为了解我区当前农田肥料投入情况,研究制定今后农田肥料投入措施,1989年冬,我们组织全区各县、市土肥站(组),对当年肥料投入结构情况进行了一次全面调查。并在此基础上,对存在的问题进行了初步分析。一、肥料投入的结构情况1、有机肥:全年有机肥投入总量为2431.5万吨,按播种面积计算,每亩平均1664.95公斤。其中农家肥(包括牲畜圈粪、粪坑垃圾肥、高温堆肥等)占96.77%,秸秆直接还田占3.18%,绿肥占0.04%,饼肥占0.005%。
In order to understand the current input of farmland fertilizers in our district and to study and formulate the measures for inputting farmland fertilizers in the future, in the winter of 1989, we organized all counties and municipal earth stations (groups) in our region to conduct a comprehensive survey on the structure of fertilizer inputs in that year. Based on this, a preliminary analysis of the existing problems is made. First, the structure of fertilizer inputs 1, organic fertilizer: The annual total input of organic fertilizer 24.315 million tons, according to the sown area, an average of 1664.95 kilograms per mu. Among them, 96.77% of farmyard manures (including livestock ring litter, litter pit rubbish, high-temperature compost, etc.) accounted for 96.77%, straw accounted for 3.18%, green fertilizer accounted for 0.04% and cake accounted for 0.005%.
