耕地是恢复和提高土壤肥力的重要措施,是农业生产的基本环节,其主要作用是疏松土壤,恢复土壤的团粒结构,积蓄水分和养分,覆盖杂草和肥料,除灭病虫害,为农作物生长发育创造良好条件。因此,不失时机地搞好耕地作业是保证苗全、苗壮,实现粮食稳产、高产的关键环。耕地有平翻、垄翻、深耕和旋耕。主要农业技术要求是适时耕翻,既能抢农时,又能保证作业质量。耕深适当,深度均匀一致。耕后地表平坦松碎,开闭垄少,无重耕、漏耕,地头、地边整齐。翻垡良好,无立垡、回垡,残株杂草覆盖严密。坡地耕翻时应沿坡的高线进行,防止雨后冲刷土壤。
Cultivated land is an important measure to restore and improve soil fertility. It is an essential part of agricultural production. Its main function is to loosen soil, restore soil aggregate structure, accumulate water and nutrients, cover weeds and fertilizers, remove pests and diseases, and provide crop growth and development Create good conditions. Therefore, without losing the opportunity to do a good job of arable land is to ensure seedlings, Miao Zhuang, to achieve a stable and productive grain key ring. Cultivated land flat turn, ridge turn, deep plow and rotary plowing. The main agricultural technical requirements are timely plowing, both grab the farm, but also ensure the quality of operations. Tilling deep appropriate, uniform depth. Tillage surface flat after tillage, opening and closing ridge less, no heavy tillage, tillage, the ground, the ground neatly. Turn 垡 good, no Li 垡, Hui 垡, stubble weeds covered tightly. Slope tilling should be along the slope of the high line, to prevent the erosion of the soil after the rain.
