一、技术关键与创新点 了解涂层尿素的供氮特点,采用适宜的施肥技术,以取得经济、社会、环境多重效益是本项研究的技术关键。主要创新点是: 1.探索并实践了公益型的农业科研单位,而向大中型企业,选择优势互补的结合点,联合进入国民经济主战场,有力的促进了科研成果转化为生产力,加快了科研成果形成产品进入市场的速度,取得了明显的经济效益,同时也开辟了农业技术服务的新途径。在研究工作中,多部门的合作,发挥各方优势,构成有机整体,联动运作,共同攻关是高效率完成任务的一种先进工作方法。 2.揭示了涂层尿素在石灰性土壤中的转化移动规律,明确了涂层尿素比等量普通尿素氮素利用率高。
First, the technical key and innovation Understanding of urea nitrogen coating characteristics, the use of appropriate fertilization technology to obtain economic, social and environmental benefits is the key to this study. The main innovations are as follows: 1. To explore and practice public welfare agricultural research institutes, and to large and medium-sized enterprises, select the complementary advantages of each other and jointly enter the main battlefield of national economy, which effectively promoted the transformation of scientific research into productive forces and accelerated Scientific research results in the speed at which products enter the market, and significant economic benefits have been achieved. Meanwhile, new ways for agricultural technical services have also been opened up. In the research work, multi-sectoral cooperation, giving full play to the strengths of all parties, forming the organic whole, linking up and working together and tackling problems together are an advanced method of work for accomplishing tasks with high efficiency. Revealed the movement of coated urea in calcareous soil, and clarified that coated urea had higher utilization rate than normal urea nitrogen.
