为探讨池杉在洞庭湖冲积平原土壤PH值大、地下水位高、地面多积水条件下的适应能力及其速生丰产水平,我们对国营千山红农场一九七六年冬从武汉市红山区利引种的五万株池杉苗,进引池杉丰产试验。一、试验地概况国营千山红农场地处湖北洞庭湖冲积平原大通湖垦区。北纬29°4′—29°10′,东经112°22′—112°30′,属中亚热带向北亚热带
In order to investigate the adaptability of Cryptomeria fortunei in the alluvial plain of Dongting Lake with high PH value, high groundwater level and groundwater accumulation conditions and its fast-growing and high-yielding status, Mountain introduced 50 000 plant fir seedlings, into the pond longevity yield test. First, the experimental site Overview Qian Shan red farm is located in Hubei Dongting Lake alluvial plain Chase reclamation area. Latitude 29 ° 4’-29 ° 10 ’and longitude 112 ° 22’-112 ° 30’E, belonging to the subtropical northward subtropical zone
