摘要
本文研究了厩肥、猪、牛、羊、鸡、鸭、兔、蚕粪等8种有机肥料的锌、锰总量及不同形态的含量,同时还研究了有机肥料及土壤中酶的活性,试验证明有机肥料是提供作物锌、锰营养的良好肥源,施用有机肥料可提高土壤锌、锰的有效性,但对土壤中锌、锰的有效化的影响和作用不同,有机肥供锰速度慢,强度小,伹在土壤中的残效长;而供锌强度大,速度快。有机肥与无机化肥配合施用,种植麦、稻两季作物后,在第三季的晚稻土壤中锌出现严重的亏缺。
This paper deels with the total amounts and cintents of different forms of Zn and Mn in eight kinds of organic manure i.e. stable manure, pig, cattle, sheep, chicken, duck, rabbit and silkworm feces. Meanwhile, the activities of different kinds of enzymes in organic manure were also studied. It was shown by experimental results that organic manure was a good fertilizer for providing plants with Zn and Mn nutrients. Organic manure could increase the availability of Zn and Mn in soil, but as to the effect of organic manure on the mobilization of soil nutrients, a difference between Zn and Mn was found. Organic manure was slow and weak in its supplying-intensity of Mn nutrient to plants, but high in residue for providing available Mn to soil. On the contrary, the effect of organic manure on Zn was just opposite to Mn. After planting two crops——barley and rice, with organic manure combined with chemical fertilizer applied to the first crop, a serious deficiency of Zn in the third crop (late rice) was found.
