20世纪50年代以来,化肥对促进粮食增产和农业丰收起到了非常重要的作用。在作物产量大幅度提高的同时,简单、粗放的施肥方法也带来一系列的问题:比如化肥的浪费、农业成本的增加,更严重的是造成土壤板结、肥力下降、环境污染等。如何做到化肥的减量增效,成为我国整个农业重点关注的问题。黑龙江农垦建三管理局创业农场,是全国农垦农机标准化示范农场、省级平安农场,以种植水稻为主,近几年在水稻施肥技术上进行了很多研究,目前该场示范推广的水稻侧深施肥技术取得了显著成效。本期将对该农场应用这一施肥新技术的情况进行介绍。
Since the 1950s, chemical fertilizers have played a very important role in promoting grain yield and agricultural harvest. Along with the substantial increase in crop yields, simple and extensive application of fertilizers has also brought a series of problems: waste of fertilizers, increase in agricultural costs, and more serious problems of soil compaction, fertility decline and environmental pollution. How to achieve the reduction and efficiency of chemical fertilizers has become the focus of agriculture in China as a whole. Heilongjiang Land Reclamation Bureau three establishments start-up farm, is the national farmland standardization demonstration farm, provincial-level farm, to grow rice-based, rice fertilization in recent years, a lot of technology research, the current demonstration of the rice side of the deep Fertilizer technology has achieved remarkable results. This issue will introduce the application of this new fertilization technology in this farm.
