关中垆土耕作历史悠久,土层深厚,保水保肥能力较强,增产潜力很大,但一些地方利用不当,引起土壤板结,影响粮棉产量大幅度提高。泾渭等老灌区板结尤为突出,对当前农业生产影响较大。板结的土壤田间耕作困难,适耕时间短,既费工又费力,耗损农具,同时犁起的土垡不易散碎,土块大,造成播种困难,易招致缺苗断条,还影响土壤通气透水及根系发育。1973年合阳孟庄公社党定大队凹地板结的土壤,小麦根系受到阻碍,生长纤细,亩产不足四、五十斤。针对这一问题,调查总结其形成原因和防除 Guanzhong 垆 soil cultivation has a long history, deep soil, strong ability to retain water and fertilizer, a great potential for increase production, but improper use of some places, causing soil compaction, affecting grain and cotton production increased significantly. Jing Wei and other old Irrigation area is particularly prominent, affecting the current agricultural production. Hardening the compacted soils in the field is difficult and time is short for tillage. Therefore, it takes time and labor and consumes farm implements. At the same time, the plowed soil is not easy to be broken and pieces of soil are large, resulting in sowing difficulties. Water permeability and root development. In 1973, Heyang Mengzhuang commune Party decided the brigade concave knot soil, wheat roots were obstructed, growing slender, less than four mu per ten pounds. In response to this issue, the survey concluded its formation and control
