Method for transforming viscous heavy saline soil by constructing side salt leaching channel
The invention relates to a method for transforming viscous heavy saline soil by constructing a side salt leaching channel, which comprises the following steps of: selecting the viscous heavy saline soil in southern Xinjiang, communicating an alkali removal channel network through dredging, and constructing a high-ridge border field; a ditcher divides a whole field into parallel strip-shaped soil bodies perpendicular to a drainage channel, independent units of strip-shaped soil bodies, deep ditches and strip-shaped soil body alternated side salt leaching are built, concealed pipes and gravel materials are arranged, the gravel ditches, the concealed pipes and alkali drainage ditches are communicated, and side salt leaching channels of the field size are built; performing drip irrigation and high-density planting of halophilic plants to cover salt inhibition, and performing deep plowing and returning to the field when the salt absorption amount is maximum; through biological salt absorption, field returning, field soaking in slack season water, retting and field piece side salt leaching circulation, soil salt and plant salt are rapidly and laterally washed, the soil structure is improved, the soil biological fertility is created, pioneer crops can be planted after 2-3 years, and a new way is provided for increasing new cultivated land, fixing civil safety, improving the living environment and promoting local agricultural development.
本发明涉及一种构建侧洗盐通道改造粘重盐土的方法，该方法选择南疆粘重盐土，通过疏浚连通排碱渠网，筑造高埂畦田，开沟机将整个田块分割为垂直排渠的平行的条形土体、建成条形土体‑‑深沟‑‑条形土体相间的侧洗盐的独立单元，布设暗管和砾石料，连通砾石沟‑‑暗管‑‑排碱沟，构建田块尺度的侧洗盐通道；滴灌高密度种植嗜盐植物覆盖抑盐，吸盐量最大时深翻还田；通过生物吸盐、还田、农闲水泡田、沤制及田块侧洗盐循环，不仅快速侧洗土壤盐及植物盐，而且改良土壤结构、营造土壤生物肥力，2‑3年后即可种植先锋农作物，为增加新的耕地、固民安边、改善生存环境，促进当地农业发展提供了一条新的途径。
