春旱是影响我国北方旱区,特别是影响东北西部和内蒙古东部旱区玉米春季播种和安全保苗的主要因素之一。经过大量调查和群众经验总结及1988～1990年的试验、示范和推广证明:在十年九春旱的北方地区,玉米刨埯坐水播种技术,对玉米适时播种,抗旱保全苗、齐苗、壮苗,抗旱夺丰收具有十分显著的效果。一、技术操作程序该项技术主要包括两方面:一是耕作整地施肥技术,二是刨埯坐水播种技术。全套技术可概括为“三犁川打垄,一次深施底肥,刨埯坐水种”。
Spring drought is one of the main factors that affect the spring sowing and safe seedling of maize in the northern part of China, especially in the western part of Northeast China and eastern part of Inner Mongolia. After a large number of surveys and mass experiences and 1988 to 1990 experiments, demonstrations and promotion of proof: In the northern region of nine years of spring drought, corn planing water sowing techniques, timely sowing of corn, drought protection seedlings, Qi Miao, Strong seedlings, drought-resistant harvest has a very significant effect. First, the technical operation procedures The technology includes two aspects: First, land preparation and fertilization technology, and second, planing sow water planting techniques. A full range of technologies can be summarized as “Sili hit Sichuan Ridge, a deep base fertilizer, planing water sit seeding.”
