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。
In this paper, the total amount of zinc and manganese and the content of different forms of eight kinds of organic manure such as manure, pig, cattle, sheep, chicken, duck, rabbit and silkworm manure were studied. The activity of enzyme in organic manure and soil was also studied. It is proved that organic fertilizer is a good source of fertilizers to provide nutrition of crop Zn and Mn. Application of organic fertilizers can improve the availability of Zn and Mn in soil. However, the effect and role of Zn and Mn in soil are different , Low intensity, long residual effect in the soil; and for zinc strength, fast. Organic fertilizer and inorganic fertilizers with the application of wheat and rice planted two crops in the third season of late rice soil zinc serious deficit.
