摘要
目前,我国粮食产量的提高,在很大程度上依赖于作物品种的改进、生产技术的提高及科学施肥等因素。化肥的机械化施用技术的发展,关系到我国粮食安全和农业生产与生态环境的协调发展。因地制宜施用肥料已经成为农事活动特别是作物增产措施中一项十分重要的内容。然而,由于我国粮食产量的增长对化肥的依赖性不断增加,导致农业生产与自然环境之间的矛盾不断加剧,施肥技术的正确与否已成为能否实现农业乃至全社会可持续发展和协调发展的关键因素,并已成为政府和社会普遍关注的焦点。因此,正确分析农业生产中化肥的施用现状和装备现状,研究探讨科学、高效的机械化施肥技术,显得十分迫切。
Nowadays, the increase of yields of food crops relies largely on the improvement of the crop breed, planting technique, scientific fertilization, etc. Fertilizing according to local conditions has become one of the most important measures took to increase the production. Because the increase of yields of food crops is more depending on chemical fertilizer, the contradiction between agricultural production and entironment becomes more serious. Whether the fertilization technique is suitable or not has become a key factor in agricultural sustainable development and even social sustainable development. And it also becomes an important element which the government and the society focus on, Analyzing the status quo of the application of chemical fertilizer correctly and researching on the high efficiency technique of mechanized application are very urgent.
