肥料是重要的农业生产资料,是农业增产的物质基础。随着农业生产的发展和科学种田水平的不断提高,肥料工作引起人们越来越多的重视。肥料的施用与土地的利用、培肥是密切相关的。农场建设三十年的历史,由开始时单纯依靠自然肥力,到以后逐步增加化肥用量、用多养少,到目前开始走上用养结合、科学合理施肥道路的过程,就是人们对自然规律的认识不断深化的过程。坚持用地养地相结合,在肥料工作上,就要坚持“以有机肥料为基础,有机肥料和化学肥料并重”的方针。农场建设三十年来,随着土地开垦年限的增长,自然土壤不断熟化,加之用地养地没有很好结合,土壤有机质下降很快。据黑龙江垦区调查,开荒初期有机质普遍为7—9%,目前一般为4—5%,最低达2%。解决肥力下降问题,就要认真贯彻肥料工作方针,把有机肥和无机肥结合起来,既利用
Fertilizer is an important means of agricultural production, is the material basis for agricultural production. With the development of agricultural production and the continuous improvement of scientific farming, fertilizer work has drawn more and more attention. Fertilizer application and land use, fertilization is closely related. The thirty-year history of the construction of the farm began with a simple reliance on natural fertility, gradually increasing the amount of chemical fertilizer to be used, and raising more with less, so far it has embarked on a process of combining cultivation and scientific and rational fertilization with people. Understand the deepening process. Adhere to the combination of land and land, fertilizer work, we must adhere to the “organic fertilizer as the basis, organic fertilizer and chemical fertilizer both” approach. In the thirty years since the construction of the farm, with the increase of the land reclamation years, the natural soil is continuously matured, and the land used for cultivation is not well combined, and the soil organic matter decreases rapidly. According to the investigation of Heilongjiang reclamation area, the early organic wasteland generally 7-9%, currently 4-5%, the lowest up to 2%. To solve the problem of fertility decline, we must conscientiously implement the fertilizer guidelines, the organic fertilizer and inorganic fertilizer combine to both use
