previous stage, using salt-tolerant dates as the main tree species, and implementing land reclamation, canalization, specialized management, The effect is better, got the following experience.
