我国农业生产近几年迅速发展,肥料起着重要作用.但目前有机肥不足,国产化肥以低浓度或挥发性品种为主;养分比例不协调,1982年N:P_2O_5:K_2的比例为1:0.24:0.002;化肥分配多头,主要用于各种农副产品的换购,难以因土科学分配;化肥施用因袭传统,大量撒施土表,影响肥效,多种工业废副产品以肥料形式转为农用,其中有一些可能引起污染土质、危害生产的不良后果;由于科普宣传不力,示范推广尚未引起充分重视.为此,根据赵总理“改变化肥结构,实行合理施肥”的指示,谨就加强管理,提高肥料经济效益问题提出如下建议:
The rapid development of agricultural production in China in recent years, fertilizer plays an important role.But at present the lack of organic fertilizer, domestic fertilizer to low concentrations or volatile varieties; nutrient ratio is not coordinated, 1982 N: P_2O_5: K_2 ratio of 1: 0.24: 0.002; Fertilizer allocation long, mainly for the redemption of a variety of agricultural and sideline products, difficult to assign due to soil science; Followed the traditional use of chemical fertilizers, a large number of sprinkle soil table, affecting fertilizer efficiency, a variety of industrial waste by- Some of which may cause pollution of soil, endanger the adverse consequences of production; due to poor popularization of science and technology, demonstration and promotion have not yet given full attention .To this end, according to the “change in fertilizer structure, the rational application of fertilizers,” the directive, I would like to strengthen management and improve Fertilizer economic benefits made the following recommendations:
