Method for comprehensively treating saline-alkali soil
The invention relates to the technical field of saline-alkali soil treatment, in particular to a method for comprehensively treating saline-alkali soil. The method comprises the following steps of S1,engineering treatment, namely establishing a modern drainage system; S2, agricultural measures, namely including tillage, soil dressing, fertilization, sowing, crop rotation, intercropping, interplanting and rice planting; S3, biological measures, namely including salt-tolerant crop planting, green manure forage grass planting and afforestation; and S4, chemical measures, namely in the treatmentprocess, insisting on the basis of drainage, comprehensively treating the relationship of drainage, irrigation, storage and supplementation, correctly selecting the critical depth of an underground water level, performing irrigating in the drought period, performing draining in the waterlogging period, controlling the underground water level in the period of salt return, and supplementing a watersource after the underground water level is lowered due to the fact that the water source is filled, so that regional water-salt movement can be in a good state so as to achieve the aim of improving the soil. Engineering measures and various measures such as agriculture and biology are closely combined, a good farmland ecosystem of water, fertilizer, gas and heat necessary for crop growth is established according to local conditions, and the purposes of improving soil fertility and increasing agricultural yield are achieved.
本发明涉及治理盐碱土壤技术领域，尤其为一种综合治理盐碱土壤的方法，S1，工程治理：建立现代化排水系统；S2，农业措施：包括耕作、客土、施肥、播种、轮作、间作、套种、种稻；S3，生物措施：包括种植耐盐作物、绿肥牧草、植树造林；S4，化学措施，通过在治理过程中要坚持以排水为基础，统筹处理好排、灌、蓄、补的关系，正确选定地下水位的临界深度，做到旱能灌、涝能排，返盐期能控制地下水位，而且灌有水源，地下水位下降后有水源可补，能使区域水盐运动处于良好的状态，达到改良土壤的目的，实行工程措施和农业、生物等多种措施紧密结合，因地制宜建立作物生长所必需的水、肥、气、热的良好农田生态系统，达到提高地力、农业增产的目的。
