近几年来,农户中羊养的数量越来越多,仅长春地区农安、双阳、九台、榆树、德惠五个县和长春市郊区就存栏羊20多万只。现将农民积攒羊粪的经验介绍如下: 一、羊粪尿的性质羊粪含水分少,肥料成分高,易腐熟,属热性肥料。羊粪中含氮0.65%、五氧化二磷0.47%、氧化钾0.23%。羊尿中含氮1.68%、五氧化二磷0.03%、氧化钾2.10%。此外,羊粪尿中还含一些作物生长发育所需的物质。据国外研究,绵羊厩肥中氮素被作物的利用系数达33.6%,是厩肥中最高的。
In recent years, there have been more and more sheep raising in rural areas. Only 200,000 sheep are kept in the five counties of Chang’an, Nong-an, Shuangyang, Jiutai, Yushu and Dehui in Changchun. The experience of farmers to accumulate sheep manure now described as follows: First, the nature of the sheep manure Urine manure less moisture, high fertilizer composition, perishable, is a thermal fertilizer. Sheep manure contained 0.65% nitrogen, phosphorus pentoxide 0.47%, 0.23% potassium oxide. Sheep urine nitrogen 1.68% nitrogen, 0.03% phosphorus pentoxide, potassium 2.10%. In addition, sheep excrement also contains some of the substances needed for crop growth and development. According to foreign studies, sheep manure fertilizer utilization factor of 33.6% by crops, is the highest manure.
