- 摘要:
- 黑龙江省土壤监测中心在全省范围内共建立了52 个土壤监测点, 其中:国家级监测点12个, 省级监测点40 个, 监测点代表了黑龙江省土壤耕地面积的70 %以上。通过4 年的监测, 我省几大土壤类型的土壤肥力变化有如下规律:(1)土壤有机质基本稳定;(2)土壤中氮素基本平衡, 磷素盈余, 钾素缺;(3)全省土壤施肥水平氮(N):磷(P2O5)):钾(K2O)为1∶1 .12∶0 .70 ;(4)全省施肥水平低于全国施肥水平。
- Abstract:
- :The Heilongjiang provincial moni tor plots have been set up for 4 years .There are 52 soilmonitor plot s in the province , including 12 national level plots and 40 provincial level plots .These soil monitor plots stand for soil that mo re than 70 %cultivated land in Heilong jiong Province .By 4 yearsmonitor , w e have realized varied trend of soil fert ility in major soil ty pes for Heilongjiong province .asfollow s:①The organic mat ter in soil has no varied basically .②The nitrogen is unchanged and thephosphorus is increased , but potassium is less in soil.③The fert ilizer application rate in soil of totalprovincial average is :N∶P∶K =1∶1 .12∶0 .7 .④The fertilized amount in Heilo ngjiong provincial is lessthan the average amount in China
