摘要: 利用1970-2004年实测长系列资料分析了朝阳地区降水量和春播期土壤墒情之间的相关关系,结果表明:封冻期(10-11月)降水量与春播期土壤墒情间具有极显著相关关系。因此提出:应该调整人工增雨的思路,通过开展封冻期人工增雨改善朝阳地区春播期的土壤墒情,提高人工增雨的效益和作用。

Abstract: Based onthe observation datain Chaoyang Cityfrom1970 to 2004 ,the relationship betweenthe precipitation andsoil moisture content inthe spring sowingtime was analyzed.The results showedthat the rainfall during soil freezing period(from October to November) had extremely conspicuous mutual relations withthe soil moisture content inthe spring sowingtime .It was suggestedthatthe artificial rainfall should be developedinthe period of soil freezingtoimprovethe soil moisturecontent of the spring sowingin Chaoyang district andto raise the effect and benefit of artificial rainfall .
