中文摘要:
      通过红花岗区耕地质量地球化学调查评价工作,采集各类样品共2036件,获取数据信息46878项,评价了红花岗区耕地质量地球化学等级特征,结果表明:全区耕地土壤养分综合等级以二等和三等为主,三等及以上占比9638%;耕地土壤环境地球化学综合等级以安全利用类为主,占比8275%;耕地土壤质量地球化学等级以三等为主,三等及以上占比9930%。新发现特色耕地资源有:富硒耕地2379万亩,以三级富硒耕地为主,主要分布在深溪镇;富锗耕地710万亩,占比2812%,各乡镇均有分布;发现绿色富硒水稻16件,绿色富硒玉米1件。通过综合分析,提出耕地规划利用建议:(1)打造以海龙镇上坝村为重点试点区域的绿色优质富硒水稻品牌;(2)推荐优选6块区域进行富硒耕地开发,打造绿色优质富硒农产品基地;(3)根据区域元素缺乏种类,分布范围,有针对性地增补施相应的肥料;(4)对发现的富硒富锗、养分元素缺乏二类重要区域开展详查。
英文摘要:
      2036 samples were collected and 46878 items of data information were obtained through the geochemical investigation and evaluation of cultivated land quality in Honghuagang district,the geochemical grade characteristics of cultivated land quality in the area were evaluatedThe results showed that the comprehensive grades of soil nutrients in cultivated land in the whole region were dominated by the second and third grades,with 9638% of the third grade and aboveThe comprehensive geochemical grade of cultivated land soil environment is mainly safe utilization,accounting for 8275%The geochemical grade of cultivated land soil quality is mainly third grade,with 9930% of third grade and aboveThe newly discovered characteristic cultivated land resources include 237900 mu of selenium rich cultivated land,mainly three-level selenium rich cultivated land,mainly distributed in Shenxi townGermanium rich cultivated land is 71000 mu,accounting for 2812%,which is distributed in all villages and towns16 samples of green Se-enriched rice and 1 sample of green Se-enriched corn were foundThrough comprehensive analysis,some suggestions on planning and utilization of cultivated land are put forwardFirstly,to build a green and high-quality selenium-enriched rice brand with Shangba Village,Hailong Town is as the key pilot areaSecondly,it is recommended to select 6 areas for the development of selenium-enriched arable land to create a green and high-quality selenium-enriched agricultural product baseThirdly,it is suggested to supplement and apply corresponding fertilizers according to the species and distribution range of element deficiencyLastly,it is suggested that detailed investigation should be generally explored in two important areas:selenium and germanium and lack of nutrient elements
